Answer:b
Explanation: If you look at the line on the graph, you can see that it is going downward, meaning it has a negative slope, and choice b is the only one that has a negative slope
Answer: friction has no role to play in this case. because friction usually occurs between to parts which come in contacts. examples (a)our joints in the human body (b)two mechanical parts (shafts).
Explanation:
However what this topic relates to is gravity. The pebble and paper both weigh one gram, but have different density this is the sole reason why if both are drop from same height the pebble would reach the ground faster than the paper because it is more denser. unlike the paper with a lesser density which would take a longer time to reach the ground.
Answer:
962291.57928 m²
Explanation:
= Pressure = 
(full reflection)
I = Intensity = 
P = Power = 
c = Speed of light = 
M = Mass of Sun = 
m = Mass of ship = 1500 kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
Force of radiation is given by
This force will balance the gravitational force as stated in the question
The area of the must be 962291.57928 m²
Answer:
Since strong nuclear forces involve only nuclear particles (not electrons, bonds, etc) items 3 and 4 are eliminated.
Again item 2 refers to bonds between atoms and is eliminated.
This leaves only item 1.
Nuclear forces are very short range forces between components of the nucleus.
Weak nuclear forces are trillions of times smaller than strong forces.
Gravitational forces are much much smaller than the weak nuclear force.
