You do work on something when you lift it against gravity. How does this work relate to gravitational potential energy? If the l

ifted object is released, what becomes of this energy? Be sure to define all terms that you use.

Answer:

Increase in the gravitational potential energy will be equal to the work done by us to raise its height.

If the lifted block is released then this gravitational potential energy will convert into kinetic energy of the block.

Explanation:

As we know that work done done to raise the block against the gravity is given as

W = F.d

here force to raise the block will be

F = mg

now if it is raised to height "h" then work done is given as

W = mgh

so the potential energy stored in the block will be

U = mgh

now when this is released from this height then the potential energy will convert to Kinetic energy of the block as it will drop by the given height.

so we have

KE = U = mgh

<span>Lifting an object increases the gravitational potential energy of the system. If you release the object, that potential energy will be transformed into the energy of an object in motion which is termed as the kinetic energy as it falls toward earth. Hope this helps.</span>

Kevin has a mass of 87 kg and is skating with in-line skates. He sees his 22-kg younger brother up ahead standing on the sidewal
neonofarm [45]

Answer:

V_ k = 3 m/s  

Explanation:

Using the conservation of the linear momentum P:

P_i = P_f

so:

M_kV_k = M_sV_s

where M_k is the mass of kevin, V_k is the velocity of kevin before he grabs her brother, M_s is the velocity of her brother and him after grabs her brother and V_s is the velocity of both after the collition.

So, replacing the values and solving for Vk, we get:

(87 kg)V_k = (87 kg+22 kg)(2.4m/s)

V_ k = 3 m/s

Ohm's law relates the current, voltage, and resistance in a circuit. Use Ohm's law to determine what will happen to the remainin
krek1111 [17]

Answer:

   R = ½ R₀

Explanation:

This is an exercise in Ohm's law,

           V = IR

in the initial case

           V₀ = I₀ R₀               (1)

indicates that the voltage remains constant and the current is doubled

             I = 2 I₀

           V₀ = I R

             

we substitute

           V₀ = 2 I₀ R

            R = ½ V₀ / I₀

we replace by equation 1

            R = ½ R₀

Please help! I'd really appreciate it :-)
Alexxx [7]

Answer:

0.31429 Amps

Explanation:

Using the "Ohm's Law" we can look for the current (amps) with a formula of I = V/R

Given:

Resistance (Ohm) = 350

Volts = 110

Solution:

I = 110v/350r

I = 0.31429 amps
