Snow leopards are solitary... If you ever see a two or more snow leopards together, consider yourself extremely lucky! Fun fact: There is no term for a group of snow leopards because it is so rare to see them in a group!
Your welcome!
Answer:
1.96 J
Explanation:
From the law of conservation of energy
ΔU + ΔK = 0 where ΔU = internal energy change and ΔK = kinetic energy change. We neglect potential energy change since we are not given any information about it.
ΔU = -ΔK
ΔK = K₂ - K₁ where K₁ = initial kinetic energy and K₂ = final kinetic energy = 0 where ΔU = 0.382K₁
= 0.382mv²/2 where m = mass of spike = 0.71 kg and v = initial speed of spike = 3.8 m/s
= 0.382 × 0.71 kg × (3.8 m/s)²/2
= 1.96 J
Answer: Yes.
Explanation: Work in physics is defined as a force causing the movement—or displacement—of an object. In this case your eyes blinking, even though it was a very quick movement that didn't require much effort or energy, is still an example of your body at work.
I am not 100% sure but i would say D, since it is a smaller object than the test thus needing a shorter wavelength
Speed = distance/time
Velocity = displacement/time
Acceleration = change in velocity/time
Time is a part of all three quantities.
