If size of two balls are same and they are dropped from same height
Then the net force on two balls are given as
here we know that
= weight of the ball
= viscous or drag force of medium
now by Newton's II law we can find the acceleration of ball
now if we ignore the medium resistance as it is very small
so both the balls will have same acceleration
and also by kinematics we can say
so here we can see that since two balls are dropped from same height and the acceleration is also same for both so here it will take same time to reach the ground.
We have that for the Question,it can be said that the field has a <u>value </u>of
From the question we are told
a small object with a charge of magnitude q creates an electric field. at a point 1.0 m to the north of the charge the field has a value of 2.0 n/c directed south. at a <em>point </em>0.5 m to the west of the <em>charge </em>the field has a value of
<h3> Electric
field </h3>
Generally the equation for the <em>electric</em> field is mathematically given as

It would be a physical change because the properties of the red food colouring would not actually affect the chemical properties of the bleach.
Rebuilding whatever it is, putting a covering on it that naturally repels water like rubber.
Answer:
<em>The mass of the shotput is 7.37 Kg.</em>
Explanation:
<u>Mechanical Force</u>
According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:
F = m.a
Where a is the acceleration of the object. If the net force is zero, the object keeps moving at the same speed or keeps at rest (v=0).
A force of 140 N is exerted by a shot-putter on a shotput, which gets an acceleration of 19 m/s^2. We are required to calculate the mass of the shotput.
It can be done by solving the equation for m:
Substituting the given values:
m = 7.37 Kg
The mass of the shotput is 7.37 Kg.
