Answer:
Momentum = 750 Kgm/s
Explanation:
Given the following data;
Mass = 10 kg
Velocity = 75 m/s
To find the momentum;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Substituting into the formula, we have;
Momentum = 10 * 75
Momentum = 750 Kgm/s
Answer:
<h2>900 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question is we have
force = 75 × 12
We have the final answer as
<h3>900 N</h3>

d = M/V, where d is density, M is mass, and V is volume, is the formula for density. Grams per cubic centimeter are a typical unit of measurement for density.
To fill the graduated cylinder to the 2.0 mL mark, add water. The water makes a curve if you see the graduated cylinder from the side. Make sure the 2.0 mL level is at the bottom of the curve. Calculate the graduated cylinder's mass and the water's mass in milliliters using the gram scale. In the table, note the mass. Subtract the graduated cylinder's mass to determine the mass of 2.0 mL of water. To find and note the mass of 4.0 mL of water, repeat this procedure.

According to law of reflection, the barber should place one mirror in front of the chair and two mirrors on the left and right sides of the chair perpendicular to the front mirror. According to law of shadows, the bulb should be placed above the chair.
What is the law of refraction?
The angle of incidence is equal to the angle of reflection.
- According to the law of reflection, when two mirrors are placed parallel to each other, then infinite images are formed. So if the bulb is placed between two parallel mirrors, then there will be more light.
- By using the front mirror and the side mirrors, the person can see his hair from all sides.
What is the law of shadow?
The length of the shadow of an opaque substance on the surface decreases as the angle between the blocked light ray and the surface plane increases.
- According to the law of shadows, when the light falls on an opaque substance perpendicularly, then no shadows are formed. So hairs will be easily visible to the barber.
- So the light should be placed above the chair.
