An object with a mass of 5kg accelerates at 2m/s2. How much force in Newtons(N) is needed to cause this to happen?

This is a team building exercise to perform interference experiments, where the separation of the slits is d = 1 m = 1 10⁻³ m and the distance to the screen L = 1.5 m

Constructive interference occurs when the path difference is equal to an integer number of wavelengths

d sin θ = m λ

a) The center of the two-ray pattern has the same length so the intensity is MAXIMUM, that is, the pattern is bright

b) to find the distance let's use trigonometry

tan θ= y / L

tan θ =sin θ/cos θ= sin θ

because the angles are small

we substitute

y = $\frac{m \lambda L}{d}$

let's calculate

y = 10 550 10⁻⁹ 1.5 / 1 10⁻³

y = 8.25 10⁻³ m

c) for this part the incident light must be white or polychrome light

let's find the distance (y) for some colors, in the first order

Violet λ = 400

y = 1 400 10⁻⁹ 1.5 / 1 10⁻³

y = 6 10⁻⁴ m

green λ = 500 nm

y = 1 500 10⁻⁹ 1.5 / 1 10⁻³

y = 7.5 10⁻⁴ m

yellow λ = 600 nm

y = 1 600 10⁻⁹ 1.5 / 1.10⁻³

y = 9 10⁻⁴ m

lam λ = 700 nm

y = 1 700 10⁻⁹ 1.5 / 1. 10⁻³

y = 1.05 10⁻³ m

violet, green, orange, red

the distance increases with the wavelength increases

d) To find the wavelength we must measure the distance y from the center of the slit for various interference orders and using the equation we can find the wavelength of rationality

A stuntwoman is going to attempt a jump across a canyon that is 77 m wide. The ramp on the far side of the canyon is 25 m lower

charle [14.2K]

Answer:

She will make the jump.

Explanation:

We have equation of motion , $s= ut+\frac{1}{2} at^2$ , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
