Answer:
5m/s/s
Explanation:
10N bc you subtract 10N from 20N and you get 10
a=f/m
F=10N
m=2kg
10/2=5
Answer:
A unit is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWh) of electricity.
Answer: R = 28 degree
Explanation:
The given parameters are:
Refractive index n = 1.52
Incident angle I = 45 degree
According to Snell law,
Sin I/Sin R = n
Where
I = angle of incidence
R = angle of refraction
n = refractive index
Substitute all the parameters into the formula
1.52 = sin 45/ sin R
Make sinR the subject of formula
Sin R = sin 45/1.52
Sin R = 0.46520
R = sin^-1(0.46520)
R = 27.72 degree
Therefore, the angle of refraction will be 28 degrees approximately.
