Answer:
0.012-m
Explanation:
∆L = α × Lo × (T-To)
α is the coefficient of linear expansion = 12 × 10-6 K-1
Lo = Initial length = 25-m
∆L = Change in length
(T-To) = 40 K
∆L = 12 × 10-6 × 25 × 40
∆L = 0.012-m
That is a lunar eclipse. At night, when the Earth is between the Sun and the moon, the moon would appear to be red. Just for future reference, a solar eclipse is when the Moon is between the Sun and Earth. Speaking of which, check out the solar eclipse this August!
Answer:
Explanation:
Given
velocity of boat with respect to river 
velocity of river is 
River is 3.5 km wide
Suppose boat leaves at an angle of
with vertical such that it reaches exactly opposite end of initial Point
Therefore
component will balance the river Flowso that sin component helps to cross the river
