Answer:
s = 2.16 x 10¹¹ m
Explanation:
Since, the waves travelling from Earth to the Mars rover are electromagnetic. Therefore, there speed must be equal to the speed of light. So, from the equation given below:
s = vt
where,
s = the distance between Earth and Mars = ?
v = speed of the wave = speed of light = 3 x 10⁸ m/s
t = time taken by the radio signals to reach the rover from Earth
t = (12 min)(60 s/1 min) = 720 s
Therefore,
s = (3 x 10⁸ m/s)(720 s)
<u>s = 2.16 x 10¹¹ m</u>
Answer:
electrons are completely transferred from one atom to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form ions. The oppositely charged ions are attracted to each other by electrostatic forces, which are the basis of the ionic bond.
Explanation:
The reason why it relates to the newtons 3 laws of motion because the first law of motion states that every object will stay at rest unless it's moved by an unbalanced force which is your hand. The second one states that <span> the velocity of an object changes when it is subjected to an external force meaning it's used by the equation that is commonly used for which is F=M*A. The way it relates to the second law because you are adding force some way or another, the mass is the egg and the acceleration is the drop of the egg while it free falls. And the last one, for a reaction there is always an equal or opposite reaction and the opposite reaction is the floor because it's going against the egg causing it to crack. If it was with the egg, it would have a soft, smooth landing.</span>
