[tex]F=G\cdot\dfrac{M \cdot m}{r^{2}}[/tex]

b.

[tex]F=6.67430 \times 10^{-11} \dfrac{N \cdot m^2}{kg^2} \times \dfrac{5.97 \times 10^{24} \ kg \times 1,300 \ kg}{(6,578 \ m)^{2}}[/tex]

c.

[tex]F=6.67430 \times 10^{-11} \dfrac{N \cdot m^2}{kg^2} \times \dfrac{5.97 \times 10^{24} \ kg \times 1,300 \ kg}{(6,578 \ m)^{2}} \approx 1.144 \times 10^{13} \ N[/tex]

d. The force of gravity acting on the satellite is approximately 1.144 × 10¹³ N

Explanation:

a. The formula for finding the force of gravity, F, acting object on an object is given as follows;

[tex]F=G\cdot\dfrac{M \cdot m}{r^{2}}[/tex]

Where;

F = The force acting between the Earth and the object

G = The gravitational constant = 6.67430 × 10⁻¹¹ N·m²/kg²

M = The mass of the Earth = 5.97 × 10²⁴ kg

m = The mass of the object

r = The distance between the center of the Earth and the object

b. Finding the gravitational force, 'F', between the Earth and the scientific satellite, we have;

The given mass of the satellite, m = 1,300 kg

The distance between the center of the Earth and the center of the satellite,  r = The length of the radius of the Earth + The height of orbit of the satellite

The given height of orbit of the satellite, h = 200 km

∴ r = R + h = 6,378 km + 200 km = 6,578 m

Therefore, by plugging in the values, we get;

[tex]F=6.67430 \times 10^{-11} \dfrac{N \cdot m^2}{kg^2} \times \dfrac{5.97 \times 10^{24} \ kg \times 1,300 \ kg}{(6,578 \ m)^{2}}[/tex]

c. Solving the above equation gives;

[tex]F=6.67430 \times 10^{-11} \dfrac{N \cdot m^2}{kg^2} \times \dfrac{5.97 \times 10^{24} \ kg \times 1,300 \ kg}{(6,578 \ m)^{2}} \approx 1.144 \times 10^{13} \ N[/tex]

d. The force of gravity acting on the satellite, F ≈ 1.144 × 10¹³ Newton

Answer:

40 m

Explanation:

The area under v-t graph gives the distance travelled by the particle.

Distance = area of ΔOBC + area of ΔCDE + area of ΔEFG

[tex]=\dfrac{1}{2}\times 4\times 10+\dfrac{1}{2}\times 2\times 10+\dfrac{1}{2}\times 4\times 5\\\\=40\ m[/tex]

So, the distance travelled by the particle in the time interval t = 0 and t= 10 s is equal to 40 m.

Answer:

Consequently the statement is FALSE

Explanation:

The process of emission of electrons or photoelectric effect, was explained by Einstein, assuming that light behaves as formed by how many so-called photons and each one of them collides with an electron, therefore to start an electron the incident photon energy must be greater than the work function of the material.

            E =K + Ф

By mentioning the intensity we increase the number of photons but we do not increase their energy.

Consequently the statement is FALSE

Answer:

D

Explanation:

A material that has a high resistivity and prevents charges from moving freely... it is part of insulators...

Plastic is a  material that has a high resistivity and prevents charges from moving freely. Option D is correct.

Plastic is described as a material that comprises an organic compound with a significant molecular weight as an important element.

Insulators are often defined as materials that do not allow electricity to flow through them.

Insulators are also referred to as poor electrical conductors. Insulators include materials such as paper, glass, rubber, and plastic.

Plastic is a  material that has a high resistivity and prevents charges from moving freely.

Hence option D is correct.

Answer:

electron

Explanation:

The electron is the subatomic particle with the least mass. Therefore option A is correct.

Both protons and neutrons have significantly larger masses compared to electrons.

The mass of an electron is approximately 9.1 x 10^-31 kilograms, while the mass of a proton is about 1.67 x 10^-27 kilograms, and the mass of a neutron is also around 1.67 x 10^-27 kilograms.

It's important to note that the "atom" is not a subatomic particle but a structure composed of subatomic particles. An atom consists of a nucleus (composed of protons and neutrons) and electrons orbiting around the nucleus.

The mass of an atom depends on the number of protons, neutrons, and electrons it contains, so it can vary widely depending on the specific atom.

In summary, when comparing individual subatomic particles, the electron has the least mass.

Answer:

a region around a magnetic material or a moving electric charge within which the force of magnetism acts.

Explanation:

The definition of a magnetic field is a place in space near a magnet or an electric current where a physical field is created from a moving electric charge that creates a force on another moving electric charge. An example of a magnetic field is the Earth's magnetic field.

Answer:

Moment is an expression involving the product of a distance and physical quantityA moment is due to a force not having an equal and opposite force directly along it's line of action. ... It is defined as the product of the force (F) and the moment arm (d). The moment arm or lever arm is the perpendicular distance between the line of action of the force and the center of moments.Moments act about a point in a clockwise or anticlockwise direction.

Explanation:

Answer:

The teddy bear did not stop at the same time as the car because of inertia.

Explanation:

The teddy bear did not stop at the same time as the car because of inertia.

Inertia is a resistance of an object to change its state of motion so if an object is moving it will continue the movement until a force act on it, and vice-versa if an object is at rest it will continue in that state until a force act on it.              

Hence, when the teddy bear was in the back seat and the car suddenly stops, the teddy kept moving forward because that was the direction of motion of the car (the teddy bear was moving forward with the car). The force of the brakes acts on the car but not on the teddy bear (not directly), that is why this force does not change the state of motion of the teddy bear.                     

Therefore, the teddy bear did not stop at the same time as the car because of inertia.

I hope it helps you!

Answer:

Fundamental unit is any unit that is not dependent on other units and other units can be derived from them

Explanation:

Units such as Kilogram, Mass and Time are said to be fundamental units because they are independent.

Differences between Mass and weight;

1. Mass is the measure of the amount of matter in a body while weight is a measure of how the force of gravity acts upon that mass.

2. Mass is a scalar quantity while weight is a vector quantity

Answer:

A

Explanation:

the object's mass determines the speed of the object and its kinetic energy

Answer:

Load = 80 Newton

Explanation:

Given the following data:

Effort = 20 N

Load arm = 15 cm

Effort arm = 60 cm

Conversion:

100 cm = 1 meters

15 cm = 15/100 = 0.15 meters

60 cm = 60/100 = 0.6 meters

To calculate the load, we would use the expression;

Effort * effort arm = load * load arm

Substituting into the expression, we have;

20 * 0.6 = load * 0.15

12 = load * 0.15

Load = 12/0.15

Load = 80 Newton

Answer:

A single fixed pulley is used to lift load by changing the direction of the lifting force. Even though a single fixed pulley has no mechanical gain in that, the effort applied is greater than the load, it is preferred in use since you do not have to pull or push the pulley up and down.
