I believe the answer is A.
Hope This Helps! Have A Nice Day!!
Answer:
R = 28.125 ohms
Explanation:
Given that,
The voltage of a bulb, V = 4.5 V
Current, I = 0.16 A
We need to find the resistance of the filament. Using Ohm's law,
V = IR
Where
R is the resistance of the filament
So,
So, the resistance of the filament is equal to 28.125 ohms.
Answer with Explanation:
We are given that
Restoring force,
We have to find the work must you do to compress this spring 15 cm.
Using 1 m=100 cm
Work done=
W=
![W=k[\frac{(\Delta s)^2}{2}]^{0.15}_{0}+q[\frac{(\Delta s)^4}{4}]^{0.15}_{0}](https://tex.z-dn.net/?f=W%3Dk%5B%5Cfrac%7B%28%5CDelta%20s%29%5E2%7D%7B2%7D%5D%5E%7B0.15%7D_%7B0%7D%2Bq%5B%5Cfrac%7B%28%5CDelta%20s%29%5E4%7D%7B4%7D%5D%5E%7B0.15%7D_%7B0%7D)
Ideal spring work=

There are two types of energies that are taking place in the fruit is weighed in a spring scale. These are the gravitational potential energy and the elastic potential energy. The gravitational potential energy could be primarily attributed to the elevation of the fruit with respect to the ground.
A circuit breaker is an automatic device for stopping the flow of current in an electric circuit as a safety measure.
A magnetosphere is the region surrounding the earth or another astronomical body in which its magnetic field is the predominant effective magnetic field.
