Making a drawing of the system, we will have two forces which are tension and the weight of the object. Balancing the forces present, we do as follows:
T = W
W = 30 N
Therefore, weight is equal to 30 N. Hope this answers the question. Have a nice day. Feel free to ask more questions.
#3). The wavelengths of the four types of electromagnetic
radiation on that list line up like this:
Longest ... microwaves
next . . . . . infrared waves
next . . . . . visible light waves
shortest ... ultraviolet waves
#4). The word "visible" means "able to be seen". Infrared
light and ultraviolet light are not visible to human eyes.
The feathers act as a thermal insulator as they trap your body heat inside of you and trap the cold outside of your duvet.
Answer:
6 m/s
Explanation:
momentum= mass times velocity
120 = 20v
v = 120/20
Answer:
It depends on the ratio of nuetrons to protons
