Answer:

you can write some points its an explanation

and similarities. or common

Explanation:

Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process (see the 1ˢᵗ law of thermodynamics).

The faster the atoms or molecules move, the more heat or thermal energy they have. ... A hair straightener turns the electrical energy from a wall outlet into heat (thermal energy). 4. As electricity runs through the filaments in a space heater, the electrical energy is converted into heat (thermal energy).

What is the mural with an area of 18 m squared

White raven [17]

So the mural has an area of 18m squared
=> A = 18m^2
in getting the area of a square we use to formula = s^2, but since the area is already given, we need to find the value of each sides of the square. Thus, we simply need to do it backward.
we need to find the square root of the area
=> square root of 18m^2
=> 4.24m
Therefore that mural has a sides of approximately 4.24 meters

Consider two planets in space that gravitationally attract each other if the mass of one of them stays the same and the mass of

irga5000 [103]

Answer:

D. half as much

Explanation:

let m and M be the mass of the planets and r be the distance between them.

then: the force of attraction between them is given by,

F = G×m×M/(r^2)

if we keep one mass constant and double the other and also double the distance between them.

the force of attraction becomes:

F1 = 2G×m×M/[(2×r)^2]

= 2G×m×M/[4×(r)^2]

= (1/2)G×m×M/(r^2)

= 1/2×F

therefore, when you double one mass and keep the other mass constant and double the distance between the masses you decrease the force by a factor of 1/2.

A man attaches a divider to an outdoor faucet so that water flows through a single pipe of radius 9.25 mm into four pipes, each

irinina [24]

Answer:

1.24 m/s

Explanation:

Metric unit conversion:

9.25 mm = 0.00925 m

5 mm = 0.005 m

The volume rate that flow through the single pipe is

$\dot{V} = vA = 1.45 * \pi * 0.00925^2 = 0.00039 m^3/s$

This volume rate should be constant and divided into the 4 narrower pipes, each of them would have a volume rate of

$\dot{V_n} = \dot{V} / 4 = 0.00039 / 4 = 9.74\times10^{-5} m^3/s$

So the flow speed of each of the narrower pipe is:

$v_n = \frac{\dot{V_n}}{A_n} = \frac{\dot{V_n}}{\pi r_n^2}$

$v_n = \frac{9.74\times10^{-5}}{\pi 0.005^2} = 1.24 m/s$

Why do experts describe the rate of fossil fuel use as unsustainable

svetlana [45]

Explanation:

Experts describes the rate of fossil fuel use as unsustainable because fossil fuel is a non-renewable source of energy. Fossil fuels are usually formed by a series of biology, chemical and geological activities acting in nature. They take several millions of years to form and accumulate in nature.

Most of the internal combustion engines in automobiles, factories e.t.c relies on fossil fuels.
With the heavy demand, reserves are be depleted.
The rate of formation of new sources is very slow and may not suffice in our life time.
Therefore, we cannot continue to use this source of energy that cannot be adequately sustained.
