Answer:
Explanation:
Given
mass (m)= 20 kg
acceleration (a)= 10 m/s^2
Force (f)= m a
= 20 * 10
= 200 N
B, C, and D.
Solar energy is green energy, it wouldn't contribute to global warming. However some places of the world don't receive as much sunlight (the poles) and at night you don't receive as much sunlight either. Solar energy is also very expensive to farm.
<span>The answer is 6 Joules. The kinetic energy (KE) of an object is the product of half of the mass (m) of the object and the square of its velocity (v²): KE = 1/2m*v². We know that m = 0.75 kg and that v = 4 m/s. Therefore, KE = 1/2 * 0.75 kg * (4 m/s)² = 1/2 * 0.75 kg * 16 m²/s² = 6 kg*m²/s² = 6 J.</span>
<u>Answer:</u> The charge on each plates is
.
<u>Explanation:</u>
The magnitude of charge that flows through the plates is directly dependent on the capacitance and the voltage flowing through the plates.
Mathematically,

where,
Q = charge flowing = ? C
C = capacitance =
(Conversion Factor:
)
V = Voltage across the plates = 12 V
Putting values in above equation, we get:

Hence, the charge on each plates is
.
