a a 10000 kg train was moving with 48m/s then starts decelerate with constant rate to stop on its stationary that is found 192m away so the train slides through this distance and stops. how long the train did takes to stops​

Answers

Answer 1

Answer:

First we need to calculate how fast it goes.

192m / 48m per second = 4 seconds

Then calculate the 4 seconds with the weight of the train.

10000 kg x 4 seconds = 40,000 seconds.

That means the train traveled 192 meters in 40,000 seconds.

How do you calculate frequency and rate?

Answers

Divide the number of times the event happens over the period of time to determine the frequency.

What is the rate of frequency?

The frequency index is the number of occupational accidents for 1,000 employees, whereas the frequency rate is the number of occupational accidents (work halted for more than one day) that occurred over a period of 12 months by one million hours worked.

Both frequency and rate count the number of times a behavior takes place. Since frequency, f, is 1/T, wave speed, frequency, and wavelength are related by the equation v = f. In contrast to frequency, rate is time-based. Calculating rate and frequency is simpler and more precise.

Nuclear processes such as "alpha decay," which releases a particle made up of two protons and two neutrons, allow unstable nuclei to transform into new elements. An alpha particle, which is just a helium nucleus, is an expelled particle that has this name. A positive charge and a sizable mass are two characteristics of alpha particles. Alpha particles can't penetrate very deeply into a material or go very far through the air due to their huge mass. Alpha decay is rarely employed in external medical radiation therapy since it only affects surfaces.

By examining how radiation is deflected by a magnetic field, Ernest Rutherford was able to distinguish alpha decay from other types of radiation in the beginning. You would anticipate a positive particle to deflect in the manner of alpha decay.

if a boat and its riders have a mass of 1200 kg and the boat drifts in at 1.7 m/s how much work does sam do to stop it?

Answers

The work done to stop the boat from the movement is 1020 J

The mass of the boat = 1200 kg

The initial velocity of the boat = 1.7 m/s

The final velocity of the boat = 0 m/s

The work done to stop the boat is the change in kinetic energy of the boat from movement to rest. It can be done by using the formula,

            W = ΔKE = 1/2mu² - 1/2mv²

where m is the mass of the boat

           u is the initial velocity of the boat

           v is the final velocity of the boat.

Let us substitute the known values in the above equation, we get

        W = 1/2 (1200)(1.7) - 1/2(1200)(0)

             = 1/2 x 1200 x 1.7

How physics is involved in air bags helpful?Your vehicle and everything inside of it are moving in one direction; therefore, for it to stop, force must be applied gradually in the other direction over time. This happens very quickly in an accident, and because the opposing force only has a little period of time to operate on the vehicle, the force is stronger. The airbag system is made to protect you from the damaging pressures that an accident can exert on you.Your airbag system is made up of three primary parts: the bag, the inflator, and the sensor.

if a ball of volume v and density is fully submerged to a depth h in water of density pw. what is the formula for the boyuant force it experiences?

Answers

The buoyant force experienced by an object fully submerged in a fluid is given by the formula:

Fb = p * g * V

where Fb is the buoyant force, p is the density of the fluid, g is the acceleration due to gravity, and V is the volume of the object.

If you are given the volume and density of the ball and the density of the water, you can use this formula to calculate the buoyant force experienced by the ball. Simply plug in the appropriate values for p (the density of the water), g (the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth), and V (the volume of the ball).

It's important to note that this formula only applies to objects that are fully submerged in the fluid. If the object is partially submerged, the buoyant force will be less than what is calculated using this formula. In this case, you would need to take into account the volume of the object that is submerged in the fluid in order to calculate the buoyant force accurately.

The time to fatigue calculated from the given record in Lab data is preferably 60 seconds.

Time to fatigue is the time that is taken for muscle contraction to decrease by 50% of its maximum strength.

Force is the one that is measured by weight here. Here, as time progresses force is seen to come down.

When force is seen to come down, there is a decrease in the number of motor units that get employed as well.

Time to fatigue is the one where this force expressed as weight reaches half of the maximum.

Here, the maximum force expressed as kg is 48kg at 0 sec.

Half of 48kg is 24kg. This is the point where time to fatigue happens with a decreased number of motor units.
