Time is an illusion time is the progression of from the past to the present into the future.
The total money that will be present in the bank account, disregarding the percent rate of money increase is the sum of the initial deposit and the all the amounts deposited for m months, 25m. Thus, the answer should be,
T = 10 + 25m
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.

Answer:
0.853 m/s
Explanation:
Total energy stored in the spring = Total kinetic energy of the masses.
1/2ke² = 1/2m'v².................... Equation 1
Where k = spring constant of the spring, e = extension, m' = total mass, v = speed of the masses.
make v the subject of the equation,
v = e[√(k/m')].................... Equation 2
Given: e = 39 cm = 0.39 m, m' = 0.4+0.4 = 0.8 kg, k = 1.75 N/cm = 175 N/m.
Substitute into equation 2
v = 0.39[√(1.75/0.8)
v = 0.39[2.1875]
v = 0.853 m/s
Hence the speed of each mass = 0.853 m/s
