Answer:

The index of refraction of a diamond is 2.4175

Explanation:

refractive index

n = c/v

n = refractive index

c = speed of light

v = velocity of light thru the material

Why would a rocket fall vertically downwards if it was launched vertically upwards​
IgorC [24]

Answer:

It would because the shape of the rocket is designed to be able to slice through the air as smooth as possible and now you may be thinking that air is already smooth but when you try to push something as large and heavy like a rocket then the shape of the rocket will be very important. The bottom of the rocket is flatter then the top so it is not designed to fly smoothly through the air. So the rocket would fall vertically downward(If it was still in one piece)because of it's shape. It is easier for the top of the rocket to go smoothly through the air then the bottom.

Explanation:

I am 90% sure this is correct but if I'm not please tell me

A square 1300-turn coil with the area of 0.2 m2 is situated in the xy-plane in a region where the magnetic field is (50k) μT. Wh
givi [52]

Answer:

e = 65 mA

Explanation:

given,

number of turn = 1300

Area = 0.2 m²

B = 50 x 10⁻⁶T

t = 0.2 s

coil rotate in x-z plane

θ = 90°  to θ = 0°

maximum induced emf

e = -\dfrac{BAn(cos \theta_f - cos\theta_i)}{\Delta t}

e = -\dfrac{1300 \times 0.2 \times 50\times 10^{-6}(cos 90^0- cos0^0)}{0.2}

e =0.065

e = 65 mA

A heavy copper ball of mass 2 kg is dropped from a fiftieth-floor apartment window. Another one with mass 1 kg is dropped immedi
STALIN [3.7K]

Answer:

C

Explanation:

Because everything on Earth falls at the same speed, the masses of the balls do not matter. Since the acceleration due to gravity is constant, their speeds will both be increasing at the same rate, and therefore the difference in speeds would remain constant until they hit the ground. Hope this helps!

Pls help waves for physics
djverab [1.8K]

Answer:

b) 252 Hz or 260 Hz

c) 0.25 s

Explanation:

b) The frequency of the beats is 4 Hz, and one tuning fork has a frequency of 256 Hz.  Therefore, the second tuning fork is either 4 Hz lower or 4 Hz higher.

f = 252 Hz or 260 Hz

c) Period is the inverse of frequency.

T = 1/f

T = 1 / (4 Hz)

T = 0.25 s
