Answer:
Newton (N)
Explanation:
Newtons are used to measure force.
Answer:
The value speed is
Explanation:
From the question we are told that
The mass of the ping pong ball is
The radius is
The depth of the ping pong inside the water is
Gnerally the force with which the ball will emerge will from the water is mathematically represented as
Here B is the Buoyant force on the ball which is mathematically represented as
Here is the volume of the ball which is mathematically represented as
=>
=>
is the density of water with value
So
=>
So
=>
=>
Generally force is mathematically represented as
So
=>
Generally from kinematic equation
Here u is the velocity of the ping pong at depth of 0.3 m and the value is zero given that at that point there was no motion
So
=>
Explanation:
gravity is the force that acts between all objects
Answer:
The answer is below
Explanation:
The equation for a linear line graph is given by:
y = mx + b, where y and x are variables, m is the slope of the graph and b is the y intercept (that is value of y when x is zero).
The slope (m) of a line passing through two points is given by:
A) The first line passes through the point (0, 0) and (10, 60). It is represented as (time, velocity). Hence the slope is:
B) The second line passes through the point (10, 60) and (15, 60). Hence the slope is:
C) The third line passes through the point (15, 60) and (40, -40). Hence the slope is:
D) The third line passes through the point (40, -40) and (55, 0). Hence the slope is:
