The object is not accelerating
If the ice absorbed 350,000 joules in 5 minutes, then it absorbed energy
at the rate of
(350,000 joules) / (5 x 60 seconds) =<em> 1,166-2/3 watts</em> .
Surely the ice cube didn't absorb every joule delivered to the cooking chamber,
so the microwave oven's cooking power had to be significantly more than that.
Like a seesaw, it shows that the forces aren’t equal because if it was the seesaw would stay put
Answer:
The goal of physics is to understand how things work from first principles. ... Courses in physics reveal the mathematical beauty of the universe at scales ranging from subatomic to cosmological. Studying physics strengthens quantitative reasoning and problem solving skills that are valuable in areas beyond physics
Explanation:
We have,
Mass of an object is 0.5 kg
Force constant of the spring is 157 N/m
The object is released from rest when the spring is compressed 0.19 m.
(A) The force acting on the object is given by :
F = kx
(B) The force is simply given by :
F = ma
a is acceleration at that instant
