The answer would be erin out of all of them thank me later :)
Hi there!
Acceleration = change in velocity / change in time = Δv/Δt
Thus:
a = (75 - 15)/4 = 60/4 = 15 mi/hr²
Answer: Copper and oxygen
Explanation:
Copper and oxygen shares the ionic bond. As we know that ionic bond is the most strongest bond. Here is the order:
Hydrogen bond< Metallic bond< Ionic bond.
That means order in terms of increasing bond strength is :
Hydrogen and hydrogen< Copper and copper< Copper and oxygen.
<span>The 23.5 degree tilt is responsible for the seasons. If the earth had no tilt there would not be seasons. If the earth was tilted by 90 degrees the seasonal changes would be at the most extreme. The Earth's pole would point directly at the sun at a point on the track around the sun. As the Earth revolves around the Sun the pole would alternate twice each year between pointing directly at the sun and being perpendicular to the sun.
I hope this helps you!
