Answer:

B.) the universe may continue to expand

Explanation:

The steady state theory which states that the universe was, is and will be the same, has been discredited by two physicists who found the leftover energy from the big bang.

If you are listening to FM radio, you might have heard some static noise while changing stations, that noise is from the leftover energy from the big bang. This energy is called the dark energy.

The dark energy tries to rip everything apart while gravity tries to hold everything together.

It was observed that the dark energy is stronger than gravity.

The distance between the galaxies is increasing. This proves that the dark energy successfully defeated the gravity and expanted two massive objects in the universe.

Because of this dark energy the universe will continue to expand.

Note: Dark energy is also increasing the distance between protons in atomic nucleus in every atom in our body too. Chilly right?

A roller coaster starts from rest at point A. What is its speed at point C if the track is frictionless.
OleMash [197]
At A, coaster is only associated with potential energy.
At B, coaster is associated with kinetic as well as potential energy.
Since the track is frictionless, no energy will be lost when coaster reaches from point A to point B. Therefore, according to conservation of energy, total energy at A should be equal to total energy at B.
Total energy at A = mgh = mg(12) 
Total energy at B = mgh+ mv²/2 = mg(2) + mv²/2
∴12mg = 2mg + mv²/2
∴(12g-2g)×2 = v²
∴v² = 20g
∴v = 14m/s.

Again conserving energy at points B and C.
Total energy at B = 2mg + m(14)²/2 
Total energy at C = 4mg + mv²/2
∴2mg + m(14²)/2 = 4mg + mv²/2
Solving this you get,
v = 12.52 m/s.
Therefore, speed of roller coaster at point C is 12.52 m/s.

A traveling wave has wavelength 0.50 m, speed 20 m/s. Find the wave frequency.
BigorU [14]
Frequency = (speed) / (wavelength) = 20 / 0.5 = 40 per second = 40 Hz.
