Answer:
221754385964.9123
Explanation:
Convert miles to nanometer
1 mile = 1.6 km
1 km = 1×10³×10³×10³×10³ nm
1 mile = 1.6×10¹² nm
So,
158 miles = 158×1.6×10¹² = 252.8×10¹² nm
Length of each molecule = 1140 nm
Number of molecules = Total length / Length of each molecule
There are 221754385964.9123 number of molecules in a stretch of 158 miles
1. Power.
Power is the rate of energy transfer or the rate at which work is done.
2. watt
Power=energy or work done/time=1 J/1s=1 watt (w)
3. Current times the voltage
E=QV
Q=I times t
E=VIt
p=E/t
p=VIt/t
p=VI
4.200 watts
p=VI=40 x 5=200 W
5. Amount of power available is significantly greater.
p=VI
When V increases, I must go down at the same time so that p doesn’t increase.
Since I is decreased, the power losses due to joule’s heating effect is decreased. The equation representing the energy loss for joule’s heating effect is:
E=I^2Rt
As I is decreased, the energy loss also decreases. Power=energy transferred/time and so as the energy loss due to Joule’s heating effect is decreased, the power loss is also decreased.
Hello!
We can use Faraday's Law of Electromagnetic Induction to solve.
ε = Induced emf (4.08 V)
N = Number of loops (?)
= Magnetic Flux (Wb)
t = time (s)
**Note: The negative sign can be disregarded for this situation. The sign simply shows how the induced emf OPPOSES the current.
Now, we know that is analogous to the change in magnetic flux over change in time, or , so:
Rearrange the equation to solve for 'N'.
Plug in the given values to solve.
**Rounding up because we cannot have a part of a loop.
Answer:
"Greek Origins" were the first philosophers to propose that atoms existed.
Explanation:
The idea that all matter is made up of tiny, indivisible particles, or atoms, is believed to have originated with the Greek philosopher Leucippus of Miletus and his student Democritus of Abdera in the 5th century B.C. (The word atom comes from the Greek word atomos, which means “indivisible.”)
