What is relation between force and area? When a force is exerted on an object it can change the object’s speed, direction of movement or shape. Pressure is a measure of how much force is acting upon an area. Pressure can be found using the equation pressure = force / area. Therefore, a force acting […]
Why is Ram of chlorine not a whole number?
Why is Ram of chlorine not a whole number? Answer: The reason for the atomic mass of chlorine taken as 35.5u and not as 35u because of the presence of isotopes.

What affects the magnitude of EMF?
What affects the magnitude of EMF? The magnitude of the induced current depends on the rate of change of magnetic flux or the rate of cutting of the magnetic field lines. What are the factors affecting the emf of a cell? E.m.f. of a cell depends upon the material of electrodes and electrolyte used in […]
Is humidity wet or dry?
Is humidity wet or dry? The humidity scale is measured on a scale 0 to 100 since it is a percentage. When humidity reaches 100%, condensation occurs. At 0%, the air would be extremely dry. To compare the amount water vapour in the air, it is important to consider both the humidity and temperature. How […]
Why do veins carry blood at low pressure?
Why do veins carry blood at low pressure? The walls of veins have the same three layers as the arteries. Although all the layers are present, there is less smooth muscle and connective tissue. This makes the walls of veins thinner than those of arteries, which is related to the fact that blood in the […]
