As we know that the conductance is given by the formula
now here we know that
L = length
now we know that conductance will remain constant while the length is quadrupled
so here we have
so here radius becomes double
so correct answer will be
<em></em>
Answer: the horizontal component of total momentum
Explanation:
Since the open cart is rolling to the left on the horizontal surface, the quantity that has the same value just before and just after the package lands in the cart is the horizontal component of total momentum.
Momentum, is the product of the mass of a particle and the velocity of the particle. The change of momentum depends on the force which acts on it. The addition of the the individual momenta is the total momentum.
Answer:
(a) The rate of heat transfer is <em>238.26 kW.</em>
(b) Rate of entropy generation is <em>0.063 kW/K.</em>
Explanation:
(a) Taking the heat gained by the cold water into consideration,
<em></em>
<em>Q = (0.95 kg/s)(4.18 kJ/kg.⁰C)(70-10) = 238.26 kW.</em>
(b) Entropy generation = entropy in cold water + entropy in hot water
But
∴ = (0.95)(4.18)(ln(343/283)) + (1.6)(4.19)(ln(1- (238.26/((1.6)(4.19)(358))))
= 0.7636 + (- 0.7009) = 0.0627 kW/K.
The answer is transformed
because you changed the kind of energy
OK think of it distance,The smaller the distance less momentum is needed the Longer the distance the the longer the momentum is needed.
And The Answer Is quite easy their was no reason to be asked
Answer:1.0meter
