C) Organ system.
Your organs are working together to control and keep your body moving!! When a organ starts to do they're job it may need some other organs to help. When this happens it begins the Organ System!
200 ms² is the kinetic energy for an object that weighs 40g and moving at 10 m/s.
<h3>What are kinetic energy ?</h3>
Kinetic energy is the power that an object has had as a result of motion. To accelerate an object, a power must be supplied to it. To apply a force, we must exert effort. The power is transported to the object when work is accomplished, which causes it to move at a new, constant pace.
<h3>What makes kinetic energy so important?</h3>
The capacity to perform work is unquestionably the most important characteristic of kinetic energy. Force acting on to an object while it is traveling is referred to as work. Energy and work are interchangeable because of their close relationship.
<h3>Briefing:</h3>
Using Kinetic Energy Formula:
K.E = 1/2 mv²
K.E. = 1/2 * 40 * 10
K.E. = 200 ms²

Answer: a stone thrown into a lake
Explanation:
The option that exhibits parabolic motion is a stone that is thrown into a lake.
Projectile motion is a form of motion that is seen when a particular object is thrown towards the surface fo the Earth. Such objects are acted upon by gravity.
Answer: Work done = 153.125Joules, Work done = 0.003Nm
Explanation:
Kinetic energy of a body is the energy possessed by a body by virtue of its motion.
Mathematically,
K.E = 1/2MV²
Where;
M = mass of the body = 2.5g = 0.0025kg
V = velocity of the body = 350m/s
Substituting this values in the formula, we have;
K.E = 1/2× 0.0025×350²
K.E = 153.125Joules
Work done is the force applied to body to cause it to move through a distance.
Work = Force × distance
Force = ma = 0.0025 × 10
Force = 0.025N
Distance = 12cm = 0.12m
Work = 0.025×0.12
Work = 0.003Nm
work done by the tree in stopping the bullet is 0.003N
Answer:
Voltage, V = 0.0741 volts
Explanation:
It is given that,
Width of membrane,
Electric field strength,
We need to find the voltage across membrane. Electric field is given by :
V = 0.0741 V
So, the voltage across the membrane is 0.0741 volts. Hence, this is the required solution.
