Answer:
a). a=0.2 
b). x=10m
c). v=2
Explanation:
Force forward push = 2000N
Resistive force due water=1800N
Net force=2000N-1800N
Fn=200N
m=1000kg
t=10sec
a).

b).

c).

Answer:
Correct answer is gaseous state
Explanation:
in gaseous state , the bonding between the molecules of matter is less compared to that in other state.
Answer: A) reactants
Explanation:
Reactants are the substances that have chemical reactions when they are combined, whereas the product is what comes from the reactants’ chemical reactions.
According to Newtons third law the force of action has an equal and opposite reaction. So if the force of the bat hitting the ball is equal to 5 N, then reaction force of the ball has to be 5 N as well. So the correct answer is: the reaction force is equal to 5 N.
