Using your best estimates, how many times would you have to slap a 1 kg rotisserie chicken in order to cook it? You can assume t

FromTheMoon [43]

Answer:

n= 16021.03 slaps

Explanation:

Using law of Energy conservation

E_{thermal}= Kinetic energy of hand

⇒ $mc\Delta T= n\frac{1}{2}m_hv_h^2$

m_h= mass of the hand = 0.4 kg

v_h= velocity of the hand = 10 m/s

n= number of slaps

c= 4180 J/Kg °C

m= mass of chicken = 1 kg

Assuming all the energy of hand goes into chicken

Given Ti=0°C and T_f= 170 F= 76.66°C

Now putting the values in above equation to get n

$1\times4180(76.66)= n\frac{1}{2}0.4\times10^2$

n= 16021.03 slaps

A series RCL circuit is at resonance and contains a variable resistor that is set to 206Ω. The power dissipated in the circuit i

mash [69]

Answer:

Power dissipated in resistor 532 ohm is 0.503 watt

Explanation:

We have given in first case resistance $R_1=206ohm$

Power dissipated in this resistance is $P_1=1.30watt$

Power dissipated in the resistor is equal to $P=\frac{v_{rms}}^2{R}$

We have to find the power dissipated in the resistor is 1.30 watt

From the relation we can say that $\frac{P_1}{P_2}=\frac{R_2}{R_1}$

$\frac{1.3}{P_2}=\frac{532}{206}$

$P_2=0.503watt$

So power dissipated in resistor 532 ohm is 0.503 watt

yKpoI14uk [10]

Answer:

1) Buoyant force, 2) sinks, 3) equilibrium, 4) fleet , 5) LIFT force

Explanation:

A body in a fluid is subjected to two forces, its weight and the thrust

sun F = B - W

the em

bid is always vertical and contrary to weight, let's analyze and complete the different situations presented

1) Buoyant force

2) sinks B <W

3) equilibrium B = W

4) fleet B> W

5) by the sum of two forces:

* Thrust, but the density of air is much less than the density of water, therefore the thrust in the air is less.

* The other force in airplanes the lift force given by the difference in the path of the air when the plane moves, which translates into a pressure difference between the upper part of the wing and the lower part, it is force is called LIFT force
