Answer:

3000 Joules

Explanation:

as you mentioned, w=fd

where w is the work done, in this scenario in the unit of Joules

the force, or f, is given to be 300N

the distance, or d, is given to be 10m

because joules is simplified to Newtons times Meters, all we need to do in this case is plug the givens into the equation.

so, 300 Newtons x 10 Meters = 3000 Joules

Suppose you have a 0.10 M solution of AlBr3. What is the concentration of each ion? A. 0.10 M Al3+ ions and 0.30 M Br- ions B. 0

podryga [215]

Answer: The concentration of $Al^{3+}$ ions is 0.10 M and that of $Br^-$ ions is 0.30 M

Explanation:

We are given:

Concentration of $AlBr_3$ = 0.10 M

The chemical equation for the ionization of aluminium bromide follows:

$AlBr_3\rightarrow Al^{3+}+3Br^-$

1 mole of aluminium bromide produces 1 mole of aluminium ions and 3 moles of bromide ions

So, concentration of aluminium ions = 0.10 M

Concentration of bromide ions = $[(3\times 0.1)]=0.3M$

Hence, the concentration of $Al^{3+}$ ions is 0.10 M and that of $Br^-$ ions is 0.30 M

A thermometer with a percent error of 6.5% reads the room temperature as 68°F. what is the actual temperature in the room ?

Lynna [10]

Answer:

Actual temperature for the given temperature with thermometer with error of 6.5% is 63.8 degrees.

Explanation:

The percentage error in thermometer is 6.5% this means that if the temperature is 100 degrees the thermometer shell show 106.5 degrees. now calculating the actual temperature of the thermometer when the given temperature is 68°

Applying unitary method for solution 106.5

Then 100 will be $\frac {68}{106.5} \times 100$

= $0.6384 \times 100$

= 63.8 Degrees

On solving the value of this equation will give the actual temperature as 63.8 Degrees .

Answer:

The answer to your question is: Q = 3153600 Joules

Explanation:

Data

Q = ?

m = 48 kg

T1 = 21°C

T2 = 94°C

Cp = 900 J/g°C

Formula

Q = mCpΔT

Q = (48)(900)(94 - 21) = 3153600 Joules
