Which formulas have been correctly rearranged to solve for radius? Check all that apply. r = GM central/v^2 r =fcm/v^2 r =ac/v^2

jek_recluse [69]

The orbital radius is: $r=\frac{GM}{v^2}$

Explanation:

The problem is asking to find the radius of the orbit of a satellite around a planet, given the orbital speed of the satellite.

For a satellite in orbit around a planet, the gravitational force provides the required centripetal force to keep it in circular motion, therefore we can write:

$\frac{GMm}{r^2}=m\frac{v^2}{r}$

where

G is the gravitational constant

M is the mass of the planet

m is the mass of the satellite

r is the radius of the orbit

v is the speed of the satellite

Re-arranging the equation, we find:

$\frac{GM}{r}=v^2\\r=\frac{GM}{v^2}$

A diffraction grating is illuminated simultaneously with red light of wavelength 660 {\rm nm} and light of an unknown wavelength

Tanzania [10]

Answer:

$\lambda = 420 nm$

Explanation:

As we know that position of maximum on the screen in diffraction pattern is given as

$y = (\frac{2N + 1}{2})\frac{\lambda L}{d}$

here we know that

position of third maximum due to red color light and position of fifth maximum of unknown wavelength are same

so we have

$\frac{7 \lambda_r L}{2d} = \frac{11 \lambda L}{2d}$

so we have

$\lambda = \frac{7}{11} \lambda_r$

$\lambda = \frac{7}{11}(660 nm)$

$\lambda = 420 nm$

How do you calculate the following:<br> Final Velocity?<br> Acceleration?<br> and Force?

kicyunya [14]

Wait like the equations, or is there an actual question?

Equations are

Final velocity (Vf) = Initial velocity (Vi) + Acceleration (a) x Time (t)
Acceleration (a) = (Final velocity [Vf] - initial velocity [Vi]) divided by Time (t)
Force (f) = Mass (m) x Acceleration (a)

(Short version)

Vf = Vi + a(t)
a = (Vf - Vi) divided by t
F = m x a

An object moves 20 m east in 30 s and then returns to its starting point taking an additional 50 s. If west is chosen as the pos

disa [49]

The sign associated with the average velocity of the object is negative.

<h3>Average velocity of the object</h3>

The average velocity of the object is calculated as follows;

Average velocity = (v1 + v2)/2

v1 = -20/30 = -0.667 m/s

v2 = 20/50 = 0.4 m/s

Average velocity = (-0.667 + 0.4)/2

Average velocity = -0.134 m/s

Thus, the sign associated with the average velocity of the object is negative.
