Surface waves are caused when P and S waves come to the surface.
Answer:
Weight = 3891.6 N
Explanation: Given that a body has half of the mass and the radius of the earth, that is,
Mass M = 1/2 × 5.972 × 10^24 kg
Where 5.972 × 10^24 kg is the mass of the earth.
M = mass of the body
M = 2.986 × 10^24 kg
r = 1/2 × 6400 m
Where 6400 kilometre is the radius of the earth and r is the radius of the body.
r = 3200 km
To find the weight, let us first find the gravitational strength of the object by using the formula
g = GM/r^2
Where G = 6.67408 × 10-11 m3kg-1 s-2
g = (6.67408 × 10^-11 × 5.972 × 10^24 ) ÷ (3200 ×1000) ^2
g = 3.985 × 10^14/1.024 × 10^13
g = 38.9 m/s^2
Formula for weight = mg
Where m = 100kg
Weight = 100 × 38.9
Weight = 3891.6 N
Answer:
a) If the mass get double then the potential of the spring gets four times.
b) P'=3.848 J
Explanation:
Given that
P= 0.962 J
m = 3.5 kg
m'= 7 kg
Lets take extension in the spring is x when the mass 3.5 kg is attached to the spring.
m g = K x
K=Spring constant
We know that potential energy given as
If the mass get double then the potential of the spring gets four times.
P'= 4 P
When mass ,m' = 7 kg
Then potential will be
-----1
-------2
From equation 1 and 2
P'= 4 x 0.962 J
P'=3.848 J
Answer:
Newton's Third Law of Motion
Explanation:
Newton's Third Law of Motion which states that, for every action there is an equal but opposite reaction.
This ultimately implies that, in every interaction, there is a pair of forces acting on the two interacting objects.
In this scenario, a ball bounced by a basketball player on the floor bounces back up at her.
According to Newton's Third Law of Motion, the statement above simply means that in every interaction, there is a pair of forces acting on the two interacting objects i.e the ball and floor. The size of the force on the ball equals the size of the force on the floor. These two forces are called action and reaction forces and are the subject of Newton's third law of motion.
Hence, the ball bounced by the basketball player on the floor would bounce back in equal magnitude.
Answer:
