The dimension formula of (X) is T and that of (Y) is T^2.

The dimension formula of (X) is T and that of (Y) is T^-2

The dimension formula of (X) is T^-1 and that of (Y) is T^2.

The dimension formula of (X) is T^-1 and that of (Y) is T^-2.​

Answers

Answer:

The dimension formula of X is T and that of Y is  T^2

Explanation:

                     d = aX + bY is ACTAULLY  [tex]S = V_{i} t + \frac{1}{2} a t^{2}[/tex]

                     so v = LT^-1

                          t = T

                          numerics do not have any dimensional formula so ignore [tex]\frac{1}{2}[/tex]

                          a = LT^-2

                          t = T^2

                         So answer for x is T and y T^2

Answers

Given parameters:

Initial speed of train  = 0m/s

Final speed  = 25m/s

time = 20s

Unknown:

Total distance covered  = ?

Solution:

Speed is a scalar quantity that has magnitude and no direction.

Mathematically;

     Speed  = [tex]\frac{distance}{time}[/tex]

  distance  = speed x time

 Input the parameters and solve for distance;

    Distance  = 25 x 20 = 500m

An escaped convict runs 1.70 km due East of the prison. He then runs due North to a friend's house. If the magnitude of the convict's total displacement vector is 2.50 km, what is the direction of his total displacement vector with respect to due East?

Answers

Answer:

The right approach will be "47° north of east".

Explanation:

The given values are:

East of prison

= 1.70 km

Displacement vector

= 2.50 km

Now,

The direction will be:

⇒  [tex]Cos \ \theta =\frac{1.7}{2.5}[/tex]

⇒            [tex]=0.68[/tex]

⇒         [tex]\theta=47.16^{\circ}[/tex]

i,e.,       [tex]\theta = 47^{\circ}[/tex] (north of east)

The direction of his total displacement vector with respect to due East is 1.83km

Resultant vector

Given the following parameters

Distance ran through east = 1.70km

displacement = 2.50km

Required

Total displacement vector with respect to due north

Using the expression below;

d = √x² + y²

2.5² = 1.7² + y²

You travel 50 meters at an angle of 37° North of East.
a) Calculate the Horizontal component.

Answers

Answer:

a)     x = 39.9 m

Explanation:

To find the components of a vector we can use trigonometric relationships. Since they indicate that the angle is 37º north of east, this angle is measured counterclockwise from the x-axis, therefore using trigonometry.

          cos θ = x / d

          sin θ = y / d

where the angle is 37º and the distance d = 50 m

          x = d cos θ

          y = d sim θ

let's calculate

        x = 50 cos 37

        y = 50 sin 37

The velocity of a vehicle reaches 4 m/s in 4 seconds. Is the velocity of the
car uniform? Explain.​

Answers

Answer:

The velocity is not uniform

Explanation:

The velocity is not uniform, since the vehicle is increasing its speed to a value of 4 [m/s] in a time of 4 [s], that is, the vehicle is accelerating to increase its velocity, so when there is acceleration the velocity can not be constant or uniform.

Vf = Vo +(a*t)

where:

Vf = final velocity = 4 [m/s]

Vo = initial velocity = 0

a = acceleration [m/s²]

t = time = 4 [s]

a = (4 - 0)/4

a = 1 [m/s²]

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

The mathematical expression for Newton's second law is as follows

F = ma

As given in the problem, two children fight over a toy. One pulls with a force of 8N to the right. The other pulls with a force of 6N to the left.

Net force = 8 - 6

Answers

Answer:

Explanation:

Suppose you increase the voltage in the coils of the solenoid of an electromagnet. the electromagnet strength becomes greater. Hence option C is correct.

What is Electromagnet ?

An electromagnet is a type of magnet where an electric current creates the magnetic field. The wire that makes up an electromagnet is often twisted into a coil. A magnetic field is produced by a current flowing through the wire and is focused in the hole in the centre of the coil. When the current is cut off, the magnetic field vanishes. In order to create a stronger magnet, the turns of the wire are frequently twisted around a magnetic core composed of a ferromagnetic or ferrimagnetic material, such as iron.

An electromagnet's key benefit over a permanent magnet is the ability to swiftly alter the magnetic field by adjusting the amount of electric current flowing through the winding. Contrary to a permanent magnet, however

Passage 1: Excerpt from Will Yellow School Buses Soon Become Rolling Ads?1 Tight school budgets could soon translate into Missouri school districts selling ad space on yellow school buses.2 Missouri state Rep. T.J. Berry, R-Kearney, says his billHB 224isnt a cure-all by any stretch. But legalizing ads inside and outside the buses would give school districts one additional way to raise money in these tough times.3 Every single school district has had to deal with budget concerns, Berry said last week. And generally speaking, the way they have had to deal with those has been cuts or tax increases.4 The school bus is something that is already out there and paid for, he said. His bill would permit districts to generate a modest stream of income from their buses.5 Few question the need for finding additional funds when it comes to educating children, but at least two groups think the school bus exteriors should remain ad-free.6 There is no such thing as free money, said Josh Golin, associate director for the Campaign for a Commercial Free Childhood. There are real costs to this: the price of selling out your students to advertisers.7 Students dont need the first and last message they receive from their schools each day to be advertisements, Golin said. Students boarding a bus are certainly a captive audience.8 The National Association of State Directors of Pupil Transportation Services opposes advertising on safety grounds. Obscuring the recognizable school-bus yellow exterior with ads and distracting other drivers present a safety problem around school buses that cannot be ignored, the group said in its position paper.9 National studies have shown that anything that diverts a drivers attention from the road can pose a hazard, opponents say.10 And a big yellow bus doesnt distract? Berry asked.11 Several years ago in Indiana, a Department of Education lawyer suggested that allowing advertisements on buses would invite First Amendment challenges by spurned advertisers, the group noted.12 Berry said the bill would limit the types of advertising that would be allowed.13 The regulations would prohibit ads that contain obscene or sexual material, or messages associated with gambling, tobacco products, alcohol, and political campaigns or causes. The ads could not promote drug use or any illegal activity or antisocial behavior. They cant contain harmful, discriminatory, false, misleading or deceptive messages.14 There are a lot of safeguards being built in, he said.15 Berry emphasized that the space reserved for the ads would be very limited, meaning toward the back of the bus.16 By 2012, nine statesArizona, Colorado, Massachusetts, Nevada, New Jersey, New Mexico, Tennessee, Texas and Utahpermitted advertising on the exterior of school buses, according to the Campaign for a Commercial-Free Childhood. Several, including Missouri, considered it last year.17 The bill made it out of the Missouri House last year but did not clear the Senate, Berry said. He acknowledged that the idea was very controversial.(questions)In Passage 1, how does the author compare the issues of tax increases and advertising on buses?A)They are both actions that require safeguards.B)They are both issues of controversy in school districts.C)They are both possible approaches to dealing with budgetary concerns.D)They are both present problems that cannot be ignored by state representatives. how many counties are in tennessee 7.
