Answer:

Explanation:

electron rest mass = 0.511MeV/C²

postion rest mass = 0.511MeV/C²

boson rest mass = 91.188GeV/C²

= 91188 MeV/C²

A stationary 15 kg object is located in a table near the surface of the earth. The coefficient of static friction between the su
madreJ [45]

maximum static friction acting on the object will be

F_s = \mu_s mg

plug in all values

F_s = 0.40 \times 15 \times 9.8 = 58.8 N

So here it means that if applied force is less than or equal to 58.8 N then the object will remain stationary as friction can balance the external force upto this limit of external force

So here it is given that applied force is 20 N

so here object will not move due to this force and it will remain at rest always

due to this applied force

A train's mass is 500 kg and it's acceleration is 5 m/s. What is the net force on the train
trapecia [35]
The answer is 2500 newtons. F = M * A, so 500 kg x 5 m/s = 2500 newtons.
