What is 106.6 kilometers per hour?
106.6 kilometers per hour is a unit of speed used to measure how far something travels in an hour. It is equivalent to 66.2 miles per hour in the Imperial system.
How fast is 40 seconds per mile?
To calculate the speed of 40 seconds per mile, you would need to divide 60 by 40 to get 1.5 minutes per mile. Converting this to hours would be 1.5 divided by 60, which is 0.025 hours per mile. This means the speed is approximately 25 miles per hour.
What is the difference between statics and dynamics in economics?
Statics in economics focuses on analyzing economic variables at a specific point in time, while dynamics looks at how these variables change over time. Static analysis typically examines equilibrium conditions, while dynamic analysis considers how variables evolve over different time periods.
Lets list out the variables, the skater has a mass of 65kg, or m1 and a velocity of 10 m/s , or v1 which gives the value for its kenetic energy k1 to be
K= .5 mv^2 = .5 (65)(10^2)= 3250 J
We set that number equal to the new equasion for the elephant
3250= .5mv^2 = .5(3000)v^2
and we solve for v getting an answer of 1.47 m/s
What would the world be like without friction?
Trivial Effects of a World Without The Limiting Force of Friction:
Automobiles, ships, and most aircraft would be useless: If you could ever get them moving, steering would be impossible, and stopping safely would be almost impossible. It would be worse than trying to move around on slick, wet ice everywhere. Everything would have to be tethered (tied down). It would be very difficult, or impossible, to pick up a coin from a flat surface. It would be difficult to pick up, and hold, a glass of water, and to keep from spilling it.
Without Friction, There Would Be No life.
There would be many other consequences as well, in a frictionless world. Everyone, and everything not tied down, would be sliding all over the place, including the water in our lakes, rivers and oceans. Gravity would become the defining force, and the continents would become unstable and easy prey to it. Indeed, life itself would quickly become doubtful at best, but almost certainly, impossible.
Others Have Said:
The world with no friction would be chaos. Nothing would stay where you put it. Everything would slide around. With friction, most things stay where you leave them, except things like a ball on a slope.
You would never feel the wind again. Meteorites would not slow down, liquefy, or break up before hitting Earth, so each would strike Earth's surface with greater mass, and more force than friction would allow.
Basketball would be really entertaining to watch, but not fun to play. Friction allows the players' shoes to grip the floor, and their hands to grip the ball. Without friction they'd be falling down all the time and they couldn't hang onto the ball, much less catch it.
In a frictionless world, if a ball were rolled (set in motion), it would never stop rolling. Walking or standing would be impossible. Obviously, everything concerning Earth's surface, and how we use it, would be very different.
The change in velocity is 35 m/s (east) - (-20 m/s) (west) = 55 m/s. The impulse required can be calculated as mass x change in velocity, which is 100 grams (0.1 kg) x 55 m/s = 5.5 Ns. The average force can be calculated as impulse / time, which is 5.5 Ns / 0.025 s = 220 N.
Why is a falling glass less likely to break on carpet?
It is the force exerted within the glass when it hits the floor that breaks it. If the glass falls on a hard floor like concrete then the force is very big because the floor has no "give." Effectively the bit of the glass that hits the floor stops instantly but the rest of the glass following behind is still moving. The force within the glass is bigger than the tensile strength of the material and so it fails. If the glass falls on a carpet then the carpet has some "give." The glass slows down over a few millimeters by squashing the carpet. This massively reduces the forces within the glass and gives it a fighting chance of staying in one piece.
How are scalar and vector quantaties alike?
Scalar and vector quantities are both used to describe physical quantities in physics. The key similarity between them is that they both involve numerical values. However, vector quantities also have a direction associated with them, while scalar quantities do not.
What feature of a distance time graph represents the direction of motion?
the velocity and acceleration
Not really. The direction is implied by the description of the distance axis, so as you go to the right on the graph it represents greater distance from the point which you have chosen to represent your point of reference. So you could define it for example as the distance east of your start point, or the distance north from your start point, or just the distance in any direction etc. If your description does not specify a direction, then all you can say is how far from the start you are, with no other information on compass direction etc.
Which would be 40.39 miles per hour, if that provides a helpful reference. If, on the other hand, you're inquiring about off-road motorcycles, then we've all misread your question and we can tell you that the KTM 65 is pretty fast.
Yes. Light has a speed, electric impulses from the retina to the brain have speeds and the neurons in the brain have speeds.
What relationship exists between height and potential energy if mass is held constant?
The relationship between height and potential energy is directly proportional when mass is held constant. As an object is raised to a higher height, its potential energy increases. This relationship is given by the equation: potential energy = mass x gravity x height.
Is dimensionally correct equations necessarily be a physical relation?
No, not all dimensionally correct equations represent physical relationships. Dimensional analysis focuses on the units of measurements in an equation to ensure consistency but does not guarantee the physical relevance of the relationship itself. It is possible to have dimensionally correct equations that do not have a meaningful physical interpretation.
The object's instantaneous acceleration is (8t - 8) at any time.
We can't calculate the average acceleration, because you haven't defined a period
of time over which to average it. We need the start and finish times in order to
find an average.
How many mph equal one kilometer per hour?
One kilometer per hour is equivalent to approximately 0.621 miles per hour.
How do you convert 55 feet per second to miles per hour?
To convert 55 feet per second to miles per hour, you would first need to convert feet to miles by dividing by 5280 (since 1 mile = 5280 feet). Then, multiply the result by 3600 (since there are 3600 seconds in an hour) to get the speed in miles per hour. In this case, 55 feet per second is approximately equal to 37.5 miles per hour.
When the temperature of the room increased then the energy of semiconductor?
When the temperature of the room increases, the energy of a semiconductor also increases because more electrons are excited to higher energy levels. This can increase the conductivity of the semiconductor due to increased electron mobility. However, at very high temperatures, the semiconductor may experience thermal runaway and exhibit decreased performance due to excessive generation of electron-hole pairs.
The terms scalar and vector are used for units of measure, not for arbitrary abstract concepts. Would you consider "life" a unit of measure?
-------------
Acknowledging that this is nonsense to begin with ... A vector is a force with direction. And since life is a force and moves only in one direction I'd say it is a Vector.
23.02 miles per hour. A knot is a unit of measure for 1 nautical mile per hour. 1 knot=1.151 MPH.

What is watts indicator mechanism?
A Watt's indicator mechanism (also known as Watt's straight line mechanism or double lever mechanism) which consists of four links. The four links are : fixed link at A, link AC, link CE and link BFD.
The displacement of the link BFD is directly proportional to the pressure of gas or steam which acts on the indicator plunger.
The misplaced modifier in the sentence is "Around the corner." It should be placed next to the word it is modifying, most likely "sign," to clarify that the sign, not the corner, reads forty-five miles per hour.
Is 2 pounds of strawberries a scalar or vector?
2 pounds of strawberries is a scalar quantity because it represents just the amount or magnitude of strawberries, without any direction associated with it. Vector quantities would involve both magnitude and direction.
The bus will stop first. This is because the bus has more mass compared to the car, so it will experience a smaller acceleration for the same force applied. Therefore, it will take more time for the bus to come to a complete stop compared to the car.
Can a body posses two velocities at a specific time?
For different observers (moving at different velocities), the object will have different velocities (relative to the corresponding observer). For one and the same observer, the body will have only one velocity at any given time.
