Calculate the frequency of radiation with a wavelength of 1.08 x 10^-6 m. simple explanation please​
pishuonlain [190]
C = vf
c stands for the speed of waves (which is a constant that is 3 x 10^8)
v stands for the wavelength (which is given)
f stands for frequency (what we are solving for)
3 x 10^8 = (1.08 x 10^-6)f
Divide both sides by the given wavelength
f = 2.78 * 10^14 seconds

The net force on an object that is accelerating at a rate of 4 m/sec is 255 N. What is the mass of the object in kg?
aleksklad [387]

Answer:

Given - acc = 4 m/ s^2

Force = 255 N

To find = mass

Solution -

Using the formula,

f = m \times a

255 = Mass × 4

255 /4 = Mass

63.75 = Mass

1 N = kg m/s^2

63.75 kg = Mass

Z is a covalent substance. In an experiment, a sample of pure solid Z was continually heated for 11 minutes
11111nata11111 [884]

When a pure solid Z sample it a covalent compound is heated continually for 11 minutes it will undergo disintegration leaving the bonds intact.

<h3>What is a covalent compound?</h3>

A covalent compound is a compound that is made up of molecules which share one or more pairs of valence electrons and are bonded together by a covalent bond.

One of the major factors that affect compounds with covalent bonds is temperature.

The increase in temperature during heating leads to the separation of the atoms from each other but leaving the bonds intact.
