What occurs when an object travels in a curved path
babymother [125]
<span>When an object travels in a curved path, there must be a force acting toward the center of the circular trajectory. This force is called "centripetal force", and it cause an acceleration of the object, called "centripetal acceleration". The effect of this acceleration is that the velocity of the object changes in direction: however if the circular motion is uniform, the speed (=the magnitude of the velocity) does not change. In this case, the magnitude of the centripetal force is given by
</span>F=m \frac{v^2}{r}<span>
where m is the mass of the object, v its velocity, and r the radius of the circular path.</span>

5.00 kg of liquid water is heated to 100.0 °C in a closed system. At this temperature, the density of liquid water is 958 kg/m3.
user100 [1]

Answer:

1.04\times 10^7\ J.

Explanation:

In the question given :

Pressure is constant

Therefore, Work done, W=P\times\Delta V

Pressure, P=1.01 × 105 Pa.

Final volume, V_f=8.50\ m^3.

Initial volume, V_i=\dfrac{Mass}{density}=\dfrac{5}{958}=5.22\times10^-3\ m^3.

Therefore, W=8.58\times 10^{5}\ J.

Also, Heat Given, Q=m\times L=5\times 2.26\times 10^{6}\ J=1.13\times 10^7\ J.

Also, according to First law of thermodynamics:

\Delta U=Q-W=(1.13\times 10^7)-(8.58\times 10^5)=1.04\times 10^7\ J.

Hence, this is the required solution.
