Find the amount of labor necessary to move an object along the specified orientated curve given the force field F. y = 3x2 on the parabola from (0, 0) to F = (y, x) (4, 48).

<h3>How can you determine the work a force field performs along a curve?</h3>

A variable force's infinitesimal work can be defined in terms of the force's components and the displacement along the path,

<h3>How do you assess the force field F's work?</h3>

(c) Next, determine the work that the force field F performed on the object to move it through the field by moving it along the vector d. W = F d is the formula for work.

1. Which statement about friction is true?(1 point) A. Static friction and kinetic friction in a system always act in the same d
ArbitrLikvidat [17]

Answer:

true 1Ay 2D

Explanation:

1) In this exercise you are asked to investigate which statements are true

A) True. The friction force opposes the movement caused by the external force,

B) False. Mantuano in the opposite direction force

C) False. The static and scientific friction force act in the same direction, since the second appears when the movement does not start and the static friction decreases.

D) Fale the static and kinetic friction forces act in the same direction

2) How to overcome friction on a ramp

A) False. If the texture of the surface becomes rough, the friction force increases

B) False. Pressing the brick against the surface increases the normal and as the friction is proportional to the normal, it also increases

C) False. By lowering the table the weight component in the friction direction decreases

D) True. When lifting the board, the weight component increases and therefore can become greater than the friction

A temperature of a 0.349 kg sample of copper decreases from 87.0 °C to 21.0 °C. How much heat
Arte-miy333 [17]

We have that heat flow out of the copper sample  is mathematically given as

Q=8.86809J

<h3> Heat flow</h3>

Question Parameters

  • A temperature of a 0.349 kg sample of copper
  • decreases from 87.0 °C to 21.0 °C.

Endothermic Reaction

It is common knowledge that an endothermic reaction is one where the system absorbs heat energy from the <em>environs</em>.

Exothermic Reaction

An exothermic reaction is one where the system releases heat energy to the <em>environs</em>.

Generally the equation for Heat   is mathematically given as

Q=mCdt\\\\Therefore\\\\Q=0.349*0.385*(87-21)

Q=8.86809J

While investigating the relationship between voltage, current, and resistance, students connected different batteries to differe
GuDViN [60]

Produced the model is the resistance of the circuits decreased as a battery voltage increased (option-B).

<h3>What connection does there exist between voltage and current, current and resistance, and voltage and resistance?</h3>

Ohm's Law describes how current, voltage, and resistance are related to one another. According to this, as long as the temperature doesn't change, the current flowing through a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.

The more work a certain quantity of electrons can accomplish at a given voltage. The quantity of electrons that are presently moving through any one point in a circuit at any particular time is known as the current. At the same voltage, a larger current can perform more work. Current times voltage equals power.
