Answer:

Carbon compounds regulate the Earth's temperature, make up the food that sustains us, and provide energy that fuels our global economy. Most of Earth's carbon is stored in rocks and sediments. ... These are the reservoirs through which carbon cycles.

Find the heat released in cooling 10g of water at 100C down to 25C

Reika [66]

]To calculate the amount of heat entering or leaving a system, the equation

is used.

Explanation:

m = mass (in grams)

c = specific heat capacity (J/g°C)

ΔT = change in temperature (°C)

Here, we will use the specific heat capacity for liquid water which is 4.19 J/g°C.

The mass given is 25.0 grams.

As for the change in temperature, I will assume that it start off at room temperature, 25°C.

Unlike record players which rotate at a constant angular velocity, the CD-ROM driver in a CD player rotates the CD at different

zimovet [89]

Answer:

A. 21 rad/s

B. 200.5 rpm

C. 26.46 rad/s2

D. 0.299 Hz

Explanation:

Parameters given are:

Tangential velocity,v = 1.26m/s

Diameter (outer edge) = 0.120m

Outer edge radius, ro = 0.12/2

= 0.06m

A. Calculate Angular velocity

Angular velocity, w = v/r

= v/ro

= 1.26/0.06 = 21 rad/s

In rpm,

2pi/60 rad/s = 1 rpm

1 rad/s = 60/2pi rpm

Sp, 21 rad/s = 60 * 21/2pi rpm

= 200.5 rpm

B. Calculate the inner edge radius, ri given w = 500 rpm

Converting rpm to rad/s,

= 2pi/60 * 500 rad/s

= 52.34 rad/s

ri = v/w

= 1.26/ 52.36

= 0.024m

C. Calculating centripetal acceleration, a from the outer edge, ro

a = v2/r = w2r

= (1.26)2/0.06

= 26.46 rad/s

D. Calculate the frequency, f of the outer edge angular velocity, w = 21 rad/s

f = 2pi/w

= 2pi/21

= 0.299 Hz (or per second)
