Answer:
V₂ = 46.99 μL.
Explanation:
Given that
V₁ = 45.1 μL
T₁ = 24.7°C = 273 + 24.7 = 297.7 K
T₂ = 37.2°C = 273+37.2=310.2 K
Lets take ,The final volume = V₂
We know that ,the ideal gas equation
If the pressure of the gas is constant ,then we can say that


Now by putting the values in the above equation we get

V₂ = 46.99 μL.
The final volume will be 46.99 μL.
Exothermic is the term for a reaction where energy is released.
Answer:
The work done by the worker on the crate is 4830 J.
Explanation:
Given that,
Force = 1080 N
Horizontal force = 345 N
Distance d = 14 m
Coefficient of friction = 0.22
We need to calculate the work done
Using formula of work done

F = force
d = distance
Put the value into the formula


Hence, The work done by the worker on the crate is 4830 J.
To accelerate a 34.01 kg-car at 0.55 m/s², a force of 19 N will be required, according to Newton's Second Law of Motion.
<h3>What does Newton's Second Law of Motion state?</h3>
Newton's Second Law of Motion states that acceleration (a) happens when a force (F) acts on a mass (m).
We want a car of mass 34.01 kg to have an acceleration of 0.55 m/s². We can calculate the required force using Newton's Second Law of Motion.
F = m × a = 34.01 kg × 0.55 m/s² = 19 N
To accelerate a 34.01 kg-car at 0.55 m/s², a force of 19 N will be required, according to Newton's Second Law of Motion.
