Answer:
<h2>
GRAVITY</h2>
Explanation:
When an object is dropped in the air , it experiences free fall.
Free fall is a special type of motion in which the only force acting upon an object is gravity. They do not encounter a significant force of air resistance
Answer:
10.8s
Explanation:
Given parameters:
Force on the car = 3250N
Distance = 35m
Power = 11375W
Unknown:
Time taken = ?
Solution:
To solve this problem;
Power is the rate at which work is done
Power =
Work done = force x distance = 3250 x 35 = 123200J
Now;
11375 =
11375t = 123200
t = 10.8s
Answer:
The answer is -x direction.
Explanation:
According to the right hand rule for electromagnetism, when the thumb points up, index finger points forward and the middle finger is perpendicular to the index finger, the thumb points in the direction of the magnetic force, the index finger in the direction of the charge movement and the middle finger in the direction of the electromagnetic lines. If the electric field is pointing in the -z direction which is into the screen and the magnetic field is in the +y direction which is upwards, then the magnetic lines are in the -x direction.
I hope this answer helps.
The force that a moving object has which is dependent on the speed and weight of the object is Momentum
The product of an object's mass and velocity is known as its linear momentum, translational momentum, or simply momentum in Newtonian physics. It has both a magnitude and a direction, making it a vector quantity. When an object has a mass of m and a speed of v, its momentum, p, is equal to ma. Its SI Unit is Kgm/s
The speed of a body is defined as the rate at which the position of a body changes per unit of time. Its SI unit is m/s.
Weight is defined as the amount of force, in general, it's the gravitational force, which acts on the body. It is measured in Kilogram (kg).
