Answer:
1966 J
Explanation:
The work done by the hose on the balloon is equal to the elastic potential energy stored in it:
where
k = 130 N/m is the spring constant
x = 5.50 m is the stretching of the hose before it is being released
If we substitute these numbers into the equation, we find:
So, the work done is 1966 J.
Answer:
A <u>scientific model</u> is a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes. Scientists seek to identify and understand patterns in our world by drawing on their scientific knowledge to offer explanations that enable the patterns to be predicted.
Answer:
The radius of the sphere is 3.6 m.
Explanation:
Given that,
Potential of first sphere = 450 V
Radial distance = 7.2 m
If the potential of sphere =150 V
We need to calculate the radius
Using formula for potential
For 450 V
....(I)
For 150 V
....(II)
Divided equation (I) by equation (II)
Hence, The radius of the sphere is 3.6 m.
