Coulomb's Law: Force = k x q1x q2 divided distance square
where k=9x10^9 , q1 and q2 are the charge
So if you distance is halved, your force is stronger by 4 times
and if you distance is doubled, your force is 1/4
Ask me again if you aren't clear :)
Answer:
D. Asthenosphere
Explanation:
The asthenosphere is relatively plastic part of the mantle which underlies the brittle lithosphere. In the asthenosphere, it is generally believed that the rocks are in ductile state and easily moves. It is the site of convection within the earth. In mantle convection, hot and light materials rises and keeps moving into upper crustal levels till they solidify. Here also, cold and denser materials sinks deeper till they turn to melt. This differences in temperature and density sets up a convective cell within the mantle. Several convective cells are in the mantle.
It is an example of personification because personification is when human traits are give to non human things. Sky's cannot cry.
Explanation:
Given that,
Current of clothes dryer, I = 16 A
Voltage, V = 240 V
Time, t = 45 min = 2700 s
Current of personal computer, I' = 2.7 A
Voltage, V' = 120 C
Energy used by clothes dryer is given by :
Let t' is the time for this computer to "surf" the internet. Again using formula of energy used as :
So, for 8.83 hours you could use this computer to "surf" the internet.
Answer:
Explanation:
Flux Φ = nBA sinωt
t = 0 , flux = 0
dΦ / dt = nωBA Cosωt
e = nωBA Cosωt
= 100 x 2πx80 x.3 x .003 cos 2πx80 x .014
= 45.21 cos 7.0336
= 33.0668 v
= 33.1 V
