As a geologist, you come across a landscape with a massive fault zone that
produces a lot of large earthquakes but has no volcanoes. What type of plate
boundary is this? What are the movements of plates there? Where is this type
of boundary found in California?
Answer:
At a convergent boundary where both plates are continental, mountain ranges grow and earthquakes are common. At a transform boundary, there is a transform fault and massive earthquakes occur but there are no volcanoes. Processes acting over long periods of time create Earth's geographic features.

If a ball that is 10 meters above the ground is thrown horizontally at 5.51 meters per second. a. how long will it take for the ball to hit the ground? b. how far will the ball travel in the horizontal direction before it hits the ground?
Answer:
a. t = 1.43 s
b. d = 7.88 m
Explanation:
a. The time of flight can be found using the following equation:
[tex] y_{f} = y_{0} + v_{0_{y}}t - \frac{1}{2}gt^{2} [/tex]
Where:
[tex]y_{f}[/tex]: is the final height = -10 m
[tex]y_{0}[/tex]: is the initial height = 0
[tex]v_{0_{y}}[/tex]: is the initial speed in the vertical direction = 0
g: is the acceleration due to gravity = 9.81 m/s²
By solving the above equation for "t" we have:
[tex] t = \sqrt{\frac{2y_{f}}{g}} = \sqrt{\frac{2*10 m}{9.81 m/s^{2}}} = 1.43 s [/tex]
Hence, the ball will hit the ground in 1.43 s.
b. The distance in the horizontal direction can be found as follows:
[tex] x_{f} = x_{0} + v_{0}t + \frac{1}{2}at^{2} [/tex]
Where:
x₀: is the initial position in the horizontal direction = 0
a: is the acceleration in the horizontal direction = 0 (it is moving at constant speed)
[tex] x_{f} = 5.51 m/s*1.43 s = 7.88 m [/tex]
Therefore, the ball will travel 7.88 m before it hits the ground.
I hope it helps you!

A rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s. Which statement
correctly describes the momentum of the rubber ball?
a. Its magnitude increased and its direction changed.
b. Its magnitude increased but its direction remained the same.
c. Its magnitude remained the same but its direction changed.
d. Its magnitude and its direction both remained the same.
Answer:
d. Its magnitude and its direction both remained the same.
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
[tex] Momentum = mass * velocity [/tex]
The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.
This ultimately implies that, the law of conservation of momentum states that if objects exert forces only on each other, their total momentum is conserved.
In this scenario, a rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s. Thus, the statement which correctly describes the momentum of the rubber ball is that its magnitude and its direction both remained the same because its velocity didn't change while returning to the thrower.
The correct statement should be "Its magnitude remained the same but its direction changed". Option C is correct.
Given information:
A rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s.
Now, the mass of the ball doesn't change and the magnitude of the velocity is also the same.
Momentum can be defined as the product of mass and velocity. It is a vector quantity because velocity is also a vector quantity, and it has magnitude and direction.
Now, the magnitude of momentum will be the same because mass and velocity don't change in magnitude.
The direction of velocity will be reversed. So, the direction of momentum will also be reversed.
Therefore, the correct statement should be "Its magnitude remained the same but its direction changed". Option C is correct.

Bode made a rocket using an empty plastic bottle and fins made out of cardboard. After partially filling the bottle with water, he
pumps air into the bottle using a pump attached to the rocket with plastic tubes. When the pressure in the bottle becomes high
enough the water gushes out and launches the rocket into the air, as shown in the diagram below.

How does the force that causes the water to leave the rocket compare to the force that causes the rocket to launch?
They are ental
Answer:They are equal and act in opposite directions.
Explanation:Newton's third law of motion states that for every action there is an equal and opposite reaction. In the case of Bode's rocket, the pressurized air in the bottle forces the water to gush downward out of the bottle, causing the rocket to launch upward into the air. The force of the water gushing downward is equal to the upward force on the rocket. So, the two forces are equal and act in opposite directions.
The force that causes the water to leave the rocket compared to the force that causes the force to launch is equal but opposite in direction.
What is Newton's law?There is a threes law given by the scientist newton in relation to the motion. The first law tells that if a body is in stop mode, then they become in motion once an external force is applied to them. The second law tells that force is equal to the product of mass and acceleration of the body. The third law tells that if you apply force to an object, then the object also applies force in reaction.
According to Newton's third law, the rocket applies force to the water, then the water also exerts a force on the rocket.
In the instance of Bode's rocket, the bottle's pressured air causes the water to pour out of the bottle downward, which causes the rocket to shoot upward into the air. The upward force on the rocket is equivalent to the force of the water pouring down. Therefore, the two forces are equivalent and exert opposing forces.

A force of 900 N pushes a wedge 0.10 m into a log. If the work done on the log is 50 J, what is the efficiency of the wedge?
HELPPPP
Answer:
55.56%
Explanation:
We'll begin by calculating the work done in pushing the wedge. This can be obtained as follow:
Force (F) = 900 N
Distance (s) = 0.1 m
Workdone (Wd) =..?
Wd = F × s
Wd = 900 × 0.1
Wd = 90 J
Finally, we shall determine the efficiency. This can be obtained as follow:
Work output = 50 J
Work input = 90 J
Efficiency =?
Efficiency = work output / work input
Efficiency = 50 / 90 × 100
Efficiency = 55.56%
Thus, the efficiency is 55.56%

What latitudes experience both summer and winter?
There are only two times of the year when the Earth's axis is tilted neither toward nor away from the sun, resulting in a equal amount of daylight and darkness at all latitudes. These events are referred to as Equinoxes.The word equinox is derived from two Latin words - aequus (equal) and nox (night). At the equator, the sun is directly overhead at noon on these two equinoxes. How do the climatological temperature patterns follow the four seasons? The temperatures are pretty much the same when comparing early winter to late winter and pretty much the same when comparing early summer to late summer. However, late Fall is much colder than early Fall and late Spring is much warmer than early Spring. Why is that? The reason is linked to the changing of the solar sun angle during each season. In the Fall, the sun angle is always getting lower and in the Spring it is always getting higher. From this it would make sense that late Fall is much colder than early Fall and late Spring is much warmer than early Spring. In the winter, the sun angle is INCREASING and in the summer the sun angle is DECREASING. This fact causes temperatures to be pretty much the same when comparing early winter to late winter and pretty much the same when comparing early summer to late summer. The cumulative cooling of the ground and ocean is partially offset by an increasing sun angle in the winter and the cumulative warming of the ground and ocean is partially offset by a decreasing sun angle in the summer. This causes the Spring and Fall seasons to seem much quicker in duration than the Summer and Winter seasons.

What is the speed of a 180 g ball if its kinetic energy is 100 J?
Answer:
Velocity, V = 33.33 m/s
Explanation:
Given the following data;
Mass = 180grams to kilograms = 180/1000 = 0.18 kg
Kinetic energy = 100J
To find the speed;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the equation, we have;
100 = ½*0.18*V²
Cross-multiplying, we have;
200 = 0.18*V²
V² = 200/0.18
V² = 1111.11
Taking the square root of both sides, we have;
Velocity, V = 33.33 m/s
