Because you would fall so slow that you would not need one.
The correct answer is - a. was a sign of danger.
Once the people saw that the ocean waters are receding and were living vast space without water behind them, they knew that something big and very dangerous will happen. And in fact it did. The water that was sucked in in the place were there was a crack on the ocean floor, got shot back under big pressure and it had very big speed, as well as having waves that were destroying anything on their way.
Answer:
Charge of particle 2, 
Explanation:
Given that,
Charge 1, 
The distance between charges, r = 0.241 m
Force experienced by particle 1, F = 3.44 N
We need to find the magnitude of electric charge 2. It can be calculated using formula of electrostatic force. It is given by :
or
So, the magnitude of electric charge 2 is . Since, the force is attractive then the magnitude of charge 2 must be negative.
Answer:
in salt water
Explanation:
The buoyant force acting on a body depends on the volume of body immersed, density of liquid in which the body is immersed and acceleration due to gravity.
Buoyant force = Volume immersed x density of liquid x g
As the density of salt water is more than the fresh water so the buoyant force acting on the boat in salt water is more than the fresh water.
