Ghee freezes from bottom but water freezes from top, why?

1 answer:

8 0

I presume you mean ghee as in the butter. Seen as ice is one of the many solids to have a lower density than its liquid form, it freezes from the top. Ghee is made from hydrocarbons not dissimilar to petroleum, it shares the same properties as most elements of its solid state (at 1 atmosphere) being at a higher density than its liquid state.

A projectile is fired straight upward at 173 m/s. how fast is it moving at the instant it reaches the top of its trajectory?

Fittoniya [83]

The top of the trajectory is the point where it changes from rising to falling. At that exact instant, its vertical speed is zero.

A proton is released from rest at the positive plate of a parallelplatecapacitor. It crosses the capacitor and reaches the negat

Triss [41]

Answer:

2.1406 × $10^6$ m/sec

Explanation:

we know that energy is always conserved

so from the law of energy conservation

$qV=\frac{1}{2}mv^2$

here V is the potential difference

we know that mass of proton = 1.67× $10^{-27}$ kg

we have given speed =50000m/sec

so potential difference $V=\frac{\frac{1}{2}\times 1.67\times 10^{-27}50000^2}{1.6\times 10^{-19}}=13.045$

now mass of electron =9.11× $10^{-31}$

so for electron

$\frac{1}{2}\times 9.11\times 10^{-31}v^2=1.6\times 10^{-19}\times 13.045=2.1406\times 10^6 m/sec$

so the velocity of electron will be 2.1406× $10^6$ m/sec

How many miles can you get on one tank of gas if your tank holds 18 gallons and you get 22 miles per

MrRissso [65]

Multiply the two. The units will cancel out. 22 miles per gallon can be expressed as 22 miles / 1 gallon, so you can write the following:
18 gallons * 22 miles / 1 gallon
Which simplifies to 18 * 22 miles = 396 miles.
