Calculate the value of two equal charges if they repel one another with a force of 10 n having 10 m distance apart in a vacuum. what would be the size of the charges if they were situated in an insulting liquid whose permittivity was ten times that of a vacuum.

An air bubble of volume 20 cm³ is at the bottom of a lake 40 m deep, where the temperature is 4.0°c. the bubble rises to the surface, which is at a temperature of 20°c.take the temperature of the bubble’s air to be the same as that of the surrounding water. just as the bubble reaches the surface, what is its volume?

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce
