Answer:
Explanation:
The magnitude of electric field = 8 x 10⁴ V /m
there is a potential difference of 8 x 10⁴ V on a separation of 1 m
so on a separation of .5 m , potential drop or change in potential will be equal to
.5 x 8 x 10⁴
= 4 x 10⁴ V .
The increase in kinetic energy of proton = V X Q
V is potential drop x Q is charge on proton
= 4 x 10⁴ x 1.6 x 10⁻¹⁹
= 6.4 x 10⁻¹⁵ J
potential energy of the proton-field system will be correspondingly decreased by the same amount or by an amount of
- 6.4 x 10⁻¹⁵ J .
1mL of coke cost =$0.00117.
The cost of 2-liter bottle of coke is $2.34
The unit of 1 liter is 1000ml.
Then the 2 liter coke bottle volume is 2000ml
The formula is ( divide the total price by the quantity).
$2.34/2000=0.00117.
The capacity of a liquid is measured in metric units of volume called liters and milliliters. There are four units of measurement for liquid volume: milliliters, centiliters, liters, and kiloliters. The values of these units vary even though they all refer to the same quantity.

Answer:
at location 4
Explanation:
it is because the solar eclipse happens when the moon is covering the sun
We can solve for the power dissipated by the oven on the given values of voltage which is 120 volts and current which is equal to 12.5 amperes.
The formula for Power dissipated is P=V*I where "v" for the voltage and "i" for the current.
P=120*12.5
P=1500 watts
The answer is 1500 watts.
Wavelength = speed / frequency.
Wavelength = 3x10^8 m/s / 30 hz
Wavelength = 10 million meters
1/2 wavelength = 5 million meters
(that's about 3,100 miles)
I'm pretty sure the frequency is wrong in the question.
I think it's actually 30 kHz, not 30 Hz.
That makes the antenna about 3.1 miles long.
