Answer:
(a) S = 1.8m
(b) F = 23.9N
Explanation:
The solution to this problem requires the knowledge of the concepts of constant acceleration motion for part (a) and newton's second law for part(b).
(a) s =(u + v)/2 ×t
(b) F = m(v-u)/t
u = 0m/s because the pitcher starts to throw the ball from rest

Answer:
correct answer is Stationary
Explanation:
solution
the correct answer is Stationary because when 2 mass of air is pushing each other opposite direction but there is no power to move other mass of air than their stationary front is form as a cold front or the warm front stop moving
and the wind blowing parallel to the front instead of perpendicular that can help it stay in a place
so correct answer is Stationary
Hello!
In chemistry, atomic mass is normally written in amu. This stands for atomic mass units.
Within an atom, there are three main parts: protons, neutrons, and electrons. Between these three, electrons are extremely light. However, protons and neutrons both weigh 1 amu.
Thus, this means to get the atomic mass, add together the protons + neutrons.
Hope this helps!
<u>Answer:</u> The correct answer is 2.24 MeV.
<u>Explanation:</u>
The chemical reaction for the formation of deuterium from proton and neutron follows:
We are given:
Mass of 
= 1.00784 u
Mass of 
= 1.008665 u
Mass of 
= 2.014102 u
To calculate the mass defect, we use the equation:
To calculate the energy released, we use the equation:
(Conversion factor: 
)
Hence, the energy released in the given nuclear reaction is 2.24 MeV.
