I’m pretty sure that it’s true. Hope this helps
Explanation:
Mass of the car = 2000N / 10 = 200kg.
Fnet = ma. Assuming there is only the horizontal force acting on the car, then
F = (200kg)(3.3m/s²) = 660N.
I think answer is A. The Brightness of a Star
Velocity = displacement / time
v = 400 / 2
v = 200 km/h
Now, = 200 / 3.6 = 55.55 m/s
In short, Your Answer would be 55.55 m/s
Hope this helps!
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.
