The work done on the bullet is force•distance. This is also equivalent to the energy it has leaving the muzzle (work energy theorem). This kinetic energy is (1/2)(0.006kg)(336m/s)^2=338.7J. Then 338.7J=F•0.83m
F=338.7/0.83=408N
Answer:
It's STERIC NUMBER.
Explanation:
The steric number is the number of shared pairs of electrons on a central atom of a molecule (σ sigma bond) plus the number of lone pairs on the central atom.
Answer:
2A
Explanation:
Given parameter:
Quantity of charge = 2C
Time taken = 1s
Unknown:
The current passing through the ring = ?
Solution:
Current can also be defined as the quantity of charge that passes through a conductor per unit of time:
I =
So;
I =
= 2A
Answer:
