For any force and any mass, the acceleration is always
(the strength of the force) divided by (the mass) .
If a force of 5 newtons is applied to a mass of 5 kg, the acceleration will be
(5 Newtons) / (5 kg) = <em>1 m/s²</em>
Answer:
speed
Explanation:
its the speed
because the formula for deriving speed is distance/time
the unit for distance is metre
the unit for time is seconds
so speed is metre/seconds
so speed us m/s.
Answer:
Explanation:
Lower the refractive index , higher the wave length
Refractive index becoming high reduces the velocity and hence wavelength as frequency remains unchanged.
So refractive index 1.4831 will correspond to wavelength of 450 nm.
For refractive index is 1.4831 , angle of incidence i , angle of refraction r .
Sin i / Sinr = 1.4831
sin65 / sinr = 1.4831
sir r = sin65 / 1.4831
= .9063 / 1.4831
= .6111
r = 37.67 degree
For refractive index is 1.4754 , angle of incidence i
Sin i / Sinr = 1.4754
sin65 / sinr = 1.4754
sir r = sin65 / 1.4754
= .9063 / 1.4754
= .61427
r = 37.9 degree
angle between two refracted ray
37.9 -37.67
= 0. 23 degree
Answer:
B = 1.823 T.
Explanation:
Given,
Number of turns,N = 170 turn
Side of square loop,L = 22 cm
Maximum torque, τ = 295 N.m
Current on the loop, I = 20 A
Magnetic strength = ?
Torque = N BIA
300 = 170 x B x 20 x 0.22²
300 = 164.56 B
B = 1.823 T.
Hence, the magnetic field strength is equal to B = 1.823 T.
