Using Dimension Analysis notation (where length is represented by [L], mass by [M], and time by [T), and constants are ignored), what are the dimensions of the following:
a. A distance of 987 km
1
b. A distance of 3 m
C. A speed of v = 30 m/s
d. A Kinetic Energy (72 m v?) of 5 Joules (The Joule is a unit of energy)
An acceleration of 3m/s/s
e.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

temp rises, and expansion

find the sum of the two horizontal vectors and the sum of the two vertical vectors

god i hope this !
