<u>Answer</u>
Gravitational force
<u>Explanation</u>
Gravitational force is the force of attraction between two bodies of a given masses. It is calculated as follows:
Gravitational force = GM₁M₂/r²
From the formula it can be seen that gravitational force is inversely proportional to the r where are is the distance between the two bodies.
When the distance increases the gravitational force decreases.
Answer:
The distance, d = 230 m
Explanation:
The distance is a scalar quantity and it is defined as how much ground an object covered to move from initial location to the final location.
It doesn't depend on which direction the object traveled.
The distance is always positive and non-zero.
Unlike the displacement, which is only depended upon the initial and final position of the coordinate without considering the path traveled, distance depends on the path of travel.
Given,
The cyclist traveled south, S = 80 m
The cyclist traveled west, W = 150 m
The total distance traveled, d = S + W
= 80 + 150
= 230 m
Hence, the total distance traveled by the cyclist, d = 230 m
Answer:
100,048
Explanation:
K.E = 1/2 m (v)^2
K.E = 1^/2 * 74 * (52)^2
K.E = 100,048J =100.048kJ
Answer:
towards right so it is -15 degree
Explanation:
Net force in forward direction due to all three is given as
here we know that
Similarly in Y direction we will have
Now the net force on the donkey is given as
Now direction of force is given as
towards right so it is -15 degree
Answer:
final velocity = 9.6157 m/sec
Explanation:
To solve this question, we will use one of the equations of motion which is:
v^2 = u^2 + 2as
where:
v is the final velocity that we want to get
u is the initial velocity = 3.75 m/sec
a is the acceleration due to gravity = 9.8 m/sec^2
s is the distance = 4 m
Substitute with the givens in the equation to get the final velocity as follows:
v^2 = u^2 + 2as
v^2 = (3.75)^2 + 2(9.8)(4)
v^2 = 92.4625
v = 9.6157 m/sec
Hope this helps :)
