a 230-newton box rests on a plank 5 meters long. One end is 1.2 meters higher than the other end. Find the components of the force the box exerts

Answers

Answer:

55.3 N, 223.3 N

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]

A vector has an x-component
of -309 m and a y-component
of 187 m.
Find the magnitude of the
vector.

Answers

Explanation:

The magnitude of a vector v can be found using Pythagorean's theorem.

||v|| = √(vₓ² + vᵧ²)

||v|| = √((-309)² + (187)²)

||v|| ≈ 361

You can find the angle of a vector using trigonometry.

tan θ = vᵧ / vₓ

tan θ = 187 / -309

θ ≈ 149° or θ ≈ 329°

vₓ is negative and vᵧ is positive, so θ must be in the second quadrant.  Therefore, θ ≈ 149°.

Explanation:

The correct answer is D

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.

A block of size 20m x 10 mx 5 m exerts a force of 30N. Calculate the
maximum & minimum pressure exerted by the block on ground?hello yeah tell me the answer of this question ​

Answers

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.

Four different observers are standing in a straight line on a street and hear a siren from a police car. Each person recorded their observations in the chart shown.



If the people are all lined up on the street at different blocks, and the police siren starts at block 3, which statement describes what block each person is standing at?

Wycleff is on block 1, Lilly is on block 4, Quincy is on block 12, and Emilia is on block 17.
Lilly is on block 1, Wycleff is on block 4, Quincy is on block 12, and Emilia is on block 17.
Lilly is on block 1, Wycleff is on block 4, Emilia is on block 12, and Quincy is on block 17.
Wycleff is on block 1, Lilly is on block 4, Emilia is on block 12, and Quincy is on block 17.

Answers

Answer:

D

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.

What is doppler effect?

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.

The acceleration due to gravity is ____.

Answers

The acceleration which is gained by an object because of gravitational force is called its acceleration due to gravity. Its SI unit is m/s2. Acceleration due to gravity is a vector, which means it has both a magnitude and a direction. The acceleration due to gravity at the surface of Earth is represented by the letter g. It has a standard value defined as 9.80665 m/s2.[ However, the actual acceleration of a body in free fall varies with location. (Wikipedia)

The acceleration due to gravity is  9.89 m / s2.

Explanation:

Gravity was discovered by Newton when he was sitting under a tree and was watching an apple reaching the ground instead of going upwards. He fond that there is a gravitational pull attached to the ground of the earth which makes all the objects towards the ground. It is represented by 'g' and its value is equal to 9.8 m /s2.

Final answer:

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.

Explanation:

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.

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:

Area = 0.25 m^2.

Thus the pressure

= Force / Area

= 150 N / 0.25 m^2

= 150/0.25  N/m^2

Answers

an electrons transferred and compound forms

Answer:

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
