Explanation:
The given data is as follows.
= 400 K, 
= 500 K,
= 25 kJ = 25000 J (as 1 kJ = 1000 J)
Now, we will calculate the change in entropy as follows.
Putting the given values into the above formula as follows.
= 
= 250 J/K
Hence, we can conclude that change in entropy is 250 J/K.
Answer:
yesssssssssssssssssssssssssssssssssssss
Answer:
605 J
Explanation:
Efficiency = work out / work in
0.78 = W / 775 J
W = 605 J
Answer:
F = 479.21 N
Explanation:
given,
initial velocity = 0 m/s
final velocity = 16.7 m/s
time taken = 20.7 s
combined mass of the boat and trailer = 594 kg
tension in the hitch = ?
using equation of motion
v = u + a t
16.7 = 0 + a × 20.7
a = 0.807 m/s²
Force = mass × acceleration
F = 594 × 0.807
F = 479.21 N
Hence, the tension in the hitch that connects the trailer to the car is F = 479.21 N
Answer:
Mass is how much "stuff" is in something. Weight is a force that is measured in Newtons. A pan balance is a type of scale. A measuring cup is used to measure volume, such as cups and grams (depending if you use the metric system or not).
