Answer:
<em>The mass of the block is 0.025 kg</em>
Explanation:
<u>Mass-Spring Harmonic Motion</u>
When a mass m is attached to a spring of constant k, they produce a simple harmonic motion which angular frequency is
We also know
which means
Squaring
Solving for m
We have
Operating
Simplifying and computing
The mass of the block is 0.025 kg
Answer:
88.89 cm
Explanation:
We are given that
Distance between bulb and wall=4 m=
1 m=100 cm
Let h be the height of object
Object distance=-u
Image distance= v
Height of object=2h
Magnification=
Lens formula
Answer:
Electrical Energy and Sound Energy
Explanation:
Answer:
This system uses angular momentum and torque to do work on objects, typically against the force of gravity. The wheel and axle simple machine is closely related to gears.
