What fossilized fern was found in Africa Australia and South America? Glossopteris fossil What is a Glossopteris fossil? Glossopteris, genus of fossilized woody plants known from rocks that have been dated to the Permian and Triassic periods (roughly 300 to 200 million years ago), deposited on the southern supercontinent of Gondwana. Glossopteris occurred in a […]
Does fog increase temperature?
Does fog increase temperature? Fog often dissipates with daylight. This is sometimes referred to as the fog “burning off” but that analogy is not correct. When the sun rises, the air and ground warm up. This leads to the air temperature being warmer than the dew point temperature, which causes the fog droplets to evaporate. […]

What goes on a kinetic diagram?
What goes on a kinetic diagram? A Kinetic Diagram is a diagram that represents the acceleration vector of Newton’s Second Law, or the right hand side of the F = ma equation. On a kinetic diagram, you draw the direction and magnitude of the mass times acceleration component of the body you have isolated. How […]
Why pull up and pull down resistors are used?
Why pull up and pull down resistors are used? Pull-up resistors are resistors used in logic circuits to ensure a well-defined logical level at a pin under all conditions. Pull-up resistors are used to solve the dilemma for the microcontroller by pulling the value to a logical high state, as seen in the figure. Why […]
What are the steps of muscle contraction?
What are the steps of muscle contraction? The process of muscular contraction occurs over a number of key steps, including: Depolarisation and calcium ion release. Actin and myosin cross-bridge formation. Sliding mechanism of actin and myosin filaments. Sarcomere shortening (muscle contraction) What are the two main types of muscle contraction? Isotonic contractions – these occur […]

Why gravitational potential energy is always negative?
Why gravitational potential energy is always negative? Gravitational potential energy is negative at the surface of Earth, because work is done by the gravitational field in bringing a mass from infinity i.e work has to be done on a body, if it is taken away from the gravitational field of the earth. Thus, potential energy […]
