Answer:

P = -1.67 dP

Explanation:

given,

myopic lawyer has a far point of = 60.0 cm = 0.6 m

If a person is suffering from myopia then he cannot see the farthest object clearly.

Image of far object does not form on the retina so, the image appear to be blur.

using lens formula

      \dfrac{1}{v}-\dfrac{1}{u} = \dfrac{1}{f}

                -\dfrac{1}{0.6} = \dfrac{1}{f}

                     \dfrac{1}{f} =P

                              P = -\dfrac{1}{0.6}

                              P = -1.67 dP

At which latitudes do currents of dry sinking air cause the dry conditions of earth's major deserts
Inessa05 [86]
Currents of dry sinking air cause the dry conditions of earth's major deserts at: <span>30° N and 30° S Latitudes

At approximately 30 degrees from the equator, the air that moved up from the equator started to descends. This air, however, could only come from one direction. So when the air is blocked by a mountain, the other side will not receive any water that it contains. This makes the other sides of the mountain became really dry which will eventually cause the formation of the desert.</span>

(a) The acceleration of the salt shaker is 1.18 m/s².

(b) The distance traveled by the baseball player before coming to rest is 204.1 m.

<h3>Acceleration of the salt shaker</h3>

The acceleration of the salt shaker at the given coefficient of kinetic friction is determined as follows;

a = μg

a = 0.12 x 9.8

a = 1.18 m/s²

Acceleration of the baseball player is calculated as follows;

a = μg

a = 0.4 x 9.8

a = 3.92 m/s²

<h3>Distance traveled by the baseball player</h3>

The distance traveled by the baseball player before coming to rest is calculated as follows;

v² = u² - 2as

0 = 40² - 2(3.92)s

0 = 1600 - 7.84s

7.84s = 1600

s = 204.1 m

The complete question is below:

A baseball player slides into third base with an initial speed of 40 m/s. If the coefficient of kinetic friction between the player and the ground is 0.40, how far does the player slide before coming to rest?
