Friction can be defined as a type of force that prevents two smooth surfaces from sliding together on each other. Friction is a strong force that oposses motion when two surfaces come in contact with each other.
The different methods/ways to reduce friction include;
- Application of lubricant to surfaces
- Streamlined bodies; this goes a long way in preventing friction between two bodies.
- Decrease in weight; reducing the amount of weight on a substance can also help to reduce friction
- Applying wheels to objects that move/roll on the ground.
Explanation:
If the intensity of the yellow light increased, meaning more photons will strike the Potassium metal per unit area. This will cause more ejection of electrons from the metal and hence, the strength of current will also increase as we know that
I = Q/t, as the charge increase , the current will also increase.
Answer:
x = 58.86[mm]
Explanation:
This problem can be solved by means of Hooke's law which tells us that the force is equal to the product of the constant of the spring by the distance that is compressed or stretched. The following equation can be used.
where:
F = force or weight [N]
k = spring constant = 2*10⁵ [N/m]
x = distance compressed [m]
The weight can be calculated as the product of the mass by the gravity acceleration.
Now replacing in the Hook's law
You would record this as bonding
