Answer:

Freezing Point - Lower

Boiling Point - Higher

Solid- liquid transition line in the phase diagram has a negative slope, but the liquid-gas transition line has a positive slope. Since there is more air pressure at 100m it will take less to freeze the water but more to boil it since it requires a larger temperature under larger pressures

Resistance is equal to relation between voltage and current.

$R = \frac{U}{I}$

If we express current:

$I = \frac{U}{R}$

If current is in fact 0 then one of the quantities either voltage or resistance must be equal to zero. Since resistance cannot be equal 0, because that would violate mathematical law that states that division by zero is undefined the only logical conclusion is voltage.

So the answer should be C voltage and B zero.

Hope this helps!

Answer:

23.02 h.

Explanation:

Power is defined as the time rate at which energy is dissipated.

Mathematically,

Power = Energy/time

Energy = I * V * t

Where,

I * t = current

= 61 Ah

V = potential difference

= 12 V

Power = 31.8 W

Therefore,

31.8 = (61 * 12)/t

t = 732/31.8

= 23.02 h

Converting to seconds,

= 23.02 h * 3600 s/1 h

= 82867.9 s.

defon

Answer:

43850.49112 kg

Explanation:

M = Mass of moon = $7.36\times 10^{22}\ kg$

r = Distance from Moon's center = $5.23\times 10^6\ m$

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

m = Mass of black hole

F = Force = 7870 N

From the universal force of gravity we have

$F=\frac{GMm}{r^2}\\\Rightarrow m=\frac{Fr^2}{GM}\\\Rightarrow m=\frac{7870\times (5.23\times 10^6)^2}{6.67\times 10^{-11}\times 7.36\times 10^{22}}\\\Rightarrow m=43850.49112\ kg$

The mass of the mini black hole is 43850.49112 kg
