Answer:
Explanation:
Given
mass of chair m=21 kg
Force required to set chair in motion is 175 N
Once the chair is in motion 137 N is require to move it with constant velocity
i.e. 175 N is the amount of force needed to just overcome static friction and 137 is the kinetic friction force
thus
where 
is the coefficient of static friction and N is Normal reaction
Answer:
Force has a direct relationship to mass and acceleration. Newton's Second Law, force equals mass times acceleration (F=MA), illustrates their general relationship in an equation.
Explanation:
Relationships to remember:
- <u>Force</u> and <u>acceleration</u> have a direct relationship, meaning if force increases, acceleration will also increase and vice versa
(Ex: The harder you push a box, the faster it will move)
- <u>Mass</u> and <u>acceleration</u> have an inverse relationship, meaning if mass increases, acceleration will <em>decrease</em> and vice versa
(Ex: If you add more furniture in the back of a moving company truck, the truck will move slower than it did before the furniture was added)
- <u>Force</u> and <u>mass</u> have a direct relationship, meaning if mass increases, force will also increase
(Ex: You will need to exert less force to lift a 5-pound weight than a 10-pound weight)
And of course, Newton's Second Law, F=MA sums all of this up in 3 letters and a symbol! If you have any more questions about this problem, please comment on my answer :)
Answer:
24 kgm/s
Explanation:
Momentum (p) = mass x velocity
Mass = 3kg , velocity 8m/s
momentum (p) = 3kg x 8m/s
= 24kgm/s
Answer:
Hey mate here's your answer ⤵️
Since pressure depends only on the force acting perpendicular to the surface upon which it is applied, only the force component perpendicular to the surface contributes to the pressure exerted by that force on that surface.

Voltage is increased, i think.
