When g=a, that means everything on earth fall at the same rate.
<h3>Why does everything fall to the earth at the same rate?</h3>
As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.
<h3>Why is gravity equal to acceleration?</h3>
When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.

Answer:
Chemical energy
Explanation:
The energy held in the foods molecules a lunch pack is composed of is chemical energy.
They occur within food substances which originates from plants and animals as giant organic molecules.
- Since food is often derived from plants and animals.
- Plants produce their own food by producing macromolecules from simple inorganic substances in the environment.
- Animals takes up these food and build their own body through it.
- Plants and animal parts constitutes organic molecules in which chemical energy is duly stored.
- When the molecules are broken down, they released their chemical potential energy into heat energy.
Answer:
Explanation:
Given:
Mass of the boat, m = 4040 kg
The driving force of engine, FB = 4660 N in west = + 4660 N
The force of wind, Fwi = 880 N in east = -880 N
The force of water, Fwa = 1400 N in east = -1400N
Total three forces are acting on the boat
Fnet= Fb+fwi+Fwa
Fnet= 4660 - 880 - 1400
Fnet= +2380N
Acceleration (a) = Force/mass
= 2380/4040
= 0.59m/s2
Answer:
the correct answer is C. an unbalanced force
Explanation:
All the other choices just don't make any sense.
