How long it takes to revolve around the sun
Answer:
a)
b)
Explanation:
Given:
mass of bullet,
compression of the spring,
force required for the given compression,
(a)
We know
where:
a= acceleration
we have:
initial velocity,
Using the eq. of motion:
where:
v= final velocity after the separation of spring with the bullet.
(b)
Now, in vertical direction we take the above velocity as the initial velocity "u"
so,
∵At maximum height the final velocity will be zero
Using the equation of motion:
where:
h= height
g= acceleration due to gravity
is the height from the release position of the spring.
So, the height from the latched position be:
Answer:
Explanation:
Path difference for the destructive interference of a single slit:
For the first - order minimum, n = 1, and
.........(1)
For the second - order minimum, n = 2, and
.........(2)
Dividing equation (2) by equation (1):
