Answer:
F
Explanation:
Newton's Third Law (Law of Action-Reaction) states:
Every action has an equal and opposite reaction and it occurs between two objects
In this scenario, the action would be the skater pushing off of the wall, therefore the reaction would be the wall pushing off of the skater since the two objects that are interacting are the wall and the skater.
Answer:
a) 096V b) 0.0288A c) 0.3456W
Explanation:
a) Vp/Vs= Np/Ns
120/Vs= 500/4
Vs= 096V
b) Np/Ns= Is/Ip
500/4= 3.6/Ip
Ip= 0.0288A
c) P= VI
P=(120)(0.0288)
P= 0.3456W
Answer:3.67 s
Explanation:
Given
Ball is thrown with an initial velocity of 
As the ball moves upward it experience a declaration due to gravity which will slow down the ball
using

where v=final velocity
u=initial velocity
a=acceleration
t=time
Here 



Answer:
Resistance can increase relative to Temperature, Nature of Material, Length of Conductor or wire.,and Cross-section area.
Explanation:
The mass of the first block will be three times the mass of the second block.
According to Newton's second law of motion, the force acting on a body is directly proportional to the acceleration as shown;


F is the acting force
m is the mass
a is the acceleration of the body
Given the following parameters
Constant force F = 1N
For the first block with the acceleration of "a"
1 = m₁a
a = m₁/1
m₁ = a .................1
For the second block, acceleration is thrice that of the first. This means;
F = m(3a)
1 = 3ma
..........................2
Divide both equations

From the calculation, we can conclude that the mass of the first block will be three times the mass of the second block.
