a the atom loses 1 proton to have a total of 34
Answer:
1.23 m/s
Explanation:
p=mv
57.2 = 46.5v
v= 57.2/46.5
v= 1.23
If you want to verify your answer, just insert the value of v in the equation.
<span>Volume of cylinder = pi*r*2*L
As, from the above formula,volume is directly proportional to length,
So, if we increase in length also increases in volume by 0.22%
we know

As, density is inversely proportional to volume it means increasing in volume decreases the density by 50.22%

Answer:
The magnetic flux density is
Explanation:
Given that,
Distance = 0.36 m
Current = 3.8 A
We need to calculate the magnetic flux density
Using formula of magnetic field
Where,
r = radius
I = current
Put the value into the formula
Hence, The magnetic flux density is
Answer:
Coefficient of friction will be 0.296
Explanation:
We have given initial speed of the stone u = 8 m /sec
It comes to rest so final speed v = 0 m /sec
Distance traveled before coming to rest s = 11 m
According to third equation of motion
So
Acceleration due to gravity
We know that acceleration is given by
So
So coefficient of friction will be 0.296
