patriot [66]

Answer:

7.82 s

Explanation:

Given:

Δy = 300 m

v₀ = 0 m/s

a = 9.8 m/s²

Find: t

Δy = v₀ t + ½ at²

(300 m) = (0 m/s) t + ½ (9.8 m/s²) t²

t = 7.82 s

Harman [31]

Answer: D <u>(chemical</u>  -> <u>heat</u> -> <u>mechanical</u>)

In automobile engines the petrol/diesel fuel enter in to the engine cylinder, due to spark at the end of the compression, fuel burnt increase the temperature and pressure, develops heat <em>(chemical energy -> heat energy). </em><em>This heat energy acts on a piston develops the work on the crankshaft </em><em>( Heat energy -> Mechanical energy)</em><em>. </em>

What is the Kinetic Energy of a 1200 kg object that is moving with a speed of 24 m/s
SVEN [57.7K]

Kinetic Energy = 1/2mv^2

m= 1200kg

v= 24 m/s

KE = 1/2 (1200kg)(24m/s)^2 = 345,600 N

What is the mass of a sample of water that takes 2000 kJ of energy to boil into steam at 373 K? The latent heat of vaporization
GREYUIT [131]

Answer : The mass of a sample of water is, 888.89 grams

Explanation :

Latent heat of vaporization : It is defined as the amount of heat energy released or absorbed when the liquid converted to vapor at atmospheric pressure at its boiling point.

Formula used :

q=L\times m

where,

q = heat = 2000 kJ = 2\times 10^6J       (1 kJ = 1000 J)

L = latent heat of vaporization of water = 2.25\times 10^6J/kg

m = mass of sample of water = ?

Now put all the given values in the above formula, we get:

2\times 10^6J=(2.25\times 10^6J/kg)\times m

m=0.88889kg=888.89g       (1 kg = 1000 g)

Therefore, the mass of a sample of water is, 888.89 grams
