Answer:
hope it is gonna help u raj Good day
Explanation:
The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10-34 when expressed in the unit J s, which is equal to kg m2 s -1 , where the meter and the second are defined in terms of c and ∆νCs.
Answer:
using Snells law
Oi = angle of incidence = 58.0°
ni = index of refraction of air = 1.0003
nr = index of refraction of glass = 1.47
c = speed of light in vacuum = 3 x 10^8 m/s
Or = angle of refraction = ?
ni(sinOi) = nR (sinOr)
ni( sinOi)/ nR = sinOr
arcsin(ni(sin0i))/nR = Or
arcsin( 1.0003(sin58.0)) / 1.47
Or = 35.25°
Explanation:
Answer:
Mass=3,height=50 and time=15,g=10,P=?
P=mgh/t....which is 3×10×50=1500/15=100Watts
