Answer:

Explanation:

Inertia is the property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity.

The more mass, the more inertia. If you increase the mass of the object then you increase the inertia.

Explanation:

heat is thermal energy transferred from a hotter system while temperature is a measure of the average kinetic energy of atoms or molecules in the system

Answer:

Explanation:

Although we do have an equation for this in terms of one-dimensional motion, it's easy enough just to use the mathematical definition of acceleration:

[tex]a=\frac{v_f-v_0}{t}[/tex]  which says, in words, the acceleration of an object is equal to the objects final velocity minus its initial velocity, divided by the change in time. Since everything is given in m and s, our answer will be in m/s/s:

[tex]a=\frac{16.0-4.0}{4.0}[/tex] and

[tex]a=\frac{12.0}{4.0}[/tex] so

a = 3.0 m/s/s

Answer:

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

1. Ultraviolet light (UV)

2. X-rays

3. Gamma-rays

Explanation:

Though there are different types of energy or electromagnetic waves with varying wavelengths, including the likes of Gamma X-rays, ultraviolet light, visible light, infrared radiation, and microwave radiation.

What is more certain is that the atmosphere blocked the high-energy waves from getting to the earth surface or biosphere such as Ultraviolet light (UV), X-rays and Gamma-rays

Answer:

they can have both ways because it turns out that they can go into different ways light waves are associated with constantly like her to certain ways or

most people use the term light waves when they usually mean visible light in physics however these terms like veins are trying to be used as a synonym of electronic waves electric razor made of skull in magnetic and electric field like always they carry energy

Answer:

flux melting

Explanation:

Flux melting is the process that causes magma to form. Flux melting happens when water or carbon dioxide exists added to rock.

When rock is exposed to water or carbon dioxide, flux melting occurs. The rock melts at lower temperatures as a result of these substances. This causes magma to form where it had a solid structure before. Around subduction zones, flux melting also happens, much like heat transfer.

Flux melting happens in igneous petrology and volcanology when water and other volatile substances are added to hot solid rock, depressing the solidus. Flux is a material, such as salt, that produces a mixture with a metal oxide that has a low melting point (liquidus) in engineering and metallurgy.

Answer:

hello your question is incomplete attached below is the complete question

answer : Conduction, Lattice vibration  ( B )

Explanation:

The thermal transfer of energy occurs in a solid like a copper rod following two process therefore the second process and method are

Lattice vibration  and  conduction

Lattice vibration is the movement/oscillation of atoms in a solid and this is caused by the change/increase in temperature applied to the solid and these vibrations will lead to the thermal transfer of energy via conduction since the atoms are bounded together .

Answer:

1840 J

Explanation:

From the question given above, the following data were obtained:

Specific heat capacity (C) = 0.46 J/gºC

Mass (M) = 50 g

Initial temperature (T₁) = 20 °C

Final temperature (T₂) = 100 °C

Heat (Q) required =?

Next, we shall determine the change in the temperature. This can be obtained as follow:

Initial temperature (T₁) = 20 °C

Final temperature (T₂) = 100 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 100 – 20

ΔT = 80 °C

Finally, we shall determine the heat required. This can be obtained as follow:

Specific heat capacity (C) = 0.46 J/gºC

Mass (M) = 50 g

Change in temperature (ΔT) = 80 °C

Heat (Q) required =?

Q = MCΔT

Q = 50 × 0.46 × 80

Q = 1840 J

Thus, 1840 J of heat energy is required.

Answer:

0.4m/s

Explanation:

[tex]F = ma[/tex] where F= force, m= mass, and a=acceleration

we also know that,

a = Δv / t where Δv = change in velocity and t = time

thus F = m ( Δv / t)

[tex]2000=50(\frac{v}{0.01})[/tex]

[tex]\frac{2000}{5000} = v[/tex]

0.4m/s = Δv

Answer:

* the two plates of the same sign  E = 0

* the two plates of different sign    E/e = 2

Explanation:

In this exercise, the relationship between the field created by a plate and two infinite plates is asked.

The electric field created by each plate has the value of "e", which is related to the charge on the electric plate.

                 e = [tex]\frac{ \sigma }{2 \epsilon_o}[/tex]

If the plate is negative the electric field is directed towards the plate and if the plate is positive the electric field is directed out of the plate.

The test charge is always positive.

When we have two plates, we have several possibilities

* the two plates of the same sign

therefore the resulting electric field on the test charge is

              E_total = e - e

              E = 0

* the two plates of different sign

              E_total = e + e

               E = 2 e

the relationship between the two fields is

             E/e = 2
