The addition of antifreeze to
water in a car radiator causes the freezing point of the mixture to increase. The
answer is letter A. It protects the car radiator from freezing due to cold
temperatures. It is added below the freezing point of water to prevent it from
solidifying.
Displacement is the straight-line distance and direction from start-point to end-point, regardless of the actual path taken.
In this example, that's 10.3 km (rounded) in the direction 14 degrees west of South.
we know the equation for the period of oscillation in SHM is as follows:
T = 2 * pi * sqrt(mass/k)
we know f = 1/T, so f = 1/(2 * pi) * sqrt(k/m).
since d = v*T, we can say v = d/t = d * f
the final equation, after combining everything, is as follows:
v = d/(2 * pi) * sqrt(k/m)
by plugging everything in
v = .75/(2 * pi) * sqrt((1 * 10^5)/(30))
We find our velocity to be:
v = 6.89 m/s
