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.

Which describes an INHERITED TRAIT of a plant?
The broken branch of a tree
The torn flower petal
The green color of a leaf
The holes in a leaf caused by an insect-eating it.
Answer: the green color of a leaf
Explanation: because the other things are physical changes of a plant that don't get passes down to offspring
Answer:
The green color of the leaf
Explanation:
That is a trait they have by birth and is what they had passed on to them.
In Hans Oersted’s experiment, why did a compass needle move when an electric current flowed through a nearby wire?
A. The compass conducted electricity.
B. The current created a magnetic field around the wire.
C. The compass was broken.
D. The current changed Earth’s magnetic field.
Answer:
B. The current created a magnetic field around the wire
Explanation:
Hans Oersted discovered the magnetic effect of the electric current. In his experiment, he discovered that when the electric current flowed through a wire a magnetic field was created and the wire acted as a magnet.

Answer:A
Explanation:
What are INHERITED TRAITS?
The offspring of a plant
Characteristics are passed down from the offspring to the parent.
The parent of an offspring
Characteristics passed down from parent to offspring.
Answer:
Characteristics passed down from parent to offspring.
Explanation:
Inherited traits are given to the offspring from the parents.
"Characteristics are passed down from the offspring to the parent" does not make sense.
"The offspring of a plant" and "The parent of an offspring" are wrong.
Answer:
Characteristics are passed down from parent to offspring
Explanation:
This is because that inherited means that you are given them, these traits are given to you from your parents

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.
Answer:
I think you answered that yourself
Explanation:
Which of these conclusions is most likely correct about the location from where the fossil was discovered?
It was a sea which was replaced by a forest.
It was a forest which was replaced by a sea.
It is mainly covered with salt water bodies.
It is mainly covered with fresh water bodies.
Answer:
A.
Explanation:
Millions of years ago, most of the foests we see today used to be oceans. In modern-day we find fossils in the ground from those old eras long ago, back when there were only sea creatures on earth and we find these.
