Explanation:
what is the smallest crater that each of these telescopes could resolve on our moon?
For moon ;
s = 3.8 × 10 ⁸ m
y = 1.22 λs/D
where;
λ = 400 nm = 400× 10 ⁻⁹
D = 2.4 m
The smallest crater for the hubble space is calculated as follows:
For Aceribo ;
y = 1.22 λs/D
where :
λ = 75 cm = 0.75 m
D = 305 m
Answer:
Explanation:
Given
radius of ferris wheel is 20 m
It completes 6 turns in 1 min
i.e. 1 turn in 10 sec
Therefore its angular velocity is
(a)Period of motion is 10 s
Magnitude of centripetal acceleration is
(b)Highest point will be 40 m
(c) lowest point 0 m i.e. at ground
Gravitational force between two masses is given by formula
here we know that
now from the above equation we will have
so above is the gravitational force between car and the person
