Answer:
This equation shows the relationship between speed, distance traveled and time taken: Speed is distance divided by the time taken. For example, a car travels 30 kilometers in 2 hours. Its speed is 30 ÷ 2 = 15km/hr.
Explanation:
For example, a car travels 30 kilometers in 2 hours. Its speed is 30 ÷ 2 = 15km/hr.
Answer:
1. Speed is a measure of how quickly an object moves from one place to another. It is equal to the distance traveled divided by the time. ... To find the speed, distance is over time in the triangle, so speed is distance divided by time. To find distance, speed is beside time, so distance is speed multiplied by time.
SPEED= DISTANCE/TIME
2. Mantle convection - The rocky mantle of the Earth moves slowly because of the convection currents that transfer heat from the interior of the Earth up to the surface.
Gravitational convection - Because fresh water is buoyant in salt water, dry salt diffuses downward into wet soil.
3. Symbiosis is the phenomenon by which two organisms maintain relationship with each other to be mutually benefitted. In symbiotic mode, organisms develop a special relationship with certain other organisms to obtain nourishment. Organisms involved in this type of relationship are called as symbionts.
e.g. Rhizobium bacteria and Leguminous plants are symbionts exhibiting symbiosis.
4. Emulsification is defined as a process of dispersing one liquid (containing the bioactive compounds) in a second immiscible liquid, by applying electrostatic, or hydrophobic, or hydrogen bonding interactions between the bioactive compounds and an encapsulating material.
