The approximate change in gravitational force from Earth as a result of the change in radius of the satellite's orbit is 5. 35N
What is the universal law of gravitation?The universal law of gravitation states that the particle of matter in the universe attracts another particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
It is written thus;
F = G MIM2÷ r∧2
Where
F = Gravitational force
G = Gravitational constant
M1 and M2 are the masses of the object
r = radius
How to calculate the gravitational forceFormula:
F = G MIM2 ÷ r∧2
Given M1 = 150kg, M2 = 5.97 x 1024 kg, r = 7.5 x 106 m, G = 6.67 x 10-11 N-m²/kg²
For the first orbit, substitute the values
F = 6.67 x 10∧-11 × 150 × 5.97 x 10∧24 ÷ (7.5 x 10∧6)²
F = 5.95 × 10∧16 ÷ 56.25 × 10∧12 = 105.77 N
For the second orbit of radius 7.7 x 106 m
F = 6.67 x 10∧-11 × 150 × 5.97 x 10∧24 ÷ (7.7 x 10∧6)²
F = 5.95 × 10∧16 ÷ 59.25 × 10∧12 = 100. 42 N
The approximate change = 105. 77 - 100.42 = 5. 35N
Hence, the approximate change in gravitational force from Earth as a result of the change in radius of the satellite's orbit is 5. 35N

19,976 = 8.8 x massmass = 19,976/8.8mass = 2270 kgIf a constant force of 917 N is exerted on a scooter for 6 s, thenwhat is the change in momentum?
a 6 kg-m/s
b 5502 kg-m/s
c 917 kg-m/s
d 153 kg-m/s
Answer: 917
Explanation:
The change in momentum if a constant force of 917 N is exerted on a scooter for 6s is 5502kg-m/s.
How to calculate momentum?Momentum is the tendency of a body to maintain its inertial motion. It is the product of its mass and velocity, or the vector sum of the products of its masses and velocities.
Force = mass x (velocity/time)
Force = (mass x velocity)/time
Force = momentum/time
According to this question, a constant force of 917 N is exerted on a scooter for 6s. The change in momentum is calculated as follows:
917N = p/6
p = 5502kg-m/s
Therefore, 5502kg-m/s is the change in momentum of the scooter.

car accelerates from rest at 4.5 m/s² for 3 seconds.
a. What is the car's velocity after 3 seconds?
b. What distance does the car travel in the 3 seconds?
m/s
A car accelerates from rest at 4.5 m/s² for 3 seconds, the car's velocity after 3 seconds is 13. 5 m/s
The distance the car travel in the 3 seconds is 40. 5m/s
The first equation of motion is v = u + a t. It explains the relationship between velocity and time.
V = Final velocity
u = Initial velocity
a = acceleration
t = time.
How to determine the velocity
When an object is brought to rest or moves from resting, U, initially velocity equals 0.
From the formula,
V = u + at
V = ?
u = 0, because the object was at rest.
a = 4. 5 m/ s²
t = 3 seconds
Velocity, V = 0 + 4. 5 × 3
Velocity , V = 0 + 13. 5
Velocity, V = 13.5 m/s²
How to determine the distance
Velocity = Distance ÷ time
Velocity, V = 13. 5 m/s²
time = 3 seconds
distance = ?
Distance = Velocity × time
Distance = 13. 5 × 3
Distance = 40. 5 m
Therefore, the car's velocity after 3 seconds is 13. 5 m/s² and the distance the car travels after 3 seconds is 40. 5m

Answer:
It has a central nucleus composed of 29 protons and 35 neutrons, surrounded by an electron cloud containing 29 electrons
Explanation:
Atoms Composition:
A atom is mainly composed of a centrally-placed nucleus. A nucleus consists of protons and neutrons with a cloud of electrons surrounding the outside. A proton is a nuclear particle having a positive charge equal to that of an electron and a mass more than 1800 times the electron. A neutron is a nuclear particle having a mass almost identical to that of an electron, but no electric charge.Calculation:

Q32.4 Sometimes neon signs located near a powerful radio station are seen to glow faintly at night, even though they are not turned on. What is happening?
Neon lamps located near a powerful radio station are seen to glow faintly at night because radio waves may generate a potential difference in the neon gas.
What is a neon lamp?A neon lamp is a lamp containing neon gas as well as other types of gases and two electrodes.
In a neon lamp, the electricity is generated by striping negative electrons from neon atoms, which ionize these atoms.
The radio waves can also ionize atoms in the neon lamp by generating a potential difference in the neon particles of the lamp, thereby glowing faintly at night.
In conclusion, neon signs located near a powerful radio station are seen to glow faintly at night because radio waves may generate a potential difference in the neon gas.

mu = 0.3 . Through frictionless pulley and strings of negligible mass, a small mass P, 400g, is at rest on a 200g weighting pan.
Draw a free body diagram representing the situation, and use it to determine the acceleration of the system. Use the value of acceleration calculated to determine the relative weight of P in pounds.
(a) The acceleration of the system is determined as 1.58 m/s².
(b) The relative weight of P is pounds is determined as 0.14 lb.
Acceleration of the system
The acceleration of the system is calculated as follows;
