Darker colors absorb heat, While lighter colors don't. If a house is painted black in Arizona, The black color will absorb the heat making the temperature inside the house very hot even with the AC on. If a house in Arizona is painted White, The heat will bounce off the White color, making the temperature inside the house cooler.
Hope this helps!

2) Frequency - It is the number of waves cycles per unit of time, passing a
point per unit time. It is usually measured in Hertz.</span>
Answer:
1.336 m
Explanation:
q = - 3.77 micro C at y = 0 m
Q = - 4.92 micro C at y = 2.86176 m
Let the electric field is zero at P which is at a distance y from origin.
Electric field at P due to q is equal to the electric field at P due to Q.
2.86176 - y = 1.142 y
2.142 y = 2.86176
y = 1.336 m
Thus, the electric field is zero at y = 1.336 m.
Answer:
Ep = 3704.4 J
Explanation:
Data:
- Mass (m) = 126 kg
- Gravity (g) = 9.8 m/s²
- Height (h) = 3 m
- Potential Energy (Ep) = ?
Use formula:
Replace:
- Ep = 126 kg * 9.8 m/s² * 3 m
Multiply, but it tells us that the units should not be used in the answer, so we solve it as follows:
What is the GPE?
The GPE is <u>3704.4 Joules.</u>
Answer:
3.0m
Explanation:
Because the image distance(v) =object distance(u)
v+u=1.5+1.5=3.0m
