Answer: type of force is friction
Explanation:
Answer:
the horizontal force acting on rod is - 25.909 N
veritical force is 25.48 N
Explanation:
Given data:
mass of rod is m 2.6 kg
length of rod is 1.5 m
Hinge distance from the wire is 0.70 m
Apply torque law about hinge
Tension in the wire is
= -25.909 N
the horizontal force acting on rod is
Fx = T
FX = - 25.909 N
vertical force is
Fy = mg
Answer:
at the same time as the light object
Explanation:
vacuum is a region with a gaseous pressure much less than atmospheric pressure.
In a vacuum, gravity causes all objects to fall at the same rate. The mass of the object does not matter. If I drop for example a heavy stone and a light stone, air will make the light stone fall more slowly. But if there were no air, they would fall at the same rate.
So, When an object falls with air resistance, both its rate of fall and speed change during its motion. When an object falls in a vacuum, there is no air resistance because there is no air in a vacuum.
Answer: Option (C) is the correct answer.
Explanation:
Whether an acid is weak or strong it will cause harm if it comes in direct contact with the skin, eyes or mouth etc.
Thus, in order to prevent oneself, it is advised to wear a lab coat while working in laboratory as acids break down fabrics and can cause burns if the acids are strong.
Hence, a lab coat acts as a protective layer on the clothes so that even if acid falls on it then it might not reach the skin immediately and on time prevention can be taken.
