Answer:
d. the translucence of the object
Explanation:
the reason is that an object has a particular color as it is translucent to certain colors; it may absorb some colors and not show them at all, or they will reflect the remaining colors, the ones we are able to see. for eg: imagine you have a red dress. you see it as red, yet it is only reflecting the red color into your eyes, and is absorbing every other color in that light's color spectrum.

A conversion factor is a ratio of <u>e</u><u>quivalent</u> measures
Answer:
The angle is 25.34°.
Explanation:
Given that,
Wave length = 650 nm
Angle = 68.0°
We need to calculate the distance
For a diffraction grating
We need to calculate the angle
Using formula for angle
Hence, The angle is 25.34°.
Answer:
E = 1.45 x 10⁹ J = 1.45 GJ
Explanation:
According to the law of conservation of energy:
Potential Energy Lost by Satellite = Kinetic Energy + Internal Energy
where,
E = Internal Energy = ?
m = mass = 400 kg
g = acceleration due to gravity = 9.81 m/s²
h = height = 500 km = 500000 m
v = speed on ground = 1.6 km/s = 1600 m/s
Therefore,
<u>E = 1.45 x 10⁹ J = 1.45 GJ</u>
