What displacement do I have if I travel at 10 m/s E for 10 s? <br> I need this fast
lapo4ka [179]

Answer:

100m.

Explanation:

Simply put, displacement is how far you've been displaced from your starting location. say you start at 0. You now travel E (assuming East) at 10 m/s for 10 s. Now, let's assume m is meters and s is seconds. you moved east at 10 meters per second for 10 seconds. This means that for each second you moved east, you moved 10 meters. Therefore, your displacement is 100 meters because 10 times 10 is 100. So you would write 100m as your displacement.

Ammonia at 10◦c with a mass of 10 kg is in a piston/cylinder assembly with an initial volume of 1 m3. the piston initially resti
jeyben [28]

Here mass is floating on the piston at equilibrium

So it will have constant pressure always remains constant

So final pressure is same as initial pressure = 900 kPa

now we can say

\frac{V_1}{V_2} = \frac{T_1}{T_2}

\frac{1}{V_2} = \frac{273+10}{273+50}

V_2 = 1.14 m^3

so final pressure is 900 kPa and final volume is 1.14 m^3

The diagram below shows eight different positions of the moon around Earth.
KATRIN_1 [288]

Answer:

6 and 8

Explanation:

The different positions of the moon, as seen from Earth, reflect how much light is being reflected off the moon from the sun.

Position 1 indicates the 3rd Quarter.

Position 2 indicates the Waning Gibbous.

Position 3 indicates the Full Moon.

Position 4 indicates the Waxing Gibbous.

Position 5 indicates the 1st Quarter.

Position 6 indicates the Waxing Crescent.

Position 7 indicates the New Moon.

Position 8 indicates the Waning Crescent.

You would read the diagram counterclockwise, with positions 7 to 3 as the moon increases light and positions 3 to 7 as the moon decreases light.

Therefore, we see that our 2 choices where we have a crescent is positions 6 and 8.
