Why is gravity weaker underwater? This is because water exerts a kind of frictional force called “force of buoyancy”. When you throw something into water , the water below the object will push it upwards making the object weigh less. Why is there no gravity under water? There is gravity everywhere. Gravity is just the […]
Are humans made of carbon-12?
Are humans made of carbon-12? The most important structural element, and the reason we are known as carbon-based life forms. About 12 per cent of your body’s atoms are carbon.

Is heat a scalar or vector quantity?
Is heat a scalar or vector quantity? Heat is an aggregate measure of the amount of energy stored in a system of particles (a single particle doesn’t have a temperature), but it doesn’t point in any particular direction, so it’s a scalar. What is a zero vector give an example? When the magnitude of a […]
What are 3 types of symbiosis?
What are 3 types of symbiosis? Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. There are three basic types of symbiosis: mutualism, commensalism, and parasitism.

What direction do surface winds move in the Northern Hemisphere?
What direction do surface winds move in the Northern Hemisphere? The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. The Coriolis effect causes some winds to travel along the edges of the high-pressure and low-pressure systems. Why is Coriolis effect different in Southern Hemisphere? The reverse […]
