Athens, Greece, was the sentimental favorite to host the centennial games, and tension was palpable as IOC President Juan Antonio Samaranch made the announcement back on Sept. 18, 1990.

"The International Olympic Committee has awarded the 1996 Olympic Games to the city of ... Atlanta," Samaranch revealed.

That announcement launched more than $1 billion of construction projects, from Olympic venues to housing for the athletes. Now, on the 15th anniversary of the games, Atlanta sees both gains and losses from the international event. Bringing the 1996 Summer Olympic Games to Atlanta was a long shot.

One of the most prominent legacies of the games is Centennial Olympic Park in the heart of Atlanta. The 21-acre plaza glistens in what was an area of urban decay, and children run and linger in the fountain.

Harvey Newman, a professor of public policy at Georgia State University, says the park brought economic development downtown.

"The area surrounding the park has added major hotels, condominiums, new office structures and, of course, people continue to flock to enjoy the Olympic rings fountain," Newman says.

A string can withstand a force of 135 N before breaking. A 2.0 kg mass is tied to the string and whirled in a
horizontal circle with a radius of 1.10 m. What is the maximum speed that the mass can be whirled at before
the string breaks?

Answers

The mass would have centripetal acceleration a given by

a = v ² / R

where

v = tangential speed of the mass

R = length of the string

By Newton's second law, a maximum tension of F = 135 N would apply an acceleration of

135 N = (2.0 kg) a   →   a = 67.5 m/s²

which requires a tangential speed v of

67.5 m/s² = v ² / (1.10 m)   →   v = √((67.5 m/s²) (1.10 m)) ≈ 8.62 m/s

Why do we add the masses together after that inelastic collision?

Answers

Answer:An inelastic collision is one in which the internal kinetic energy changes (it is not conserved). A collision in which the objects stick together is sometimes called perfectly inelastic because it reduces internal kinetic energy more than does any other type of inelastic collision.People sometimes think that objects must stick together in an inelastic collision. However, objects only stick together during a perfectly inelastic collision. Objects may also bounce off each other or explode apart, and the collision is still considered inelastic as long as kinetic energy is not conserved.

Answers

If a car is traveling 103 miles per hour, how many miles and how much time would it take for another car to catch up to them from a complete stop?

Answers

Answer:

Required distance is 103 miles and the required time is 1 hour

Explanation:

Given;

speed of the car, v = 103 miles per hour

Speed is the given as the ratio of distance traveled to time taken for the motion.

The distance it will take another car to catch up to them from a complete stop is 103 miles and the time it will take the car is 1 hour.

Therefore, required distance is 103 miles and the required time is 1 hour.

The temperatures on the surface of the Moon vary much more than those on Earth because the moon has no atmosphere (third answer in the list), and therefore there are no molecules that could retain residual heat and make the change from day to night a softer transition.

Why did you need a permanent magnet? What do you think would happen if you increased the
number of permanent magnets? (dc motor)

Answers

Permanent magnets are important for their industrial uses especially when it comes to power generation and electric motors. The induction process for turbines and generators needs permanent magnets to turn mechanical motion into energy.

Exposing magnetized magnets to opposing external fields produces a demagnetizing effect. This effect is most apparent in permanent magnet materials having a non-linear demagnetization curve, such as Alnico. ... Other factors such as SHOCK and VIBRATION have very little effect on today's permanent magnet materials.

There is a bell at the top of a tower that is 45m high. The bell mass is 190. Calculate its potential energy.

Answers

Answer:

83790 J.

Explanation:

Potential Energy: This can be defined as the energy possessed by a body, by vitue of it position in the gravitational field. The S.I unit of Potential Energy is Joules (J).

From the question,

P.E = mgh........................................... Equation 1

Where P.E = potential Energy of the bell, m = mass of the bell, h = height of the tower, g = Acceleration due to gravity.

Given: m = 190 kg, h = 45 m.

Constant: g = 9.8 m/s²

Substitute these values into equation 1

P.E = 190×45×9.8

P.E = 83790 J.

Hence the potential energy of the bell is  83790 J.

The compass is a small bar magnet that’s free to spin. Based on what you observed, is the coil of wire with current passing through it a magnet?

Answers

Answer:

People have been aware of magnets and magnetism for thousands of years. The earliest records date back to ancient times, particularly in the region of Asia Minor called Magnesia—the name of this region is the source of words like magnet. Magnetic rocks found in Magnesia, which is now part of western Turkey, stimulated interest during ancient times. When humans first discovered magnetic rocks, they likely found that certain parts of these rocks attracted bits of iron or other magnetic rocks more strongly than other parts. These areas are called the poles of a magnet. A magnetic pole is the part of a magnet that exerts the strongest force on other magnets or magnetic material, such as iron. For example, the poles of the bar magnet shown in Figure 20.2 are where the paper clips are concentrated.

A bar magnet with paper clips attached to it.

Figure 20.2 A bar magnet with paper clips attracted to the two poles.

If a bar magnet is suspended so that it rotates freely, one pole of the magnet will always turn toward the north, with the opposite pole facing south. This discovery led to the compass, which is simply a small, elongated magnet mounted so that it can rotate freely. An example of a compass is shown Figure 20.3. The pole of the magnet that orients northward is called the north pole, and the opposite pole of the magnet is called the south pole.

Answer:

Yes, the coil of wire with current passing through it is a magnet.

Answers

Answer:

1. v₂ = 12.43 m/s

2. I₁ = - 80 N.s

3. I₂ = 80 N.s

Explanation:

Consider the following data given in the question:

m₁ = mass of the Cart 1 = 16 kg

m₂ = mass of the Cart 2 = 7 kg

u₁ = velocity of cart 1 before collision = 4 m/s

u₂ = velocity of cart 2 before collision = 1 m/s

v₁ = velocity of cart 1 after collision = - 1 m/s

v₂ = velocity of cart 2 after collision = ?

1.

Applying the law of conservation of momentum:

[tex]m_{1}u_{1} + m_{2}u_{2} = m_{1}v_{1} + m_{2}v_{2}\\(16\ kg)(4\ m/s)+(7\ kg)(1\ m/s)=(16\ kg)(-1\ m/s)+(7\ kg)(v_{2})\\v_{2} = \frac{87\ kg.m/s}{7\ kg}[/tex]

v₂ = 12.43 m/s

2.

Impulse of cart 1 = I₁ = m₁(v₁ - u₁)

I₁ = (16 kg)(- 1 m/s - 4 m/s)

I₁ = - 80 N.s

3.

Impulse of cart 2 = I₂ = m₂(v₂ - u₂)

I₂ = (7 kg)(12.43 m/s - 1 m/s)

I₂ = 80 N.s

What is the energy required to change 600g of liquid into steam if the specific heat latent is 4000 J/kg

Answers

Answer:

2400 J

Explanation:

Latent heat: This is also called hidden heat, it is the heat that is not detectable by the thermometer.

From the question,

Q = cm.................. Equation 1

Where Q = Energy, c = specific latent heat of the liquid, m = mass of the liquid.

Given: c = 4000 J/kg, m = 600 g =( 600/1000) kg = 0.6 kg

Substitute these values into equation 1

Q = 4000×0.6

Q = 2400 J

Hence the energy required is 2400 J

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the Concept of the Force.

Force = Mass * Acceleration.

here, Mass = 45 kg and Force = 65 N

hence, Acceleration = 65/45

===> Acc. = 1.44 m/s^2

hence the acceleration is 1.44 m/s^2
