What actions are permissible when you are graphically adding one vector to another?

Answers

Answer 1

Answer:

1. Which of the following actions is permissible when you are graphically adding one vector to another:

Explanation:

: move the vector, rotate the vector, change the vector's length?

Answer 2

When you graphically add one vector to another, you can only move the vector as long as you don't modify its length or the direction it points in.

What are vector quantities?

In physics, a vector is a quantity with both a magnitude and a direction. It is often represented by an arrow whose length is proportional to the magnitude of the quantity and whose direction is the same as that of the quantity.

A vector does not have position, while having magnitude and direction. In other words, a vector's shape is unaltered if it is shifted parallel to itself as long as its length is unaltered.

Hence, when you are graphically adding one vector to another, permissible action is move the vector as long as you don't modify its length or the direction it points in.

In Europe, gas cost approximately €0.98 per liter. How many dollars($) per gallon is this? ​ using a factor method

Answers

Answer:

€0.98 per liter = 4.377 doller per gallon

Explanation:

It is given that, In Europe, gas cost approximately €0.98 per liter. We need to convert it into dollars($) per gallon.

We know that, 1 euro = 1.18 United States Dollar

1 litre = 0.264172 US gallon

Cost of gas in Europe is €0.98 per liter.

[tex]0.98\ \text{euro/ liter}=\dfrac{0.98\times 1.18\ \text{doller}}{0.264172\ \text{gallon}}\\\\=4.377\ \text{doller/gallon}[/tex]

Please help me with thus question (picture) D:

Answers

well thanks for the Information

Explanation:

Torque = Force * Perpendicular distance of the force = 10N * 0.8m = 8Nm.

In diagram A, both torques are acting in a clockwise direction. Hence the net torque is 2N * 1m + 4N * 1m = 6Nm, clockwise.

In diagram B, the torques are acting in opposite directions. For the clockwise one, its torque is 5N * 4m = 20Nm. For the anticlockwise one, its torque is 2N * 10m = 20Nm. Since they are in opposite directions and are equal, they cancel out each other.

Hence net force = 0N and net torque = 0Nm.

a man pulls a box with a force of 90.0 N directed along the handle which makes angle of 45 degrees with the ground. find the horizontal and vertical components of this force

Answers

Answer:

The horizontal component of the force, Fₓ = 63.64 N

The vertical component of the force, [tex]F_y[/tex] =  63.64 N

Explanation:

Given;

magnitude of the force, F = 90 N

angle between the handle and the ground, θ = 45°

The horizontal component of the force, Fₓ = Fcosθ

Fₓ = 90 x cos45

Fₓ = 63.64 N

The vertical component of the force, [tex]F_y = Fsin \theta[/tex]

[tex]F_y[/tex] = 90 sin45

[tex]F_y[/tex] = 63.64 N

Therefore, the horizontal  and vertical components of the force is 63.64 N.

B) What is her average velocity over the entire trip?

Answers

Answer:

A.) 3.975 m/s

B.) 0.925 m/s

Explanation:

Given that a person walks first at a constant speed of 4.90 m/s along a straight line from point A to point B and then back along the line from B to A at a constant speed of 3.05 m/s.

A) What is her average speed over the entire trip?

The average speed = (4.90 + 3.05)/2

Average speed = 7.95/2

Average speed = 3.975 m/s

B) What is her average velocity over the entire trip?

Since velocity is a vector quantity, that is, we consider both the magnitude and direction

Average velocity = ( 4.90 - 3.05)/2

Average velocity = 1.85/2

Average velocity = 0.925 m/s

Explanation:

Traveling waves are disturbances of the medium that are transmitted with a constant speed, where matter is subjected to oscillations around its equilibrium point, transporting only energy.

A simile can be established with the news, where the fact that occurs is the matter of has some type of oscillation or disturbance, which occurs somewhere and is there, the news is the wave that carries the information of this fact the energy of the same to all points, therefore it is equivalent to a traveling wave.

The news is the wave that carries the information of this fact and the energy of the same to all points, making it equivalent to a traveling wave.

What is a wave?

A wave is a phenomenon that flows across a material medium without leaving any lasting mark. Mechanical or electromagnetic waves can be used to classify them.

Transverse and longitudinal are the two main forms.

The wave can be compared in the form of news as

The news is the wave that carries the information of this fact and the energy of the same to all points, making it equivalent to traveling. wave.

Traveling waves are medium disturbances that are conveyed at a constant pace, where matter oscillates around its equilibrium point, transferring only energy.

A parallel may be drawn with the news, where the fact that occurs is the issue of having some sort of oscillation or disturbance.

We have know that,

[tex]\green\bigstar\:\rm{\gray{\overbrace{\underbrace{\red{S\:=\:ut\:+\:\dfrac{1}{2}\:at^2\:}}}}}[/tex]

Where,

S = Distance .

u = initial velocity = 0m/s

t = time = 3s

a = acceleration

[Note :- Here, acceleration is ‛acceleration due to gravity’ .]

a = 10m/s^2

=> S = 1/2 × 10 × (3)^2

=> S = 5 × 9

=> S = 45m -----(1)

✒ If the ball takes n’ second to fall the ground, then distance covered in nth second is,

[tex]\green\bigstar\:\rm{\gray{\overbrace{\underbrace{\red{S_n\:=\:u\:+\:\dfrac{g}{2}\:(2n\:-\:1)\:}}}}}[/tex]

=> Sn = 0 + 10/2 (2 × n - 1)

=> Sn = 5 (2n - 1)

=> Sn = 10n - 5 -----(2)

Therefore,

10n - 5 = 45

=> 10n = 45 + 5

=> n = 50/10

=> n = 5

Now put the value of ‛n = 5’ in equation(2), we get

=> Sn = 10 × 5 - 5

=> Sn = 50 - 5

=> Sn = 45m
