Answer:
BC =980nm
Explanation:
Given wavelength =490nm
m=2
Required to find (OB - OC) = BC (more distant slit - nearest slit ) = dsin theta
We have dsin theta = m*wavelength
or BC = m* wavelength = 2*490nm
= 980nm = 98.000A
the batteries would heat up due to the over load of power not going into any thing and the screw driver is giving it a boost of energy
Answer:
- solution,
- Given
- load =400N
- ld=0.2m
- ed=0.6m
- effort =150N
Explanation:
efficiency =output work/input work ×100%
l×ld/e×ed×100%
400×0.2/150×0.6×100%
80/90×100%
88.89%ans
