Analyze that, “Convection is equal to the Conduction plus fluid flow.”

Physics

Answer:

Convection is equal to the conduction plus fluid flow.

Explanation:

Convection is a mode of heat transfer that requires the movement of the molecules of the medium from one point to another. It takes place majorly in fluids (liquids and gases). While conduction is a process by which heat is transfered by the vibtation of molecules of a medium at their possitions, thereby colliding with other neighbouring molecules to transmit heat.

Before convection could occur, there must be conduction of heat by the molecules of the medium which causes their motion. According to the kinetic molecular theory, any molecule of the medium close to the source of heat conducts heat, becomes less dense and thus moves so that its initial position would be occupied by another denser molecule. This continous process generate convection or convectional current. Therefore, convection is as a result of conduction and fluid flow because a molecule must first conduct heat before it moves.

I need to know everything about mars. I need to do a full 3 page essay. please help!
zheka24 [161]

Answer:

Mars was the Roman god of War along with an agricultural guardian. He is most closely related to the god Ares of Greek Mythology. In Roman mythology, he was second in importance to Jupiter, Rome's god of the Skies and Weather. Jupiter was the king of the Roman Pantheon, husband of the queen of gods Juno. He was also Mars' father. Unlike his Greek Counterpart, Ares who was most known for his hot headed temper and associated with hate and anger, Mars was part of the Romans <em>Archaic Triad</em>, sort of like the Big Three of Greek religion. The members of said Triad included Mars, Jupiter, and Quirinus, who had no Greek equivalent. Mars was most commonly depicted in posed of valor and strength, carrying swords or shields. He wore common Roman armor, including the plumed helmet. He was pictured as a strong leader of the Roman Army. The fourth planet from the Sun was given the name Mars when it was first discovered because it was red, much like the main color the Roman god was affiliated with.

A force of 30 N is applied tangentially to the rim of a solid disk of radius 0.10 m. The disk rotates about an axis through its
den301095 [7]

Answer:

m = 4.0 Kg

Explanation:

  • Using an analogy with the Newton's 2nd law for point masses, for rigid bodies, the external net torque on a rigid body, is equal to its rotational inertia (I), times the angular acceleration (α) of the body, as follows:

       \tau_{ext} = I* \alpha (1)

  • Since the magnitude of the torque is the product of the value of the force times the perpendicular distance between the line of action of  the force and the axis of rotation, and the force is tangential to the rim of the disk, we can write the following expression:

       \tau = F*r*sin 90 = F*r (2)    

  • For a solid disk, the rotational inertia regarding an axis through its center, and perpendicular to its face is as follows:

      I = \frac{m*r^{2}}{2}  (3)

  • Replacing (3) in (1), and (2) in the left side of (1) also, we can solve for m, as follows:

       m = \frac{2*30.0N}{0.1m*150(1/s2)} = 4.0 Kg (4)

  • So, the mass of the disk is 4.0 Kg.

zubka84 [21]

A statement which describes the changes that occur in this sequence of events is: 2. matter is converted into energy and then energy is converted into matter.

<h3>What is the law of conservation of matter?</h3>

The law of conservation of matter (LOCOM) states that mass can neither be created nor destroyed in any chemical reaction.

Similarly, the energy possessed by a matter can neither be created nor destroyed, but it can only be converted from one energy form to another.

In this context, we can logically deduce that a statement which best describes the changes that occur in this sequence of events is that matter is converted into energy and subsequently, energy is converted into matter.

a block of wood is found to have dimensions of 6.21 cm x 4.63 cm x 5.34 cm. Calculate the volume of the block
34kurt

Answer:

153.54 cm³

Explanation:

The formula for the volume of a cube is v = lwh, where l is the length, w is the width, and h is the height of the block.  Multiply, 6.21*4.63*5.34 = 153.54
