Answer:
The answer to your question is: D.
Explanation:
Distance refers to the amount of space between two points, it is a scalar quantity.
Displacement refers to the space between two points, measure from the minimum path linking them, it is a vector quantity.
I'm not agree with these answers, because the total distance is approximately 500km.
A) The distance traveled is 300 km. This answer is not correct.
B) Distance is 300 km and displacement is 0 km. This answer is not correct because the displacement is also 500 km.
C) Distance is 300 km/hour and displacement is 300 km.
300 km/h is a measure of speed not of distance, this option is wrong.
D) Both distance traveled and displacement are 300 km. I think this is the correct answer because distance and displacement measure the same. but I think both measure 500 km.
Kinetic Energy = 1/2mv^2
m= 1200kg
v= 24 m/s
KE = 1/2 (1200kg)(24m/s)^2 = 345,600 N
The nucleus is the core of an atom which is made up of protons and neutrons. Every single type of atom has a dense center and the majority of the mass is located in here.
No chande in mass becouse of the change in gravitational force do not effect in mass
Answer:
a) Impulse(J)=40.04 kg.m/s
b)F=2566.66 N
Explanation:
Given that
We know that impulse(J) impulse is a vector quantity
We know that P=mV
So
Now by putting the values
J=1.3(9.8-(-21))
So impulse(J)=40.04 kg.m/s
Force is given as
or we can say that
So 
F=2566.66 N
