Kinematics

That's not a valid question. 330 km is a length, not a speed. You need to know how much time it takes to travel that distance.

Please determine what you're trying to measure and post a new question.

The general answer would be "yes". However, what goes on at the singularity of a black hole is a mystery. Certainly there is mass, but what about a "size"? We don't know.

Assuming the simplest conditions (ie (1) the pendulum pivot is frictionless, (2) no air resistance for the bob's travel, etc...):

This is a problem best solved by considering the situation from an ENERGY standpoint (and not from, say, a velocity and force standpoint).

Under energy conservation (the assumption of "simplest conditions" above gives us this), the total energy (TE) remains constant. The two components contributing to the total energy in this situation are: (1) the kinetic energy (KE) and (2) the potential energy (PE).

So, TE = KE + PE

We know (hopefully) that the (simple) formula for the PE of a mass in earth's gravity is:

PE = mgh where m is the mass, g is the force of earth's gravity and h is the height above SOME (any) reference point.

We also know that the pendulum's KE at the top of its swing (in this problem, the top of the swing is when it's horizontal) is zero.

For simplicity, we'll set the reference point for all height measurements at the bottom of the pendulum's swing (ie one meter below the pendulum's point of attachment to the stand/ceiling/support whatever).

Putting all the info. above together:

At the START, TE = PE + KE = PE = mgh = 0.1 kilograms * 9.8 m/s^2 * 1 meter

= 0.98 Joules

Now at the BOTTOM of its swing, TE = PE + KE,

BUT PE is zero at the bottom of the swing (because h is zero)

AND we just computed TE above as 0.98 Joules

SO, at the swing bottom, KE = TE = 0.98 Joules

At the 30 degree from vertical mark,

Trigonometry tells us that the height, h, at 30 degrees is 1 meter - cos(30)*1 meter

= (1 - 0.8660) meters = 0.1340 meters

SO here the PE is: PE = mgh = 0.1 kilograms * 9.8 m/s^2 * 0.1340 meters

= 0.1313 Joules

AND going back to find the KE, TE = KE + PE gives us 0.98 = KE + 0.1313,

implying that KE = 0.8487 Joules

Sound waves are energy waves. All you need to do is pass them along or through something that can collect or resonate them. A microphone is a good example of a device that collects sound waves. Any drum will resonate sympathetically with one specific sound frequency passed along it's surface.

A graph that shows displacement plotted against time for a particle moving in a straight line. Let x(t) be the displacement of the particle at time t. The distance-time graph is the graph y=x(t), where the t-axis is horizontal and the y-axis is vertical with the positive direction upwards. The gradient at any point is equal to the velocity of the particle at that time. (Here a common convention has been followed, in which the unit vector i in the positive direction along the line has been suppressed. The displacement of the particle is in fact a vector quantity equal to x(t)i, and the velocity of the particle is a vector quantity equal to x(t)i.)

1 mile = 5280 ft

1 hour = 3600 seconds

105 miles/hour = (105 x 5280 ft) / (1 x 3600 seconds)

= 154 ft/s

1. Treading the wheels of vehicles

2. By increasing the weight of the object

3. By putting rubber grips on objects like cricket bats, racquets etc.

4. By having rough designs on shoes etc.

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.

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.

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

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.

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.

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.

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.

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.

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.

One kilometer per hour is equivalent to approximately 0.621 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.
