Answer:
A precipitation reaction is a reaction between two aqueous Solutions that results in the formation of a solid compound.
Explanation:
Answer : Yes, distance measurements based on the speed of light used for objects in space.
Explanation : A light year is measurement of distance that light travel in a one year.
In a one year light travels 9460000000000 kilometer.
We know that, speed of light is
and time is 31536000 seconds in 1 year
so, distance= speed of light X time
Now, the light year is
Example : The nearest star to earth is about 4.3 light year away.
b. food
c. energy
d. electronics
Answer:
food
Explanation:
B. 19.6 m/s
C. 4.9 m/s
D. 9.8 m/s
i just did the quiz and so the only 2 options that made logical sense would be B (19.6 m/s) or D (9.8 m/s) the reason someone could get confused between these two is because 19.6 divided by 2 is 9.8 m/s so for each second it will go down 9.8 m/s but since it wants to know the velocity it would be 19.6 m/s
hope this helps
b. induction.
c. static electricity.
d. friction.
Answer : The correct answer is- D) Friction.
There are three modes of charging, which are Conduction, induction, and friction.
The static electricity is produced due to the rubbing of one substance with another. This is called charing by friction.
Hence, the correct answer is friction as there is friction between carpet and the feet of person walking over it.
Walking across a carpet is an example of charge being transferred by friction. The answer is letter D. The carpet, which is at rest, will resist the motion cause by your walking. This resistive motion d the friction the carpet obtained from you and you from the carpet.
