Answer:
firstly,
ke=1÷2mv^2
on putting same ke by increasing mass by 16 times new velocity becomes v'
then
ke=1÷2×16m×v'^2
from above we can write
1÷2mv^2=1÷2×16m×v'^2
v^2=16v'^2
1÷4v=v'
hence original velocity should be decreased by 4 times to keep same ke
The radioactive tracer (radiopharmaceuticals) is used to assess bodily function and diagnosing and treating the disease. It is made up of carrier molecules bondeed tightly to radioactive atom. Some interact with specific protein or sugar in the body of the person. Radioactive tracer can be administered through intravenous injection, inhalation, oral ingestion, or direct injection into an organ.
Average force =3216N
How this is calculated?
Given:
We know that,
I=Δp(according to impulse momentum theorem)
I= Δt
So,Δt=Δp
=3216N
What is the average force?
- The average force is the force exerted by some object moving at some defined rate of speed i.e. velocity for a defined period of time.
- The word average here is used to indicate that this is not an instantaneous or precisely measured velocity.
