Answer:
t=27725.8minutes
Explanation:
To determinate use the law the change of volume in determinate time is derivate so:
The flow in is zero and the flow out is modeling with V as the volume out in the volume of the lake in the reason of change.
Integrate to get the volume function
The find the constant C in the time t=0 the volume is knowing so:
The volume is 1 part per million so:
Answer:
Clara has speed of 80m/min
Explanation:
Clara was jogging at 600 m in 5 minutes. She stopped suddenly which reduced her velocity and then she waited for 10 minutes so that her friends comes near her. She stopped to catch her friend. During this 10 minutes the velocity of Clara is zero. She started to walk again at a slower speed of 80m/min.
This is very good conceptual question and can clear your doubts regarding work-energy theorem.
Whenever force is perpendicular to the direction of the motion, work done by that force is zero.
According to work-energy theorem,
Work done by all the force = change in kinetic energy.
here, work done = 0.
Therefore,
0=change in kinetic energy
This means kinetic energy remains constant.

Hey There!
The atomic number represents the electrons and protons, therefore, if the atomic number of the element is 7 then there are 7 electrons and protons in the element.
In order to determine the amount of neutrons, you would subtract the atomic number from the atomic mass.
Hope this helped!
The distance is 28 meters and the direction of displacement is East I think
