What two horizontal forces are present as a car is pushed down the driveway?(1 point)
push, velocity
power, friction
power, weight
push, friction
The two horizontal forces that are present as a car is pushed down the driveway are push and friction.
A force refers to that which produces or opposes motion. When force(s) is/are acting on a body, they either cause motion to occur or prevent motion from occurring. An example of a force which opposes motion is friction.
For a car being pushed along a driveway, the two possible horizontal forces that act on it are push which moves it forward and friction which resists its motion.

Answer:
Push and friction
Explanation:
As per Newton's third law
Every action has an equal and opposite reaction.Here the car is pushed so the force applied is pushing force
The opposition force is frictional force

A student walks a distance of 3 km in 20 minutes calculate his average speed
Answer:
His average speed is 0.15 kilometer per minute or 2.5 meters per second.
Explanation:
average speed = distance/time
x = 3 km/20 minutes
x = 0.15
—
x = 3000 m/1200 s
x = 2.5
If a student walks a distance of 3 km in 20 minutes then the average speed of the student would be 9 kilometers per hour.
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.
As given in the problem we have to calculate the average speed of the student if a student walks a distance of 3 km in 20 minutes.
The distance traveled in 20 min = 3 kilometers
The distance traveled in 60 min = 3 × 3
= 9 kilometers
Thus, If a student walks a distance of 3 km in 20 minutes then the average speed of the student would be 9 kilometers per hour.

How much work is done by a man if he moves a distance of 15m by applying the force of 20N? Find his power if he does the work in 2 seconds. (answer - 300 joule,150w)
Work= Distance × Force
15 metre × 20 N
300 Joule
Now ,
Power,
2 seconds = 300/2
150 watt
We know that
Unit of Work is Joule
Unit of Power is watt
So,
Work - 300 joule
Power= 150 watt

What do viruses and living things have in common?
Answer:
They contain genetic information needed to produce more viruses in the form of DNA or RNA.
Explanation:
Viruses are extremely small infectious agents that invade cells of all types. Once inside another cell, viruses become hijackers, using the cells' machinery to produce more viruses. Whether viruses constitute living organisms or merely conglomerations of molecules has been a source of debate for many years. One of the fundamental hallmarks of life is the ability to reproduce. Whether viruses have this ability is key to a debate over their status as living things. Some argue that since viruses cannot reproduce independently, they are not alive. However, similar to viruses, there are a few prokaryotes that are obligate parasites and cannot reproduce without a host. But these prokaryotes show another hallmark of life that viruses lack: growth. Once assembled, a virus does not change in size or chemical composition. They lack the machinery for producing energy to drive such biological processes. This makes them radically different from any known organism. Viruses do, however, show some characteristics of living things. They are made of proteins and glycoproteins like cells are. They contain genetic information needed to produce more viruses in the form of DNA or RNA. They evolve to adapt to their hosts. So while it is doubtful viruses are truly alive, they are clearly very similar to living organisms. There is more diversity among viruses than among all groups of living organisms combined. New varieties are constantly being described. It would be nearly impossible to describe all of the groups of viruses and their characteristics briefly. Instead, we will look at the characteristics shared by all viruses, such as their basic structure and general replicative cycle. Then we will discuss the features used to classify new viruses, such as shape and form of genetic material.
Answer:
cell-based life.
Explanation:
Still, viruses have some important features in common with cell-based life. For instance, they have nucleic acid genomes based on the same genetic code that's used in your cells (and the cells of all living creatures). Also, like cell-based life, viruses have genetic variation and can evolve

Answer :Glaciers cause erosion by abrasion and
plucking
. The sediment deposited by glaciers is called till.
When a chunk of ice left behind by a receding glacier melts, the water stays in the kettle, forming a kettle lake.
Explanation:
I took the test
A) Glacier causes erosion by abrasion and plucking.
B) The sediment deposited by glaciers is called a moraine.
C) When a chunk of ice remained behind by a receding glacier melts, the water stays in the kettle, forming a kettle lake.
What are abrasion, plucking, and moraine?Abrasion contains the wear, polishing, and scratching produced in the bedrock by the thicker rock fragments brought by the ice, and in that way, grooves are formed.
Plucking generally takes place when advancing ice will push against fractured bedrock. Additional breaks can produce stress, while warmer temperatures and friction from glacier movement can bring the melting.
Moraine is the deposit of trawls of material fragmented by glaciers, which create mountain ranges because of their accumulation.
Glaciers are contacted by ice deposits due to continental glaciation. These forms develop with the glacier outwash and leave ice deposits. It generates a kettle lake when a large chunk of ice left a depression in the glacial drift when the ice melts a kettle-like hole is formed.

A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes.Explanation:

Explain the Kinetic Theory of Matter
and use an example from everyday life
Answer:
The Kinetic Theory of Matter or KTM as i will call it, states that every object is made of many many small particles (humans are made of sextillions of atoms), and that they are constantly moving and bumping each other. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
An example would be Brownian Motion- the random movement of dust particles because of collisions with "air" molecules and how gases behave i.e. Boyle's, Charles', and Gay-Lussac's Laws.
