Answer:
Photovoltaic Energy
Explanation:
There are other forms of energy that do not involve spinning of metals to generate electricity, one of many such is the Solar Photovoltaic Energy.
Photovoltaic is a form of energy in which sunlight Is directly into electricity. This type of energy is often used to power devices such as small wrist watches, rechargeable lamps, and others. They are connected together to panels that are joined together in arrays to power people or heavy power plants. Photovoltaic power plants are happening to be one of the fastest growing sources of electricity generation around the world.
Answer:
d. 6.28 kJ.
Explanation:
step by step explanation
Q=Q1+Q2
Q=mc(t1-t0) + mlv
Q=total heat generated
Q1=quantity of heat required to raise 25.0°C to 76.8°C to liquid state
Q2= quantity of heat required to convert ccl at 76.8°C to its gaseous state
M=mass of ccl4
C=specific heat capacity of ccl4(0.866j/gk)
T1=final temperature 76.8°C
T0=initial temperature 25.0 °C
LV=latent heat of vapourization (1.959 *10^2j/g)
Q=25*0.866 *(76.8-25) +25*1.959*10^2
Q=6.28kj
The correct answer is D. Electromagnetic force
Answer:
Explanation:
The self-inductance of a solenoid is defined as:
Here 
is the the permeability of free space, N is the number of turns in the solenoid, A is the cross-sectional area os the solenoid and l its length. We replace the given values to get the self-inductance:
Answer:
The final stored energy will become half.
Explanation:
We know that stored energy in the capacitor is given as
C=capacitance
V=Voltage difference
E=Energy
d=Distance between plates
A=Area
If the distance between plates get double ,say d' = 2 d
Then stored energy
Therefore the final stored energy will become half.
