Answer:
The answer is 0.00005 meters
Explanation:
In order to determine the diameter in meters, you have to know the meaning of the unit [um]. This unit is called "micrometer" and its value is 
m.
Then, we change the [um] unit into its expanding form:
50 um=
Finally, the diameter in meters is 0.00005 meters.
For part 2 number 1:
first multiply 3.0 by 20 to get 60. Then multiply 3.0 y 10 to get 30. Add both answers together to get 90. The answer is 90 meters per second squared.
Answer:
Option D is the correct answer: The model allows us to predict how atoms will behave in certain situations.
Answer:
A. he can hear music coming from the radio.
Explanation:
Jeff knows that the radio produces sound energy because he can hear music coming from the radio.
The music from the radio is a form of sound energy.
- Sound energy is a form of energy dissipated from a body and can be discerned by humans.
- Sound is a mechanical wave that requires a material medium for its propagation.
- It travels by series of rarefaction and compression along its path of motion.
- Since sound energy is an energy in motion, it is a kinetic energy.
- It travels parallel to its source and therefore, it is a longitudinal wave.
Sum of the first ten digits is:
7+3+4+5+4+1+7+8+0 = 39
39, when divided by 9 give you the remainder of 3
9 x4, is 36
36 +3 equals 39
(39 = 9 x 4 + 3)
So X= 0
