Speed = distance / time = 55 / 0.75 = 73.3 miles per hour.
Answer:
If a car is moving at a <em><u>constant velocity of 10 m/s,</u></em> there will be no change in the velocity per time.
Acceleration is the rate of change of velocity
Acceleration=(Final velocity-Initial velocity)/Time
Acceleration=(10m/s-10m/s)/Time= <em><u>0 m/s²</u></em>
<h3>★ <u>0 m/s²</u> is the right answer. </h3>
35 because the water will react differntly n get warmer
Because Na⁺ ion lacks an electron and O²⁻ has two extra electrons extra, to balance the charge, we need 2 Na⁺ ions.
All ions, atoms and molecules want to get to the minimum energy state, and that state is when the ion, atom, or molecule is neutral, that's why all of them want to balance their charges.
