Velocity - v =0 m/s,

initial velocity - v(0)= 40 m/s

a - acceleration,

time - t = 12 s.

v=v(0) - at

0 = 40m/s - a*12s

12a = 40

a = 3.3 m/s²

A 10.0 cm3 sample of copper has a mass of 89.6

Romashka-Z-Leto [24]

Density is mass divides by volume, so
89.6g / 10cm^3 =8.96g /cm^3

*cm^3 is a standard unit of volume*

A pole that is 2.9m tall casts a shadow that is 1.32m long. at the same time, a nearby tower casts a shadow that is 37.75m long.

Mrrafil [7]

$\frac{2.9}{1.32}$ = $\frac{x}{37.75}$

x = 82.93 m

Two students side in carts opposite to one another in a spinning Ferris wheel as shown.

german

Net work done on student B by the Ferris wheel in moving from the top to the bottom is mathematically given as

net work done on A =0.

Generally the equation for the work energy theorem is mathematically given as

net work done on A = change in kinetic energy of A.

Where, angular velocity is constant.

change in kinetic energy = 0.

Hence, from work energy theorem,

net work done on A =0.

Certain x-rays have a frequency of 1.0×1019hz. calculate their wavelength in air.

Murljashka [212]

For any electromagnetic wave, the relationship between frequency and wavelength is given by
$\lambda = \frac{c}{f}$
where
$\lambda$ is the wavelength
c is the speed of light (the speed of the electromagnetic wave)
f is the frequency

For the X-rays in our problem, the frequency is $f=1.0 \cdot 10^{19}Hz$ , while the speed of light is $c=3.0 \cdot 10^8 m/s$ , so the wavelength of this radiation is
$\lambda= \frac{3 \cdot 10^8 m/s}{1.0 \cdot 10^{19} Hz} =3 \cdot 10^{-11} m$

Why is light-year not related to time? (I just need scientific evidence why it isn't related to time)

valkas [14]

Answer:

A light year is a measure of distance as opposed to a time measurement. This is because a light year is the distance light can travel in the time of a year.
