When objects are dipped in water, they move aside (displace) some water. This is how they make room for themselves.The volume of water displaced = the volume of the objectThis volu...

Is it the current or the voltage that kills from a deadly electric shock?It s a long disputed question which many people don t understand fully. Some think it s the voltage, wh...

Have you ever Wandered why objects of different masses fall at the same rate? Me too! It turns out it s a really interesting phenomenon. A video taken by NASA astronauts on the moon...

Read the question. Do you understand what the question is asking, and the format of answer required?A ball is dropped from rest and falls 5 m to the ground. What is the speed of the b...

The uncertainty can be expressed as a percentage of the reading. Percentage uncertainty = uncertainty /(average value) x 100%Example. A metre rule that measures a block as 295 mm ha...

AbstractStudies on surface wettability have received tremendous interest due to their potentialapplications in research and industrial processes. One of the strategies to tune surface...
