780 seconds, or 13 minutes.
In the future, please use proper capitalization. There's a significant difference in the meaning between mV and MV. One of them indicated millivolts while the other indicates megavolts. For this problem, I'll make the following assumptions about the values presented. They are:
Total energy = 1.4x10^11 Joules (J)
Current per flash = 30 Columbs (C)
Potential difference = 30 Mega Volts (MV)
First, let's determine the power discharged by each bolt. That would be the current multiplied by the voltage, so
30 C * 30x10^6 V = 9x10^8 CV = 9x10^8 J
Now that we know how many joules are dissipated per flash, let's determine how flashes are needed.
1.4x10^11 / 9x10^8 = 1.56E+02 = 156
Since each flash takes 5 seconds, that means that it will take about 5 * 156 = 780 seconds which is about 780/60 = 13 minutes.
The Answer Is : D. 20.0 cm
My Reason : These types of problems can all be solved using the lens or mirror equation.
1/20 +1/q= 1/10
q=20 cm
The image is formed behind the lens at 2f or the center of curvature.
It is real, inverted, and the same size as the object
Answer:
The length of the boomerang is 0.364 m
Explanation:
The moment of inertia is:
Where
md = 0.05 kg
mh = 0.12 kg
r = d/2 = 0.273/2 = 0.1365 m
The length of the boomerang is:
<span>3040. Pascals.
The density of olive oil is 0.911 g/cm^3 and the density of water is 1.000 g/cm^3.
To calculate the pressure of 1 cm of water,
1000 kg/m^3 * 9.8 m/s^2 * 0.01 m = 98.000 Pa
To calculate the pressure of 1 cm of olive oil
911 kg/m^3 * 9.8 m/s^2 * 0.01 m = 89.278 Pa
Now to calculate the pressure at the bottom of the container, simply add the products of how many cm of each fluid you have. So
21 * 98.000 Pa + 11 * 89.278 Pa = 2058 Pa + 982.058 Pa = 3040.058 Pa
So the pressure at the bottom of the container will be 3040. Pascals.</span>
