Answer:

Inertia

Explanation:

Inertia is best defined as the ability of an object to resist a change in position or movement. That is why when an object has a higher mass, the higher the inertia. Imagine an oncoming truck that is fully loaded versus you. The tendency for the truck to change its movement would be difficult because of its its mass. It has a lot of inertia.

For this case we have by definition, that the Ampere, is the unit of electric current intensity.

For its part, the electric current is a measure of the velocity at which the electric charge flows.

The symbol of the current is A. We have that 1 Ampere is equivalent to an electric charge of a coulomb per second.

Answer with Explanation:

When solving a problem in math, chemistry or physics, it is necessary to understand all the words and their definitions.  If not, start with finding out their meanings, one by one.

Here the key word to know is pascal, (P), which is a unit of measure for pressure, defined as

pressure = Force / applied area

1 pascal = 1 newton / square metre or

1 P = 1 N/sq.m.

Here, we have been given:

Force = 150 N

Area = 0.25 m^2.

Thus the pressure

= Force / Area

= 150 N / 0.25 m^2

= 150/0.25  N/m^2

= 600 pascals.

How does the thickness of the wire affect the strength of an electromagnet?

Answer:

How does the thickness of the wire affect the strength of an electromagnet

Explanation:

Generally, electromagnet strength increases with an increase in wire thickness. From the theory of electric circuit, the resistance of an electric wire is inversely proportional to the cross sectional area of the electric wire. Mathematically, we have:

R ∝ 1/A

Where:

R is the resistance of the electric wire; A is the cross sectional area of the wire. Therefore, for a large cross sectional area, the resistance will be very low, and the electric current passing through the electromagnet will be high. This will create a very high magnetic field. Thus, the question that Maya will most likely answer is: How does the thickness of the wire affect the strength of an electromagnet.

The answer is the second option "watt." Watt is the unit of power measured by one joule per second. Watts are a amount of electrical power and measured by the rate of energy transfer between two things.

Explanation:

Fluorine has 9 electrons and electronic structures are written listing the amount of electrons in each shell/energy level starting from the first one.

The first one can hold a maximum of 2 electrons and the 2nd, 3rd and 4rth can hold a maximum of 8

Answer:

We know that force applied per unit area is called pressure.

Pressure = Force/ Area

When force is constant than pressure is inversely proportional to area.

1- Calculating the area of three face:

A1 = 20m x 10 m =200 Square meter

A2 = 10 mx 5 m = 50 Square meter

A3 = 20m x 5 m = 100 Square meter

Therefore A1 is maximum and A2 is minimum.

2- Calculate pressure:

P = F/ A1 = 30 / 200 = 0.15 Nm⁻²  ( minimum pressure)

P = F / A2 = 30 / 50 = 0.6 Nm⁻²   ( maximum pressure)

Hence greater the area less will be the pressure and vice versa.

To find the acceleration of the skateboarder, use the provided data and the equation: acceleration = (final velocity - initial velocity) / time. Plug in the values and ensure all units are consistent, then solve.

To calculate the acceleration of the skateboarder, you need to use the data given in the table and the equations of motion. Assume the data provides initial velocity (Vi), final velocity (Vf), and time (t).

The acceleration can be calculated using the formula: acceleration (a) = (Vf - Vi) / t. Make sure the velocities are in the same units and the time is in seconds to get the acceleration in meters per second squared (m/s²).

Plug in the values from the table into this equation to find the acceleration. For instance, if Vi = 2 m/s, Vf = 4 m/s, and t = 1 s, Then the acceleration would be (4 m/s - 2 m/s) / 1 s = 2 m/s².

Explanation:

Given:

v₀ = 15 m/s

a = 3.5 m/s²

t = 5.0 s

Find: v

v = at + v₀

v = (3.5 m/s²) (5.0 s) + 15 m/s

v = 32.5 m/s

The final velocity of the car, after accelerating at a rate of 3.5 m/s^2 for 5 seconds from an initial velocity of 15 m/s, is 32.5 m/s.

The car's final velocity can be calculated using the formula for acceleration: final velocity = initial velocity + (acceleration x time). Here, the initial velocity is 15 m/s, the acceleration is 3.5 m/s^2, and the time is 5.0 seconds.

Substituting these values in the formula gives: final velocity = 15 m/s + (3.5 m/s^2 x 5.0 seconds) = 15 m/s + 17.5 m/s = 32.5 m/s. So, the car's velocity after 5 seconds of accelerating at a rate of 3.5 m/s^2 is 32.5 m/s.

Explanation:

Wycleff heard a low pitch sound the whole time, so the police car must have been moving away from him.  So he was at block 1.

Lilly observed a Doppler effect (change in pitch) first.  So the car must have passed her first, so she was at block 4.

Emilia observed a Doppler effect after Lilly.  So the car passed her after it passed Lilly, so she was at block 12.

Quincy heard a high pitch sound the whole time, so the police car must have been moving toward him.  So he was at block 17.

Wycleff is on block 1, Lilly is on block 4, Emilia is on block 12, and Quincy is on block 17. Therefore, the correct option is option D.

The apparent change in frequency caused by an observer moving relative to the wave source is called as that of the Doppler effect, Frequency deviation, or simply Doppler, according to the circumstances. The phenomenon is named after Christian Doppler, the Austrian physicist who originally observed it in 1842.

The entire time, Wycleff would hear a low-pitched sound, suggesting that the police car was moving away from him. As a result, he was in block 1.

The very first thing Lilly saw was a Doppler effect (a pitch change). Due to her position in block 4, the car should really have bypassed her first.

Emilia saw a Doppler effect after Lilly. She was at block 12 whenever the car passed Lilly before overtaking her.

Quincy had been hearing a high-pitched sound the entire time, which signaled that perhaps the police car was coming. As a result, he was in block 17.

Therefore, the correct option is option D.

Before I answer I want to say this Calibri is the superior font and green is the only highlight color.

The correct answer is C: Electrons are transferred → Ions form → Ions are attracted to each other

Explanation:

Generally, an ionic compound is formed between electropositive and electronegative elements.

Normally every element wants to occupy the inert gas configuration in order to be stable. During the ionic bond formation the electropositive metal will lose the electrons and forms cation. The electronegative metal will gain electrons and forms anion.

The cation is positively charged and the ion is negatively charged. Due to the coulombic force of attraction, the ions will be attracted to each other and forms an ionic compound.

One can take the example of NaCl where Na will lose one electron and form. Chlorine will take one electron and form. These ions are attracted and sodium chloride is formed.

Hence the formation of an ionic compound follows these steps-

1- First electrons are transferred.

2-The ions are formed

3-The ions are attracted to form the compound

Explanation:

First of all, we can find the angle of the inclined plane.

We have:

L = 5 m the length of the incline

h = 1.2 m is the height

We also have the relationship

[tex]h = L sin \theta[/tex]

where [tex]\theta[/tex] is the angle of the incline. Solving for the angle,

[tex]\theta= sin^{-1} (\frac{h}{L})=sin^{-1} (\frac{1.2 m}{5 m})=13.9^{\circ}[/tex]

Now we can find the components of the weight of the box, which is the force that the box exerts on the plank. Calling W = 230 N the weight of the box, we have:

- Component parallel to the incline:

[tex]W_{par} = W sin \theta = (230 N)(sin 13.9^{\circ}) =55.3 N[/tex]

- Component perpendicular to the incline:

[tex]W_{per} = W cos \theta = (230 N)(cos 13.9^{\circ}) =223.3 N[/tex]
