Answer:
0.47 J
Explanation:
The elastic potential energy of a spring is given as,
E = 1/2ke²........................ Equation 1
Where E = Elastic potential energy, k = spring constant, e = extension/compression.
Given: k = 15 N/m, e = 0.25 m.
Substitute into equation 1.
E = 1/2(15)(0.25)²
E = 0.46875
E ≈ 0.47 J.
Hence the elastic potential energy stored in the spring = 0.47 J
Answer:
the answer is A: voluntary reflexes
Explanation:
because Alcohol poisoning can effect the brain which voluntary is something in the brain
Answer: A
Explanation: Neglecting air resistance every object will return to the ground at the same interval regardless of their weights, we can say that the objects are undergoing free falls, they are falling under the sole of gravity.
No matter the weight of the objects or the elevation, without significant air resistance, they will reach the ground at the same time.
Answer:
Because the surface tension of the water does not allow the sound waves in the air to pass through.
