Answer:

Space junk, or space debris, is any piece of machinery or debris left by humans in space. It can refer to big objects such as dead satellites that have failed or been left in orbit at the end of their mission. It can also refer to smaller things, like bits of debris or paint flecks that have fallen off a rocket.

Answer:

In addition to derelict man-made objects left in orbit, other examples of space debris include fragments from their disintegration, erosion and collisions or even paint flecks, solidified liquids expelled from spacecraft, and unburned particles from solid rocket motors. Space debris represents a risk to spacecraft.

A ray of light contains two colors: red with wavelength of 660 nm and blue with wavelength 470 nm. The ray passes through two na
densk [106]

Answer:

The distance on the screen between the first-order bright fringes  for each wavelength is 3.17 mm.

Explanation:

Given that,

Wavelength of red = 660 nm

Wavelength of blue = 470 nm

Separated d= 0.30 mm

Distance between screen and slits D= 5.0 m

We need to calculate the distance for red wavelength

Using formula for distance

y=\dfrac{\lambda D}{d}

Where, D = distance between screen and slits

d = separation of slits

Put the value into the formula

y=\dfrac{660\times10^{-9}\times5.0}{0.30\times10^{-3}}

y=11\ mm

For blue wavelength,

Put the value into the formula again

y'=\dfrac{470\times10^{-9}\times5.0}{0.30\times10^{-3}}

y'=7.83\ mm

We need to calculate the distance on the screen between the first-order bright fringes for each wavelength

Using formula for distance

\Delta y=y-y'

\Delta y=11-7.83

\Delta y=3.17\ mm

Hence, The distance on the screen between the first-order bright fringes  for each wavelength is 3.17 mm.

A rocket is moving at 1/4 the speed of light relative to Earth. At the center of this rocket a light suddenly flashes. To an obs
Sedaia [141]

Answer:

B. the light will reach the front of the rocket at the same instant that it reaches the back of the rocket.

Explanation:

To an observer at rest in the rocket who can't see either sides of the rocket, the speed of the light is constant which means the distance to the front or the back is same and would appear to reach the rocket at the same time.

Although from the point of view of the person on the earth, the front of the rocket is travelling in opposite direction of the light while the back of the rocket is moving closer to the light. This means that the distance travelled by the light going forward will be longer going backwards. And since the speed of light is constant in both directions, the light will reach the back of the rocket before it reaches the front  for the observer on the earth.

Answer:

Weight

Explanation:

Weight is the downward pull on an object due to gravity.

For example, the moon has less gravity than Earth so we would weigh less on the moon. Our Mass and volume always stay the same but our weight could change.
