Answer:
R = 1.2295 10⁵ m
Explanation:
After reading your problem they give us the diameter of the lens d = 4.50 cm = 0.0450 m, therefore if we use the Rayleigh criterion for the resolution in the diffraction phenomenon, we have that the minimum separation occurs in the first minimum of diffraction of one of the bodies m = 1 coincides with the central maximum of the other body
θ = 1.22 λ / D
where the constant 1.22 leaves the resolution in polar coordinates and D is the lens aperture
how angles are measured in radians
θ = y / R
where y is the separation of the two bodies (bulbs) y = 2 m and R the distance from the bulbs to the lens
R =
let's calculate
R =
R = 1.2295 10⁵ m
Answer:
momentum of elephant will be more than the momentum of mouse
Explanation:
As we know that momentum is the product of mass and velocity
so we can write it as
here we know that a mouse is moving with speed 1 m/s
let say mass of mouse is m1 so we have
similarly now we know that elephant is moving with speed 3 m/s
now let say the mass of elephant is of mass m2 so
now we know that mass of elephant as well as speed of elephant both are more than mouse
so momentum of elephant will be more than the momentum of mouse
To solve this problem we will apply the concepts related to the Force of gravity given by Newton's second law (which defines the weight of an object) and at the same time we will apply the Hooke relation that talks about the strength of a body in a system with spring.
The extension of the spring due to the weight of the object on Earth is 0.3m, then
The extension of the spring due to the weight of the object on Moon is a value of , then
Recall that gravity on the moon is a sixth of Earth's gravity.
We have that the displacement at the earth was , then
Therefore the displacement of the mass on the spring on Moon is 0.05m
Answer:
The displacement of the elevator between 8 s and 24 s is 6 m.
Explanation:
Given that,
Initial time = 8 s
Final time = 24 s
We know that,
Displacement :
Displacement is the difference between initial position and final position.
In mathematically,
We need to calculate the displacement
Using formula of displacement
Put the value from graph
Hence, The displacement of the elevator between 8 s and 24 s is 6 m.
