Answer:
The centripetal force acting on the car is proportional to the mass of the car.
Explanation:
Let,
The mass of the car be 'm'
The velocity of the car moving in the curved path be 'v'
The radius of the curved path be 'r'
According to physics, a body moving ion circular path experience a force directed along the radius of the path. This force is called centripetal force.
The formula for centripetal force is,
<em>F = mv²/r</em>
Where,
a = v²/r
So, if the mass of the car changes, the centripetal force also changes proportionally according to the above equation.
Answer:
3. Kinetic energy of the system is maximum when potential energy is minimum.
Explanation:
Given that
Mass of block= m
Spring constant =K
Table is friction less.
As we know that in oscillatory motion ,when kinetic energy is maximum then potential energy will become minimum.
At the mean position:
Kinetic energy is maximum.
Potential energy is minimum.
At the extreme position:
Kinetic energy is minimum.
Potential energy is maximum.
At the mean position velocity of block will be maximum that is why it have maximum kinetic energy and at the extreme position the velocity of block will be minimum that is why it have minimum kinetic energy.
So from above we can say that kinetic energy of the system is maximum when potential energy is minimum.
A) all because of the movement, and friction involved with the movement.
Answer:
Explanation:
Length of the conveyor belt is given as
time taken to cook one burger is given as
now we can find the speed of the belt as
Now we know that the distance between two burgers is given as 25 cm
now the production rate of burgers is given as
