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.

A box decelerates as it moves to the right along a horizontal surface as shown in the
diagram.

Which vector best represents the direction of the force of friction on the box?

Answers

The direction of the vector of motion on the right then the direction of the force of friction on the box will be toward the left. Therefore, option D is correct.

What is frictional force?

Frictional force can be defined as the force generated by two surfaces coming in contact and sliding against each other. These forces are affected by the position of the object, surface texture, and angle.

Friction can be explained as the force that prevents the movement of the moving object when the surface of one object comes in contact with another.

The fractional force acting on an object can be represented as:

F = μmg

In the given diagram the box is moving in the right direction, Then the force of friction will act in the opposite direction. Therefore the vector in the left direction represents the direction of the force of friction on the box.

Answers

The position of the image of a cologne bottle is equal to 52cm. The magnification of the image is equal to 0.55 and the virtual image.

What is the mirror formula?

The reflecting part of the concave mirror is that which caves inwards and the reflecting part of a convex mirror is one which caves outwards.

[tex]\displaystyle \frac{1}{f}=\frac{1}{u}+\frac{1}{v}[/tex]

Where f is the focal length, u is the object distance and v is the image distance

Given, the focal length of the concave mirror, f = 33.0cm

The distance of the bottle, u = 93 cm

[tex]\displaystyle \frac{1}{33}=\frac{1}{93}+\frac{1}{v}[/tex]

1/v = 0.030- 0.0107

1/v = 0.0192

v = 52 cm

An object experiences pushes or pulls as a result of its interaction with another object. There is a force operating on each object whenever there is an interaction between two items. There is no force acting on the two objects when the interaction ends.

There are four basic factors at work. Strong nuclear force, electromagnetic force, and gravitational force. The enormous nuclear force is the most potent of these four forces. This leads us to the conclusion that an object moves more quickly whenever the force acting on it is in the same direction as its motion.

How long will it take for a radioactive sample to decrease to 10% if its half-life is 22 years?

Answers

If the half-life of a radioactive sample is 22 years, it will take 73.11 years for the sample to decay to 10%.

How is half-life used to calculate radioactive decay?

A fixed percentage of activity is lost during radioactive decay per unit of time. Half-life: The amount of time needed for a sample to degrade to 50% of its starting state. 1/2 = e –(λ*T1/2). constant over time and unique to each nuclide.

Do longer half-lives imply a lower radioactivity?

The term (physical) half-life refers to the amount of time needed for radioactivity to decline and split in half.

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.

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,

where m is the mass of the boat

           u is the initial velocity of the boat

           v is the final velocity of the boat.
