Answer:
Option D
4200 W
Explanation:
Power, P is also given as the product of voltage and current, expressed as P=VI
Here, P is power, V is voltage in the xircuit and I is current theough voltage.
Taking 12 V for voltage across and 350A for current across circuit then power will be
P=350*12=4200 W
Therefore, option D is correct.
The Speed In Kilometers per year is 63.072.
The energy associated with an object's motion is called kinetic energy. ... This is also called thermal energy – the greater the thermal energy, the greater the kinetic energy of atomic motion, and vice versa.
The velocity of penguin as he ends where he started was 0 m/s.
<h3>What is displacement?</h3>
Displacement is the length of straight line joining the initial and final position of the body.
Given is a penguin who waddled 8 m uphill before sliding back down to its friends in 2 seconds.
We know that the velocity is the rate of change of displacement with respect to time. Mathematically -
v = dx/dt
dx = v dt
∫dx = ∫v dt
Δx = vΔt
v = Δx/Δt
Now, the displacement of the penguin will be = Δx = 8 - 8 = 0
Then, its velocity will be -
v = 0/Δt = 0
Therefore, the velocity of penguin as he ends where he started was 0 m/s.
