7 0

Answer:

v = 83.3 m/s  = 300 kph

Explanation:

PE + W = KE

mgh + 255000 = ½mv²

2(9.8)(250m) + 2(255000) / 250 kg = v²

v = 83.3 m/s

What are two advantages of using renewable resources?
Pavel [41]
One advantage is that whatever resource it is, it will never run out and you wont have to worry about not having it. A second is that there is going to be enough for everyone to use however much they want without there having to be a limit on how much you use.

If you lift the front wheel of a poorly maintained bicycle off the ground and then start it spinning at 0.69 rev/s , friction in
Sindrei [870]

Answer:

magnitude of the frictional torque is 0.11 Nm

Explanation:

Moment of inertia I = 0.33 kg⋅m2

Initial angular velocity w° = 0.69 rev/s = 2 x 3.142 x 0.69 = 4.34 rad/s

Final angular velocity w = 0 (since it stops)

Time t = 13 secs

Using w = w° + §t

Where § is angular acceleration

O = 4.34 + 13§

§ = -4.34/13 = -0.33 rad/s2

The negative sign implies it's a negative acceleration.

Frictional torque that brought it to rest must be equal to the original torque.

Torqu = I x §

T = 0.33 x 0.33 = 0.11 Nm

Which of these would best describe the outcome of increasing the kinetic energy of the molecules in the above picture?
Lyrx [107]

A) The temperature will increase.

Kinetic energy is the intrinsic energy carried by an object in motion.

Explanation:

Increasing the kinetic energy of the molecules means that molecules rapidly. This causes an increased rate of collision between the molecules and between the molecules and the walls of the container. Most of these collisions are inelastic meaning that some of the energy in the collisions is lost as heat energy to the environment. This means the system becomes hotter.

Why do intrusive igneous rocks have large crystals?
Aleksandr-060686 [28]
The magma cools very slowly so that the crystals of different minerals have time to grow. The magma molecules in have time to organize themselves into crystal formations before the magma hardens. The naked eye helps the Intrusive rocks that has large crystals be seen.

you see an insect egg lying on a leaf. What is the next step? Name or describe the stage you would expect to see come out from t
Marianna [84]

Answer:

Metamorphosis are the series of processes involved in the development of organisms, mostly insects after the egg is hatched.

Insects undergo complete or incomplete metamorphosis

Complete metamorphosis involves 4 stages which is the development from egg to larva to pups to adults in a step wise manner e.g butterfly, moth etc

Egg—> Larva—> Pupa—> Adults

In incomplete metamorphosis the stages are 3 and it involves development from egg to nymph to adults. E.g cockroach

Egg—> Nymph—> Adults
