For the given problem, we calculate the required time by
using the formula P = W/t.
P = [(1/2)mv_f^2 – (1/2)mv_i^2]/ t
The car accelerates from 0 -58 mph, so the power engine will
be
P = (1/2) x m x 58^2 / t = 1682 m / t
According to the problem, the engine produces full power so
the time required can be calculated as
420.5 m / 1.40 = 1682 m / t
t = 5.6 seconds
Explanation:
Let the 2 be X and Y.
Z is 3rd angle.
Z=2X
w.k.t Sum of angles in a triangle is 180°
Z+X+Y=180°
2X+90°=180°
2X=90°
=>X=45°
=>Y=90°-45°=45°
=>Z=2X=2(45°)=90°
Hope this helps you.
Answer:
it takes 3 hours to travel

120 ÷ 40 = 3
Answer:
is the current through the body of the man.
energy dissipated.
Explanation:
Given:
- time for which the current lasted,
- potential difference between the feet,
- resistance between the feet,
<u>Now, from the Ohm's law we have:</u>
is the current through the body of the man.
<u>Energy dissipated in the body:</u>
why was my answer taken off? There is no way to show evidence for this but ig I can explain. The electrical energy is what is used to power the radio so it works, then the energy is used to catch radio waves which makes sound energy. So the answer is C, electrical energy to sound energy
