Graph D; They have the same slope, but start at a different distance.
Answer:
A) 4037.2[km]; B) 21472[m/s]
Explanation:
A)
This part can be solved using the principle of energy conservation, where kinetic energy will be equal to potential energy. We will define the kinetic energy and the potential energy.
![Ek= 0.5*m*v^2\\where:\\m = mass [kg]\\v = 8.90*10^3[m/s]\\Ep=m*g*h\\where:\\g = gravity = 9.81[m/s^2]\\h = elevation or height [m]\\](https://tex.z-dn.net/?f=Ek%3D%200.5%2Am%2Av%5E2%5C%5Cwhere%3A%5C%5Cm%20%3D%20mass%20%5Bkg%5D%5C%5Cv%20%3D%208.90%2A10%5E3%5Bm%2Fs%5D%5C%5CEp%3Dm%2Ag%2Ah%5C%5Cwhere%3A%5C%5Cg%20%3D%20gravity%20%3D%209.81%5Bm%2Fs%5E2%5D%5C%5Ch%20%3D%20elevation%20or%20height%20%5Bm%5D%5C%5C)
Now we have to match both equations in this way the mass value is canceled and we can clear h.
![0.5*m*(8.9*10^3)^{2}=m*9.81*h\\ h=4037206.93[m] = 4037.2[km]](https://tex.z-dn.net/?f=0.5%2Am%2A%288.9%2A10%5E3%29%5E%7B2%7D%3Dm%2A9.81%2Ah%5C%5C%20h%3D4037206.93%5Bm%5D%20%3D%204037.2%5Bkm%5D)
B)
To solve this problem we can use the kinematic equations, but first we must identify the initial data:
yo = 2.35*10^7[m]
y = 0 [m] when hit the ground [m]
vo = 0 [m/s], It is essentially at rest...
![v_{f} ^{2} =v_{o} ^{2} +2*a*(y)\\v_{f} =\sqrt{2*9.81*2.35*10^{7} } \\v_{f} =21472.54[m/s] o 21.47[km/s]](https://tex.z-dn.net/?f=v_%7Bf%7D%20%5E%7B2%7D%20%3Dv_%7Bo%7D%20%5E%7B2%7D%20%2B2%2Aa%2A%28y%29%5C%5Cv_%7Bf%7D%20%3D%5Csqrt%7B2%2A9.81%2A2.35%2A10%5E%7B7%7D%20%7D%20%5C%5Cv_%7Bf%7D%20%3D21472.54%5Bm%2Fs%5D%20o%2021.47%5Bkm%2Fs%5D)
The magnitude of the force each hook exerts on the chain is 22.2N.
<h3>Solution:</h3>
Horizontal force on one half of the chain
cos 42° = 
sin 42° = 20
= 29.9N
Now,
= 22.2N

Answer:
the lawyer should Inform Mr. X through that Tax attorney and ABC management to get approval.
Explanation:
According to my research on different lawyer proceedings, I can say that based on the information provided within the question before taking Paula's Case the lawyer should Inform Mr. X through that Tax attorney and ABC management to get approval. This can be said because since both Mr.X and Paula are clients of the law firm, there may be a breach in confidentiality if the lawyer decides to take Paula's case. Therefore he needs to talk to everyone involved and place restrictions if the case is taken.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
Answer:
The Old Thermodynamist says:
Recall ΔH = m•Cp•ΔT where H is enthalpy (heat), m is mass Cp is heat capacity and ΔT is temperature change.
The heat capacity of water is dependent on temperature, but is commonly taken as 4.186kJ/kg-K
In this case, we have 8kg of water and a temperature change ΔT = 80K
So ΔH = 8(4.186)(80) = 2679.0kJ
The heat required is 2679.0kJ (which is 0.744kWh
