Schach [20]3 years ago
6 0
An object that possesses mechanical energy is able to do work. In fact, mechanical energy is often defined as the ability to do work. Any object that possesses mechanical energy - whether it is in the form of potential energy or kinetic energy - is able to do work. That is, its mechanical energy enables that object to apply a force to another object in order to cause it to be displaced.

34000×0.4<br> ----------------<br> 0.02×200<br> In scientific notation
VashaNatasha [74]

Answer:

the simplified expression is written as 3.4 x 10³

Explanation:

Given expression;

\frac{34000\times 0.4}{0.02 \times 200}

in scientific notation, the expression is simplified as;

\frac{34000\times 0.4}{0.02 \times 200}  = \frac{13600}{4} = 3400 = 3.4 \times 10^3

Therefore, in scientific notation, the simplified expression is written as 3.4 x 10³

Show that the equilibrium temperature of the surface of the moon is 273 K assuming it has an albedo of 0.08.
const2013 [10]

Answer:

The equilibrium temperature of the surface of the moon can be found by the formula as follows:

T=(\frac{K_s(1-alebdo)}{4 \sigma})^{\frac{1}{4}}

Where K_s = 1366 W/m^2 is the solar constant and \sigma = 5.67 \times 10^ {-8}W/m^2K^{-4} is the Stefan's Boltzmann constant.

T=(\frac{1366(1-0.08)}{4\times 5.67 \times 10^ {-8}})^{\frac{1}{4}} = (55.41\times 10^8)^{\frac{1}{4}} = 272.7 K=273 K

Thus, the equilibrium temperature of the surface of the moon is 273 K.

Photons are generated by a microwave oven in a kitchen and by an x ray machine at a dentist’s office. which type of photon has t
Ad libitum [116K]

The different types of radiation are defined by the the amount of energy found in the photons. X-Ray photons will have greater frequency than microwaves but microwaves will have greater wavelength.

There are seven regions in the electromagnetic spectrum which in order of lowest to highest frequency are: Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays. Wavelength is inversely proportional to frequency, therefore radio waves have the longest wavelength and gamma rays have the shortest. that is why X-Ray machine photons have greater frequency and shorter wavelength while microwave photons have lower frequency but higher wavelength.

an object is moving with a speed of 35 m/s and has a kinetic energy of 1500 J, what is the mass of the object?
Elena-2011 [213]
You'd use the equation kinetic energy=mass*0.5*speed^2
So you'd rearrange this to get mass =kinetic energy /0.5 *speed^2
Which is mass= 1500J/0.5*35^2
