How does La Niña affect the climate of the Pacific Ocean?
The ocean becomes cooler.
The warm water moves toward the east.
The cold water sinks deeper into the ocean.
The strength of the prevailing winds decreases.
Answer:
The ocean becomes cooler
Explanation:
La Niña is a phase of a natural climate pattern which occurs across the tropical Pacific Ocean and swings back and forth every 3 - 7 years on the average.
Now, during La Niña, the surface winds across the entire tropical Pacific Ocean are usually stronger than they are on the average, and in return most of the tropical Pacific Ocean will become cooler than they are on average.
Thus, looking at the given options, the correct one is;
The ocean becomes cooler
The way in which La Niña affects the climate of the Pacific Ocean is that: A. The ocean becomes cooler.
La Niña is a complex oceanic and atmospheric phenomenon that occur due to variations in ocean temperatures across the equatorial band of the Pacific Ocean, at a specific period of time in years. Also, it is a colder part of the El Niño-Southern oscillation climate pattern.
Basically, La Niña causes the surface winds blowing across the equatorial band of the Pacific Ocean to be stronger while reducing tropical cyclogenesis. Consequently, this causes the climate of the Pacific Ocean to become cooler.

If we ignore air resistance (as we normally do) and launch a projectile at an angle between zero and 90o, how does the magnitude (size) of the vertical component of the velocity change as time elapses? Group of answer choices
Answer:
First, remember that:
Acceleration = dV/dt
where V is velocity and t is time.
When you launch a projectile (θ between 0° and 90° means that you are not launching it into the ground) you are applying an initial velocity v0, that can be separated in components, where the vertical component will be:
v0*sin(v)
That initial vertical velocity is a constant, so it does not depend on time.
Then when we differentiate with respect to the time, that constant will vanish, and we will get:
rate of change of the vertical velocity = vertical acceleration.
And as you know, when we ignore the air resistance the only force acting on the vertical axis is the gravitational force, such that the vertical acceleration will be:
a(t) = -9.8m/s^2
Where the negative sign is because this force points down.
Then the rate of change of the vertical velocity will be exactly that, -9.8m/s^2.
And the vertical velocity equation, to see exactly how the vertical velocity depends on time, will be:
V(t) = (-9.8m/s^2)*t + v0*sin(θ)

Which statement accurately describes the relationship between weight and
mass?
A. Mass is an object's weight multiplied by its diameter.
B. Weight is an object's mass multiplied by its diameter.
C. Mass is an object's weight multiplied by the amount of
gravitational force acting on that object.
O D. Weight is an object's mass multiplied by the amount of
gravitational force acting on that object.
Answer:
D. Weight is an object's mass multiplied by the amount of
gravitational force acting on that object.
Explanation:
I got it right on the test
Weight is an object's mass multiplied by the amount of gravitational acceleration acting on that object. Hence, option (D) is correct.
What are mass and weight?The most fundamental characteristic of matter is its mass, which is one of the fundamental physical quantities. Mass is a term used to describe how much matter is there in a body. The kilograms is the SI unit of mass.
The amount of a body's weight indicates how much gravity is pulling on it. The weight formula is as follows: w = mg Since weight is a force, it has the same SI unit as a force, which is the Newton.
When we look at how weight is expressed, we can see that it depends on both mass and the acceleration caused by gravity. Hence, weight is an object's mass multiplied by the amount of gravitational acceleration acting on that object.

Explore how a kaleidoscope works. Find two mirrors, and hold them upright on the desk, so they are at an angle to each other like an open book. Set an object between them, and look in the mirrors. How many images do you see? Slowly bring the mirrors together. What happens? Are the images you see the same? Can you explain what you see?
Answer:
there is an infinite number of images because it is reflected off of the mirrors. the images in the mirror will "move" if either mirror is shifted because the angle of reflection. the images are the same because its just a repeated reflection. i see the object on both sides, repeated as far as i can see in both mirrors.

A 30 N rock falls from a 40 m cliff. At what point during its fall are its
potential and kinetic energies equal?
Answer:
Both energies are equal when the rock has fallen 20 m or equivalently when it is at a height of 20 m.
Explanation:
Potential and Kinetic Energy
The gravitational potential energy is the energy an object has due to its height above the ground. The formula is
[tex]U=mgh[/tex]
Where:
m = mass of the object
g = acceleration of gravity (9.8~m/s^2)
h = height
Note we can also use the object's weight W=mg into the formula:
[tex]U=Wh[/tex]
The kinetic energy is the energy an object has due to its speed:
[tex]\displaystyle K=\frac{1}{2}mv^2[/tex]
Where v is the object's speed.
Initially, the object has no kinetic energy because it's assumed at rest.
The W=30 N rock falls from a height of h=40 m, thus:
[tex]U=30*40=1,200 J[/tex]
Since the sum of the kinetic and potential energies is constant:
U' + K' = 1,200 J
Here, U' and K' are the energies at any point of the motion. Since both must be the same:
U' = K' = 600 J
U'=Wh'=600
Solving for h':
[tex]\displaystyle h'=\frac{600}{W}=\frac{600}{30}=20~m[/tex]
Both energies are equal when the rock has fallen 20 m or equivalently when it is at a height of 20 m.

A marble is thrown horizontally with a speed of 7 m/s. When the marble lands, it hastraveled a horizontal displacement of 30 m. How much time was the marble in the air?
Answer:
t = 4.28 s
Explanation:
The horizontal speed of a marble = 7 m/s
The horizontal displacement covered by the marble = 30 m
We need to find the time for which the marble is in air. Let the time is t. Using the formula for speed to find it as follows :
[tex]s=\dfrac{d}{t}\\\\t=\dfrac{d}{s}\\\\t=\dfrac{30\ m}{7\ m/s}\\\\=4.28\ s[/tex]
So, it will in the air for 4.28 s.

What is the work required to lift a 10 kg box off the ground to a height of
5.0 m?
Answer:
490J
Explanation:
Given parameters:
Mass of box = 10kg
Height = 5m
Unknown:
Work done = ?
Solution:
Work done can be derived from the product of force and distance;
Work done = force x distance
Force here is applied by gravity and it is the weight
The distance is the height
Work done = weight x height
Work done = mass x acceleration due to gravity x height
Work done = 10 x 9.8 x 5 = 490J
