Answer:  My hypothesis is that the water was going to melt at 25-degrees Celsius and boil at 100-degrees Celsius. It turns out that my hypothesis was almost correct, the ice actually melted a little sooner. It melted at 20-degrees Celsius. So my hypothesis was incorrect.

This is the answer i got.


  My hypothesis is that the water was going to melt at 25-degrees Celsius and boil at 100-degrees Celsius. It turns out that my hypothesis was almost correct, the ice actually melted a little sooner. It melted at 20-degrees Celsius. So my hypothesis was incorrect.

Latent heat is changing phase, and when a change in phase is accomplished at constant pressure temperature is constant. On the phase diagram, latent heat shows up as a "thermal plateau" where the graph is a flat line for a brief portion. The melting point of the ice was about 20-25 degrees celsius when it started turning into water, and at 100 degrees celsius when it started boiling. I could tell because the ice turned into water and the water got very hot.

The practical applications for this procedure were, ice,a pot,and a stove.

A big wheel at a theme park has a diameter of 14m and people on the ride complete one revolution in 24s. calculate the distance
just olya [345]

Explanation:

We'll call the radius r and the diameter d:

We also assume that the riders are at a distance r = d/2 = 7m from the center of the wheel.

The period of the wheel is 24s. The tangent velocity of the wheel (and the riders) will be: (2pi/T)*r = 0.8 m/s (circa).

It means that in 3 minutes (180 seconds) they'll run 0.8 m/s * 180s = 144m.

Hopefully I understood the question. If yes, that's the answer.

Answer:

Range = 22.61 m

Explanation:

We can use the formula for the Range in flat ground, given by:

Range=v_i^2\frac{sin(2\theta)}{g}

which for our case renders:

Range=15^2\frac{sin(80^o)}{9.8} \approx 22.61\,\,m
