Answer:D
Explanation:
Given
Same force is applied to each ball such that all have different masses
and Force is given by the product of mass and acceleration
So acceleration of ball A
acceleration of ball B
acceleration of ball C
acceleration of ball D
It is clear that acceleration of ball D is least.
The answer is approximately 2.998e+8
Answer:
distance = 6.1022 x10^16[m]
Explanation:
To solve this problem we must use the formula of the average speed which relates distance to time, so we have
v = distance / time
where:
v = velocity = 3 x 10^8 [m/s]
distance = x [meters]
time = 6.45 [light years]
Now we have to convert from light-years to seconds in order to get the distance in meters.
Now using the formula:
distance = v * time
distance = (3*10^8)*203407200
distance = 6.1022 x10^16[m]
The type of radioactive decay that has a positive charge is alpha particles, which are positively charged.
<h3>What is radioactive decay?</h3>
The expression radioactive decay makes reference to the emission of ionizing radiation for a given atom, thereby an unstable atom may lose energy by releasing radiation.
Alpha particles are specific atomic particles consisting of 2 protons (positive charge) and also 2 neutrons that share chemical bonds.
In conclusion, the type of radioactive decay that has a positive charge is alpha particles, which are positively charged.

Answer:
Decrease occur in kinetic energy.
Explanation:
The kinetic energy decreases when the the Bob swings reaches to the maximum height because the motion of the bob slower down. At maximum height, the kinetic energy decreases whereas the value of potential energy is the highest. The main reason of higher potential energy is that it depends on height of an object while on the other hand, kinetic energy depends on the motion of an object so that's why the value of kinetic energy decreases and potential energy increases at maximum height of the bob.
