W=FdeltaD (Work is equal to Force multiplied by displacement.
F=W/delta D
F=2J/8m
F=0.25N
No. Beta particles are electrons.
Answer:
In one rotation, the large wheel turns 4m.
Explanation:
The given values are:
Input distance,
= 0.64 m
Mechanical advantage,
= 0.16
As we know,
⇒
On putting the values, we get
⇒
⇒
d.88 n
Explanation:
The force exerted by gravity on the mass is 88N;
Gravitational force is usually experienced by two bodies with masses.
This force causes all objects on earth to accelerate at 9.8m/s².
Force of gravity = mass x acceleration due to gravity
In this case, the force exerted on the object by gravity will be the weight of the object.
Weight is a force applied gravity on a body:
Weight of the masses = Force of gravity = mass x acceleration
Given mass = 9kg
Force of gravity = 9 x 9.8 = 88.2N approximately 88N
