Using Δh = q+w
under adiabatic conditions q = 0
w= 25joules
Δh= 25joules

Answer:

The change in internal energy will be 25 J.

Explanation:

Given that,

Work done = 25 J

Using first law of thermodynamics

The internal energy is sum of the heat and work done.

\Delta U= Q+ W

Where, \Delta U = Change in internal energy

Q =  heat

W = work done

In adiabatic process, the heat does not change, it remains constant.

So the heat Q = 0

Therefore, The change in internal energy will be

\Delta U=0+25 J

\Delta U= 25 J

Hence, The change in internal energy will be 25 J.

Five basket ball teams are playing in a tournament. The teams will play with each other only one time. How many games will be pl
77julia77 [94]

<em>Ten games</em> will be played.

The first team can be any one of 5 .  For each of those, the opponent can be any one of the other 4 .

Number of ways to pair them up = (5 x 4) = 20 ways .

<em>BUT</em> ... Whether the Reds play the Blues, or the Blues play the Reds, it's the SAME GAME.  Each possible game shows up twice in the list of 20 ways.  So there are really only 10 different pairs ==> <em>10 games</em> .

A group of bike riders took a 4 hour trip. During the first 3 hours, they traveled a total of 50 km, but
zlopas [31]

Answer:

15km/hr

Explanation:

The average speed for the entire trip is the sum of the total distance traveled divided by the total time of the trip.

Total time  = 4hr

distance for the first 3hrs  = 50km

distance for the last 1hr  = 10km

  Total distance  = 50km + 10km  = 60km

Now;

  Average speed  = \frac{total distance }{time taken}  

 Insert the parameters and solve;

 Average speed  = \frac{60km}{4hr}   = 15km/hr

Describe the magnetic field when two unlike magnet poles are close together
MrMuchimi

A Magnet is an object that produces a Magnetic Field; it can be formed of a permanent magnet or an electromagnet. The word magnet comes from the Greek "magnítis líthos", which means "Magnesian Stone". Magnesia is an area in Greece (Now Manisa, Turkey) where deposits of magnetite have been discovered since antiquity.

Magnets come in many shapes but no matter what their shapes are, each magnet has a North Pole and a South Pole.

A Magnetic Field is said to exist in a region if a (Magnetic) Force can be exerted on a Magnet. Magnetic Field Lines (Flux Lines) are imaginary lines representing the direction and strength of the Magnetic Field. They go from the North Pole to the South Pole outside the Magnet, and go from the South Pole to the North Pole inside the Magnet. The density of the Magnetic Field Lines is higher near the Poles, and the Magnetic Force is stronger there.
