Answer:
A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.

Answer:
The initial temperature of the water is -75.08 K.
Explanation:
Given that,
Mass of water, m = 27 g
Heat absorbed, Q = 1,5000 J
Final temperature of water, T₂ = 57.7 K
The specific heat of water is 4.184 J/g-K
We know that,
Put all the values,
So, the initial temperature of the water is -75.08 K.
I believe the correct answer from the choices listed above is option A. The E+ of the cell would be 2.47 V. E of the cell is given by the formula E(cathode) - E(anode) . <span>So in this case the first half cell reaction is the reaction that takes place in the cathode and the second one takes place in the anode.</span>
