The answer should be B.
The greenhouse effect is when the sun gives us the heat and since global warming is putting too much carbon dioxide into our atmosphere the heat won't be able to leave the atmosphere. Or at least most of it wont be able to leave.
Have a nice day!!!
Answer:A powder is an assembly of dry particles dispersed in air. If two different powders are mixed perfectly, theoretically, three types of powder.

Answer:
q_enclosed = 759.57 nC
Explanation:
A cylindrical shell of radius 7.00 cm and length 2.48 m has its charge uniformly distributed on its curved surface. The magnitude of the electric field at a point 15.3 cm radially outward from its axis (measured from the midpoint of the shell) is 36.0 kN/C.
Find the value of the net charge on the shell.
Given that Length L of the cylinder shell is 248 cm and the diameter d is 7.0 cm. We can approximate L >> d. This approximation concludes that the cylindrical shell is infinitely long, when we are examining the Electric fiel strength E from the ends of the shell.
Hence,
E = q_enclosed / 2*pi*ε_o *r*l
Where r = d / 2, then
q_enclosed = E*(2*π*r*l*ε_o)
q_enclosed = (36000)*(2*π*8.85*10^-12 *0.153*2.48)
q_enclosed = 759.57 nC
Answer:
a.3.20m
b.0.45cm
Explanation:
a. Equation for minima is defined as:
Given , and :
#Substitute our variable values in the minima equation to obtain :
#draw a triangle to find the relationship between and .
#where
Hence the screen is 3.20m from the split.
b. To find the closest minima for green(the fourth min will give you the smallest distance)
#Like with a above, the minima equation will be defined as:
, where given that it's the minima with the smallest distance.
#we then use to calculate =4.5cm
Then from the equation subtract from :
Hence, the distance is 0.45cm
<span>1 represents condensation and 2 represents precipitation.
During the condensation, the water that rise through evaporation will be transformed into liquid form.
During the precipitation, this liquid form will fall to the ground because of gravity, and created what we commonly known as the rain</span>
