Answer:
The coefficient of linear expansion \°C
Explanation:
Given initial temperature °C
And final temperature °C
Initial length
Final length
We have to find the coefficient of linear expansion
The coefficient of linear expansion is defined as the change in length per unit original length divide by the change in temperature.
So, \°C
The speed of the toy when it hits the ground is 2.97 m/s.
The given parameters;
- mass of the toy, m = 0.1 kg
- the maximum height reached by the, h = 0.45 m
The speed of the toy before it hits the ground will be maximum. Apply the principle of conservation of mechanical energy to determine the maximum speed of the toy.
P.E = K.E
Substitute the given values and solve the speed;
Thus, the speed of the toy when it hits the ground is 2.97 m/s.

Answer:
W = V Q energy = work / charge * charge
Q = I t charge = current * time
V = W / (I * t)
V = 3 * 10E8 J / (1.5 * 10E4 amps * 2 * 10E-4 sec)
V = 10^8 volts
Answer:
true
Explanation:
for example assume you are setting in a moving bus and when someone see you from the ground you are in motion but for some who is with you in the bus you are not in motion.
