Answer:
answer is C
Explanation:
acceleration is rate of changing velocity in a time
Answer:
A. elements of the same kind with different numbers of neutrons
Explanation:
As we know that an atom is represented by
here we know that
z = atomic number
A = atomic number + number of neutrons
now if the number of neutrons in an atom is different but having same number atomic number then the combination of such group of atoms is known as isotopes.
So here we have
so above is the example of isotopes
Answer:
It is a resistor since as u increases v increases so they are directly propotional
Answer:
The acceleration of the wallet is
Explanation:
Given that,
Radius of purse r= 2.30 m
Radius of wallet r'= 3.45 m
Acceleration of the purse
We need to calculate the acceleration of the wallet
Using formula of acceleration
Both the purse and wallet have same angular velocity
Hence, The acceleration of the wallet is
