terry physics pushes a 75kg lab cart so that is accelerates from rest with a velocity of 4.4m/s in 3.1 secounds. what is the for
svetlana [45]

106.5N

Explanation:

Given parameters:

Mass of cart = 75kg

Velocity = 4.4m/s

time taken = 3.1s

Unknown:

Force = ?

Solution:

To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".

      F = m  x   a

F = force on body

m = mass of body

a = acceleration of the body

 But we know that acceleration is the change in velocity with time of a body;

     a  = \frac{change in velocity }{time}

  F = m x \frac{V}{t}

V is the velocity

t is the time taken

   F = \frac{75  x  4.4}{3.1}   = 106.5N

Select the correct statement about chemical energy, a term used by biologists to refer to potential energy available for release
vekshin1

Answer:

A photosynthetic cell within a plant leaf produces chemical energy, stored within glucose molecules.

Explanation:

The energy captured from sunlight by Photosystems in chlorophyll is used to split a water molecule and reduce carbon dioxide to carbohydrates. This energy from sunlight is therefore stored in the chemical bonds of the glucose molecules. It is thereafter harnessed during cellular respiration when the chemical bonds of glucose are broken and the energy transferred to make ATP molecules.

Which best blocks X-ray particles and can therefore be observed more closely through the use of this technology?
Vedmedyk [2.9K]

Answer:

The correct answer would be bones.

X-rays are high energy electromagnetic waves which have an ability to penetrate most of the biological tissues.

In the X-ray machine, a beam of high energy X-rays is passed through the filters and subject and then fall on the detector or photographic film to produce X-ray.

Dense tissues like bone, teeth, tumors et cetera blocks or stops most of the X-ray particles from reaching the detector or photographic film.

It forms glowing pictures on the X-ray film or photographic film.

The denser the material the brighter the image will be formed on the photographic film.

How does soil affect the surface of the earth
Blizzard [7]

The type of soil varies from place to place on our planet and can even vary from one place to another in your own backyard. Soil erosion, caused by wind and rain, can change land by wearing down mountains, creating valleys, making rivers appear and disappear.
