Its 50 points for me but ok 100 4 u nice uh... here. Bringing the 1996 Summer Olympic Games to Atlanta was a long shot. 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. 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.

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.

You are spinning a rock, of mass 0.75 kg, at the end of a string of length 0.86m in a vertical circle in uniform circular motion

Nina [5.8K]

Answer:

v (minimum speed) = 2.90 m/sec.

$\\ \\ maximum speed (v)= 6.57 m/sec.\\$

Maximum value of speed will occur at lowest point of vertical circle.

Explanation:

a) What minimum speed is necessary so that there is no tension in the string at the top of the circle but the rock stays in the same circular path?

Using the force balance expression at the top of the circle,

Gravitational Force + Tension force = Centrifugal force

$m*g + T = m*v^2/R$

Given that : T = 0

R = length of string = 0.86 m

mass of the spinning rock = 0.75 kg

$v = \sqrt{g*R}$

$v = \sqrt{9.81*0.86}$

v (minimum speed) = 2.90 m/sec.

b) what is the maximum speed the rock can have so that the string does not break?

Here the force balance at bottom of circle is represented by the illustration:

$T = m*g + m*v^2/R$

Given that:

maximum tension T = 45 N

maximum speed v = ??

mass m = 0.75 kg

∴

$45 - 0.75*9.81 = 0.75*\frac{v^2}{0.86} \\\\v^2 = 0.86*(45 - 0.75*9.81)/0.75 \\ v = \sqrt{0.86*(45 - 0.75*9.81)/0.75\\ maximum speed (v)= 6.57 m/sec.\\$

At what point in the vertical circle does this maximum value occur?

Maximum value of speed will occur at lowest point of vertical circle.

This is so because at the lowest point; the tension in string will be maximum.

15) A 1720 kg car accelerates at a rate of 3.0 m/s2. How much force is the car's engine producing? (use the formula F=ma

Anastasy [175]

Answer:

<h3>The answer is 5160 N</h3>

Explanation:

To find the force acting on an object given it's mass and acceleration we use the formula

<h3>Force = mass × acceleration</h3>

From the question

mass = 1720 kg

acceleration = 3.0 m/s²

We have

Force = 1720 × 3

We have the final answer as

Hope this helps you

Calculate the rate of heat conduction through a layer of still air that is 1 mm thick, with an area of 1 m, for a temperature of

max2010maxim [7]

Answer:

The rate of heat conduction through the layer of still air is 517.4 W

Explanation:

Given:

Thickness of the still air layer (L) = 1 mm

Area of the still air = 1 m

Temperature of the still air ( T) = 20°C

Thermal conductivity of still air (K) at 20°C = 25.87mW/mK

Rate of heat conduction (Q) = ?

To determine the rate of heat conduction through the still air, we apply the formula below.

$Q =\frac{KA(\delta T)}{L}$

$Q =\frac{25.87*1*20}{1}$

Q = 517.4 W

Therefore, the rate of heat conduction through the layer of still air is 517.4 W

100 °C is a greater temperature than which of the following?

ohaa [14]

When somebody hands you a Celsius°, it's easy to find the equivalent Fahrenheit°.

Fahrenheit° = (1.8 · Celsius°) + 32° .

So 100°C works out to 212°F.

It's also easy to find the equivalent Kelvin. Just add 273.15 to the Celsius.

So now you can see that 100°C is equal to A and D,
and it's less than B .

The only one it's greater than is C .
