Answer: More work will be done in case A
Explanation:
Work is said to be done when a force applied to an object causes the object to move through a distance or height.
Work = Force × distance
If the heavy load is pulled straight up with a massless rope, then the object is pulled through a height at an angle perpendicular to the ground (i.e 90°)
Much work will be done in case A and less work in case B. Less work is done in case B due to the use of a machine which is an inclined plane. The use of machine makes work much easier and it allows us to do work in a more convenient manner. It allow us to overcome a much larger load using minimal effort. For the first case, much work will be done since we are carrying through a vertical height which requires more effort compare to when an inclined plane is used.
Also note that the higher the angle of inclination, the more the work done on the object and vice versa
Answer:
the lawyer should Inform Mr. X through that Tax attorney and ABC management to get approval.
Explanation:
According to my research on different lawyer proceedings, I can say that based on the information provided within the question before taking Paula's Case the lawyer should Inform Mr. X through that Tax attorney and ABC management to get approval. This can be said because since both Mr.X and Paula are clients of the law firm, there may be a breach in confidentiality if the lawyer decides to take Paula's case. Therefore he needs to talk to everyone involved and place restrictions if the case is taken.

Answer:
Conduction is fastest in solid
Explanation:
A basic property of conduction is that for heat to transfer there must be contact. From kinetic theory, configuration of solid is such that the molecules are held together and they move or vibrate about their mean position. Because of this arrangement heat transfer by conduction is faster in solid that any other state of matter
Explanation:
It is given that,
The velocity of a particle is given by :
Where
v is in m/s and t is in seconds
Let a is the acceleration of the object at time t. So,
When a = 0
t = 2.5 s
a is zero at t = 2.5 s. Velocity,
v = -75 m/s
Since, , s is the distance travelled
At t = 2.5 s,
s = −83.34 m
Hence, this is the required solution.
Your question should includes how much energy does the battery deliver in 80 hours interval.
Answer:
The battery delivers 17,280 J
Explanation:
Starting voltage v1 = 9V
Final voltage v2 = 6V = voltage drop after 80hrs
v = v1 - v2 = 9 - 6 = 3V
Electrical current (i) = 20[mA] = 20*10^-3 A
Discharging time = 80 Hrs = 80*(60*60) sec = 288,000 sec
Work done = energy (W) = p.t
Where p = v*i
W = v*i*t
W = 3*(20*10^-3)*288,000
W = 17,280 J
The battery delivers 17,280 J
