While working out, a man performed 375 J of work in 11 seconds. What was his power?

2 answers:

8 0

Power is determined by work/time.
We have P = W/T as our formula.
There is 375J of work, and 11s of time.
Plug in 375J for Work, and 11s for Time.
P = 375/11
Our power is 34.09.
Hope this helps!

It is made<span> by freezing flavored liquid (such as fruit juice) around a stick, generally resembling a tongue depressor. Often, the juice is colored artificially. Once the liquid freezes solid, the stick can be used as a handle to hold the ice pop</span>

After the box comes to rest at position x₁, a person starts pushing the box, giving it a speed v₁. When the box reaches position

Vesna [10]

Answer:

$W_p = \frac{1}{2}mv_1^2$

Explanation:

As we know that box is initially at rest

So we will have

$v_i = 0$

now as it will be displaced from initial position to final position then final speed of the box is reached to

$v_f = v_1$

now we know by work energy theorem that work done by all the forces on the box will be equal to the change in kinetic energy

So here we will have

$W_p = \frac{1}{2}m(v_f^2 - v_i^2)$

$W_p = \frac{1}{2}m(v_1^2 - 0)$

$W_p = \frac{1}{2}mv_1^2$

What will happen to a waves frequency if it’s speed increases and it’s wavelength remains the same?

VLD [36.1K]

Answer:Actually the wavelength is proportional to its speed and frequency. therefore the wavelength has no affect on the speed or frequency its the other way around.

If a 0.750M solution exerts an osmotic pressure of 22.5atm, what must be the temperature (in Kelvin) of the solution

faust18 [17]

Answer:

T = 365.58 K

Explanation:

Given that,

The concentration of solution, C = 0.750M

Osmotic pressure, P = 22.5 atm

We need to find the temperature of the solution.

The formula for the osmotic pressure is given by :

$P=CRT$

Where

R is gas constant, $R=0.08206\ L\ atm/mol-K$

$T=\dfrac{P}{CR}\\\\=\dfrac{22.5}{0.75\times 0.08206}\\\\=365.58\ K$

So, the temperature of the solution is 365.58 K.
