As the temperature increases the kinetic energy of the molecules increases, if u add more heat you get more kinetic energy.
Answer:
true,true,false
Explanation:
its false because if it is equal it would show an arrow pointing left and a 20 and the same for the right
By applying Newton's second law of motion;
ma = mg - T
Where,
m = mass; a = downward accelerations (+ve value) or upward acceleration (-ve value); g = gravitational acceleration; T = tension.
For the current case, the velocity is constant therefore,
a = 0
Then,
0 = mg - T
T = mg = 115*9.81 = 1128.15 N
Tension in the cable is 1128.15 N.
Answer:
Explanation:
momentum = mv
m = 8 kg
v = 12 m/s
momentum = 8 * 12 = 96 kg m/s
