Answer:
6.67 minutes
Explanation:
d = Diameter of first telescope = 2 m
d' = Diameter of second telescope = 6 m
Increase in diameter
Time to collect light for first telescope
t = 1 hour = 60 minutes
Time to collect light for second telescope
The time taken would be 6.67 minutes
Answer:
Explanation:
Let's start by calculating the angular velocity of the Moon. We know that the period is:
So now we can calculate its angular velocity:
The centripetal acceleration is given by
where
is the radius of the orbit
Substituting,
A tornado is a natural force It is a very strong wind that causes thing to damage
Answer:
0.1m
Explanation:
k = 64N/m
Ep = 0.32J
x = ?
Ep = 1/2 * kx²
make x the subject of the formula
x² = 2Ep/k
x = √(2Ep/k)
x = √(0.64/64)
x = √0.01
x = 0.1m
