Explanation:

Answer:

A

Explanation:

Carbon-14 testing of organic material such as wood can approximate the age by measuring the radioactive decay rate of the carbon-14 in the wood. From that a baseline for the trees age can be established and the ring patterns can by applied to a time period.

Answer:

Gravity. An object is moving across a surface, but it does not gain or lose speed.

Explanation:

The basic idea. Physicists see gravity as one of the four fundamental forces that govern the universe, alongside electromagnetism and the strong and weak nuclear forces.

If you pull horizontally on a 50 kg crate with a force of 400 N and the friction force on the crate of 150 N, then the acceleration of the crate would be 5 m / s² .

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

As given in the problem if you pull horizontally on a 50 kg crate with a force of 400 N and the friction force on the crate in 150 N.

The net force acting on the crate = 400 N - 150 N

                                                        = 250 N

The acceleration of the crate = 250 / 50

                                                 = 5 m / s²

Thus, the acceleration of the crate would be 5 m / s² .

Answer:

D) Strong gravitational force of the earth

Explanation:

Gravitational force is the force that attracts to objects with mass.This forces tries to pull masses together, that is why attractive in nature.

As the shape of a molecule has a lot to do with the polarity of the compound, the molecular structure influences the molecular properties. Polar compounds tend to dissolve in polar compounds, forming solids or liquids with higher boiling and melting points.

A physical property is a property of matter that is unrelated to changes in its chemical composition. Density, color, hardness, melting and boiling points, and electrical conductivity are all examples of physical properties.

In the solid state, the structure determines how individual polymer molecules can orient. As a result, physical properties such as density, crystallinity, melting point, and strength are affected.

Intermolecular forces - forces that attract one molecule to its neighbors - van der Waals attractions or hydrogen bonds - govern physical properties.

Because the intermolecular forces of attraction are relatively weak, molecular substances tend to be gases, liquids, or low melting point solids.

Thus, this way the molecular structure of a material influence its physical properties.

Answer: 14

Explanation:

Force(normal)*coefficient

The static friction force is a force that prevents motion of an object kept on a surface, due to the interaction of the surface of the object and the surface on which it is kept

Reason:

The known parameter are;

The weight of the block, W = 35 N

The static friction of the surface of the table surface, [tex]\mu_s[/tex] = 0.40

Required:

To find the minimum force to start the block moving

Solution:

The force required to start the block moving is given by the frictional force that needs to be surpassed

Force required, F = Force of friction

Force of friction = Normal reaction × Coefficient of static friction

On a flat surface, the normal reaction = The weight of the object

∴ Force of friction, [tex]F_f[/tex] = Weight of the object × Coefficient of static friction

Which gives;

[tex]F_f = W \times \mu_s[/tex]

[tex]F_f = 35 \, N \times 0.40 = 14 \, N[/tex]

Force required, F = Force of friction, [tex]F_f[/tex] = 14 N

The minimum force required to start the block moving, F = 14 N

Explanation:

3. The word circuit means "go around", therefore a circuit is a pathway or closed path around which electricity (or water) flows.

4. Electrons flowing through a wire can be compared to water flowing through a hose. Once the flow of electrons or water is going, work, is performed.

5. You would get shocked in a bumper car by touching the floor and the ceiling at the same time. This means you are completing the circuit allowing electricity to flow.

6. Electricity from a wall outlet has enough energy to stop your heart.

7. Electricity is the flow of electrons, because electrons move or jump from atom to atom.

8. Materials that allow electrons to move easily from atom to atom are called conductors.

9. Materials that do not allow electrons to flow easily are called insulators.

10. Semi- conductors are materials that are somewhere in between .

11. Voltage is the force or pressure of electricity and is compared to the amount of water pressure in a hose.

12. Current (amps ) is the amount of electricity and is compared to the amount of water in a hose .

Answer:

s₁ = 240,000 km

Explanation:

The distance between both the focuses f₁ and f₂ will be the sum of distances of the moon from each focus at a given point. Therefore,

s = s₁ + s₂

where,

s = total distance between the focuses = ?

s₁ = distance between f1 and moon = 200,000 km

s₂ = distance between f₂ and moon = 300,000 km

Therefore,

s = 200,000 km + 300,000 km

s = 500,000 km

Now, when the distance from f₂ becomes 260,000 km, then the distance from f₁(planet) will become:

s = s₁ + s₂

500,000 km = s₁ + 260,000 km

s₁ = 500,000 km - 260,000 km

s₁ = 240,000 km
