Answer:

v = 15 m / s

Explanation:

In this exercise we are given the position function

          x = 5 t²

and we are asked for the average velocity in an interval between t = 0 and t= 3 s, which is defined by the displacement between the time interval

          [tex]v= \frac{v_{f} - v_{o} }{t_{f} - t_{o} }[/tex]

let's look for the displacements

        t = 0     x₀ = 0 m

        t = 3     [tex]x_{f}[/tex] = 5 3 2

                     x_{f} = 45 m

we substitute

           [tex]v = \frac{45 -0}{3 - 0}[/tex]

           v = 15 m / s

Answer:

P = 1412.82 [Watt]

Explanation:

First we must calculate the total mass that makes up the barbell and the two free weights at each end of the barbell.

[tex]m=30+30+20\\m= 80 [kg][/tex]

Weight is now defined as the product of mass by gravitational acceleration.

[tex]w=m*g[/tex]

where:

m = mass = 80 [kg]

g = gravity acceleration = 9.81 [m/s²]

[tex]w=80*9.81\\w=784.8[N][/tex]

Now using the product of the weight by the distance traveled we can calculate the work.

[tex]W=w*d[/tex]

where:

W = work [J]

w = weight = 784.8 [N]

d = distance = 0.9 [m]

[tex]W=784.8*0.9\\W=706.41[J][/tex]

And power is defined as the relationship of work at a certain time. The potency is expressed by means of the following formula.

[tex]P=W/t\\P=706.41/0.5\\P=1412.82[W][/tex]

Answer:

The rate of change of velocity is 9.81 m/[tex]s^2[/tex].

Explanation:

By using the equation of motion, the velocity of any object in free fall at any instant, [tex]v=u+gt[/tex]

Where u (constant) is the initial velocity,

[tex]g=9.81 m/s^2[/tex] is the acceleration due to gravity,

v= velocity at time t.

To get the rate of change of velocity, differentiating the velocity, v, with respect to time, as

[tex]\frac {dv}{dt}=\frac{d}{dt}(u+gt) \\\\=\frac{d}{dt}u +\frac{d}{dt}(gt) \\\\=0+g\\\\=g[/tex]

[tex]\Rightarrow \frac{dv}{dt}=9.81 m/s^2[/tex]

Hence, the rate of change of velocity is 9.81 m/[tex]s^2[/tex].

Answer:

58,800Joules

Explanation:

The energy lost is equal to the workdone by the car as it skids.

Workdone = Force * Distance

Given

Force = 8000N

Get the distance using the equation of motion

v² = u² - 2gS

0² = 12² - 2(9.8)S

-12² =  - 2(9.8)S

-144 = -19.6S

S = 144/19.6

S = 7.35m

Calculate the required energy

Workdone = 8000 * 7.35

Workdone = 58,800Joules

Hence the energy lost due to friction is 58,800Joules

Answer:

0.39166666666

Explanation:

The temperature of the rock located at 1,000 km below the earth' surface has been 3200 degree Celsius. Thus, option D is correct.

The temperature at the earth's surface has been found to be nearly 0 degree Celsius. According to the geology of the earth, the temperature has been increased to 1500 degree Celsius by digging 100 km below the earth surface.

Thus, the temperature at 100 km from earth surface has been 1500 degree Celsius.

On moving down from 100 km, there has been a rise in temperature, and at the mouth of the mantle at 1000 km, the temperature has been approximately 3500 degree Celsius.

Thus the temperature that has been near  about 3500 degree Celsius is 3200 degree Celsius. Thus, the temperature of the rock at 1000 km below the earth surface has been 3200 degree Celsius. Thus, option D is correct.

Answer:

Vf₂ = 2 Vf₁

It shows that final speed of Joe is twice the final speed of Jim.

Explanation:

First, we analyze the final speed of Jim by using first equation of motion:

Vf₁ = Vi + at

where,

Vf₁ = final speed of Jim

Vi = initial speed of Jim = 0 m/s

a = acceleration of Jim

t = time of acceleration for Jim

Therefore,

Vf₁ = at   ---------------- equation (1)

Now, we see the final speed of Joe. For Joe the parameters will become:

Vf = Vf₂

Vi = 0 m/s

a = a

t = 2t

Therefore,

Vf₂ = 2at  

using equation (1):

Vf₂ = 2 Vf₁

It shows that final speed of Joe is twice the final speed of Jim.

Answer:

nuclear energy.............

The sun's energy begins in the nuclear form of energy. Nuclear energy is the origin of the sun's energy.

Nuclear energy originates from the sun's energy. Nuclear fusion processes happen at the sun's core, transforming protons from hydrogen into helium and releasing a tremendous amount of energy in the process. Nuclear fusion is the term for this action.

Helium nuclei are created from the collision and fusion of hydrogen nuclei in the sun's core, which experiences extremely high temperatures and pressures. An enormous quantity of energy is released during the nuclear fusion process in the form of electromagnetic radiation, especially visible light photons and other types of electromagnetic radiation.

The intense heat and brightness of the sun are maintained by the energy generated by nuclear fusion in its core, giving it a potent source of light and heat that sustains life on Earth and powers a variety of atmospheric and climatic processes.

Hence, the sun's energy begins in the nuclear form of energy. Nuclear energy originates the sun's energy.

Answer:

400N

Explanation:

Given the following parameters

Mass m = 200g = 0.2kg

initial velocity u = 48m/s

Final velocity v = 52m/s

Time t = 2.0x10-3 s.

Impulse is expressed as I = Ft = m(v-u)

Ft = m(v-u)

F =  m(v-u)/t

Substitute the given values into the formula

F = 0.2(52-48)/0.002

F = 0.2(4)/0.002

F = 0.8/0.002

F = 400N

Hence the average force of the bat on the ball is 400N

Answer:

The strength of gravity on Pluto is 0.6 m/s²

Explanation:

The given mass of the shoe = 0.5 kg

The weight of the shoe (on Pluto), W = 0.3 N

Therefore, given that weight, W = Mass × The acceleration due to gravity, We have;

The strength of gravity = The force gravity applies to each unit of mass = The acceleration due to gravity (in m/s²)

The weight of the shoe, W = The mass of the shoe × The strength of gravity on Pluto

Substituting the known values, gives;

0.3 = 0.5 × The strength of gravity on Pluto

∴ The strength of gravity on Pluto = 0.6 m/s².

Answer:

v=69.32 m/s

Explanation:

you have to transfer the distance from mile to meters (from miles to meters multiply by 1609)

so d=204387 m

you have to transfer the time from hour to second (from hour to second multiply by 3600)

so t=2948.4 s

the rule says v=d/t=204387/2948.4= 69.32 m/s

The TGV train has a speed of 69.306 meters per second.

Let suppose that TGV train is travelling at uniform velocity, then we can be calculated its speed by means of the following kinematic equation:

[tex]v = \frac{x}{t}[/tex] (1)

Where:

Now we proceed to convert both distance and time in terms of fundamental units:

Distance:

[tex]x = 127\,mi \times 1609\,\frac{m}{mi}[/tex]

[tex]x = 204343\,m[/tex]

Time:

[tex]t = 0.819\,h \times 3600\,\frac{s}{h}[/tex]

[tex]t = 2948.4\,s[/tex]

If we know that [tex]x = 204343\,m[/tex] and [tex]t = 2948.4\,s[/tex], then the speed of the TGV train is:

[tex]v = \frac{204343\,m}{2948.4\,s}[/tex]

[tex]v = 69.306\,\frac{m}{s}[/tex]

The TGV train has a speed of 69.306 meters per second.

Answer:

In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel. Colloquially, curves that do not touch each other or intersect and keep a fixed minimum distance are said to be parallel.

In a series circuit, the current that flows through each of the components is the same, and the voltage across the circuit is the sum of the individual voltage drops across each component. ... In a series circuit, every device must function for the circuit to be complete.

In a series circuit, all components are connected end-to-end, forming a single path for current flow. In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.

[tex]x =\frac{-R}{2}[/tex]

Explanation:

From the question we are told that mass

Thin layer radius [tex]= 2R[/tex]

Generally the expression for ths solution is given as

Xcm =(m*0 =m(-2R))/2m =-mR/(2m)=-R/2

the center of mass will not move at initial state  

Considering the center of mass of both bodies

[tex]xcm=\frac{m*x+m*x)}{2m} =x[/tex]

[tex]x =\frac{-R}{2}[/tex]

Therefore the enclosing layer moves [tex]x =\frac{-R}{2}[/tex]                          

The shell move from its initial contact point with the surface is,

[tex]x =\dfrac{-R}{2}[/tex]

Given-

Radius of the ball is [tex]R[/tex].

the mass of the ball is [tex]m[/tex].

The mass of the thin shell is [tex]m[/tex].

The radius of the thin shell is [tex]2 R[/tex].

For the two bodies with mass [tex]m[/tex], the center of mass can be given as,

[tex]x_{cm}=\dfrac{m_{1} x_{1}+m_{2} x_{2} }{m_{1} +m_{2}}[/tex]

In the given question, the mass of both the bodies are equal and the given distance of center of mass for both bodies are also equal. Therefore,

[tex]x_{cm}=\dfrac{m x_+mx }{m +m}[/tex]

[tex]x_{cm}=\dfrac{2mx }{2m}[/tex]

[tex]x_{cm} =x[/tex]

Distance for center of mass can also be given as,

[tex]x_{cm} =m\times o[/tex]

[tex]x_{cm} =m\times \dfrac{-R}{2m}[/tex]

[tex]x_{cm} =\dfrac{-R}{2}[/tex]

Comparing both the values of the distance of center of mass we get,

[tex]x =\dfrac{-R}{2}[/tex]

Hence, The shell move from its initial contact point with the surface is,

[tex]x =\dfrac{-R}{2}[/tex]
