which of the following is not a barrier to physical activity it is fear of injury I think.

1/do + 1/di = 1/f

blah blah blah why does the answer have to be 20 characters long

Answer: Force

In physical science, a force is something that acts on an object by pushing or pulling it. If the force is strong enough, it changes the position or shape of the object. Forces such as friction, air resistance and simple physical contact touch the object directly, while forces like gravity, magnetism and electrostatics act on the object from a distance. Force is a vector quantity, meaning you can measure both its strength and its direction. The formula to find the measure of a force is force = mass times acceleration, written as f = ma.

Velocity

The faster something is moving, the higher its velocity.

When an object is moving, one way to measure how fast it is moving is by finding its velocity, which is the rate at which it is changing position. Like force, velocity is a vector quantity, so it includes direction. To find the average velocity of an object, divide the change in its position by the time the movement took, and state its direction. For example, if a car is driving north and in one hour's time it travels 30 miles, its velocity is 30 miles per hour, north.

Explanation:

From the question we are given the following:

initial speed u = 50m/s

acceleration a = -15m/s²

final speed = 0m/s

Required

Stopping distance S

Using the equation of motion:

0² = 50²+2(-15)S

0² = 2500 - 30S

-2500 = -30S

S = 2500/30

S = 83.3m

Answer: E = 5.004*10^(20) joules

Explanation:

We do not have a lot of information about the impact, so we can assume that the energy released on the impact was the kinetic energy of the large fragment.

Remember that the kinetic energy of an object of mass M that moves at a velocity V is:

K = (M/2)*V^2

in this case, we know that the speed (that is equivalent to the velocity) is:

V = 60,000 m/s

And the mass is:

M = 1.39*10^(11) kg

Then the kinetic energy of the large fragment was:

K = (1.39*10^(11) kg/2)*( 60,000 m/s)^2 = 5.004*10^(20) joules.

Then we could conclude that the energy released on the impact was:

E = 5.004*10^(20) joules

The electric charge of an atom is found by adding the charges carried by its protons and electron.

The mass of an atom is primarily determined by the number of protons and neutrons it contains, since these particles contribute most of the atom's mass. Electrons, which are much lighter than protons and neutrons, contribute only a small fraction of the atom's total mass. Therefore, to determine the mass of an atom, you add the number of protons and neutrons it has.

In a neutral atom, the number of protons and electrons is equal, so the overall electric charge is zero. However, if an atom gains or loses electrons, it becomes charged and is called an ion. If an atom loses electrons, it becomes positively charged (since it has more protons than electrons), while if it gains electrons, it becomes negatively charged (since it has more electrons than protons). Therefore, to determine the electric charge of an atom, you add the charges carried by its protons and electrons.

The magnitude of the frictional force between the sled and the snow is 46.3 N.

We are given that the pulling force has a horizontal component of 21 N and a vertical component in the upwards direction of 25 N. Using this information, we can calculate the magnitude of the pulling force as follows:

Magnitude of the pulling force = √((21 N)² + (25 N)²)

= √(441 N² + 625 N²)

= √(1066 N²)

= 32.7 N

To calculate the force of friction, we first need to calculate the net force. We can do this by finding the difference between the pulling force and the weight of the sled and child:

Net force = Magnitude of the pulling force - Weight of the sled and child

= 32.7 N - 79 N

= -46.3 N

Now, we know that this net force is equal to the force of friction:

The critical depth in the hydraulic jump can be calculated using the specific energy equation. In this case, with a flow rate of 1.17 m³/s, channel width of 1.7 m, and a depth of 149 mm, the critical depth can be determined.

To calculate the critical depth in the hydraulic jump, we can use the specific energy equation, which relates the flow rate, channel dimensions, and water depth. The equation can be written as:

E = (Q² / (2g)) + (y² / (2g)) + (A² / (P * g))

Where:

E is the specific energy,

Q is the flow rate,

g is the acceleration due to gravity,

y is the water depth,

A is the cross-sectional area of flow,

P is the wetted perimeter of the channel.

In this case, we have a flow rate of 1.17 m³/s, a channel width of 1.7 m, and a depth of 149 mm (or 0.149 m). We need to find the critical depth, which occurs at the hydraulic jump. At the critical depth, the specific energy reaches its minimum value.

To determine the critical depth, we need to set the derivative of the specific energy equation with respect to the water depth equal to zero and solve for y. This will give us the critical depth. However, calculating the critical depth requires knowing additional parameters such as the cross-sectional area and wetted perimeter, which are not provided in the given information. Without these values, it is not possible to calculate the critical depth accurately.

Answer:

1.  Current in the circuit; 1.2 Amps

See attached image for the circuit.

2.  Equivalent resistor = 3 Ω

I = 0.3 amps

Potential difference across the battery terminals is: 0.9 V

Explanation:

Part 1.

The internal resistance of 2 ohms is simply added to the circuit in series as shown in the attached image.

Since now we have two resistances in series (2 ohms and 3 ohms) the total of this series combination is 5 ohms. Using Ohm's law, we can derive the current running through the circuit:

\(V=I\,\,R\\6\,V=I\,(5\,\Omega)\\I=\frac{6}{5} \,amps\\I=1.2\,\,amps\)

Part 2.

Now we have a 1.5 V battery with a 2 ohm internal resistance, connected to two identical 6 ohm resistors.

a. The equivalent resistance presented by the two resistors in parallel:

\(\frac{i}{R_e} =\frac{1}{6\,\Omega} + \frac{1}{6\,\Omega} =\frac{1}{3\,\Omega} \\R_e=3\,\Omega\)

b. Now the circuit can be represented by a 2 ohm resistor (internal battery resistance) plus a 3 ohm parallel equivalent resistor in series. That is a 5 ohm total resistance. Then Ohm's law becomes:

\(V=I\,\,R\\1.5\,V=I\,(5\,\Omega)\\I=\frac{1.5}{5} \,amps\\I=0.3\,\,amps\)

c. The potential difference across the battery terminals must be the battery's EMF minus the potential drop in its internal resistance:

\(1.5\,V - (0.3\,\,amps)\,(2\,\Omega)=(1.5-0.6)\,V=0.9\,V\)

Answer:

A screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force.[1] It is one of the six classical simple machines. The most common form consists of a cylindrical shaft with helical grooves or ridges called threads around the outside.[2][3] The screw passes through a hole in another object or medium, with threads on the inside of the hole that mesh with the screw's threads. When the shaft of the screw is rotated relative to the stationary threads, the screw moves along its axis relative to the medium surrounding it; for example rotating a wood screw forces it into wood. In screw mechanisms, either the screw shaft can rotate through a threaded hole in a stationary object, or a threaded collar such as a nut can rotate around a stationary screw shaft.[4][5] Geometrically, a screw can be viewed as a narrow inclined plane wrapped around a cylinder.

Discussion: Two-Dimensional Motion, Forces, and Newton's Third Law is as follow:

Let's take a real-world example of a bird flying and discuss the Two-Dimensional Motion, Forces, and Newton's Third Law of it:

When birds fly, they flap their wings in such a way that air is forced to move down. Due to this downward force, an upward reaction force is exerted on the bird by the air according to Newton's Third Law of Motion. This upward force is what keeps the bird afloat and allows it to soar.

The bird is pushed forward by the air as a result of this exchange of forces. This is due to the fact that the forward motion of the bird is equal to the opposite reaction to the force pushing the bird backward. The bird will slow down if the force pushing it backward is greater than the force of motion. This force can be counteracted by the bird flapping its wings with more force.

The bird can move in all directions, including up, down, forward, backward, and even diagonally. When the bird is changing directions or speed, it's not moving in a straight line, implying that more than one force is acting on it.

These forces may come from a variety of sources, including the bird's own muscles and the air around it. These forces can be difficult to measure and quantify, making it difficult to precisely predict a bird's flight.

A skydiver weighing 180 lb (including equipment) falls vertically downward from an altitude of 5000 ft and opens the parachute after 10 s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.75|v| when the parachute is closed and is of magnitude 12|v| when the parachute is open, where the velocity v is measured in ft/s.

a. The speed of the skydiver when the parachute opens is 71.06 m/s.

b. The distance fallen before the parachute opens is 1,610 ft.

c. The limiting velocity \(v_L\) after the parachute opens is 66.71 m/s.

a. To find the speed of the skydiver when the parachute opens, we can use the concept of net force and Newton's second law of motion. The net force acting on the skydiver is given by:

\(F_n_e_t = m * a,\)

where \(F_n_e_t\) is the net force, m is the mass of the skydiver, and a is the acceleration.

Initially, during free fall, the net force is the difference between the weight of the skydiver and the force of air resistance:

\(F_n_e_t = m * g - F_a_i_r\)

where g is the acceleration due to gravity.

When the parachute opens, the force of air resistance changes to 12|v|, where v is the velocity of the skydiver.

For free fall:

\(m * g - F_a_i_r_c_l_o_s_e_d = m * a,\)

When the parachute opens:

\(m * g - F_a_i_r_o_p_e_n = m * a,\)

Since both equations are equal to m * a, we can set them equal to each other:

\(m * g - F_a_i_r_c_l_o_s_e_d = m * g - F_a_i_r_o_p_e_n\\F_a_i_r_o_p_e_n - F_a_i_r_c_l_o_s_e_d = m * g\).

Substituting the given values:

12|v| - 0.75|v| = 180 lb * g,

11.25|v| = 180 lb * g.

Converting the weight from lb to kg:

m = 180 lb * (1 kg / 2.205 lb) ≈ 81.63 kg.

Converting the acceleration due to gravity from ft/s² to m/s²:

g = 9.8 m/s².

11.25|v| = 81.63 kg * 9.8 m/s².

Solving for |v|:

|v| = (81.63 kg * 9.8 m/s²) / 11.25 ≈ 71.06 m/s.

Therefore, the speed of the skydiver when the parachute opens is approximately 71.06 m/s.

b. To find the distance fallen before the parachute opens, we can use the equation of motion:

\(d = v_0 * t + (1/2) * a * t^2\)

where d is the distance fallen, \(v_0\)is the initial velocity, t is the time, and a is the acceleration.

In this case, the skydiver falls for 10 s with an initial velocity of 0 ft/s and an acceleration of g. Substituting the values:

d = 0 ft/s * 10 s + (1/2) * (32.2 ft/s²) * (10 s)² ≈ 1,610 ft.

Therefore, the distance fallen before the parachute opens is approximately 1,610 ft.

c. The limiting velocity (\(v_L\)) is the maximum velocity the skydiver can reach after the parachute opens. It occurs when the force of air resistance is equal in magnitude to the weight of the skydiver.

\(m * g = F_a_i_r_o_p_e_n.\)

Substituting the given values:

180 lb * g = 12|\(v_L\)|.

Simplifying the equation:

|\(v_L\)| = (180 lb * g) / 12.

Converting the weight from lb to kg:

m = 180 lb * (1 kg / 2.205 lb) ≈ 81.63 kg.

Converting the acceleration due to gravity from ft/s² to m/s²:

g = 9.8 m/s².

|\(v_L\)| = (81.63 kg * 9.8 m/s²) / 12 ≈ 66.71 m/s.

Therefore, the limiting velocity (\(v_L\)) after the parachute opens is approximately 66.71 m/s.

Electric current is the flow of electric charge through a conductor. This flow of charge can occur in different ways, resulting in different types of current. In direct current (DC), the electrons move at an even rate and flow only in one direction. In other words, the flow of charge is unidirectional, from the negative terminal to the positive terminal of a source of electricity, such as a battery or a generator.

In a DC circuit, the direction of the current remains the same over time, unlike in alternating current (AC) circuits, where the direction of the current changes periodically. DC is commonly used in electronic devices and equipment that require a constant and reliable flow of electrical energy. For example, batteries, electronic circuits, and some motors use DC.

DC is also used in certain applications where the flow of current needs to be controlled in one direction only. For example, in electroplating, where a metal is deposited onto a surface by an electric current, DC is used to ensure that the metal ions move in one direction only and are deposited uniformly on the surface.

In summary, DC is a type of electric current in which the flow of electrons is unidirectional, moving from the negative to the positive terminal of a source of electricity. It is commonly used in electronic devices and equipment that require a constant and reliable flow of electrical energy.
