How much heat Q2Q2 is transferred to the skin by 25.0 gg of steam onto the skin? The heat of vaporization for steam is L=2.256×1
astraxan [27]

Answer:

56400Joules

Explanation:

The quantity of heat required is expressed as;

Q = mL

m is the mass = 25g = 0.025kg

L is the latent heat of vaporization for steam = 2.256×10^6J/kg

Substitute into the formula as shown;

Q = 0.025×2.256×10^6

Q = 56400Joules

Hence the quantity of hear required is 56400Joules

The density of water is 10*3 kg/m*3. the water pressure on a submarine is 2.0 x 10*7 N/m*2. The depth of the submarine below the
Marat540 [252]

Answer:

2000metres

Explanation:

Pressure= density x height x gravity

Gravity is always a constant = 10N/kg

so height= Pressure/( density x gravity)

h= 20000000/(1000 x10)

h= 2000 metres

A bullet was fired from a gun. The bullet had a mass of 50g and the kinetic energy of the bullet was 25 kJ. How fast did it go?
Elenna [48]

Answer:

given \:  \\ mass \: (m) = 50g \\ kinetic \: enegy \: (k.e) = 25kj \\ velocity(v) = x \\ form \\ k.e =  \frac{1}{2}  \times MV ^{2}  \\ 25 =  \frac{1}{2}  \times 50 \times v {}^{2}  \\ 25 = 25 \times v {}^{2} \\ v {}^{2}  =  \frac{25}{25}  \\ v {}^{2}  = 1 \\ v =  \sqrt{1}  \\ v = 1ms {}^{ - }

the car it go fast with velocity 1m/s
