Two adjoining plane mirrors are separated by an angle of 100°. Light is incident on the first mirror at an angle of 70°. The lig
ht reflects toward the second mirror and is then reflected from it. At what angle is the light reflected from the second mirror?
2 answers:
Answer:
The angle is the light reflected from the second mirror is 30°
Explanation:
Given that,
Angle between mirrors = 100°
Angle of incident = 70°
We know that,
The incident angle is equal to the reflected angle.
We need to calculate the angle BCA
According to figure,
In ,
Put the value into the formula
We need to calculate the angle is the light reflected from the second mirror
Using relation of incident and reflection
We know that, i = r
So, i=r=30°
Hence, The angle is the light reflected from the second mirror is 30°

Answer:
3.25 seconds
Explanation:
It is given that,
A person throws a baseball from height of 7 feet with an initial vertical velocity of 50 feet per second. The equation for his motion is as follows :
Where
s is the height in feet
For the given condition, the equation becomes:
When it hits the ground, h = 0
i.e.
It is a quadratic equation, we find the value of t,
t = 3.25 seconds and t = -0.134 s
Neglecting negative value
Hence, for 3.25 seconds the baseball is in the air before it hits the ground.
Answer:
The energies corresponding to each of the allowed orbitals are called energy levels.
Explanation:
A scientist known as Niels Bohr put forward that electrons in an atom covers some permitted orbitals with a specific energy. In other words, the energy of an electron in an atom is not continuous, but 'quantized.' The energies corresponding to each of the allowed orbitals are called energy levels.
