1. Find the spring constant k:
F = mg = kx
68 * g = k * 0.0055m
k = 121287.273
2.Find the frequency f:
ω = 2πf = √k/m
f = √(k / m)/ 2π = 1.7
The force between two parallel wires carrying currents in the same direction is attractive. It is repulsive if the currents are in opposite directions.
No, the car travels 1 metre in 5s at the start which is 0.2m/s, while the second meter it travels one metre in 8 seconds which is 0.125 m/s, the speed changes therefore it is not constant during the two metres the car travels
This is False . Flowering plants are angiosperms.
