andrew11 [14]

Answer:

1 m                              

Explanation:

Given

The mirror is a concave mirror.

Radius of curvature = 2 m

Now, for a parallel beam after reflection  occurs, the object should be placed at the focus of the mirror.

We know, focal length = radius of curvature / 2

                                      = 2 / 2

                                      = 1

Thus the focal length is 1 m.

Hence the object should be placed at 1 m from the concave mirror for parallel beam reflection.

(20 points) Pressure is a measure of force per unit area or P=F/A. A student is checking the amount of pressure their car exerts
Gala2k [10]

Answer:

35.2 ps

Explanation:

Hello!

A US short ton is equal to 2 000 pounds, therefore:

2.25 tons = 4500 pounds

Now lets convert the area of each tire footprint:

1 cm = 0.393701 in

12.5 cm = 4.92126 in

16.5 cm = 6.49607 in

Therefore, the area of the footprint is:   31.9688 in^2

Then, the pressure exerted by the car is given by the weigth devided by the total area, that is 4 times the area of the footprint :

4500 /(4 * 31.9688)  psi = 35.1906 psi

Rounding to the first tenth

35.2 psi
