When a substance boils the molecules within the substance move faster and farther apart, meaning (depending on the current matter state of the substance) molecules will go into more liquid and gaseous states
solid----> liquid ----> gas
In the case of something boiling the substance goes from liquid to gas due to the increased molecular activity because to heat...
Mass is indirectly proportional to acceleration, so, lighter the object greater would be it's acceleration...
A) 0.10 kg is lightest among them, so it's your answer
Answer:
D
Explanation:
Ball A is a non positively charged non metal while ball B is metal ball.
Given: The ball B positive charge of small magnitude
To prove: Balls will attract each other
IN this condition because of induction negative charges on the sphere B move to the side closer to sphere A,(induction charging) while the positive charges move to the side further away from sphere A. The polarization of charge on B will cause a greater attractive force than the repulsion of the like charges.
Hence the correct answer will be D .
Simple reaction time involves selecting a
specific and correct response from several choices when presented with several
different stimuli. This is very important because historically, this was the
first indicators of intelligence pioneered by Francis Galton. To measure one’s
intelligence is to know how he quick a person could respond to the stimulus
with an already expected response wherein the stimulus is given unknown to the
receiver. In other terms, the intelligence is measured on how quick a person
could grasp certain concepts and how he could think fast and answer them
correctly.

Answer:
The magnitude of the acceleration is 
The direction is 
north of east
Explanation:
From the question we are told that
The force exerted by the wind is 
The force exerted by water is 
The mass of the boat(+ crew) is 
Now Force is mathematically represented as
Now the acceleration towards the north is mathematically represented as
substituting values
Now the acceleration towards the east is mathematically represented as
substituting values
The resultant acceleration is
substituting values
The direction with reference from the north is evaluated as
