6. Which Thanksgiving dish contains the most dietary fiber ? (Corn) (Mashed Potatoes) (Sweet Potatoes) (Pecan Pie)
pashok25 [27]

Answer:

The correct option is;

Sweet Potatoes  

Explanation:

The dietary fiber in Corn = 2.7 g per 100 g

The dietary fiber in Mashed Potatoes = 1.3 g per 100 g

The dietary fiber in Sweet Potatoes = 3 g per 100 g

The dietary fiber in Pecan Pie = 2.1 g per 100 g

Therefore, the Thanksgiving dish that contains the most dietary fiber per 100 g is Sweet Potatoes

A 0.40-kg particle moves under the influence of a single conservative force. At point A, where the particle has a speed of 10 m/
yan [13]

Answer:

The value of the potential energy of the particle at point B is 85 joules.

Explanation:

According to the Principle of Energy Conservation, the energy cannot be created nor destroyed, only transformed. The particle at point A has kinetic and potential energy and receives a work due to an external conservative force (Work-Energy Theorem), whose sum is equal to potential energy at point B. Mathematically speaking, the expression that describes the phenomenon is:

K_{A} + U_{A} + W_{A \rightarrow B} = U_{B}

Where:

K_{A} - Kinetic energy at point A, measured in joules.

U_{A} - Potential energy at point A, measured in joules.

W_{A \rightarrow B} - Work due to conservative force from A to B, measured in joules.

U_{B} - Potential energy at point B, measured in joules.

The initial kinetic energy of the particle is:

K_{A} = \frac{1}{2}\cdot m \cdot v^{2}

Where:

m - Mass, measured in kilograms.

v - Velocity, measured in meters per second.

If m = 0.4\,kg and v = 10\,\frac{m}{s}, then:

K_{A} = \frac{1}{2}\cdot (0.4\,kg)\cdot \left(10\,\frac{m}{s} \right)^{2}

K_{A} = 20\,J

Finally, the value of the potential energy at point B is:

U_{B} = 20\,J + 40\,J + 25\,J

U_{B} = 85\,J

The value of the potential energy of the particle at point B is 85 joules.
