Answer:

A, B, And C,

Explanation:

The law of conservation of energy is a physical law that states energy cannot be created or destroyed but may be changed from one form to another. Another way of stating this law of chemistry is to say the total energy of an isolated system remains constant or is conserved within a given frame of reference.

Which changes in surface water movement are likely
to occur when vegetation is removed from the side of
a hill?
A) infiltration decreases and runoff decreases
B) infiltration decreases and runoff increases
C) infiltration increases and runoff decreases
D) infiltration increases and runoff increases

Answers

Answer:

infiltration decreases and runoff increase

Explanation:

The changes in surface water movement which is likely to occur when vegetation is removed from the side of a hill is infiltration decreases and runoff increases.

What is surface overflow?

Surface overflow is the flow of water which take place on the surface of the ground. The extra water due to rain or flood arises on the ground or at the surface, flows in the nearby lacks or ponds.

Now if the vegetation is removed, great amount of water started to come from the hills. The result of it, more water started to overflow on the land of the surface. This way the runoff increases.

Infiltration is the way by which the ground level water enters into the soil of the earth.

Now, if the vegetation is removed, a lot of amounts of water started to come from the hills. This excess amount of water does not enter in to the soil of the earth.

The changes in surface water movement which is likely to occur when vegetation is removed from the side of a hill is infiltration decreases and runoff increases.

What is a projectile?

A projectile can be defined as an object upon which experiences only force is gravity. The projectile covers the path with a parabolic trajectory because of the effect of gravity. No horizontal forces act upon projectiles which causes no horizontal acceleration.

The velocity of a projectile is divided into two components one is the horizontal component and the other is the vertical component.

If the projectile makes an angle θ with the X- axis.

The vertical component of the velocity, Vy = Vsinθ

The horizontal component of the velocity, Vx = Vcosθ

Given the angle θ with the X- axis = 57°

The velocity of the projectile V = 35 m/s

Then the vertical or Y component of the velocity, Vy = Vsinθ =

Y component = 35× sin 57°

Vy = 29.35 m/s

The small piston of a hydraulic lift has an area of 0.20 m2. A car weighing 1200 N sits on a rack mounted on the large piston. The large piston has an area of 0.90 m2. What is the mechanical advantage of the hydraulic lift?

Answers

Answer:

4.5

Explanation:

Given the following

Weight of the car = 1200N (Load)

Let us get the effort by using the formula;

F1/A1 = F2/A2

Substitute the given values

1200/0.9 = F2/0.2

Cross multiply

0.9F2 = 1200 * 0.2

0.9F2 = 240

F2 = 240/0.9

F2 = 266.67N

Hence the effort is 266.67N

Mechanical Advntage = Load/Effort

MA = 1200/266.67

MA = 4.5

Hence he mechanical advantage of the hydraulic lift is 4.5

Mental health disorders may NOT affect...
O
A person's motivation levels
O
The ability to make decisions
о
A person's memory or ability to make new memories
A person's ability to breathe

Answers

In my opinion, mental health can affect all of these options. However, I think the answer this is looking for would be "A person's ability to breathe"

Mental health definitely affects motivation; and motivation affects mental health. Motivation is a driving force behind human behaviours; its absence can lead to mental illnesses such as depression. Often when someone is depressed, they lack the motivation to do things.

Mental health can affect decision making as well- for example, if someone has anxiety, decision-making can be harder. Anxiety disrupts the decision-making regions in the prefrontal cortex.

Mental health can also affect memory- Depression has been linked to memory problems, such as forgetfulness. Depression is associated with short-term memory loss. Stress and anxiety can also lead to poor memory.

I would say that panic attacks can inhibit a person from breathing, but considering the options I would say that's the best one. Breathing is more of a physical thing, not associated with the brain or mental condition. So the answer is A person's ability to breathe.

After rubbing a rubber brush on wool, Gilbert is able to use the brush to pick up small strips of paper. What causes the paper to be attracted to the brush?
A.) gravity
B.)electric current
C.) static electricity
D.)magnetism

Answers

Static electricity because when you rub something against a surface, there is friction aka static electricity.

After rubbing the a rubber brush on the wool it gets a charge acquired by the passage of electrons. The electrons from the wools escapes to the brush and thus the paper get attracted to electrons in the brush. Hence, option B is correct.

What is electric current?

Electric current is the passage of electrons from the negative end to positive end of a  potential difference.

When a an object is rubbed on a conducting material it gets some electrons into it.  When this material comes in contact with another object which have random distribution of charges will attracts the electrons by its positive end.

The rubber brush gets negatively charged on rubbing.  Paper have positive and negative charges in random. When it comes in contact with the negatively charged brush the electrons in the paper repelled away.

The positive charges thus accumulates on the other end of the paper and attracted to the brush. This is an example of static current. Hence option B is correct.

What is a linear relationship?

A linear relationship is a type of association between two variables where a change in one produces a direct modification in the another one.

A linear relationship may change depending on the rate of change and therefore the size of this variation is not the same.

What is electromagnetic induction?

When a magnetic field is in motion with respect to a conductor, such as a wire, it induces an electric current in the wire. This is because the changing magnetic field creates a changing electric field around the wire, which causes electrons to flow. The induced electric current is proportional to the rate of change of the magnetic field. This consequence is known as electromagnetic induction.

The strength of the magnetic field does affect the magnitude of the induced electric current, but the magnetic field must be in motion in order to generate an electric current.

A weak magnetic field can still generate an electric current in a wire if it is in motion with respect to the wire.

If a magnetic field is at rest, it will not induce an electric current in a wire. The magnetic field must be in motion in order to generate an electric current.

Thus, the correct answer is D) in motion.
