How do you convert dollars per hour into cents per minute?

To convert dollars per hour to cents per minute, first calculate the number of cents in a dollar (100 cents). Then divide the dollars per hour by 60 (number of minutes in an hour) to get cents per minute. For example, if someone earns $12 per hour, the conversion would be 12 / 60 = 0.2 cents per minute.

When temperature increases the kinetic energy of the particlles decreases true or false?

No. In gases, 'Absolute temperature' is proportionally related to the kinetic energy of the particles. Therefore, increase in temperature results in increase in the kinetic energy of the particles.

80 mph to kmph?

85 kph to mph simple formula multiply kilometers x .625 or 5/8 your answer should be 53.125 mph.

How is it possible for a car to have an average velocity of zero and an average speed of 65 mph?

If the car has an average speed of 65 mph, when it returns to its starting point, it will have a displacement of zero and an average velocity of zero, because velocity has both speed and direction.

When you are driving at 50 mph you will need a stopping distance of?

The stopping distance when driving at 50 mph can vary based on factors such as road conditions and vehicle weight. As a rough estimate, the average stopping distance at 50 mph is around 175-225 feet. It is important to maintain a safe following distance and be prepared to brake gradually to avoid collisions.

How is kinetic energy affected by a change in velocity?

Kinetic energy is directly proportional to the square of the velocity of an object. This means that as the velocity of an object increases, its kinetic energy increases exponentially. Conversely, if the velocity decreases, the kinetic energy will decrease accordingly.

Is the food you eat potential or kinetic energy?

The food energy that can be utilized by the eater of the food is chemical potential energy.

In a food fight, when the food is propelled through the air, it temporarily acquires some

kinetic energy as well, which has nothing to do with its identity as food, and can't be utilized

by eating the food, since it must come to rest before the eating commences.

________

All matter is made up of a combination of kinetic and potential energy. The kinetic energy that comprises your food is all the energy of motion of its molecules. The hotter your food, the faster its molecules are moving and the more kinetic energy they posess. Also, as mentioned above, if you throw your food, it will posess bulk kinetic energy.

However, the majority of the energy contained within food is potential energy stored within what you could think of as unhappy chemical bonds. When you eat food, your body invests a little energy to break apart these unhappy bonds and makes new, happier bonds between the food molecules and the oxygen you breathe. When these happy bonds form, a large ammount of energy is released. Your body uses this energy for running around and having food fights.

Is energy in motion called kinetic energy true or false?

Yes,

Kinetic Energy is motion. When particles are warmed or heated they move faster, hit harder, and bump into each other more often.

Or for example, friction creates heat when an object rubs against another very quickly. So if the kinetic energy is higher then there is a higher chance of heat production.

A.K.A - Motion

Energy in Motion is Kinetic Energy

Its the same thing.

Does a small horse has the same amount of kinetic energy as a larger horse moving at the same speed?

The more massive horse that is moving at the same speed will have greater kinetic energy.

How do you define large and small? A small fat horse may have more mass than a large skinny horse.

30 miles per hour expressed as feet per minutes?

1 mile (mi) = 5280 feet (ft)

50 mi = 264,000 ft

50 mi/hour = 50/60 mi/min

264,000 ft/hour = 264,000/60 ft/min = 4,400 ft/min

What is the name given to the physical quantity which can be completely described by specifying both magnitude and direction. name four such quantities?

That's a 'vector'. Examples include displacement, velocity, acceleration, force,

momentum, torque, gradient, divergence, and curl.

Distance, speed, temperature, price, weight, energy, power, voltage, resistance,

and duration are not vectors.

How fast are roy Jones jr punches in mph?

that impossible to answer but just think very fast one of the fastest if not the fastest punchers ever

What is the length from the fulcrum to the load?

That is the distance between the load and the fulcrum. The load may be on the far side, or the near side of the fulcrum.

One often overlooked fact, is that as the distance from load to fulcrum increases, the load on the fulcrum decreases.

How many kph is 80mph?

80MPH is faster. 80 kph or km/h converts to 49.7096954 mph.

How much is 61 mph in kmh?

61 miles per hour is 98.17 kilometers per hour.

What is the important characteristics of the position time graph?

Given a position vs. time graph, all sorts of analyses can be done. The slope through two points on the graph represents the change in position over the change in time, or the velocity. More precisely, this is equal to dx/dt where x models position and t is time. This is known as the derivative of the function.

Moreover, we can take d2x/dt2 (the second derivative) to obtain acceleration, another useful thing to know.

How fast is 42kmh in mph?

54 km per second is equal to 120,794.56 mph

How many MPH are in 70cc?

A measurement of 70cc refers to the volume of a cylinder in cubic centimeters, not a speed measurement like miles per hour. To calculate speed in miles per hour (MPH), you would need additional information such as engine power, gearing, and other factors.

How many meter per second in 2 fps?

2 feet per second = 0.6096 meters per second.

Is true that absolute value of speed equals velocity?

No, you've got it backwards. The absolute value of velocity equals speed. Velocity is speed with a direction; speed is just a number, without regard to direction.

How many miles is 140km per hour?

140 km per hour is equivalent to approximately 87 miles per hour.

How does height change the potential energy of an object?

Potential energy = mass * gravity * height

Ep=mgh

You should know the mass of the object and gravity as 9.81.

So rearranging the formule Ep/mg=h.

Potential energy / (mass * gravity) = height.

How fast is the wind blowing at 35km per hour?

At 35 km per hour, the wind is blowing at approximately 21.74 miles per hour.

Why did one barbell have potential energy while the other did not?

The barbell with potential energy was raised to a certain height, which gave it gravitational potential energy due to its position relative to the ground. The other barbell did not have potential energy because it was resting on the ground and its position did not allow for any stored energy.

What is the kinetic energy of a 60-kg diver falling at 10 ms?

The kinetic energy of the diver can be calculated using the formula: KE = 0.5 * mass * velocity^2. Plugging in the values for the mass (60 kg) and velocity (10 m/s), we get KE = 0.5 * 60 * 10^2 = 3000 J. Thus, the kinetic energy of the 60-kg diver falling at 10 m/s is 3000 Joules.
