Answer:
bo sure but I think its c or a
A. Horizontal component: 7.3 m/s
Explanation:
The horizontal component of the velocity is given by:

where
is the magnitude of the initial velocity
is the angle of the initial velocity with respect to the ground
Substituting numbers into the equation, we find

B. Vertical component: 14.3 m/s
Explanation:
The vertical component of the velocity is given by:

where
is the magnitude of the initial velocity
is the angle of the initial velocity with respect to the ground
Substituting numbers into the equation, we find

The power delivered is equal to the product between the voltage V and the current I:

This power is delivered for a total time of

, so the total energy delivered to the battery is
Answer:
Option C.
Explanation:
<u>Natural uranium is composed by 99.27% of U-238, 0.72% of U-235 and 0.005% of U-234</u>.
Of the isotopes of natural uranium, the U-235 is the most commonly utilized in nuclear power plants, but since it is only 0.72% of natural uranium it needs to be enriched before being used as fuel to sustain a nuclear fission reaction in nuclear power plants.
<u>The U-238 is the most common and the heaviest of the three naturally occurring isotopes of uranium</u>.
So, from the above the correct option is the C.
Have a nice day!
