Answer: 43s
Explanation:
The stored energy across a plate can be measured by calculating the electric charge and the potential difference. Also, the quantity of electricity can be measured by multiplying the current in the circuit with the time taken.
Given
Potential difference, V = 120 v
Current, I = 11.5 A
Energy, E = 59 kJ
Remember,
E = QV, so that
Q = E/V
Q = 59000/120
Q = 491.67 C
Q = IT
491.67 = 11.5*t
t = 491.67/11.5
t = 42.75s ~ 43s
Time taken to cook the 3 hot dogs simultaneously is 43s
<span>If you can't measure the parallax that means that the star is far far away, beyond all possible reach of humanity with its current technology. The closer the star is the greater the parallax, so you either get a bigger, more powerful telescope, or you just accept that it's too far away to be measured at all. Eventually the technology will develop enough to measure it.</span>
A. Any Direction
This should be obvious, as you can push down on something, push it to the sides, and push something up. Hope this helped!
Answer:
r₂/r₁ = 1.82
Explanation:
The electric field due to a point charge, has the following expression:
For a distance r₁, the magnitude of the electric field is 395 N/C, so we can solve for r₁², as follows:
r₁² = 
(1)
For a distance r2, the magnitude of the electric field is 119 N/C, so we can solve for r₂², as follows:
r₂² = 
We can find the quotient r₂/r₁, from (1) and (2):
r₂/r₁ =
= 1.82
