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
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.

Lee knew that certain events occur to create new material in the process of sea-floor spreading. Rearrange the steps into the correct order by placing the event that happens first at the top. Place the event that occurs last at the bottom.
Answer:
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. ... As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

Answer:
Explanation:
A withered plant. Unless the plant is one of the many plants that have huge water retention capacity, for example, cactus. Such plants also don't need water to gr6, they just need a tiny amount of water, ba sufficient sunlight to enable them complete photosynthesis.
Any other plants asides one of the many like that, he will definitely come back to a dead, or at best, withered plant. A month is too long a time to not take care of your plant and expect it to still be up and running
What is the momentum of a 4 kg object moving west at 4 m/s?*
O 12 kg*m/s (east)
O 1.33 kg*m/s (west)
O 16 kg*m/s (east)
16 kg*m/s (west)
Answer:
16kg*m/s west
Explanation:
P=M*V
Momentum= Mass time velocity, plug it into the formula,
M is 4 and V is 4, 4*4=16, and since the object is moving west its going to be west.
basically saying in simpler terms,
16=4*4

A.)strong
B.)weak.
C.)at rest.
D.)in motion.
Answer:a stro
Explanation:
A magnet can generate an electric current in a wire if the magnet is close enough to the wire and if the magnet is also in motion. The correct answer is D) in motion.
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.

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
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 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
