Answer:
Explanation:
As we know that initial speed of the fall of the stone is ZERO
also the acceleration due to gravity on Mars is g
so we have
now we have
now if the same is dropped for 4t seconds of time
then again we will use above equation
Acceleration = (change in speed) / (time for the change)
Acceleration = (4 m/s) / (8 seconds)
Acceleration = 0.5 m/s²
Force = (mass) x (acceleration)
Force = (85 kg) x (0.5 m/s²)
Force = 42.5 Newtons
Answer:
<em><u>energy</u></em>
Explanation:
The heating and cooling of molecule will make <em><u>energy</u></em> change their state of matter.
Answer:
Atoms form chemical bonds to satisfy the Octet rule and become Stable element.
Explanation:
- Every atom desires to achieve total eight valence electron in their outermost shell to become stable. This rule is known as octet rule.
- During the chemical reaction process, every element goes through the process of receiving or donating the element to complete the octet rule to become stable.
- The electronic configuration of element having eight electrons in its valence shell is the noble gases.
I believe the answer is convection!
