<span>The only thing that can change the motion of an object is a net (unbalanced)</span>force acting on it. This is given by Newton's First Law of Motion, sometimes <span>also called the Law of Inertia.

A PUC test would be the most likely course of action for a chemist. It is the most effective method for figuring out how the components of gasoline impact the kinds of pollutants.
<h3>What is air pollution?</h3>
The vapors created by gasoline evaporation and the chemicals produced by gasoline combustion cause impurity in the air known as air pollution.
When gasoline is burned, it emits carbon dioxide, a greenhouse gas.
Hence, the chemist's most likely action would be to do a PUC test.
To learn more about the air pollution refer to:

Answer:
16 cm
Explanation:
For protons:
Energy, E = 300 keV
radius of orbit, r1 = 16 cm
the relation for the energy and velocity is given by
So, .... (1)
Now,
Substitute the value of v from equation (1), we get
Let the radius of the alpha particle is r2.
For proton
So, ... (2)
Where, m1 is the mass of proton, q1 is the charge of proton
For alpha particle
So, ... (3)
Where, m2 is the mass of alpha particle, q2 is the charge of alpha particle
Divide equation (2) by equation (3), we get
q1 = q
q2 = 2q
m1 = m
m2 = 4m
By substituting the values
So, r2 = r1 = 16 cm
Thus, the radius of the alpha particle is 16 cm.
The work that you do on the lever will be the same as the work done by the lever on the rock. This aligns with the Law of the Conservation of Energy which states that energy can not be created nor destroyed. Since work can be calculated as force applied over a distance, you will apply a smaller force but your distance will be longer. The lever will apply a greater force over a shorter distance in proportion to yours. Therefore, the same amount of work is done on both sides of the lever.
Answer:
ω = 380π rad/s
Explanation:
The formula for the angular frequency is the oscillation frequency f (hertz) multiplied by 2π
ω = 2πf
then
ω = 2π(190)
ω = 380π rad/s
