If the diameter of the black marble is 3.0cm, and bye using the formula for volume, what is a good approximation if it’s volume?
tia_tia [17]

Complete question is;

If the diameter of the black marble is 3.0 cm, and by using the formula for volume, what is a good approximation of its volume?

Answer:

14 cm³

Explanation:

We will assume that this black marble has the shape of a sphere from online sources.

Now, volume of a sphere is given by;

V = (4/3)πr³

We are given diameter = 3 cm

We know that radius = diameter/2

Thus; radius = 3/2 = 1.5 cm

So, volume = (4/3)π(1.5)³

Volume ≈ 14.14 cm³

A good approximation of its volume = 14 cm³

If you decrease the distance between successive crests of a wave, this changesA. The frequency.B. The wavelength.C. The speed.D.
Feliz [49]

Answer:

option E

Explanation:

The correct answer is option E

Writing the relation between wavelength and frequency

      f = \dfrac{v}{\lambda}

f is the frequency

v is the velocity of wave

λ is the wavelength

From the above expression we can clearly see that frequency is inversely proportional to wavelength.

When the distance between the two successive crest is decreased then wave length of the wave also decrease.

If wavelength of the wave decreases then frequency of the wave increase.

hence, we can say that both wavelength and the frequency changes.

A mass M tied to a light string is moving in a vertical circle. The tension in the string at the top is TT and TB at the bottom
natita [175]

Answer:

Explanation:

Tension provides centripetal force in the circular motion . In circular motion work done by force = torque x angle

torque is zero as , centripetal force passes through axis of rotation that is center.

So work done by centripetal force  = 0

So work done by tension on M = 0
