Answer:
Force = 150 Newton.
Explanation:
Given the following data;
Mass = 60kg
Acceleration = 2.5m/s²
To find the force;
Force = mass * acceleration
Force = 60 * 2.5
Force = 150 Newton.
Therefore, the force required to accelerate this mass is 150 Newton.
The law of conservation of energy is that energy cannot be broken or made up
Answer:
d = 114.95 m
Explanation:
Givens:
a = 7.6 m/s^2
t = 5.5 s
v_i = 0 m/s
a = (v_f-v_i)/t
7.6 m/s^2 = (v_f-0 m/s)/5.5 s
v_f = (7.6 m/s^2)*(5.5 s)
v_f = 41.8 m/s
d = [(v_f+v_i)/2]*t
d = [(41.8 m/s)/2]*5.5 s
d = 114.95 m
D. The chemical potential energy of real battery decreases, it develops internal resistance and therefore the potential difference across its terminals decreases if its current increases.
Answer: A
Explanation: A paper clip is a conductor (metal) which completes the electrical circuit. Rubber and paper are not conductors..
