Obtaining the component part of the letter 'i' warns that it is the velocity is oriented on the X axis. At the same time the numeric part, in this particular case will represent the scalar part and therefore the magnitude of the vector.
The velocity is

The vector component of the velocity is

The scalar component of the velocity is

The magnitude of the velocity is

Answer:
1.67×10^-11 N
Explanation:
m1 = 0.13kg
m2 = 0.34kg
d = 0.42m
G = 6.674 × 10 ^−11
F = Gm1m2/r²
F= (6.674 × 10^ −11×0.13×0.34)/(0.42)²
F = 1.67×10^-11 N
Answer:
Kristine is correct
Explanation:
this is because when an ice cube is placed into the warm water, it absorbs the heat from the water in order to melt which lowers the water's temperature.
in Eric's case, a hot cup of tea does not lose its heat because of cold hands. it varies depending on the cup whether it is a good insulator or not. also the heat can be lost through the air as well.
Answer: Option (c) is the correct answer.
Explanation:
The difference in electrical potential energy between two places in an electric field is known as potential difference.
Mathematically, potential difference between two given points can be written as follows.

where,
= potential difference
= potential at point 1
= potential at point 2
