Answer:

2.3)X10^13-Hz

Explanation:

What’s the frequency of radiation that has a wavelength of 13 um, about the size of bacterium?

a micro meter is 10^-6 meter

frequency of light times wavelength = c  the speed of light 3X10^8 M/sec

so

frequency times 13 X10^-6 =3X10^8  M/

so

FR3EQUENCY = 3X10^8/13X10-6

=(30/13)10^13 =2.3)X10^13-Hz

What is the difference between mass and weight?
Olin [163]

Explanation:

The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.

The Chemistry Cafe was out of bread. The cook went next door to the bakery and bought a loaf of bread which has 33 slices. Then,
maria [59]

In the question, we are told that there are;

  • A loaf containing 33 slices
  • A loaf containing 33 slices A package of cheese containing 15 slices

We also know that he is making a sandwich that has 2 pieces of both cheese and bread.

Hence;

Total number of bread and cheese = 33 + 15.

Each loaf should have two pieces of each bread and the cheeses make a total of four pieces.

Therefore he can make = 33 + 15/4 = 12 sandwiches.
