Answer:
Bob provided the greatest impulse.
Explanation:
Given:
Arnold exerts force = 300 N for 3 seconds
Bob exerts force = 500 N for 2 seconds
Cecil exerts force = 200 N for 4 seconds.
Find:
Highest impulse
Computation:
Impulse = Force × TIme
Arnold provides impulse = 300 N × 3 seconds = 900 N/s
Bob provides impulse = 500 N × 2 seconds = 1,000 N/s
Cecil provides impulse = 200 N × 4 seconds = 800 N/s
Therefore, Bob provided the greatest impulse.

Answer:
D. agrarian
Explanation:
The agrarian society is a society that is strictly revolving around the agriculture and animal farming for its survival. In this type of society, the people are only engaged in producing food, be it by planting and raising certain crops or breeding domesticated animals. The main purpose of this type of society is to be able to produce enough food for the whole year, so it is a self maintaining society that consumes as much as it produces. The situation described about Ken is a reflection of this type of society.
The state of the atmosphere at a given place and time as regards to heat, dryness sunshine, wind, rain, etc.
Answer:
Static friction, F=2.9988 N
Explanation:
Static Friction: It is the friction between two or more solid body that are not moving relative to each other.
When an external force is applied to a body that is in contact with another body, static friction opposes the applied force upto a certain limit, keeping the body at rest. When the applied force exceeds the certain limit the body begins to move. At that moment applied force is equal to limiting value of static friction F.
It varies linearly with normal force(N)
F∝N
F=μN (where μ is constant of proportionality and known as coefficient of static friction)
Now,
Mass, m=1.53 kg
Coefficient of static friction, μ=0.2
Normal force, N=m×g
=
(g=9.8 m/s²)
=14.994 N
Static friction, F= μN
=
= 2.9988 N
