Answer:
Boiling a kettle is an example of both thermal and kinetic energy. Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Heat energy is another name for thermal energy. Kinetic energy is the energy of a moving object.
it's kinetic!
Empujamos un baúl 3 metros, para ello aplicamos una fuerza de 200 Newton. ¿Cuál es el trabajo realizado?
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

What happens to the force between charged and uncharged objects as the distance between them decreases?
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).

What happens to the arrangement of atoms in matter as it is heated?
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.

Why do some organisms never turn into fossils?
A. They are far too large to be buried in the ground.
B. They are made mostly of soft tissues.
C. They contain too much protein to be preserved.
D. They contain chemicals that prevent the hardening of their bodies.
Answer:
The answer is B.
Explanation:
Since they are made up of soft tissues, they decompose become they become fossils.

A sharpening wheel is traveling at 5 rad/s, it slows down to rest in 30 seconds while sharpening an axe. What is its angular acceleration?
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
Speed = Distance Time Velocity = 1. Find the velocity of a truck that travels 75miles north in 2.5 hours? List: Equation: Substitution: Answer with units:
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

Explain why a charged body loses its charge if we touch it with our hand?
if u answer me I can give u brainliest ☺️
Answer:
Explanation: A charged body loses its charge when we touch it with our hand because some of the charge flows through our body to the ground earthing. As a result the charge on the body decreases every time we touch it. This is because of earthing.
Explanation:
yw .
Explanation:
When we touch a charged body, it loses its charge, due to the process of earthing. Our body is a good conductor of electricity. It transfers the charges to the earth

Name two devices we use generators in. Describe how they work.
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.
