Answer:

White light is composed by a range of colors, this was discovered by Isaac Newton when he observed that a beam of white light was refracted (the different rays of light are diverted depending on their wavelengths) when passing through a prism . This phenomenon was later called dispersion

If the moon disappeared what effect would this have on the earths tides

iogann1982 [59]

The moon has a huge impact on the tides. With the Moon gone, the oceans would become much calmer. The Sun still has its effect on them known as the solar tides. Surfers wouldn't be completely devoid of waves.

A Morrison’s fuel truck is traveling at a speed of 5 miles per hour for 5 minutes what distance does it travel?

madam [21]

Answer: 2,200 feet

Explanation:

Use the following conversions: 1 mile = 5280 feet, 1 hour = 60 minutes

$\dfrac{5\ miles}{1\ hour}\times \dfrac{5280\ ft}{1\ mile}\times \dfrac{1\ hour}{60\ min}\times 5\ min=\dfrac{132,000}{60}ft=\large\boxed{2,200\ ft}$

Two bulbs marked 200 W-250 V and 100 W-250 V are joined in

lozanna [386]

Answer:

P = 66.67 W

Explanation:

Joule Heating

It's the process by which the electric current passing through a conductor produces heat.

Also known as Joule's first law or the Joule–Lenz law, states that the power of heating generated by an electrical conductor (P) is proportional to the product of its resistance (R) and the square of the current (I).

It can be described by the equation that follows:

$P = I^2.R$

Also, we can calculate the voltage V with the formula of Ohm's law:

$V = I.R$

Combining both equations, power can be related to the voltage:

$\displaystyle P=\frac{V^2}{R}$

Given the power and the voltage, the resistance can be calculated by solving for R:

$\displaystyle R=\frac{V^2}{P}$

There are two bulbs marked P=200W V=250V and P=100 W V=250.

The first bulb has a resistance of:

$\displaystyle R_1=\frac{250^2}{200}$

$\displaystyle R_1=312.5\Omega$

The first bulb has a resistance of:

$\displaystyle R_2=\frac{250^2}{100}$

$\displaystyle R_1=625\Omega$

When connected in series, the total resistance is

$R = R_1 + R_2=312.5\Omega+625\Omega$

$R=937.5\Omega$

The total power consumed when connecting them to a V=250 V supply is:

$\displaystyle P=\frac{250^2}{937.5}$

P = 66.67 W

Which is the average acceleration during the time Interval 0 seconds 10 seconds?

weqwewe [10]

Average acceleration = (change in speed) / (time for the change)

In this case . . .

Average acceleration = (speed at the end - speed at the beginning)/10sec.

We can't be any more specific without knowing the difference
between the beginning speed and the ending speed.
