Explanation:

The amplitude of the electric field of the light wave is typically measured in volts per meter (V/m).  It is a measure of the intensity of the light wave.

The amplitude of the electric field of a light wave is the maximum value of the electric field strength at any point in space during one cycle of the wave. It is a measure of the intensity of the light wave. The unit for measuring the electric field strength is volts per meter (V/m).

This means that for each meter of distance, the electric field strength changes by a certain number of volts. The amplitude of the electric field of a light wave can vary depending on the frequency and energy of the photons that make up the wave. In general, higher frequency light waves have a higher amplitude and are more intense than lower frequency light waves. The amplitude of the electric field is a key factor in determining the properties and behavior of light waves.

If a baseball has a negative velocity and a negative acceleration, its speed is decreasing.

Velocity is a vector quantity that includes both magnitude (speed) and direction. In this case, the negative velocity indicates that the baseball is moving in the opposite direction of a chosen positive reference direction. Acceleration, on the other hand, represents the rate of change of velocity and also includes both magnitude and direction.

When the velocity and acceleration have the same sign (both negative in this case), it means that the baseball is slowing down. This is because the acceleration is acting in the opposite direction to the velocity, which results in a decrease in speed. Therefore, the speed of the baseball is decreasing.

Answer:

Force = Mass * Acceleration

the maximum torque exerted by the 54-kg person on the bike pedals when climbing a hill is 84.672 Nm.

To find the maximum torque exerted by the person, we need to use the formula:

Torque = Force x Distance

First, let's find the force exerted by the person. Since the person puts all her weight on each pedal, the force exerted by one pedal is equal to her weight. Using the formula:

Force = mass x gravity

where mass = 54 kg and gravity = 9.8 m/s^2 (acceleration due to gravity), we get:

Force = 54 kg x 9.8 m/s^2 = 529.2 N

Next, let's find the distance from the center of the pedal rotation (i.e. the radius of the circle) to the point where the force is applied (i.e. the point where the person's foot is pressing on the pedal). This distance is given as 16 cm, but we need to convert it to meters to use it in the torque formula. So:

Distance = 16 cm = 0.16 m

Now we can calculate the maximum torque:

Torque = Force x Distance
Torque = 529.2 N x 0.16 m
Torque = 84.672 Nm

Therefore, the maximum torque exerted by the person is 84.672 Nm.

Answer:

v = 4.79 10³ m / s

Explanation:

For this exercise we will use the universal law of gravitation and Newton's second law

          F = G M m / r²

where G is the gravitational constant, m the mass of the satellite, M the mass of the Earth, r the distance from the center of the planet to the satellite

           F = m a

since the satellite has a circular path, the acceleration is centripetal

          a = v² / r

we substitute

          G M m / r² = m v² / r

           G M / r = v²

We calculate

          v² = 6.67 10⁻¹¹ 5.98 10²⁴ / 6.96 10⁶

Answer:

When the student slides the rock along the flat surface of the frozen pond, according to Newton's second law of motion, the rock is given an initial velocity of motion. According to Newton's first law of motion, the rock will continue to slide indefinitely unless it is slowed or stopped by an opposite force. According to Newton's third law, the rock experiences a reaction force from the force of friction of the ice which slows it down at a rate given by Newton's second law of motion and the rock is seen to decelerate

Explanation:

Newton's first law of motion, states that an object will remain at rest or maintain a uniform motion in a straight line, unless impressed upon by an external force

Newton's second law states that an applied force is equal to the rate of change of momentum it produces

Newton's third law states action and reaction are equal and opposite.

Fnet <F1+ F₂ because the net force will include the component of frictional force. Option C.

Forces are balanced when people on both sides of the rope are pulling the same amount in opposite directions. As a result, there is no motion. Balanced forces can cancel each other out. If the forces are balanced, the object will not move. When two forces act in the same direction, they add. Equal forces acting in opposite directions are called equilibrium forces.

Equilibrium forces acting on an object do not change the object's motion. Adding equal forces in opposite directions results in a net force of zero. Balanced forces acting on the same object, but in opposite directions. The net force due to these forces is zero. The sum of the magnitudes of the forces is also equal to the sum of the two forces acting in the same direction.

a. Controllable variance of Derr Company if actual total overhead is $980 and budgeted (flexible) overhead at units produced 800 is $180.

b Volume variance is $0.

c. Total overhead variance is $180.

To determine the controllable variance, we can use the formula:

Controllable variance = Actual cost – Budgeted cost (At Actual Units Produced)

= $980 – $800

= $180

Answer:

Se obtienen 2,27 gramos de metanol.

Explanation:

La reacción entre monóxido de carbono e hidrógeno para producir metanol es la siguiente:

CO + 2H₂ → CH₃OH  

Para encontrar el reactivo limitante y el reactivo en exceso, debemos calcular el número de moles de CO y H₂:

\(\eta_{CO} = \frac{m}{M} \)              

En donde:    

m: es la masa

M: es el peso molecular  

\(\eta_{CO} = \frac{m}{M_{CO}} = \frac{2,0 g}{28,01 g/mol} = 0,071 moles \)

\(\eta_{H_{2}} = \frac{2,0 g}{2,02 g/mol} = 0,99 moles \)

Dado que la relación estequiométrica entre CO y H₂ es 1:2, el número de moles de hidrógeno gaseoso que reaccionan con el monóxido de carbono es:

\( \eta_{H_{2}} = \frac{2}{1}*0,071 = 0,142 moles \)      

Entonces, se necesitan 0,142 moles de H₂ para reaccionar con 0,071 moles de CO y debido a que se tienen más moles de H₂ (0,99 moles) entonces el reactivo limitante es CO y el reactivo en exceso es H₂.

Ahora podemos encontar la masa de metanol obtenida usando el reactivo limitante (CO) y sabiendo que la realcion estequiométrica entre CO y CH₃OH es 1:1.    

\( \eta_{CH_{3}OH} = \eta_{CO} = 0,071 moles \)

\( m = 0,071 moles*32,04 g/mol = 2,27 g \)

Por lo tanto, se obtienen 2,27 gramos de metanol.

Allowable Stress Design (ASD) and Load and Resistance Factor Design (LRFD) are two approaches used in structural engineering for designing structures. They have similarities in considering strength requirements, load types, material properties, structural elements, and structural safety. However, they differ in their design philosophies, basis for design, treatment of loads and resistances, load and resistance factors, design equations, and flexibility in design decisions.

Similarities:

Strength requirements: Both ASD and LRFD aim to ensure that structural elements have adequate strength to resist the applied loads.

Load types: Both methods consider various load types, such as dead loads, live loads, wind loads, seismic loads, etc., in their design calculations.

Material properties: Both ASD and LRFD account for material properties, such as yield strength, ultimate strength, modulus of elasticity, etc., in their design equations.

Structural elements: Both methods address different structural elements, such as beams, columns, connections, foundations, etc., and provide design guidelines specific to each element.

Structural safety: Both ASD and LRFD prioritize structural safety and aim to prevent failure or collapse under the anticipated loads.

Differences:

Basis for design: ASD is based on allowable stress limits, where the stress in a structural member should not exceed the allowable stress, while LRFD is based on the resistance of the member to loads and the reliability of that resistance.

Treatment of loads and resistances: ASD uses service loads directly and applies appropriate factors of safety to determine the allowable stress. LRFD treats loads as probabilistic and incorporates load factors to account for uncertainties in the applied loads, while resistance factors are used to account for uncertainties in material strength and other resistances.

Load and resistance factors: ASD primarily relies on factors of safety applied to the loads, while LRFD uses load and resistance factors to modify the nominal loads and resistances, respectively.

Design equations: ASD employs design equations based on allowable stresses and factors of safety, whereas LRFD uses equations that compare the loads and resistances with appropriate load and resistance factors.

Flexibility in design decisions: ASD allows for more flexibility in design decisions as engineers can make adjustments based on judgment and experience, while LRFD provides a more consistent and systematic approach with prescribed load and resistance factors.

In summary, ASD and LRFD share similarities in considering strength requirements, load types, material properties, structural elements, and structural safety. However, they differ in their design philosophies, basis for design, treatment of loads and resistances, load and resistance factors, design equations, and flexibility in design decisions.

A subtype discriminator is the attribute in the supertype entity that determines to which entity subtype each supertype occurrence is related. Option (a) is correct.

The entity supertype is a concept in a database schema that represents a group of entities that share the same attributes or characteristics. A subtype is a subset of entities that possess specific distinguishing characteristics or attributes that are not present in the supertype. A subtype will have at least one different attribute or relationship, apart from all of the characteristics that the supertype contains.

A subtype is a refinement of a supertype entity. An entity type, known as the supertype, has multiple subtypes that can be derived from it. Subtypes may be exclusive (disjoint) or nonexclusive (overlapping). Exclusive subtypes contain nonoverlapping entities, whereas nonexclusive subtypes have overlapping entities.

Supertype and subtype entities can be used in conjunction with the entity-relationship model. A subtype is a distinct entity that has one or more attributes that are specific to it but not present in its supertype. The subtype of an entity is said to be derived from its supertype by extension or specialization.
