On mars people would way less. 
An example of this is that if I weighed 700 pounds (I don't by the way) I would then weigh 500 pounds or less.

Answer:  On Mars, a person will weigh <u>less</u> than on Earth.

Explanation:

The mass of the planet Mars is less than Earth. Because of this it pulls the objects on it with less force and thus Mars has less value of acceleration due to gravity.

The weight of the object is given by the product of mass and acceleration due to gravity.

W = m g'

W ∝ g'

The mass remains constant irrespective of the planet but weight varies with the value of acceleration due to gravity. Thus, on Mars, a person will weigh less than on Earth.

g During a collision with a wall, the velocity of a 0.4 KgKg ball changes from 25 m/sm/s towards the vall to 12 m/sm/s away from
bogdanovich [222]

Answer:

F = 10.8N

Explanation:

Given the mass m = 0.4kg, v1 = 25m/s, v2 = 12m/s and t =0.5s

From Newtown's second law of motion the average force can be found. This law states that the product of the force experienced by a body and the time t of the force acting on the body is equal to the change in momentum of the body. Mathematically it can be stated as follows

F×t = m(v2 – v1)

F = m(v2 – v1)/t = 0.4(25 – 12)/0.5 = 10.8N

Each molecule of iron oxide is made up of how many iron stone
Anastaziya [24]
<span>The cosmetics industry uses the compound to create various pigments in make-up as well. Most oxide forms are non-toxic, water repellent, and do not run or bleed, making them an ideal additive to products like mascara, liquid and powder foundation, and eye shadow. Oxides can also be found in certain types of health products such as talcum powder, facial cream, and body cream. Some sunblock products contain it as well. Its structure is often thought to help block the sun’s harmful ultraviolet rays from damaging human skin.</span>

A 1200 kg truck accelerates from 25 m/s to 53 m/s over a distance of 350 m.
sveticcg [70]

Answer:

the average net force on the truck is 3744 N.

Explanation:

Given;

mass of the truck, m = 1200 kg

initial velocity of the truck, u = 25 m/s

final velocity of the truck, v = 53 m/s

distance traveled by the truck, d = 350 m

The acceleration of the truck is calculated as;

v² = u² + 2ad

53² = 25² + (2 x 350)a

700a = 53² - 25²

700a = 2184

a = 2184 / 700

a = 3.12 m/s²

The average net force on the truck is calculated as;

F = ma

F = 1200 x 3.12

F = 3744 N

Therefore, the average net force on the truck is 3744 N.
