Avertical scale on a spring balance reads from 0 to 250 n . the scale has a length of 14.0 cm from the 0 to 250 n reading. a fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.85 hz .

The mass of the fish is 5.56 kg.

Explanation:

Given that,

Force = 250 N

Length = 14.0 cm

Frequency = 2.85 Hz

Suppose ignoring the mass of the spring, what is the mass m of the fish?

We need to calculate the spring constant

Using formula of spring constant

Where, F = force

x = length

Put the value into the formula

We need to calculate the mass of the fish

Using formula of frequency

Put the value into the formula

Hence, The mass of the fish is 5.56 kg.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

the independent variable, or the one that is intentionally manipulated is the speed.
