Answer:
Entropy of the universe is constantly increasing.
Explanation:
Entropy is the loss of available energy when it is in transit. The entropy of a system increases consuming the energy, this energy is now unavailable for doing the work or making the corresponding changes in the property of a system.
Entropy is the measure of randomness of a system. It is a toll that the nature takes for energy in transit.
The second law of thermodynamics concludes that all the energy cannot be transformed from one form to another and the flow of energy has a specific direction.
If a reversible process occurs, there is no net change in entropy. In an irreversible process, entropy always increases, so the change in entropy is positive. The total entropy of the universe is continuously increasing.
The answer is C.89,866. I multiplied 262x343.
A light-year is a unit of distance.
The definition of a light-year is the distance light travels in one year.
Answer: Part(a)=0.041 secs, Part(b)=0.041 secs
Explanation: Firstly we assume that only the gravitational acceleration is acting on the basket ball player i.e. there is no air friction
now we know that
a=-9.81 m/s^2 ( negative because it is pulling the player downwards)
we also know that
s=76 cm= 0.76 m ( maximum s)
using kinetic equation
where v is final velocity which is zero at max height and u is it initial
hence
now we can find time in the 15 cm ascent
using quadratic formula
t=0.0409 sec
the answer for the part b will be the same
To find the answer for the part b we can find the velocity at 15 cm height similarly using
where s=0.76-0.15
as the player has traveled the above distance to reach 15cm to the bottom
when the player reaches the bottom it has the same velocity with which it started which is 3.861
hence the time required to reach the bottom 15cm is
t=0.0409
Answer:
Open
Explanation:
A switch is a part of a circuit where a connection can be made or broken. By convention, when the switch is "open", the connection is broken and current cannot pass. When the switch is "closed", the connection is complete and current can pass.
