Because of friction and air resistance, every moving object will eventually come to rest unless a continuous net force is applied to it.
<h3>What is friction?</h3>
Friction is the opposition offered to motion of a body over another body.
Friction can either be:
- Solid friction as in friction in solids
- Fluid friction as in air resistance
The law of inertia states that an object will remain in its state of rest or state of motion in a straight line unless acted upon by an external force.
However, due to friction and air resistance, every moving object will eventually come to rest unless a continuous net force is applied to it.
In conclusion, moving objects come to rest because of friction and air resistance.

Answer:
F = 10 [N]
Explanation:
To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
F = forces [N]
m = mass = 0.05 [kg]
a = acceleration = 200 [m/s²]
Acceleration = v-u/t
= (45-30)/15
= 1 km/h
Distance = ut + 1/2 at^2
s = [30 x 15] + 1/2 x 1 x 15^2
= 562.5 km

Answer: the position of the 1st minima of diffraction = position of the fifth maximum of double slit
finding the ratio
a/d
λ×L/a = 5×λ×L/d
a/d = 0.2
Explanation:
when the light passes through the double slit in such a way that the interference fringes appear ion the wide maxima pattern of diffraction light.If the interference maxima fringe overlaps on the 1st minima of diffraction interference will disappear.
Answer:
Explanation:
d = rt only works for calculating average speeds.
100 = r(140)
r = 0.714 m/s
