Answer:
Emissions per second = 0.36
Explanation:
Please find the attached question
Solution
Given
Let X be the rate of background emission.
X = B/t
Where B = 36
And t = 100
X = 36/100 = 0.36
2kg ball
A=f/m
Higher mass is less acceleration
Answer:
d. 0V
Explanation:
The magnitude of four point charges are +3q, -q, +2q and -4q. I think you forget to mention the signs.
As we know that the potential due to the point charge that has traveled the distance d can be represented mathematically as,
= 1/4λε = 9× Nm²/C²
Now as it is mentioned in the question that all four charges are arranged in the corners of a square so there distance from the center is same. We can rewrite the above potential equation as follows.
(1)
We can find out d by the pythagoras theorem, as we are dealing with square so d is a semi diagonal.
by putting all values in equation (1)
V =
V = 0V
Answer:
0.022kg/s
Explanation:
We are given that
Mass of boiled egg=46 g=
Constant force=F=25.6 N/m
Initial displacement=
Final displacement=
Time=t=4.55 s
Damping force=
We have to find the magnitude of damping constant b.
We know that the displacement of the oscillator under damping motion is given by
For maximum displacement
Therefore ,
Substitute the values
Substitute the values
Hence,the magnitude of damping constant b=0.022kg/s
