Answer:
a) s
b) 3.41 mm
Explanation:
a)
We take the speed of light, c = m/s and the refractive index of glass as 1.517.
Speed = distance/time
Time = distance/speed
Refractive index, n = speed of light in vacuum / speed of light in medium
b)
We take the refractive index of water as 1.333.
Speed in water = speed in vacuum / refractive index of water
Distance = speed * time
d = 3.41 mm
Answer:
7.7 GJ
Explanation:
Kinetic wnergy is given by
KE=½mv²
Where KE denote kinetic energy, m is the mass of object and v is velocity. Normally, m is in Kg and v in m/s
Conversion
Given speed of satelite in km/h, we convert it into m/s by multiply by 1000/3600
20000*1000/3600=5555.5555555555
Rounded off, m=5555.56 m/s
Substituting 500 kg for m and 5555.56 m/s for v then
KE=½*500*5555.56²=7,716,061,728.4 rounded off as
KE=7.7 GJ
Answer:
maximum amplitude = 0.08 m
Explanation:
Given that
Time period T= 0.58 s
acceleration of gravity g= 9.8 m/s²
We know that time period of simple harmonic motion given as
T = 2π/ω
0.58 = 2π/ω
ω = 10.83rad/s
ω=angular frequency
Lets take amplitude = A
The maximum acceleration given as
a= ω² A
The maximum acceleration should be equal to g ,then block does not separate
a= ω² A
9.8 = 10.83² A
A = 0.08m
maximum amplitude = 0.08 m
