The gravitational field strength = Defined as Gravitational Force per unit mass
Gravitational Field Strength =
= Gravitational Force Exerted / Mass of object exerted on
= (9.1*10⁴) / (1.1*10⁴)
= 9.1/1.1
≈ 8.27 N/kg
≈ 8.3 N/kg
Option (3) is the answer.
Answer:
.7934
Explanation:
Acceleration = change in velocity / change in time
A = 10.98 / 13.84
A = .7934
Answer:Electricity works by getting a bunch of conductor elements together and creating a flow of electron-stealing patterns through them. This flow is called a current. ... Once you can control the direction the electrons are going, you can use them to power or charge anything from a light bulb to your TV to your electric car.
Explanation:trust
A mechanical wave<span> requires an initial </span>energy<span> input. Once this initial </span>energy<span> is added, the </span>wave<span> travels through the medium until all its </span>energy is transferred<span>. In contrast, electromagnetic </span>waves<span> require no medium, but can still travel through one</span>
Answer:
the final velocity of the bus is -20 m/s.
Explanation:
Given;
initial velocity of the bus, u = 20 m/s
deceleration of the bus, -a = 8 m/s²
time of motion, t = 5 s
The final velocity of the bus is calculated as;
v = u + at
v = 20 + (-8 x 5)
v = 20 - 40
v = -20 m/s.
Therefore, the final velocity of the bus is -20 m/s.
