5. A helicopter is exerting a force of 100,000 newtons. What is its mass
if it is accelerating at a rate of 100 m/s??

When the net force of a moving object suddenly becomes zero and remains zero, the object will continue at a constant velocity without any changes in its speed or direction.

The correct answer is option C.

When the net force of a moving object suddenly becomes zero and remains zero, the object will continue at a constant velocity. This is described by Newton's first law of motion, also known as the law of inertia.

According to Newton's first law, an object in motion will continue moving at a constant velocity in a straight line unless acted upon by an external force. In this case, when the net force becomes zero, there are no external forces acting on the object to change its motion.

If the object was initially moving at a constant velocity, it will continue moving at that same velocity. If it was accelerating or decelerating before the net force became zero, it will maintain its current velocity without any further changes.

The reason for this behavior is that the object has no force acting on it to cause an acceleration or deceleration. Therefore, it will not experience any change in its speed or direction.

Therefore, from the given options the correct one is option C.

The exact magnitude of the force (in N) exerted by the system of charges on the 10 C charge is 88 N.

The exact magnitude of the force (in N) exerted by the system of charges on the 10 C charge is calculated by applying Coulomb's law as follows;

F = kq²/r²

where;

Since the charged is fixed, the distance will be constant, and the new equation becomes;

kq² = Fr²

q² = Fr²/k

q = √ ( Fr²/k )

q = √F x  √ (r²/k)

q₁/√F₁ = q₂/√F₂

when the new charge is 10 C, the new force is calculated as;

√F₂ = ( q₂ x √F₁ ) / q₁

√F₂ = ( 10 x √22 ) / 5

√F₂ = 9.38083

F₂ = (9.38083)²

F₂ = 88 N

Approximately 100 million times greater is the atmospheric pressure in jupiter's core than on earth's surface.

The average  atmospheric pressure at sea level at 15 degrees Celsius is the unit of measurement known as an atmosphere. 1,013 millibars is equal to 760 millimeters of mercury, or 29.92 inches, in one atmosphere. When the bulb is pressed, air from the tube and bulb escapes as bubbles. The liquid's surface does, however, experience atmospheric pressure. The water moves inside the tube when we release the bulb. The pressure that the air around us puts on us is known as air pressure, whereas the pressure that the atmosphere puts on the earth is known as atmospheric pressure. Mercury barometer is used to measure atmospheric pressure, while tore gauges are used to measure air pressure. Since our internal pressure is roughly equal to the external atmospheric pressure, we are not affected by the pressure of the atmosphere around us.

Answer:

it is 1 / square root of the change in distance

Explanation:

since the equation of the gravitational force is

\(F=G{\frac{m_1m_2}{r^2}}\)

then F and r are inversely related, by the equation

\(F \alpha \frac{1}{r^2}\)

this means when F is multiplied by 2 then r^2 is multiplied by half

so when r is multiples by half we first square the number (0.5) ^ 2 = 0.25

so

\(F \alpha \frac{1}{(0.25)r^2}\)

which means F is multiples by 1/0.25 or 4 when the radius is halfed

For, the resistances are related by:
R_A/R_B = L_A/L_B = 2
Since R_A = 8R_ B is the only choice that satisfies this equation, the answer is: a. R_A = 8R_B

To solve this problem, let's consider the properties of cylindrical copper wires, mass, and resistances.

Given that both wires have the same mass, and Wire A is twice as long as Wire B, we can say:
Length of Wire A = 2 * Length of Wire B

Since the mass is the same for both wires, we can express the mass in terms of volume and density:

mass = volume * density

For cylindrical objects, the volume can be expressed as:
volume = π * radius² * length

Since both wires have the same mass and are made of copper, their density is also the same. Let's set their volumes equal:

π * radius_A² * length_A = π * radius_B² * length_B

Now, let's use the fact that length_A = 2 * length_B:

π * radius_A² * 2 * length_B = π * radius_B² * length_B

Divide both sides by (π * length_B) to isolate the radii:

2 * radius_A² = radius_B²

Now let's find the resistances using the formula for the resistance of a cylindrical wire:

R = ρ * (length / (π * radius²)), where ρ is the resistivity of the material.

For Wire A, we have:

R_A = ρ * (2 * length_B / (π * radius_A²))

For Wire B, we have:

R_B = ρ * (length_B / (π * radius_B²))

Now, let's find the relation between R_A and R_B. Divide R_A by R_B:

R_A / R_B = (ρ * (2 * length_B / (π * radius_A²))) / (ρ * (length_B / (π * radius_B²)))

Cancel out the ρ and length_B:

R_A / R_B = (2 / (radius_A²)) / (1 / (radius_B²))

Now let's recall that 2 * radius_A² = radius_B²:

R_A / R_B = (2 / (radius_A²)) / (1 / (2 * radius_A²))

Simplify:

R_A / R_B = (2 * (2 * radius_A²)) / (radius_A²) = 4

So, the correct answer is:

R_A = 4R_B, which is option b.

Answer:

A.

Explanation:

That's the answer

Answer:

Explanation:

If a force of 20N is situated at 30° south west, the x and y component of the vector will be expressed as:

Fx = -Fcos 30° and Fy = -Fsin30°

They are but negative because the force acts in the third quadrant of a four cardinal point

Fx = -20cos30°

Fx = -20(√3/2)

Fx = -10√3N

Hence the -x component if the force is -10√3N

Fy = -20sin30°

Fy = -20(1/2)

Fy = -10N

Hence the y-component is the vector is -10N

The minimum force (Fmin) required to move the block up the ramp is 12.7 N.

Mass of the block (m) = 3.3 kg

Angle of the ramp (θ) = 37°

Coefficient of friction between the block and the ramp (μg) = 0.44

Coefficient of kinetic friction between the block and the ramp (uk) = 0.30

Step 1: Resolve the forces acting on the block.

The weight of the block (mg) can be resolved into two components:

- The force acting parallel to the incline (mg*sinθ)

- The force acting perpendicular to the incline (mg*cosθ)

Step 2: Calculate the force of friction.

The force of friction can be calculated using the equation:

Force of friction (Ff) = μg * (mg*cosθ)

Step 3: Determine the minimum force required.

To move the block up the ramp, the applied force (Fapplied) must overcome the force of friction.

Thus, the minimum force required (Fmin) is given by:

Fmin = Ff + Fapplied

Step 4: Substitute the given values and calculate.

Ff = μg * (mg*cosθ)

Fmin = Ff + Fapplied

Now, let's calculate the values:

Ff = 0.44 * (3.3 kg * 9.8 m/s² * cos(37°))

Ff ≈ 12.717 N

Fmin = 12.717 N + Fapplied

Therefore, the minimum force (Fmin) required to move the block up the ramp is approximately 12.7 N.

(b) The final temperature is 546.15 K.

(c) The total internal energy change of the fluid during this process is 515.4 kJ.

(d) The process can be represented as an isochoric heating process on the P-v diagram and as an isobaric expansion process on the T-v diagram.

(a) To find the initial temperature, we can use the saturated steam tables. At a pressure of 200 kPa, the corresponding saturation temperature is 373.95 K.

(b) Since the volume doubles, the process is an isochoric (constant volume) heating process. Using the ideal gas law, we can determine the final temperature. The initial and final volumes are related by the equation V_final = 2V_initial. Since the mass remains constant, the specific volume (v) is inversely proportional to the density (ρ). Therefore, ρ_final = ρ_initial/2. Using the ideal gas law, we can calculate the final temperature to be 546.15 K.

(c) The total internal energy change can be calculated using the equation ΔU = mC_vΔT, where m is the mass of the fluid and C_v is the specific heat at constant volume. Given the mass as 0.5 kg, the specific heat of water at constant volume, and the temperature change, we can find that the total internal energy change is 515.4 kJ.

(d) On the P-v diagram, the process is represented as a vertical line at 200 kPa, indicating constant pressure. On the T-v diagram, the process is shown as an upward-sloping line, indicating an isobaric expansion process. The initial state is represented as a point on the left, and the final state is represented as a point on the right.

The answer is a. 30. for most of the year, the moon rises, on average, minutes later each evening.

The moon appears to rise later each day due to its orbit around the Earth. The moon takes about 27.3 days to orbit the Earth, and as it orbits, it moves eastward relative to the stars. However, the Earth is also rotating from west to east, so the moon appears to move westward relative to the Earth's surface. This means that each day, the moon rises about 50 minutes later than it did the day before. However, this is an average value and can vary depending on the time of year. During certain periods, such as around the equinoxes, the time difference between moonrises can be closer to 30 minutes, while during other times, such as around the solstices, it can be closer to 70 minutes.

In physics, a system is said to be in equilibrium when neither its internal energy state nor its state of motion tend to vary over time. If all of the forces operating on a single particle are vector summated to zero, equilibrium occurs.

In physics, tension is the pulling force that is conveyed axially by a string, cable, chain, or other similar one-dimensional continuous item, or by either end of a rod, truss member, or other similar three-dimensional object.

Equilibrium refers to the state of a system when neither its internal energy state or state of motion tend to change over time. Equilibrium for a single particle occurs when the vector sum of all force acting on the particle is zero.

Rolanda needs to advise her friend to place the note about mass in region z and the note about charge in region x to fix the mistake in the Venn diagram. Therefore, the correct answer is option A.

Rolanda should suggest to her friend that the note about mass belongs in region z, and the note about charge belongs in region x. This correction is necessary because gravitational force depends on mass, while electrical force depends on charge.

The x in the circle on the left with infinite reach and depends on mass is incorrect because gravitational force does not have infinite reach. It only acts between objects with mass that are in close proximity to each other. The y in the intersecting area is also incorrect because there is no force that is common to both gravitational and electrical forces.

On the other hand, the z in the circle on the right with depends on charge is correct because electrical force depends on the charge of the objects involved. By suggesting that the note about mass belongs in region z and the note about charge belongs in region x, the Venn diagram will accurately represent the differences between gravitational and electrical forces.

In summary, Rolanda should suggest to her friend that the note about mass belongs in region z and the note about charge belongs in region x. Therefore, the correct answer is option A.
