A far-sighted person has a near-point of 80 cm. To correct their vision so that they can see objects that are as close as 10 cm

bekas [8.4K]

Answer:

$f = 8.89 cm$

Explanation:

As we know that Far sighted person has near point shifted to 80 cm distance

so he is able to see the object 80 cm

now the distance of lens from eye is 2 cm

and the person want to see the objects at distance 10 cm

so here the image distance from lens is 80 cm and the object distance from lens is 8 cm

now from lens formula we have

$\frac{1}{d_i} + \frac{1}{d_0} = \frac{1}{f}$

$-\frac{1}{80} + \frac{1}{8} = \frac{1}{f}$

$f = 8.89 cm$

If the net force acting on a stationary object is zero then the object will

Drupady [299]

If the net force is zero, then there is no acceleration, which means no change in velocity. The velocity starts at zero, so it must remain at zero. Therefore, the object will not move.

A 7kg bowling ball is at rest at the end of a bowling lane. You push the ball with a force of 22N which induces a -1N of frictio

Valentin [98]

Explanation:

You can find the net force by summing the force components:

∑F = 22 N − 1 N

∑F = 21 N

Or by using Newton's second law:

∑F = ma

∑F = (7 kg) (3 m/s²)

∑F = 21 N
