Answer:

5010J

Explanation:

Work is force times distance, or

W=F⋅d.

Substitute in values from the question to get

W=8.35⋅102N⋅6m=50.1⋅102Nm=5010J

Answer:

Explanation:

C = (F-32)*5/9 = 73*5/9 = 40.55555

since the answers are spread apart, technically you can just estimate by doing -32

and then /2

since 5/9 is close to 1/2

Ocean waves are hitting a beach with a frequency of 0.100 Hz. Their average wavelength is 15.0 m. What is their average speed?

den301095 [7]

Answer:

Average speed=1.5 m/s

Frequency of pendulum=93.75Hz

Explanation:

We are given

Frequency, $f=0.100Hz$

Average wavelength = $\lambda=15m$

Speed of pendulum, $v=30m/s$

Wavelength, $\lambda'=0.32m$

We have to find the average speed and frequency of pendulum.

We know that

Speed, $v=\lambda f$

Using the formula

Average speed, $v=15\times 0.1=1.5m/s$

Hence, the average speed =1.5m/s

Frequency, $f=\frac{v}{\lambda'}$

Using the formula

$f=\frac{30}{0.32}$

$f=93.75Hz$

Hence, the frequency of a pendulum=93.75Hz

A 230.-mL sample of a 0.240 M solution is left on a hot plate overnight; the following morning, the solution is 1.75 M. What vol

Gwar [14]

Answer:

The volume of water evaporated is 199mL

Explanation:

Concentration is calculated with the following formula

$C=\frac{n}{V}$

where n is the number of moles of solute and V is the volume of the solution (in this case is the same as the solvent volume) in liters.

So we isolate the variable n to know the amount of moles, using the volume given in liters

$230mL=0.23L$

$n=C*V=0.240 M*0.23L=0.055 mol$

Now, we isolate the variable V to know the new volume with the new concentration given.

$V=\frac{n}{C} =0.055mol/1.75M=0.031L=31mL$

Finally, the volume of water evaporated is the difference between initial and final volume.

$V_{ev}= V_{i} -V_{f} =230mL-31mL=199mL$
