Explanation:
The blocks are spinning around the center of mass, but they're also sliding horizontally. So they still have a positive displacement.
Answer:
The procedure is the plan for how you will conduct your experiment.
Explanation:
<span>First you have to convert 7.68 cal/sec to cal/min to do that, just multiply by 60 So it will be 460.8 cal/min now convert that to kcal/min kcal = kilocalories = 1000 calories. so just divide by 1000 and youll have your answer in kcal/min </span>
A) To obtain an inverted image of an object of same size a convex lens is used.
B)
In this question we have given
Distance between candle flame and screen=4
it means distance between candle flame and lens +distance between lens and screen =4m
u+v= 4m
u= v
therefore, 2u= 4m
or, u=-2m ( u is taken negative because it lies on left side of the lens)
and v=2m
we have to find the focal length of convex lens


Hence, Focal length of the lens is 1m
and lens should be placed at a distance of 2m from the flame
Answer:
The answer is C, a thermometer reads 0.1 degree higher than it should.
