Answer:
10 m/s
Explanation:
= Mass of arrow = 1 kg
= Mass of apple = 2 kg
= Initial Velocity of arrow = 30 m/s
= Initial Velocity of apple = 0 m/s
= Velocity of combined mass
For elastic collision
Final velocity of apple and arrow after collision is 10 m/s
Answer:
The answer to your question is Gamma Rays.
Explanation:
I'm sorry if I get this wrong, I also have this same question. But, I believe I am right!
The work done on the spring is equal to the elastic potential energy of a spring. We look at Hooke's law, which states that the force needed to stretch a spring is proportional<span> to the displacement of the spring.
</span><span>F = -kx
W = (integral) Fdx
</span>W = (integral) -kx dx
W = kΔx²/2
20 = k(42 - 30) / 2
k = 10/3
Answer:
Explanation:
Given:
Solute Diffusion rate = 4.0 × 10⁻¹¹ kg/s
Area of cross-section = 0.50 cm²
Length of channel =0.25 cm
Now for the new channel
Area of cross-section = 0.30 cm²
Length of channel =0.10 cm
let the Solute Diffusion rate of new channel = s
now equating the diffusion rate per unit volume for both the channels
thus,
Kinetic energy stored into a brown bear so it would be 15,000
