Sadly, I can't remember the name of who's 'Law' this is
in Electricity and Magnetism, but it says that the net
flux passing through a closed surface is equal to the
net charge inside.
In the picture, the net charge inside the surface is ( + q - q ) = Zero.
So it must follow, as the night follows the day, the net flux
through the surface is Zero. (D)
Answer:
Explanation:
Given
mass of sailboat 16300 kg
Eastward Force=17300 N
Northwest Force=59000
Resultant Force F is given by vector addition of two
|F| gives resultant magnitude
|F|=48340.48 N
therefore acceleration is given by
The increase in temperature of the water is
The total mass of the water is the product between its volume and its density
And so we can find the amount of heat released by the pebble to the water, because this is equal to the amount of heat absorbed by the water, which is
Answer:
The black body temperature of Earth T_e= 180.4 K
Explanation:
Assuming we have to find Black body temperature of the earth.
S0= solar energy striking the earth= 343 Wm^{-2}
\alpaha = 30% = 0.3
\sigma = stephan boltsman constant.= 5.67×10^{-8} Wm^{-2}K^4
T_e= 180.4 K
