Answer:
Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. ... Forces that cause a change in the motion of an object are unbalanced forces.
Answer:
2.83m
Explanation:
The information that we have is
Intensity at 2.0 m: 
and 
we need an intensity level of: 
thus, we are looking for the distance 
.
which we can find with the law for intensity and distance:
we solve for :
and we substitute the known values:
at a distance of 2.83m the intensity level is 40dB

First bacterial cells are usually much smaller than plant or animal cells. a human skin cells , for example is about times as larger as an average bacterial cell.
Answer:
Gravitational force, F = 1054.65 N
Explanation:
Given,
The accelerating speed, a = 15 m/s²
The mass of your body, m = 155 lbs
= 70.31 Kg
The gravitational force acting in a body is given by the relation
F = m x g
Where g is the acceleration due to gravity of the in which the velocity of the body changes its speed at a constant rate.
∴ a = g
Substituting the values in the above equation
F = 70.31 x 15
= 1054.65 N
Hence, the gravitational force acting on you, F = 1054.65 N
