Answer:
This is the answer: The speed of a proton is about 5.0 × 10⁵ m/s
Explanation:
Because of the speeds of protons! :D
Answer:

Explanation:
We use the kinematics equation to solve this question:

because the ball is dropped
the acceleration is the gravity, negative because it points downwards
initial height
final height
So:


Change of a liquid to a gas
It would either break or stop depends on the density
To solve this problem it is necessary to apply the concepts related to the Power defined from the Stefan-Boltzmann equations.
The power can be determined as:

Making the relationship for two states we have to

Since the final power is 8 times the initial power then

Substituting,



The temperature increase would then be subject to



The correct option is D, about 68%
