A ball is thrown into the air. At the moment the ball has reached its highest location, the ball has zero___ with non-zero acceleration

Answer:

I think A because inertia is the amount of potential energy right? hope this helps :)

Explanation:

Answer:

Electric potential energy

Explanation:

The Electric potential energy of a system is less than that carried out by electrostatic forces during the development of the system (as long as charges are initially cut infinitely).

The change in potential energy between an initial and final configuration  is equal to minus the work done by the electrostatic forces.

In this problem, we are going to solve for the average speed and average velocity for the entrire trip made by the dolphin.

Given data

speed v= 2 m/s

time t= 24s

the distance travelled by the dolphin is

speed= distance/time

distance= speed*time

distance= 2*24

distance= 48m

now the dolpine made a reverse and covered this 48m in 8s to return to it initial position

the speed it took is

speed= distance/time

speed= 48/8

speed= 6m/s

It average speed is the total distance divided by the total time taken

average speed= (48+48)/(24+8)= 96/32= 3m/s

average speed= 3 m/s

it average velocity is the sum of the initial and final velocity is divided by 2 to find the average

(2+6)/2= 8/2= 4m/s

average velocity is 4m/s

At a rock concert, the sound intensity 1. 0 m in front of the bank of loudspeakers is 0. 10 W/m2. A fan is 30 m from the loud speakers. Her eardrums have a diameter of 8. 4 mm.The sound energy transferred to each eardrum in 1.0 second is 4.36 x 10^-11 J.

The sound intensity at a distance of 30 m from the loudspeakers can be calculated using the inverse square law:

I = I₀ / (4πr²)

where I₀ is the sound intensity at a distance of 1.0 m from the loudspeakers, r is the distance from the loudspeakers, and π is the mathematical constant pi (approximately 3.14).

Substituting the given values, we get:

I = 0.10 W/m² / (4π(30 m)²) = 7.87 x 10^-7 W/m²

The sound energy transferred to each eardrum in 1.0 second can be calculated using the formula:

E = A × t × I

where A is the area of the eardrum, t is the time, and I is the sound intensity.

The area of the eardrum can be calculated using the formula for the area of a circle:

A = πr²

where r is the radius of the eardrum, which is half the diameter.

Substituting the given values, we get:

A = π(8.4 mm / 2)^2 = 5.54 x 10^-5 m²

Substituting the given values and solving for E, we get:

E = 5.54 x 10^-5 m² × 1.0 s × 7.87 x 10^-7 W/m² = 4.36 x 10^-11 J

Therefore, the sound energy transferred to each eardrum in 1.0 second is 4.36 x 10^-11 J.

Answer:

The work completed is 73.5 Joule

Explanation:

Mechanical Work

Mechanical work is the amount of energy transferred by a force that moves an object by a certain distance. It's a scalar quantity, with SI units of joules.

Being  the force and  the displacement the work is calculated as:

W=F.s

The box of m=5 kg is lifted by a distance of s=1.5 m. The force applied to lift the box is equal to the weight of the box, assuming it's lifted at a constant speed, thus:

F = mg = 5 * 9,8 = 49 N

The work is:

W = 49 N * 1.5 m

W = 73.5 J

The work completed is 73.5 Joule

An endless spring A block with mass m is connected to a constant k. The block undergoes a displacement x as a result of the spring. then, by using\((K+U)_{i} =(K+U) _{f}\), we can  determine how much effort the spring performs on the block

It is used to determine a spring's stability or instability and, as a result, what system it should be used in. It reworks Hooke's Law and is mathematically expressed as k = - F/x.

where k is the spring constant, F is the force applied over x, and x is the displacement generated by the spring in N/m. Fs = -kx, where F is the spring's restoring force, k is the spring constant, and x is the displacement, is the formula utilized by the Hooke's Law Calculator.

Explanation:

To find the impedance seen by the source and the current coming out of the source, we can use phasors and  we need to determine the impedance

First, let's convert the given voltage function v(t) = 10 sin(2π100t) into phasor form.

The phasor representation of a sinusoidal function is given by V = A∠θ, where A is the amplitude and θ is the phase angle.

In this case, the amplitude A = 10 and the phase angle θ = 0° (since there is no phase shift mentioned in the question).

So, the phasor representation of v(t) = 10 sin(2π100t) is V = 10∠0°.

Next, we need to calculate the impedance seen by the source. The impedance (Z) is given by the ratio of the phasor voltage (V) to the phasor current (I): Z = V/I.

Since the source voltage is V = 10∠0°, we need to find the phasor current (I).

Using Ohm's law, we know that V = IZ, where Z is the impedance. Rearranging the equation, we have I = V/Z.

Now, we need to determine the impedance Z. For this, we need additional information like the circuit configuration or the values of the resistors, capacitors, or inductors in the circuit. Without this information, it is not possible to find the impedance and the current accurately.

Neon has a complete outermost shell whereas sodium has an incomplete outermost shell.

All noble gases are nonreactive because of the complete outermost shell. It is non-reactive. It doesn't form compounds with any other atom. Just like helium and argon, neon floats around. It is non-reactive because its shells are complete.

While on the other hand, the sodium atom has an incomplete outermost shell which leads to the reactive nature of sodium. Atoms of neon won't form covalent shapes and share electrons because they have a complete outermost shell. So the statement that describes why atoms of neon do not form ionic bonds is that atoms of neon already have a stable outermost shell.

So we can conclude that Neon has a complete outermost shell due to which it is nonreactive.

Neon has a filled octet thus it does not bond to the other atoms of elements.

It is extremely non-reactive, just like all noble gases. So much so that it doesn't combine with anything to form compounds. Similar to helium (He) and argon (Ar), neon is a gas that floats on its own. Since its shells are completely full, it is not reacting.

Neon atoms already have a complete outer shell, thus they won't form covalent structures or share electrons. Therefore, the idea that neon atoms already have a stable octet in their outer shell explains why these atoms do not form ionic connections.

m = 60 [kg] (mass on the moon)

Explanation:

We must remember that the mass is conserved, that is, it remains the same regardless of where it is located.

The only variation is the weight, which is different from the mass. Weight is determined by means of the product of mass by gravitational acceleration.

Therefore the mass of 60 [kg] on Earth will be the same mass on the moon.

(a) The magnitude of the electric field produced by a charge of 4.50 mC at a distance of 1.00 m can be calculated using Coulomb's law.

Coulomb's law states that the electric field strength (E) is directly proportional to the magnitude of the charge (q) and inversely proportional to the square of the distance (r) between the charge and the point of interest.

Mathematically, E = k*q/r^2, where k is the electrostatic constant. The magnitude of the electric field produced by a charge of 4.50 mC at a distance of 1.00 m is 4.05 x 10^6 N/C.

The magnitude of the electric field produced by a charge of 4.50 mC at a distance of 1.00 m can be calculated using Coulomb's law. Plugging in the values, we have E = (9 x 10^9 N m^2/C^2) * (4.50 x 10^-3 C) / (1.00 m)^2 = 4.05 x 10^6 N/C.

The MOI (mechanism of injury) that causes a fracture or dislocation at a distant point is an indirect force. This type of force is characterized by the transmission of energy through a body part, resulting in a fracture or dislocation at a different location than the impact.

An indirect force refers to a situation where a force is applied to one part of the body, but the resulting injury occurs at a distant point from the site of impact. This can happen when the force is transmitted through bones, joints, or tissues, causing them to break or become dislocated at a different location.

For example, if a person falls and lands on an outstretched hand, the impact is absorbed by the wrist joint, but the force may be transmitted to the elbow or shoulder joint, causing a fracture or dislocation at those distant points.

In contrast, a direct blow involves a force applied directly to the site of injury, such as a punch or a kick. A twisting force involves rotational movement around an axis, which can result in fractures or dislocations. High-energy injuries refer to traumatic incidents involving significant force, such as motor vehicle accidents or falls from heights, which can cause fractures or dislocations at various points depending on the specific circumstances.
