One fourth of the moon's lighted side is visible from Earth

when the Moon is at position-D in its orbit ... it looks like a

crescent in the sky.

There's a massive blunder in this drawing.

Look at the Moon at Third Quarter.

It's drawn with its dark side toward the sun, and its

lit-up side away from the sun ! That's just silly.

Teachers can make mistakes too.

Find the displacement of a car that accelerates at -6m/s2 for 5 sec to a final velocity of 60m/s.

Anvisha [2.4K]

Answer:

Explanation:

2as=vf²-vi²

2as=(60)²-0²

2as=3600 m/s

s=3600/2*a

s=3600/2*(-6)

s=3600/-12

s=-300 m

Light of wavelength 550nm in air is found to travel at 1.96

Sedaia [141]

Answer:

ν = 5.45 x 10¹⁴ Hz

Explanation:

given,

wavelength of light = 550 nm

= 550 x 10⁻⁹ m

speed of light = 1.96 x 10⁸ m/s

speed of sound = 3 x 10⁸ m/s

frequency of the light = ?

we know.

$v = \nu \lambda$

frequency of the light in the liquid is same as the frequency of the light in the air.

ν is the frequency of light

$\nu = \dfrac{v}{\lambda}$

$\nu = \dfrac{3\times 10^{8}}{550\times 10^{-9}}$

ν = 5.45 x 10¹⁴ Hz

Hence, the frequency of light in the liquid is equal to ν = 5.45 x 10¹⁴ Hz

A proton and an electron are moving in the +x direction in a magnetic field in the +z

Aleksandr [31]

Answer:

Explanation:

Force on a moving charge is given by the following relation

F = q ( v x B )

for proton

q = e , v = vi , B = Bk

F = e ( vi x Bk )

= Bev - j

= - Bevj

The direction of force is along negative of y axis or -y - axis.

for electron

q = - e , v = vi , B = Bk

F = - e ( vi x Bk )

= - Bev - j

= Bevj

The direction of force is along positive of y axis or + y - axis.
