I would say all of them but if I had to choose one I would say the days would get shorter because if earth began to spin faster then the sun would only be out for a couple of hrs and we would mostly see night than day
Answer:
C. must not be accelerating (i e, a = 0 m/s/s)
Explanation:
- When forces acting on an object are balanced the object is said to be at equilibrium.
- Unbalanced forces causes an object to accelerate, such that if two forces acting on an object are an equal, then the object will accelerate towards the direction of the greater force.
- On the other hand, when forces acting on an object are balanced, the object will be in a state of equilibrium and will not accelerate.
- Therefore, when forces are balanced acceleration is zero and the velocity of the object will remain constant.
<u>Answer:</u>
The time taken for the ball to hit the floor as 1.02 seconds
<u>Explanation:</u>
As per the given question, the ball leaves at a speed from the table with an initial velocity of 10 m/s, we have the equation
where Vf represents the final velocity
Vi represents the initial velocity
a represents the acceleration and
t represents the time
after rearranging
= 1.022 seconds
Answer:
If the collector of the cell is covered, the voltage is higher
Explanation:
The collector of the a passive, active, or photovoltaic (PV) solar cell is the device that takes the Sun's energy by the absorption of the Sun's radiation which is then transformed into electricity and heat. The ability to absorb the Sun's energy is given by the material type and the coating of solar collector
Therefore, the device requires access to energy from Sunlight to get the energy which can be stored in a rechargeable cell and well the collector's cell is covered, access to Sunlight is denied and therefore energy is not supplied to the cells and current is not generated and there is no flow of electricity and the voltage in the circuit is lower or there is no voltage in the circuit
The statement which is wrong about the solar cell is therefore, that <em>if the collector of the cell is covered, the voltage is higher</em>
