Electric force is present between proton and electron of an atom.
What is the attractive force present between a proton and electron?The attractive force between the electrons and the proton of the nucleus is called the electric force. This force attract electron towards the nucleus so that it can't escape from the atom easily so this force is very important for the atom.
How an atom of this element changes when it forms an ionic bond?An atom of this element changes when it forms an ionic bond because the number of electron decreases due to losing of electron in order to get stability. We know that ionic bond forms between atoms when electron is lost or gain by the atom.
So we can conclude that electric force is present between proton and electron of an atom.

The magnitude of their final momentum immediately after the collision is 51 Kgm/s and their direction immediately after the collision will be in the direction of the second skateboarder.
What is Momentum ?Momentum is the product of mass and velocity. Momentum can also be the product of force and time.
Given that two skateboarders collide and grab onto one another. If the first skateboarder has a momentum of 525 kg • m/s, and the second skateboarder had a momentum of -576 kg•m/s immediately before they collide, that means their collision was head - on - collision.
According to the conservation of linear momentum, the magnitude of the sum their final momentum immediately after the collision will be the same with the sum of the magnitude of their momentum before collision. That is,
Final momentum = 525 - 576
Final momentum = - 51kg•m/s
And their direction immediately after the collision will be in the direction of the second skateboarder.
Therefore, the magnitude of their final momentum immediately after the collision is 51 Kgm/s and their direction immediately after the collision will be in the direction of the second skateboarder.

(b) Is a skateboard coasting down a hill at 2 m/s experiencing acceleration? Explain why or why not.
(c) Is a car stopping at an intersection experiencing acceleration? Explain why or why not.
The If a car is going round a curve , there is an acceleration because the direction of the velocity changes.
What is the direction of the velocity?Now we know that if you throw the ball upwards, the motion is in opposite direction to gravity thus the ball is experiencing deceleration and the speed decreases. The velocity decreases and the acceleration is negative.
If the ball is coming down, then the ball is accelerated thus it speeds up and the direction of the acceleration is positive.

For a 1 efficient step down transformer voltage in primary and secondary are equal current in primary and secondary are equal input power is same as the output power output power is zero
The given condition for a 100% efficient step down transformer is not true.
How do Step-down Transformers work?Because there are fewer turns in the secondary winding of a step-down transformer, the secondary voltage is lower than the initial voltage. As a result, this kind of transformer is employed to reduce the voltage to the levels intended for the circuit. Almost all power supply incorporate a step-down transformer to keep the operating voltage range of the circuit within acceptable limits. Electronic transformers and distribution systems are often where these transformers are installed (power transformers).
What Does a Step-Down Transformer Mean by Power?Using the system voltage and current, we can calculate the power of a transformer. Volt-Amps, or VA, is the unit used to measure the power in a transformer (for larger transformers Kilo Volt-Amps, kVA).
Any transformer should, in theory, have constant power on both sides, which implies that the power available on the secondary side of the transformer should match the power available on the primary side. This also applies to step-down transformers. A step-down transformer's secondary side has a lower voltage than its primary side, hence in order to balance the transformer's total power, the secondary current would need to be increased.
What is the Step-Down Transformer's Relationship Between Voltage and Current?In a step-down transformer, the output current is greater than the input current while the output voltage is lower than the primary voltage.

Explanation:
Let [tex]u[/tex] and [tex]v[/tex] denote the velocity of this hockey player before and after stopping, respectively. The question states that [tex]u = 9.5\; {\rm m\cdot s^{-1}}[/tex] and implies that [tex]v = 0\; {\rm m\cdot s^{-1}[/tex] since the hockey player has come to a stop.
