Phys 165 Module 6 Exam
A bob with a large mass is supported via a rope and swings to and fro at the same time as
friction appearing at the machine is negligible. For this pendulum, answer the subsequent
questions:
a. In which part of the swing does the pendulum bob have the maximum kinetic power?
B. In which part of the swing does the pendulum bob have the most gravitational capacity
electricity? - ANS-a) *Kinetic Energy* In the middle of the swing or at the lowest of the swing
b) *Gravitational Potential* At both cease of the swing or on the pinnacle of the swing
- *Moves the fastest* within the middle of the swing
- *stops for a second* at either give up of the swing
- *equilibrium* in the center
- *has the most electricity* any part of the swing
A light ray is moving from air into oil which that has an index of refraction of 1.Forty six.
A. When the ray of light is in the oil, how speedy does it flow?
B. If the perspective of incidence is 37.5∘, what's the perspective of refraction? - ANS-a) v= c/n
v= 3x10^8/ 1.46
*v= 2.05x10^8 m/s*
b) n1sin(ɵ)=n2sin(ɵ)
1.0 sin(37.5)=1.Forty six sin(ɵ)
*ɵ = 24.Sixty four°*
Glasses allow human beings to look greater without a doubt by way of forcing light to transport
thru the glass and alternate instructions. What belongings of waves do glasses use to do this? -
ANS-Refraction
In a laboratory, water waves are created in a pool of water via dipping a bar into the water at an
even rate. If the bar is dipped in the water 35 instances in precisely 20.Zero s, what is the
duration and frequency of the waves inside the water? - ANS-a) Use T=∆t/# of cycles solution in
seconds
T= 20/ 35 *zero.57 seconds*
b) f=1/T Answer in Hz
f= 35/ 20 *1.Seventy five--- 1.Eight H*
Of the subsequent objects in motion, which one is exhibiting easy harmonic movement? -
ANS-Pendulum swinging to and fro, a mass bouncing on a spring, a metronome
Periodic movement in which the restoring pressure and acceleration of the item are both directly
proportional to the gap from the equilibrium function
