Refraction is the bending of light<span> </span>
Answer:
Refractive index of unknown liquid = 1.56
Explanation:
Using Snell's law as:
Where,
is the angle of incidence ( 65.0° )
is the angle of refraction ( 53.0° )
is the refractive index of the refraction medium (unknown liquid, n=?)
is the refractive index of the incidence medium (oil, n=1.38)
Hence,
Solving for
,
Refractive index of unknown liquid = 1.56
Answer:
an oscillator consisting of a material point of m = 200g vibrates under the action of an elastic force according to the equation y = 0.2sin (π / 4 • t + π / 16) (m)
calculate the period and frequency of the oscillation
calculate the speed and acceleration
calculate the Total Energy
#1
Work done is given by

here we know that
F = 157 N
d = 14.5

now from the above formula

#2
By energy conservation
Initial total potential energy of egg = final total kinetic energy of egg




#3
By momentum conservation we know that




#4
by momentum conservation we know that

let direction of velocity of Jay Z car motion is positive direction
now we will say



Yes Jay Z is overspeeding as his speed is more than speed limit
#5
Tension force in the string will be centripetal force
so here we can say

here we know that
m = 0.63 kg
v = 7.8 m/s
R = 0.23 m
