A 20-kg cart travels at 20 m/s in a circle with a radius of 20 m. What is the centripetal force?

Answer:

The equation for centripetal force is:

T = (mv^2)/r

T = centripetal force

m = mass

v = speed

r = radius

T = [20kg * (20 m/s * 20m/s)] / 20 m

T = [20kg * 400 m/s^2] / 20 m

T = 8,000 kg m/s^2 / 20 m

T = 400 N

Centripetal force = (mass) x (speed)² / (radius)

                           = (20 kg) x (20 m/s)² / (20 m)

                           = (20 x 20 / 20)  (kg-meter/sec²)

                           = 20 newtons

What can increase the gravitational potential energy of a object
love history [14]

Answer:

Increase in mass and height

Explanation:

The gravitational potential energy of an object can increase if the mass and height of object is increased.

Gravitational potential energy is the energy due to the position of a body.

It is expressed as:

  Gravitational potential energy = mass x acceleration due gravity x height

Increasing mass and height will cause an increase in gravitational potential energy.

Is it possible for an object to be going 100 miles per hour but have a velocity of zero?
Lesechka [4]
It is possible for on object to be going at 100 miles per hour, but still have a velocity. This is because the object going at 100 miles per hour has speed, which is a scalar quantity, which is defined by only magnitude, but the velocity of the object can be 0, since velocity is a vector quantity which is defined by both magnitude and direction.

Since this object only has magnitude and no direction (which is not given), then the velocity can be 0

zalisa [80]

Option B i.e discretion is the right and correct answer.

[C]utting programs that were not effective or essential and even some that were, but are now unaffordable; and precisely targeting our investments. Every department will feel the impact of these reductions as they cut programs or tighten their belts to free up more resources for areas critical to economic growth. —President Barack Obama, 2012 Budget Message of the President.

The President above clearly refers to the Discretion Spending where portion of the budget is decided by Congress through the annual appropriations.
