A parked car begins to roll down a hill, what can you conclude from that observation?
A force was required to start the car rolling.
The rolling friction is equal to the car’s weight.
The rolling friction is greater than the force of the car’s weight against the hill.
The car will stop when a force equal to the weight of the car is applied against the car.

What are biomes?Biomes can be defined as regions specified by particular biological and geographical communities that evolved because of the shared regional climate of that region.
In the natural world, symbiotic partnerships can take one of three main forms: parasitism, commensalism, or mutualism. Mutual benefit: both parties win.
There are certain populations that work together. The right response is option C since this is a situation in which individuals of the same species collaborate in order to survive.

What is the correct term for the flow of charged particles?
A. electricity
B. electric force
C. electric force
D. electric chargeelectric charge
Answer:
I would say electric current, but since that isnt a given choice, i would choose electricity.
Explanation:
an electric force is an attraction between two charged particles, not the flow.
electric charge is the cause of the electric force.
again im not sure, hope this helps!
The correct term for the flow of charged particles is known as electric current or electricity. Hence, option A is correct.
What is Electrical energy?Charged material experiences a force when exposed to an electromagnetic field because of the fundamental characteristic of electric charge. It's conceivable for electrical ions to be positive or negative. Two charges that are opposed to one another repel one another.
An object with no net charge is said to be "neutral." Classical electrodynamics refers to the older theory of how charged particles interact, and it is still valid for problems that do not necessitate accounting for quantum phenomena.
The net charge of an isolated system, which is the total of the negative and positive charges, cannot change since electrical current is a conserved property. Electric charge is carried by subatomic particles.
Therefore, it concludes that flow of charged particles is termed as electricity.

The unicorn suddenly ran through the school at 5.6 m/s and it has a mass of 450 kg. What is the unicorn’s kinetic energy?
Answer:
KE = 567000 J
planation:
The kinetic energy of the unicorn can be find out from its mass and velocity. The kinetic energy of unicorn is 7056 J.
What is kinetic energy ?Kinetic energy is a form of energy on an object generated by virtue of its motion. It is related to the mass and velocity of the object by the expression written below:
Ke = 1/2 m v²
When an object starts moving from rest, its potential energy converts to kinetic energy. As the mass and velocity increases, kinetic energy increases.
Given that, m = 450 kg
v = 5.6 m/s
then , Ke = 1/2 450 kg × (5.6 m/s )² = 7056 J.
Therefore, the kinetic energy of the unicorn is 7056 J.

How does the velocity of a moving object depend on the choice of frame of reference?
Imagine you threw and caught a ball while you were on a train moving at a constant velocity past a station. To you, the ball appears to simply travel vertically up and then down under the influence of gravity. However, to an observer stood on the station platform the ball would appear to travel in a parabola, with a constant horizontal component of velocity equal to the velocity of the train. This is illustrated in Figure 1 below.
(Path of the ball as seen by an observer on the train and an observer at the station.)
The different observations occur because the two observers are in different frames of reference. A frame of reference is a set of coordinates that can be used to determine positions and velocities of objects in that frame; different frames of reference move relative to one another.
The laws of physics are the same in all inertial frames (this is known as Galilean invariance). Put in another way, there is no experiment that you could do to determine which reference frame you are in (Einstein used this hypothesis to devise the theory of Special Relativity). This means that we can address problems in any reference frame to give an equivalent solution.
