If you attach a 100 g mass to the spring whose data are shown in the graph, what will be the period of its oscillations?
ycow [4]

if for a force of 0.5 N we have a displacement of -0.02m we can calculate the elastic constant(k) with the formula F=-kx(F=0.5N x=-0.02)

k=F/x k=0.5/0.02=25N/m

now we can calculate the period by the formula

T=2π√(m/k)

in the mass we convert grams to kilograms so 100g=0.1kg

T=6.28√(0.1/25)⇒T=0.39seconds

An object is propelled along a straight-line path by a force. If the net force were doubled, the object's acceleration would be_
nikdorinn [45]

Answer:

double

Explanation:

According to the newton's second law

force = mass x acceleration

So, acceleration is directly proportional to the force.

As the force is doubles, the acceleration is also doubled.
