By measuring the potential energy of an object relative to the ground, and the object's mass, you can calculate its speed when i

t hits the ground. Explain why you can do this.
A.because gravitational potential energy can convert to elastic potential energy
B.because gravitational potential energy can convert to kinetic energy
C.because the gravitational potential energy can convert to sound energy
D.because gravitational potential energy can convert to electric potential energy

Answer:

B.because gravitational potential energy can convert to kinetic energy

Explanation:

You can calculate the speed as it hits the ground because gravitational potential energy can convert to kinetic energy.

In this way, total energy can be conserved.

  • We can equate the kinetic energy and potential energy.
  • From this we can solve for the velocity.
  • This way, we know that the potential energy is changing to kinetic energy.

Answer:

0 m

Explanation:

Displacement is the shortest distance from one ppont to another. Here, the girl returns to the same spot after running. Hence, displacement is <u>0</u><u> </u><u>m</u>.

How much work does this force do as the particle moves along the x-axis from x = 0 to x = l? express your answer in terms of the
nydimaria [60]
<h3><u>Answer</u>;</h3>

= F0 L ( 1 - 1/e )

<h3><u>Explanation;</u></h3>

Work done is given as the product of force and distance.

In this case;

Work done  = ∫︎ F(x) dx  

                    = F0 ∫︎ e^(-x/L) dx  

                    = F0 [ -L e^(-x/L) ] between 0 and L  

                    = F0 L ( 1 - 1/e )

Calculate the weight of a new fast-food sandwich that has a mass of 0.1 kg (approximately the mass of a quarter pound). Think of
iragen [17]

Weight = (mass) x (gravity)

If you plan to sell these things on Earth, then the acceleration of gravity in the neighborhood of your drive-throughs will be 9.81 m/s².

Weight of each sandwich = (0.1 kg) x (9.81 m/s²).

Weight of each sandwich = 0.981 Newton.

This is only  1.9%  less than 1 even Newton.

You should start by setting up one restaurant in New York, one in Chicago, one in LA, and maybe one in Miami or Tulsa.  Sell it with a different name in each place, and see which name sells best.

You might want to try calling it

-- Isaac's burger

-- Gravity grub

-- Prism Patty

-- Mass 'o Meat

-- Unit-wich

and see if anything catches on.

I think I'd simply call it a "Newton Unit".
