Kinematics

According to Archemedes' Principle, when a body (solid) ispartially or fully immersed in a liquid then the body loses a part of its weight. The weight lost by the body is equal to the volume of liquid displaced by the solid body.

In order to compare the density of water and coke, you have to immerse a solid object in water and note down the apparent decrease of weight of the object. Then we have to immerse the same object in coke and note down the apparent decrease in weight of the object. The ratio of these two readings is equal to the ratio of weights of equal volume of water and coke. Hence, it is equal to the ratio of densities of water and coke.

The simple answer to this is, you can achieve very high velocity. The limiting factor is the speed at which what ever fuel is used is ejected from the rear of the spaceship. The speed of the spaceship's forward motion could only equal that of the fuels ejection at the rear. At this points the forces would be equal and acceleration would stop.

Yes, heat is a form of energy that is transferred from one object to another due to a difference in temperature. It can be transferred through conduction, convection, or radiation.

According to the Stefan-Boltzmann law, the energy radiated per unit area per unit time (power) of a black body is proportional to the fourth power of its temperature in Kelvin. Therefore, if you double the Kelvin temperature of a hot piece of steel, it will radiate 16 times more energy per second (2^4 = 16).

The light produced by fluorescent lights is radiant energy. It is in the form of electromagnetic radiation that is visible to the human eye.

0.83333. A meter per second is a unit of speed. One meter per second is exactly 3.6 kilometers per hour, or about 2.237 miles per hour.

An energy resources are ways of getting energy. For example we get energy (electricity) from the wind. We get energy from the wind by using wind turbines. You can also get energy from biomass and coal. Hope this helps!

if we assume an example of crank slotted lever mechanism then if we consider only the part where we are not considering the cause of motion but the effect of motion. like we are looking for the motion we are just making rotary motion to linear motion, if we are interested we can find out the velocity and acceleration factor ram over linearly moving part.

so in one word we can say that kinematics is not a consideration with cause of motion but the effect of motion.

No, 1 m/s^2 means that an object's velocity is increasing by 1 meter per second every second. So, in the first second, the velocity of the object will be 1 m/s, in the second second, it will be 2 m/s, and so on. The acceleration is constant and the velocity increases linearly with time.

The limited top speed of a 2004 dodge ram 5.7L hemi is 170km/h

* A scalar is just a number, used to represent the magnitude of something. thus, 35 is a scalar number that can mean that something is 35 inches long, 35 meters high, 35 years old, or etc. * A vector is a magnitude that has a direction. usually this is represented by magnitudes on axes that are perpendicular to each other. so, the vector ( 5 7 ) (usually written with the 5 over the 7, but the software here won't handle that) means the line from (0,0) to (5,7). notice that this line has both a magnitude (length) and a direction: i.e., it points in a different direction than the vector ( 7 5 ) but has the same magnitude, and points in the same direction as the vector ( 10 14 ) but has a different magnitude. * A tensor is a vector that has a position in space. vectors (by definition) all begin at the origin (0,0); tensors are constructed the same way but can have their origin anywhere.

One formula for force is Newton's Second Law of Motion: Force = Mass * Acceleration or F = ma

On the earth's surface, F=mg

where

F= weight

m= mass

g= acceleration due to gravity

In fact, force is the rate of change of momentum and is given by:

F = dp/dt

where p is momentum.

F = dp/dt can be expanded to F = v(dm/dt) + m(dv/dt)

where m is mass, v is velocity.

F = m(dv/dt) = ma. This is for constant mass.

F = v(dm/dt) is used when velocity is constant but mass is changing.

If an object covers equal distance in equal intervals of time, we can say that the object is moving with a uniform speed. E.g. consider an object moving along straight line. Let it travel 5 m in the first second, 5 m more in the next second, 5 m in the third second and 5 m in the fourth second. In this case, the object covers equal distance in equal intervals of time so we can say that the object is moving with a uniform speed.

If an object's velocity changes -- if its speed increases or decreases or if its direction changes -- that means it has accelerated. For an object to accelerate, the sum of the forces acting upon it must be non-zero. So, in other words, forcechanges an object's velocity.

Millions of classroom experiments would indicate that there is, in fact, a difference, but it is most likely caused by dirt, oil, and imperfections on the surfaces. When care is taken to ensure the surfaces are uniform and clean, the difference between static and dynamic friction disappears.

given distance- 200km

time-5 hours

speed- distance/time

200/5

40km/hr

Divide distance by time for speed

Divide speed by distance for time

Multiply speed and time for distance

Those are three ways to make sure you have it right

Average Velocity = (change in position) / (elapsed time)

Instantaneous Velocity = [limit as elapsed time approaches 0] (change in position) / (elapsed time)

Velocity is measured in m/s+ direction

Speed does not increase the weight of a moving body. Weight is determined by the mass of the object and the force of gravity acting on it, and it remains constant regardless of speed. Speed only affects the kinetic energy of the body, which is proportional to the square of the speed.

It would take approximately 16.67 minutes to travel 1000 miles if you are traveling at 1 mile per second. This calculation is based on dividing 1000 miles by 60 seconds (which equals 16.67 minutes).

A body is said to move with uniform velocity if it has no acceleration. This implies that the body moves with a constant speed along a straight line path.

This also means that the body moves with equal displacements in equal intervals of time, however small these time intervals may be.

If it sounds like rocks in a can, or like a Diesel engine, you might be experiencing detonation, which is really bad. It is caused by poor gas and/or ignition timing too advanced. Left unfixed, it will melt holes in your pistons.

To fix, get higher-octane fuel and/or retard timing

V = Vo + at

X - Xo = Vot + .5at2

v2 = vo2 + 2a(X - Xo)

X - Xo = .5(Vo + V)t

V is final velocity in units of meters per seconds (m/s)

Vo is initial velocity in units of meters per seconds (m/s)

a is acceleration in units of meters per squared seconds (m/s2)

t is time in seconds (s)

X is final displacement in units of meters (m)

Xo is initial displacement in units of meters (m)

Multiple unknowns can be solved for each other by using more than one equation. If you are solving for two components, find a common piece (such as time), solve for that piece for each component and set them equal to each other to solve for the other unknowns.

Hope this helps!

p.s. sometimes it is easier to remember the second, third and fourth equations as

2. df - dI = vIt + .5at2

3. v2=vI2+2a(df - di)

4. df - dI = .5(vI + vf)t

its all the same except x has been switched with the first letter of displacement, and the 0 have been switched with i for initial. f is for final

Friction provides grip and traction between surfaces, enabling us to walk, drive, and perform various tasks. It also allows us to control the speed of objects and prevent slipping or sliding. Additionally, friction helps in converting kinetic energy into heat, which can be useful in machines and brakes.
