Answer:
When light travels from one medium to another, the frequency of light does not change. However, the velocity and wavelength change.
Explanation:
Pls mark me as brainliest
Answer:
The velocity of a ball will be "-70.13 m/s".
Explanation:
The given values are:
u = 70 m
t = 0.0 s
g = a = -9.8 m/s²
s = -1 m
v = ?
As we know,
The equation of motion will be:
⇒ 
On substituting the estimated values, we get
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
In downward direction, it will be:
⇒ 
Every organism may classified into seven level of classifications, such that each level contains organisms with similar characteristics. Kingdom is the largest and the broadest level of classification while species is the smallest and most specific level of classification. Therefore from the largest to the smallest the order is as follows:
Kingdom
Phylum
Class
Order
Family
Genus
Species
During phase changes, energy changes are usually involved. For example, when solid dry ice vaporizes (physical change), carbon dioxide molecules absorb energy. Meanwhile, when liquid water becomes ice energy is released.

Answer: 0.57
Explanation:
Let's begin by explaining that two angles are complementary when they sum is 
:
Having this clear, let's find 
from the following trigonometric function:
Now that we have the value of , let's find 
:
This is the complement of angle
Then, the cosine of the complement is:
This is the answer
