The correct option is (D). i.e.<span>When the current is too high, a metal strip in the fuse melts and opens the circuit.
Explanation: </span>The fuse contains a small piece of wire which has very less melting point. As there is huge current flow, the wire heats to the heavy current flow & melts & the circuit is broken.
Hence, it saves the device from the heavy current flow & the device is damage free. breaks the circuit if a fault in an appliance causes too much current flow.
Answer: The tidal forces exerted by the moon are directly associated with the earth's rotation. Due to the strong gravitational pull of the moon, the tidal bulging appears on both the sides on earth and these are region of high tide, and there is gradual rise and fall of sea level.
Because of these tidal effect, the earth is able to rotate only once in each of the orbital period.
Force is (mass × acceleration) measured in Newton
Pressure is the 'force' per unit area measured in Newton/m^2 (pascal)
It depends on what speed you are going at. Assuming you are in our fastest spacecraft as of now which has a speed of 17,500 mph
1 light second = 186,282 mph
There are <span>31,536,000 in one year so 17,500x=31,534,000 and your answer would be in years. It would take you roughly 1802 years.</span>
(Sorry about mph I'm American.)
