A. 800 because it has to be an equal for acting against it to remain stationary.
Given:-
Force , F = 150 N
Area on which force act ,A = 0.5m²
To Find:-
Pressure ,P
Solution:-
Pressure = Force/Area
•P = F/A
Substitute the value we get
→ P = 150/0.5
→ P = 150×10/5
→ P = 1500/5
→ P = 300 Pa.
Therefore, the pressure acting on the object is 300 Pascal.
Additional Information!!
• Product of mass and acceleration is called force.
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀OR
• Push or pull of an object is called force.
• SI unit of Force is Newton.
• It is denoted by N.
• Force is vector Quantity i.e., both Magnitude and direction.
• Mathematical term
• Force = Mass×Acceleration
Answer:
In marginal analysis, when comparing costs and benefits, an optimal choice is found when MB≥MC
Explanation:
As per marginal analysis, optimal decision-making involves taking actions when the marginal benefit exceeds the marginal cost. (i.e. MB>=MC)
Marginal cost can be defined as the change in the Total cost when producing an additional unit of output.
so the answer is (a) MB≥MC
I would say b.) because it is stating how no matter what, kids will soon become adults even when there is heart breaks, wounds, and lost friendships
