Answer:

 F = 9.338 10⁻⁴ N

Explanation:

For this exercise let's use the law of universal gravitation

          F = [tex]G \frac{m_1m_2}{r^2}[/tex]

let's reduce the magnitudes to the SI system

          r = 5 cm (1 m / 100cm) = 0.05 m

let's calculate

            F = 6.67 10⁻¹¹ 50 700 / 0.05²

            F = 9.338 10⁻⁴ N

the direction of the force is in the direction between the particles

Answer:

His average speed is 980 units

Answer:

pressure = force/area

force = 200N

area = πr², π =3.142, r = 12 cm = 0.12 m

pressure = 200/3.142×(0.12)²

p = 200/3.142×0.24

p = 200/0.754

p = 265.25 Nm-¹ or 265.25 Pa

Answer:

With the increase in depth, age of layer increases.

Explanation:

According to the law of superposition, the layer of the Earth that is present in the deep is considered as the oldest layer while on the other hand, those layer which is present on the top of all layers is considered as youngest layer of earth. When we move from the top layer towards the bottom layer, the age of layer increases or in other words, when we move upward the age of the layer decreases so label the layers of earth on the basis of this phenomenon.

Answer:

  τ = 0

Explanation:

The moment of a force is defined by

          τ = F x r

where bold indicates vectors.

We can write this equation in module form

           τ = F r sin θ

the amount without ea r is called the breaststroke and is the distance perpendicular to the pivot point.

The line of action of the force passes through the turning point whereby

r = 0,

Consequently the moment is also zero

            τ = 0

Answer:

Voltage = 10.54545

Given -

Current (I) - 11

Amps - 11

Resistance - 0.95868

Power - 116

We can conclude:

The voltage will be 10.54545, because of Ohm's Law:

Ohm's law states that:

Voltage (V) = Current (I) * Resistance (R)

Power (P) = Voltage (V) * Current (I)

Explanation:

in position 2 and three it would have less energy cause there is less force being exerted to give it that push, but at the end position and the first position there is going to be more force and energy behind the ball.

Answer:

None of the animals are from the same species

Explanation:

The exact question is as follows :

Given -

Felis catus

Sylvilagus audubonii

Parus inornatus

Euarctos americanus

Check out the list of scientific names. These names all represent animals. These are all animals but they cannot reproduce to produce fertile offspring with each other.

To find - What conclusion can be drawn from the past statement?

Solution -

The conclusion we can made from past statement is that - None of the animals are from the same species

Reason -

When two members of the same species reproduce, they produce fertile offspring.

According to the scientific names of the animals, there are different genus and species names.

A thick layer of material with a low thermal conductivity reduces the rate of heat transfer from the ceiling into the roof space.

Answer:

tire marks are due to the increase in thermal energy

Explanation:

When a tire is spinning at a given speed when the brakes are applied hard, the friction between the tire's particulate and the ground surface is high enough that some tire particles are transferred to the ground.

This is reflected in the heat transfer from the tire to the ground.

Consequently, tire marks are due to the increase in thermal energy and the change in the friction force of the tire.

Answer:

Going super fast and stopping abruptly causes friction which causes heat thus it melts the surface of the tire.

Explanation:

This is example answer for edmentum :)

heating of anything increases the kinetic energy of its molecules, so the molecules will move faster.

A helium balloon's temperature is raised by 1°C. This will cause molecules to move faster.

The temperature has an impact on this average kinetic (motional) energy. Their average kinetic energy likewise rises when gas molecules warm up.

As a result, they travel more quickly and collide more frequently and violently inside the balloon. The temperature has an impact on the hot air balloon's internal pressure. The molecules move more quickly and forcefully against the interior wall of the balloon as they warm up.

A region of the balloon is subjected to more force due to the gas particles' greater velocity, which raises the pressure there.

Therefore, the temperature of a helium balloon is increased by 1°C. Molecules will move more quickly as a result.

Answer:

Climate change, where there is an increase in the average temperature, due to continuous human activities. These activities increase greenhouse gases in the atmosphere.

Explanation:

Alaska is the largest state in the United States, and it has a cold climate. The climate changed over time as human activities such as coal mining contributed to greenhouse gas emissions leading to global warming. Over the years. the variations in weather leading to climate change melt the permafrost (frozen ground below the soil surface) causing ocean waves to erode the land and destroy property.

Answer:

980 is the expected number of nondefective lightbulbs in a random sampling of 1,000 bulbs

Explanation:

If the company claims is right, this is the task that should be done

Lightbulbs = 1,000 * 0.98 = 980

Therefore, 980 working bulbs is expected out of a sample of 1,000 lightbulbs

Answer:

[tex]\huge\boxed{\sf P.E. = 240\ MJ}[/tex]

[tex]\huge\boxed{\sf K.E. = 19.6\ MJ}[/tex]

Explanation:

Given:

Mass = m = 200,000 kg

Vertical Distance = h = 120 m

Speed = v = 14 m/s

Acceleration due to gravity = g = 10 m/s²

Required:

1) Gravitational Potential Energy = P.E = ?

2) Kinetic Energy = K.E. = ?

Formula:

1) P.E. = mgh

2) K.E. = [tex]\displaystyle \frac{1}{2} mv^2[/tex]

Solution:

1) P.E. = (200,000)(10)(120)

P.E. = 240,000,000 Joules

P.E. = 240 Mega Joules

P.E. = 240 MJ

2) K.E. = 1/2 (200000)(14)^2

K.E. = (100000)(196)

K.E. = 19,600,000 Joules

K.E. = 19.6 MJ

Answer:

Similitudes y diferencias entre los músculos de los peces y los de los animales terrestres.

Explicación:

Los músculos de los peces se diferencian del músculo de los animales terrestres porque los peces tienen músculos rojos, rosados y blancos. También tienen tejido muscular de pescado que se compone de músculo estriado al igual que el músculo de los animales terrestres. La mayor parte del tejido muscular de los peces es de color blanco, pero muchos peces también tienen una cierta cantidad de tejido oscuro de color marrón o rojizo. El músculo oscuro se encuentra justo debajo de la piel a lo largo del costado del cuerpo.

Answer:

13 atoms

Explanation:

Look at the subscripts.

“Mg₃” means that there are 3 magnesium atoms; “PO₄” means that there is 1 phosphorus atom and 4 oxygen atoms. But note that the PO₄ group has a subscript too: 2. This multiplies the atom count by 2, so you have 2 phosphorus atoms and 8 oxygen atoms.

3 + 2 + 8 = 13

(hope this helps can i plz have brainlist :D hehe)

There are total 26 atoms in 2Mg₃(PO₄)₂ compound. in one Mg₃(PO₄)₂, there are 13 atoms. Therefore, in 2 Mg₃(PO₄)₂ units, there are 26 atoms  in total.

A chemical formula is used identify a compound and to indicate chemical composition. The molecular formula of a compound is written based on the chemical symbol of each constituent atoms and their numbers.

The number of the atoms of each elements are represented as subscripts for each elemental symbol. In the given compound Mg₃(PO₄)₂, one unit of the compound contain 3 Mg atoms, and 2 PO₄ units means 2 P and 8 oxygen atoms. Hence there are 13 atoms in one unit.

There are 2 such units of this compound. Therefore, the total number of atoms present in 2 units Mg₃(PO₄)₂ compound is 13×2 =26.
