Erosion is the process by which soil and sediments are moved by gravity, wind, and water. Erosion occurs naturally, but it can be accelerated by human activity. Which of these human activities most contributes to soil erosion?
biking on forest trails
boating on a lake
cutting down trees
fertilizing a lawn
Answer:
Cutting down trees
Explanation:
The roots of trees often hold settiments in place, thus removing these strong natural barriers makes it easier for erosion to occur.
A hockey puck sliding on a frozen lake comes
to rest after traveling 176 m.
If its initial velocity is 2.3 m/s, what is its
acceleration
Given parameters:
Distance traveled = 176m
Initial velocity = 2.3m/s
Unknown:
Acceleration = ?
Solution:
Acceleration is the change in velocity with time. To solve this problem, we apply one of the motion equations;
V² = U² + 2as
where V is the final velocity
U is the initial velocity
a is the acceleration
s is the distance
final velocity is 0;
0² = 2.3² + 2 x a x 176
-5.29 = 352a
a = - [tex]\frac{5.29}{352}[/tex] = - 0.015m/s²

A population of lobsters was recently exposed to a new disease. Which type of limiting factor is this disease and what will be its predicted impact on the carrying capacity of this population? Group of answer choices density independent; the carrying capacity will increase density dependent; the carrying capacity will decrease density dependent; the carrying capacity will increase density independent; the carrying capacity will be reduced
Answer:
the carrying capacity will decrease density dependent
Explanation:
The limiting factor of the disease is density dependent and will decrease the carrying capacity of the population because the disease that affect the population operate when the number of organisms in per unit area get to a specific level , it's affected the population when the population per unit are reached a certain level and the disease decrease the carrying capacity of the population. Carrying capacity is the average population size of organisms in an habitat. As the lobsters population is affected by disease, the population sizes reduced because many of the lobsters would of died and inactive, thereby causing a reduction in the size and capacity.

A dolphin can swim at a constant speed of 12.5 m/s. How
long does it take a dolphin to swim 45 meters?
Answer:
[tex]\boxed {\tt 3.6 \ seconds}[/tex]
Explanation:
Time can be found by dividing the distance by the speed.
[tex]t=\frac{d}{s}[/tex]
The distance is 45 meters and the speed is 12.5 meters per second.
[tex]d= 45 \ m \\s= 12.5 \ m/s[/tex]
[tex]t=\frac{45 \ m}{12.5 \ m/s}[/tex]
Divide. Note that the meters, or "m" will cancel each other out.
[tex]t=\frac{45 }{12.5 \ s}[/tex]
[tex]t=3.6 \ s[/tex]
It will take the dolphin 3.6 seconds to swim a distance of 45 meters are 12.5 meters per second.

b. 2.54x10^-8N, to the right
c. 3.4x10^-8N, to the left
d. 3.4x10^-8N, to the right
Answer is A 2.8 x 10^-8 N, to the right
The net gravitational force on mass A due to masses B and C is required.
The correct option is a. [tex]2.8\times 10^{-8}\ \text{N}[/tex] to the right.
G = Gravitational constant = [tex]6.674\times 10^{-11}\ \text{Nm}^2/\text{kg}^2[/tex]

Your science teacher presents you with a circuit model that contains five light bulbs, a switch, and a 1.5-volt battery. The wires of the circuit are hidden from your view so that you cannot see how the bulbs are connected to the battery. How could you determine the type of circuit used in this model?
A.
If all the bulbs are equal brightness, it is a series circuit because each bulb in a series circuit has the same resistance.
B.
If all the bulbs are equal brightness, it is a parallel circuit because each bulb in a parallel circuit has its own path to the battery.
C.
If you unscrew one bulb and all the others stay lit, it is a parallel circuit because each bulb in a parallel circuit has its own path to the battery.
D.
If you unscrew one bulb and all the others stay lit, it is a series circuit because each bulb in a series circuit have to share the same current.
Answer:
C
Explanation:
PLACING BULBS IN SERIES
Increasing the number of bulbs decreases the brightness of the bulbs.
The resistance increases. In a series circuit, adding bulbs increases the resistance in the circuit. A complete circuit requires the electrons to move from the negative terminal of the battery to the positive terminal. When one bulb is unscrewed it opens the circuit preventing a complete circuit and the electrons cannot return to the battery.
PLACING BULBS IN PARALLEL
Two bulbs in parallel are brighter than two bulbs in series. In a parallel circuit each bulb is in its own circuit. As bulbs are added the resistance in the circuit decreases since each circuit is another pathway for electrons to move from one end of the circuit to the other.
If you unscrew one bulb and all the others stay lit, it is a parallel circuit because each bulb in a parallel circuit has its own path to the battery.
What is bulbs in series combination?The brightness of the bulbs reduces as the number of bulbs increases in series. Resistance rises in intensity. Adding bulbs to a series circuit raises the circuit resistance. The electrons must pass from the battery's negative to positive terminals in order for the circuit to be complete. When one bulb is removed, the circuit is broken, making it impossible for the electrons to return to the battery.
What is bulbs in parallel combination?In comparison to two bulbs in series, two bulbs in parallel are brighter. Each bulb is in its own circuit when the circuits are parallel. As more bulbs are added, the resistance in the circuit reduces because each additional circuit provides an additional route for electrons to travel from one end to the other.
You can determine the type of circuit used in this model by unscrewing one bulb and all the others stay lit, it is a parallel circuit because each bulb in a parallel circuit has its own path to the battery. Hence, option(C) is correct.

Explanation:
A mortar shell is accidentally shot straight up with an initial speed of 147 m/s. How long does it take for the shell to reach its maximum height? How high does the shell rise? If the shell falls straight down after is stops, what is its velocity when it hits the ground? What is the total time the shell is in the air?
Answer:
1) t ≈ 14.985 seconds
2) The maximum height reached ≈ 1101.4 meters
3) The velocity with which it hits the ground = 147 m/s
4) The total time in the air ≈ 29.969 seconds
Explanation:
1) The given information are;
The initial velocity of the mortar shell = 147 m/s
The direction of the mortar shell = Vertically upwards
Therefore, we have, from the equation of motion
v = u - g·t
Where;
v = The final velocity = 0 at maximum height
u = The initial velocity = 147 m/s
g = The acceleration due to gravity = 9.81 m/s²
Therefore, we have;
0 = 147 - 9.81 × t
9.81 × t = 147
t = 147/9.81 ≈ 14.985 seconds
t ≈ 14.985 seconds
2) From the equation of motion, v² = u² - 2×g×s
Where;
s = The maximum height reached
We have;
0² = 147² - 2×9.81×s
2×9.81×s = 147²
s = 147²/(2×9.81) ≈ 1101.4 meters
The maximum height reached ≈ 1101.4 meters
3) The velocity with which it hits the ground is equal to the initial velocity = 147 m/s
4) The total time in the air = 2 × The time it takes to reach maximum height
The total time in the air = 2 × 14.985 ≈ 29.969 seconds
The total time in the air ≈ 29.969 seconds
