Refraction of light in water

Answer:

The answer is Refraction

Explanation:

Refraction is the change in direction and speed that a wave experiences when passing from one medium to another with a different refractive index. It occurs when the light passes from one propagation medium to another with a different optical density, undergoing a change of speed and a change of direction if it does not affect the surface perpendicularly.

A NASA explorer spacecraft with a mass of 1,000 kg takes off in a positive direction from a stationary asteroid. If the velocity

Jet001 [13]

Before the launch, the momentum of the (spacecraft + asteroid) was zero. So after the launch, the momentum of the (spacecraft + asteroid) has to be zero.

Momentum = (mass) x (velocity)

Momentum after the launch:

Spacecraft: (1,000 kg) x (250 m/s) = 250,000 kg-m/s

Asteroid: (mass) x (-25 m/s)

Their sum: 250,000 - 25(mass) .

Their sum must be zero, so 250,000 kg-m/s = (25 m/s) x (mass)

Divide each side by 25 : 10,000 kg-m/s = (1 m/s) x (mass)

Divide each side by (1 m/s) : 10,000 kg = mass

According to Newton's second law, how are acceleration and mass related? Directly or indirectly when force is constant?

Aliun [14]

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

A student runs 120 meters in 10 seconds. What is their speed? Question 6 options: 1.2 m/s 1200 m/s 120 m/s 12 m/s

aleksklad [387]

12m/s

Explanation:

Given parameters:

Distance run by student = 120 meters

Time = 10 seconds

Unknown:

Speed = ?

Solution:

Speed is the rate of change of distance with time:

Speed = $\frac{distance}{time}$

Now input the parameters:

Speed = $\frac{120}{10}$ = 12m/s

A secret agent is locked in a room. He pushes against the door but cannot open it. Finally, he falls to the floor exhausted. Has

Vitek1552 [10]

Answer: There is not work done at the door because the door did not move.

Explanation: Work is defined as the movement done by a force.

So if you move to apply a force F in an object and you move it a distance D, the work applied on the object is

W = F*D

In this case, the secret agent pushes against the door, so there is a force, but the agent does not move the door, so D = 0, so there is no motion of the door, which implies that there is no work done at the door.
