Answer:
joules</h2>
Explanation:
From the first law of thermodynamics,
Δ
=Δ
+
Where is the heat given to the gas,
is the internal energy of the gas,
is the workdone by the gas.
When pressure is constant,
When pressure is constant,
Δ
Where 
is pressure and is the volume of the gas.
Given 
Δ
So,
Given that Δ
So,Δ
Answer
given.
Mass of big fish = 15 Kg
speed of big fish = 1.10 m/s
mass of the small fish = 4.50 Kg
speed of the fish after eating small fish =?
a) using conservation of momentum
m₁v₁ + m₂v₂ = (m₁+m₂) V
15 x 1.10 + 4.50 x 0 = (15 + 4.5)V
16.5 = 19.5 V
V = 0.846 m/s
b) Kinetic energy before collision
KE₁ = 9.075 J
Kinetic energy after collision
KE₂ = 6.98 J
Change in KE = 6.98 - 9.075 = -2.096 J
hence,
mechanical energy was dissipated during this meal = -2.096 J

Answer:
MRCORRECT has answered the question
Explanation:
Since velocity is a vector, it can change either in magnitude or in direction. Acceleration is therefore a change in either speed ordirection, or both. Keep in mind that althoughacceleration is in the direction of the changein velocity, it is not always in the direction ofmotion.
