Approximately how many kelvins are equal to 60°f? <br> a. 333 <br> b. 323 <br> c. 413 <br> d. 289

Afina-wow [57]

D. 289
Take the formula:
K=5/9(Fahrenheit-32)+273
Plug in Fahrenheit
K=5/9 (60-32)+273
From here it is simple math and you can plug it into your calculator getting 288.5555556 and round to 289

A cyclist acceleration from 0m/s to 8m/s in 3second. what is his acceleration?

umka2103 [35]

Answer:

2.66 m/s² .

Explanation:

Initial velocity , u = 0 m/s

Final Velocity , v = 8 m/s

Time Taken , t = 3 s

So , Acceleration = (v-u)/t = (8 m/s - 0 m/s) /3 sec . = 8/3 m/s² = 2.66 m/s²

Suppose 310. grams of ethanol (ethyl alcohol) is in an aluminum cup of 90.0 grams. Both of these are at 30.0C. A mass m of ice a

Ira Lisetskai [31]

Answer:

Explanation:

Given

mass of ethanol $m_e=310\ gm$

mass of aluminium cup $m_{al}=90\ gm$

both are at an initial temperature of $T_i=30^{\circ}C$

specific heat of ethanol $c_e=2.46\ J/g-K$

specific heat of aluminium $c_{al}=0.9\ J/g-K$

specific heat of ice $c_i=2.108\ J/g-K$

specific heat of water $c_w=4.184\ J/g-K$

Latent heat of fusion $L=334\ J/gm$

suppose m is the mass of ice added

Heat loss by Al cup and ethanol after $18^{\circ}C$ is reached

$Q_1=(310\times 2.46+90\times 0.9)\cdot (30-18)$

Heat gained by ice such that ice is melted and reached a temperature of $18^{\circ}C$

$Q_2=m\times 2.108\times (8.5)+m\times 334$

Comparing 1 and 2 we get

$m=23.65\ gm$

Thus 23.65 gm of ice is added
