The net force = sum of all forces acting on the body
If we take left side as -ve and right side as +ve,
then,
The net force here would be equal to,
10N + (- 3N)
= 7N.
Therefore, a net force of +7N ( + indicates it's moving towards right) is acting on the book of mass 2kg.
'A' is correct. B, C, and D are false statements.
The mechanical advantage of the screwdriver that is being described above is equal to 75N. This means that for every 30N that is applied on the screwdriver, this simple machine would in turn apply 75N of force to the lid of the can.
Answer:
Explanation:
Speed and medium are properties of a wave which is in common within an area of the spectrum of visible light. i.e;
Their medium of propagation
They both travel at the same speed ( speed of light )
The properties mentioned above are properties that define that wave is found within an area spectrum for visible light.
