The two objects that I would select to hang on the hook are scissors and stainless-steel cup.
<h3>The concept of Balanced Forces</h3>
Force symmetry
Balanced forces are those that have opposing directions and equal sizes. One definition of equilibrium is a state of balanced forces.
When the forces are in balance, there is no change in direction.
The sum of balanced forces is always zero. Merging vectors
The momentum or direction of an object cannot be changed by balance forces.
A balanced force keeps an object moving at a steady speed. (Newton’s First Law of Motion)
<h3>The Concept of unbalanced forces</h3>
Asymmetry of forces
Forces that are not equal in size and differ in direction, always set something moving. (Can alter an object’s direction or speed)
The combined force is equal to the difference between two unbalanced forces acting in opposing directions.
The combined force is equal to the sum of the two unbalanced forces acting in the same direction.
The net force is equal to the resultant when the forces are at right angles.

Answer: Radiation
Explanation:
The heat transfer process that is important in the transfer of energy from the Sun to Earth is Radiation.
Radiation is one of the mode of heat transfer which transfer energy/heat from one medium to another without any intervening medium. For example, heat from the sun reaches the earth through radiation. The sun hits the earth directly without any medium between the sun itself and the earth.
Answer:
Power = 47.0 Watt
Explanation:
As we know that friction force is given by
now we have
m = 6.0 kg
now we have
now since we need to find the rate of work done by friction force
so we can say rate of work done is power due to friction force
so it is given as
Answer
Vernier caliper measure nearest to 0.01 mm.
If the correct reading of the experiment is 9.62 mm.
But you misread it and listed it as 8.62 mm.
This is Clearly the case of mistake in Accuracy.
Because the reading is wrong and answer is not accurate hence it is mistake in accuracy.
To Judge weather the reading is precise or not we should have a range where the result is acceptable but in the question no range is given. So, we cannot comment on precision.
