Explanation:
Answer a kind of radiation including visible light, radio waves,gamma rays,and x-rays,in which electric and magnetic fields vary simultaneously
Explanation:
Answer: 510 m/s
Explanation: specific gravity of steam is 18/29 = 0.620
It is the ratio of the density of steam over density of water
400m3/s of steam =
400m3ms * 0.620 of water
= 248m3/s of water
Total flow rate Q = 248 + 7 = 255m3/s
Using Q = AV
Where A is area and V is velocity
V = Q/A
V = 255/0.5 = 510m/s
As for me, the reson why scientists usually write reports about their investigations is because they want to <span>d. to communicate their work to other scientist. As far as I am concerned in this sphere they have to get many other opnions besides their own in order to complete or expand one that they have made up. Hope it helps :)</span>
<u>Answer:</u>
"Where friction or rubbing results in the transfer of electrons between particles, objects can become negatively or positively charged."
<u>Explanation:</u>
The motion resistance of one moving object with respect to another is called as "Friction". It isn't a basic force, like gravity or electromagnetism. Alternatively, scientists believe it is the product of the electromagnetic attraction in two touching surfaces between charged particles.
The friction have formula:
Friction force (<em>f </em>) = coefficient of friction × normal force (N)
For an instances when one ride a bicycle, an example of rolling friction is the contact between the wheel and the way.
