Which statement is true about an object moving in a circular motion due to centripetal force, F, when the mass is doubled?

Ans) A) Centripetal force will be doubled.

See centripetal force F = mv^2/r

That means centripetal force is directly proportional to the mass of the particle

So, if we double the mass, centripetal force will be increased by twofolds.

So, option A) is correct.

Now, looking at the other options,

B) says centripetal force is unaltered which is incorrect as centripetal force has been altered and increased twofold.

Option C) and D) reduces centripetal force which are also not possible here.

So, only Option A) is correct

A body is moving along a circular path with variable speed, it has both radial and tangential acceleration.
belka [17]

Answer:

True;   ar = v^2 / R      Radial acceleration because it moves in a circular path

    at = α R = tangential acceleration because its speed changes

a = at + ar    total acceleration equals sum of radial and tangential

Large electric fields in cell membranes cause ions to move through the cell wall. The field strength in a typical membrane is 1.
serg [7]

Explanation:

The given data is as follows.

          Electric field (E) = 1 \times 10^{7} N/C

          Charge (e) = 1.6 \times 10^{-19} C

Formula to calculate the magnitude of force is as follows.

                F = qE

                   = 1.6 \times 10^{-19} \times 1 \times 10^{7} N/C

                   = 1.6 \times 10^{-12} N

Therefore, we can conclude that magnitude of the force on a calcium ion with charge +e is  1.6 \times 10^{-12} N.

What is the best description of the destructive interference of light?
Lelechka [254]

Answer:

B. Two waves have displaced in opposite directions

Explanation:

Interference occurs when two waves meet at a point in space. When this occurs, two extreme conditions can occur:

- if the two waves are in phase (=displacement in the same direction), the amplitude of the resultant wave is equal to the sum of the amplitudes of the two waves:

A = A1 + A2

and this condition is called constructive interference

- if the two waves are in anti-phase (=displacement in opposite directions), the amplitude of the resultant wave is equal to the difference of the amplitudes of the two waves:

A = |A1 - A2|

and this condition is called destructive interference. Note that if A1=A2, the amplitude of the resultant wave is zero.
