The relationship between mass and acceleration is an inverse proportionality
Explanation:
The relationship between the acceleration of an object and its mass is given by Newton's second law, which states that:
where
F is the net force on the object
m is its mass
a is its acceleration
From the equation, we notice that if the force on the object is kept constant, then the mass and the acceleration are inversely proportional to each other. This means that:
- If the mass of the object is increased, its acceleration will decrease
- If the mass of the object is decreased, its acceleration will increase

Answer:
Answer:
118.4 N
Explanation:
weight of chair, mg = 95 N
Push, F = 39 N
Ф = 37 ° below x axis
Let n be the normal force.
So, by using the diagram and resolve the components of Force F.
n = mg + F SinФ
n = 95 + 39 Sin 37°
n = 95 + 39 x 0.6
n = 118.4 N
Explanation:
To answer, we determine the velocity of the flea when it leaves the ground. Using the given value for distance, the velocity can be determined through the equation,
2a d = (Vf)² - (Vi)²
where a is the acceleration due to gravity, d is distance, Vf is the final velocity which is equal to zero and Vi is the initial velocity. Substituting the known values,
2(9.8 m/s²)(40cm/100cm) = (Vi)²
The value of Vi from the equation is 2.8 m/s.
The equation for determining the kinetic energy is:
KE = 0.5mv²
Substituting,
KE = 0.5(0.60 x 10^-3g)(1 kg/1000g)(2.8 m/s)²
KE = 2.352 x 10^-6 J

Answer:
6. W = 3 m g h
Explanation:
Displacement in moving from first floor to the fourth floor is 3h, and the total energy consumed in this process is (3.m.g.h) which is equal to the work done.
According to the work-energy equivalence the change in energy of a system is equal to the work done.
Here, change in potential energy:
