A spaceship leaves a space station and emits a flash of light that travels at a speed of 300,000 km/s. The spaceship starts out

travelling at 1/4 the speed of light, but ends up travelling at 99/100 the speed of light. What does a scientist on the space station measure the speed of the flash to be?
B. (1/4) x 300, 000 km/s

C. (1/100) x 300, 000 km/s

D. 300, 000 km/s

timama [110]

Answer:

The transfer of heat by the movement of fluid is called Convection Heat Transfer

Explanation:

Heat transfer by convection is the transfer of heat by fluid transport from one place to another, such that convection takes place when the heat that comes in contact of fluid containing body is moved to other parts of the container by the transporting fluid

Heat is transferred within a fluid medium mainly by convection (movement of heat by the transfer of fluid particles in the medium)

Convection heat transfer is a combination of conduction and advection heat transfer

How do rocks within Earth change as P waves pass? How do rocks within Earth change as P waves pass? Rocks within Earth both expa
ohaa [14]

Rocks within Earth both expand and contract as P waves pass

Explanation:

Rocks within the earth both expands and contracts as P-waves passes through them. P-waves are elastic waves.

  • Elastic waves behaves in such a way that they do not cause permanent deformation of rocks.
  • They can be said to cause elastic deformation when they travel through rocks.
  • They simply temporarily expand and contract the rock within a short period by causing the vibration of particles of the medium.
  • After a short while, the rock returns back to its original position as if nothing has happened to it.
  • These elastic waves are better called seismic waves.
  • P-waves are primary waves that can travel through any medium.

Darwin is sitting on top of a 10 m tree and decided to drop a 3 kg baseball to the ground. What is the velocity when the PE turn
Nimfa-mama [501]

The AMOUNT of energy the ball has doesn't change. It's 294 joules in Darwin's hand, and it's still 294 joules when the ball hits the ground.  It's all PE before he let's it go, and it steadily changes from PE to KE all the way down.

It BEGINS to turn into KE immediately, when Darwin lets go of the ball, and it starts to fall.

More and more PE turns into KE as the ball falls, all the way down.

When the ball hits the ground, it has no more PE left. All of its mechanical energy is then KE.

umka21 [38]

Answer:

<h2>Force due to biceps is given as</h2><h2>F = 1991.05 N</h2>

Explanation:

For balancing the force we know that

Torque due to weight hold on his hand = torque due to force applied by biceps

So here we will have

mg \times L = F \times d

so we have

18.14 \times 9.8 \times 0.56 = F \times (0.05)

F = 1991.05 N
