There are various properties which are exhibited by substances like physical properties,chemical properties,magnetic properties,electric properties etc.
By simply observing the substance we can not get any idea about the property of a substance.One has to conduct various tests in order to reach at his or her conclusion. The scientific tests provides a better understanding about the nature of substance and the changes that happen under various conditions and parameter.
Answer:
4.5 m/s
Explanation:
The rock must barely clear the shelf below, this means that the horizontal distance covered must be

while the vertical distance covered must be

The rock is thrown horizontally with velocity
, so we can rewrite the horizontal distance as

where t is the time of flight. Re-arranging the equation,
(1)
The vertical distance covered instead is

where we omit the term
since the initial vertical velocity is zero. From this equation,
(2)
Equating (1) and (2), we can solve the equation to find
:

The temperature of a gas in which the atoms are moving slowly is (THE COLD).
THAT'S IT! :)

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat, may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical
