Explanation:
Given that,
Initial length of simple pendulum,
Initial time period,
We need to find the length of the simple pendulum when the period is exactly 1 second.
We know that the time period of simple pendulum is given by :
Put all values and find L₂
So, the length of the pendulum with a period of exactly one second is 25 cm.
Gravitational attraction / field strength increases when closer; A light dependent resistor (LDR) can be used as a sensor to detect light intensity.
Answer: The energy to move the fluid is provided by the pressure on the fluid surface.
Explanation: The frictional losses in the suction pipework and rises in the suction pipework system will reduce the fluid pressure at the pump inlet. If the pump inlet connection is removed the fluid will not flow out of the suction pipework. Hope this helps! :)
The answer is A because all the others are wrong
