Answer:

I think the best answer would be the first but am I the only one wondering why the mom didn't just turn off the phone but instead she had to be extra and wrap them up like a gift to give them after dinner.

Answer:

1 (pitcher), 2 (catcher), 3 (first baseman), 4 (second baseman), 5 (third baseman), 6 (shortstop), 7 (left fielder) 8 (center fielder), and 9 (right fielder)

Explanation:

There are nine fielding positions in baseball. Each position conventionally has an associated number, for use in scorekeeping by the official score

Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance.

Answer:

Plane mirror.

Explanation:

A plain mirror is a mirror with a flat reflecting surface and is made of ordinary glass.

Reflection can be defined as a phenomenon which typically involves a change in the direction of a ray of light or waves as it falls on a smooth surface.

Simply stated, reflection occurs when a ray of light or wavefronts bounces off a smooth surface such as a plane mirror.

Generally, the angle of reflection equals the angle of incidence when a light ray strikes or hits a plane mirror.

The properties or characteristics of the images formed by a plane mirror include;

I. They are virtual and erect (upright).

II. It is the same size as the object formed.

III. It has the same distance from the plane mirror as the distance of the object from the mirror.

Answer:

No

Explanation:

Electromagnetic radiation is used for communications and transmission of information. The waves that are used in this way are radio waves, microwaves, infrared radiation and light.

Answer:

The answer is D

The second law of thermodynamics

Answer:Thus, if each of the charges were reduced by one-half, the repulsion would be reduced to one-quarter of its former value. Also In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. ... And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects.

Hope this helps have a awesome night/day❤️✨

Explanation:

Nothing, until those two objects physically touch each other; contact aligns polarity among the now single shared mass.

(Your question never states if both objects are unique or similar polar charges, so I just assumed they were both neutral objects existing within an electric field.)

So a better question would then be, what is gravity’s relationship with an electric field?

You could solve this with the following: confine the electric field’s volume to a set variable (never increasing nor decreasing in size or shape); density is variable and easily definable. This creates the limit to build upon. This density has to be fluid and has electron mass (full of electrons at rest mass, so with substance but no movement). Within, create a closed system (the hard part in this equation; outside interference like ambient light will eschew results) where each variable of kinetic energy then is accounted for or measurable (including heat and light, and the physical movement of the two objects)

Determine the mass for both objects, calculate gravity for both and each body’s inertia on the other as a sum over distance. record results. Polarity is shared across the masses until there is no longer inertia (one mass or contact).

Answer:

Angular acceleration [tex]= 0.167[/tex] rad/s^2

Explanation:

Given

Initial Angular velocity (w1) [tex]= 5[/tex] rad/s

Final Angular velocity (w2) [tex]= 0[/tex] rad/s

Time taken to change velocity from w1 to w2 [tex]= 30[/tex] seconds

Angular acceleration is equal to the change in angular velocity to the time taken for making thing change

Hence, Angular acceleration

[tex]\frac{w_2 -w_1}{t} \\\frac{5-0}{30}\\0.167[/tex]rad/s^2

Answer:

There are two fundamental types of generators known as AC (alternating current) and DC (direct current) generators. While the technique of producing electricity is the same in both types, AC and DC power become different in terms of their applications – the way in which loads receive electric power.

Explanation:

An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. ... Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.

Answer:

1200 watts at a standard 120v draws 10 amps

Answer:

Trabajo realizado = 600 Nm

Explanation:

Dados los siguientes datos;

Fuerza = 200 Newton

Distancia = 3 metros

Para encontrar el trabajo realizado; Trabajo realizado = fuerza * distancia

Sustituyendo en la ecuación, tenemos; Trabajo realizado = 200 * 3

Trabajo realizado = 600 Nm

Answer:

187.5 m/s (i think)

Explanation:

If you use the formula V= T times displacement you can find this out by doing the following-

Displacement equals 75 m

T equals 2.5 hrs

75x2.5= 187.5

and since velocity is measured in m/s, it becomes

187.5 m/s
