The heat will leave the house, causing it to become colder. if it’s windy outside it will get colder in the house faster.
It’s half the mass of the object by its velocity ^2
Answer:
P.E = 13230 J
Explanation:
Given,
The mass of the rock, m = 45 Kg
The rock is sitting at a height from the ground, h = 30 m
The acceleration due to gravity, g = 9.8 m/s²
The potential energy of the body is given by the formula,
P.E = mgh joules
Substituting the given values in the above equation
P.E = 45 x 9.8 x 30
= 13230 J
Hence, the potential energy of the rock is P.E = 13230 J

Answer:
L = 7 [cm]
Explanation:
To solve this problem we must analyze each of the distances mentioned and take into account the number of covers and thicknesses of these.
The worm crosses through the sheets of the first book, this distance can be determined by the following length analysis.
4 = P + 2*C
Where:
P = thicknesses of the pages [cm]
C = thicknesses of each cover [cm]
P = 4 - 2*(0.5)
P = 3 [cm]
The distance crossed was:
L = P + 2C + P "the pages of the first book + 2 covers + the pages of the second book"
L = 3 + (2*0.5) + 3
L = 7 [cm]
