A 7300 N elevator is to be given an acceleration of 0.150g by connecting it to a cable of negligible weight wrapped around a tur
Firlakuza [10]

Answer:

α =18.75  rad/s²

Explanation:

Given that

Acceleration a = 0.15 g

We know that   g =10 m/s²

a= 0.15 x 10 = 1.5  m/s²

d= 16 cm

Radius r= 8 cm

Lets take angular acceleration =α rad/s²

As we know that

a= α r

Now by putting the values

1.5 = α  x 0.08

α =18.75  rad/s²

Guillaume Amontons first took a stab at measuring absolute zero in 1702. What would be the most reasonable way it would have bee
Oliga [24]

He would measure the speed of molecules as the temperature gets colder until the temperature is measured at which motion stops.

<h3>What is the absolute zero?</h3>

The absolute zero refers to the temperature at which the gas seems to stop moving. Recall that temperature is the measure of the average kinetic energy of the molecules of a gas.

Hence, if Guillaume Amontons first took a stab at measuring absolute zero in 1702, he would measure the speed of molecules as the temperature gets colder until the temperature is measured at which motion stops.

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. What is the BEST explanation of the
MrRissso [65]

The answer is shorter the wavelength, higher the frequency and higher the energy.

<u>Explanation:</u>

The sun radiates UV energy in a wide range of wavelength, which are invisible to human eyes. The shorter the wavelength, the more energetic the radiation, and the greater the potential for harm.

The relationship between wavelength and wave energy is shorter the wavelength, higher the frequency and higher the energy.

It has a frequency ranges from 8 × 10^14 to 3 × 10^16 cycles per second, or hertz (Hz), and wavelengths id about 380 nanometers to about 10 nm.
