Answer:
100 J
Step-by-step explanation:
The formula for kinetic energy is as follows:
where
KE= kinetic energy (J)
m= mass (kg)
v= velocity (m/s)
Given: m= 50 kg, v= 2 m/s
Substituting the given information into the formula:
KE
= ½(50)(2²)
= ½(50)(4)
= 100 J
Answer with Step-by-step explanation:
We are given that A, B and C are subsets of universal set U.
We have to prove that
Proof:
Let x
Then and
When then
but
Therefore, but
Hence, it is true.
Conversely , Let but
Then and
When then
Therefor,
Hence, the statement is true.
