When an object is placed just outside the focal length of a concave mirror, the image is

swat32

Answer:

O larger than the object and real

Explanation:

As we know by the formula of mirror

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

here we know that

$d_o = (f_o + x)$

so we have

$\frac{1}{d_i} = \frac{1}{f_o} - \frac{1}{f_o + x}$

so we have

$d_i = \frac{(f_o)(f_o + x)}{x}$

so magnification is given as

$M = -\frac{d_i}{d_o}$

$M = - \frac{f_o}{x}$

so here we have

$|M| > 1$

so image will be larger than object and real

You place a box weighing 253.1 N on an inclined plane that makes a 39.7◦ angle with the horizontal.

Masja [62]

Answer:

Explanation:

The weight of the box is

W = 253.1N

Weight is on an incline plane

θ = 39.7°

The weight of an object is always acting downward

So, the weight makes an angle of 39.7° with the vertical component

Then, it's horizontal component is

Wx = W•Sinθ

Wx = 253.1 × Sin 39.7°

Wx = 161.67 N

The horizontal component of the weight is 161.67N

This is the force acting down the plane.
