Answer:
Explanation:
In this case, we need to find the value of expression :
On solving, we get the value of given expression as :
x = 9.7827
In scientific notation, we get the value of x as :
a = 9.78
k = 0
Hence, this is the required solution.

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.
Answer:
70 m/s
Explanation:
The frequency of earthquake = 2.0 Hz
The wavelength = 35 m
How fastbthw earthquake is t traveling is given bythw velocity of the wave, velocity of wave is related to frequency and wavelength using the formula :
V = frequency * wavelength
V = 2 * 35
V = 70 m/s
