Newton's 2nd law of motion: Force = (mass) x (acceleration)
Divide each side by (mass) : Acceleration = (force) / (mass)
Acceleration of the truck = (4,200 N) / (2,000 kg) = 2.1 m/s²
Answer: C
Explanation: Density= mass/volume
if dividing by same volume, need to increase mass in order to increase density.
same as 4=8/2 vs 8=16/2
increase numerator= increase in answer
Answer:
The mass of the banana is m and it is at height h.
Applying the Law of Conservation of Energy
Total Energy before fall = Total Energy after fall
= 
Here, total energy is the sum of kinetic energy and potential energy
+ 
= 
+ 
(a)
When banana is at height h, it has
= 0 and = mgh
and when it reaches the river, it has
= 1/2m
and = 0
Putting the values in equation (a)
0 + mgh = 1/2m + 0
mgh = 1/2m
<em>cutting 'm' from both sides</em>
<em> </em>gh = 1/2
v = 
Hence, the velocity of banana before hitting the water is
v =
Answer:
Because the planet is far away from the sun
Explanation:
The closer the planet is to the Sun, the greater the pull of the Sun's gravity, and the faster the planet orbits.
While, over here the Pluto is very far away from the Sun so it will have very little gravitational pull and still keeps revolving around the Sun

Photosynthesis is the process by which plants convert/change LE ==> CE. ========> ||
(Light Energy ==> Chemical Energy) <=v
Q. What is the chemical reaction involved?
A. The conversion of water and carbon dioxide combine to form glucose and oxygen.
The chlorophyll is the location of these chemical reactions.
Photosynthesis is a endothermic chemical reaction.
Q. Why is photosynthesis considered to be a endothermic reaction?
A. Plants store energy through endothermic reactions and then are released by exothermic reactions called Respiration.
I hope that helps you!! Any more questions??
