Answer:
Nuclear Forces
Explanation:
Because strong nuclear forces work best within shorter distance.
Explanation:
This due to thermal insulation of some of the roof.
An insulator is body is a poor conductor of heat and will require high thermal energy to cause temperature changes.
- A house with a roof that is thermally insulated will have poor heat conduction.
- Since little heat is conducted, there wont be enough thermal energy to melt the snow.
- Thermal energy is directly related to heat.
- A house that is not insulated will absorb a lot of heat.
- This will cause the snow to melt very fast.

The relationship between wavelength, speed and frequency of a wave is given by

where

is the wavelength
v the speed
f the frequency
For the first wave, we can write

while for the second wave

where v is the same for two waves, since they have same speed. The first wave has twice the frequency of the second, so

So we can rewrite the wavelength of the first wave as

which means that the correct answer is
<span>3. the first has half the wavelength of the second</span>

Answer:
y = 6
Explanation:
Given parameters:
Given equation:
y = 2x + 10
And supposing; x = -2
Unknown:
y = ?
Solution:
We are going to solve this problem by substitution;
y = 2x + 10
since x = -2; input this into the equation to solve for y;
y = 2(-2) + 10 = -4 + 10 = 6
The value of y = 6
