Elena-2011 [213]3 years ago
4 0

Answer:

m = image distance/object distance

m=35/15=7/3

f=uv/(u+v)

35*15/(35+15)

f=10.5cm

Q15.17 Both wave intensity and gravitation obey inverse-square laws. Do they do so for the same reason?Discuss the reason for ea
s2008m [1.1K]

(a) Intensity obeys inverse square law from basis of light passing through a given surface.

(b) Gravitation obeys inverse square law from the basis of force between two masses.

(c) The maximum magnitude of the acceleration of the block is 126.75 m/s².

<h3>What is intensity?</h3>

Intensity is the ratio is ratio of power to area of a given surface.

I = P/A (W/m²)

where;

  • P is power
  • A is area
<h3>Universal gravitation law</h3>

F = \frac{Gm_1m_2}{r^2}

Intensity and gravitation do not obey inverse square law for same reason;

  • Intensity obeys inverse square law from basis of light passing through a given surface.
  • Gravitation obeys inverse square law from the basis of force between two masses.
<h3>Acceleration of the block</h3>

a = v²/A

a = (3.9²)/0.12

a = 126.75 m/s²

Which statements describe how a machine can help make work easier? Select two options.
ad-work [718]

Answer:

  • It can put out more force than the input force by decreasing the distance through which force is applied.
  • It can apply a force to an object in a different direction than the force applied to the machine.

Explanation:

Assuming the machine is a simple machine, such as a lever or pulley, the machine will not do any more work than is put into it. However, it can change the magnitude or direction (or both) of the input force required to achieve a particular output force.

Because the machine does not increase the work done, if the output force is greater, the output distance must be less.

The applicable observations are ...

  • It can put out more force than the input force by decreasing the distance through which force is applied.
  • It can apply a force to an object in a different direction than the force applied to the machine.
