Earth's rotation and spherical shape cause winds to veer to the right (in the northern Hemisphere) or to the left (in the southern Hemisphere) of the direction they want to go. This is known as the Coriolis effect.
If you didn't know that you're on a rotating Earth, and you looked at the patterns of the winds, you'd think there's some kind of force that's making the airflow veer to the right or left of the direction it actually wants to go. This is known as the Coriolis force. It's a"pseudo force", because it doesn't really exist. It only LOOKS like it's there, because of the Earth's rotation and spherical shape..
The statement "Earth's rotation causes winds to veer to the west or to the east" is true about the Coriolis effect.
What is the Coriolis effect?Fluid materials such as wind and ocean currents take different directions depending on the hemisphere, this movement of deviation is called the Coriolis effect.
Characteristics of the Coriolis effectThe Coriolis effect occurs when masses of air or water move along terrestrial meridians, and their trajectory and speed are modified by it.The winds or ocean currents that move along a meridian are diverted by accelerating in the direction of rotation (east) if they go towards the poles or the opposite (west) if they go towards the equator.Therefore, we can conclude that the force that tends to deflect the trajectory of objects moving across the entire earth's surface is known as the Coriolis effect.

What is the cost of operating a 100 W light bulb for "4 hrs per day" for 30 days, if the cost of electricity is 6 cents kW•h
Answer:
the cost of operating the light bulb is 72 cents.
Explanation:
Given;
cost of electricity, C = 6 cents / kW.h
power of light bulb, P = 100 W
time of light power consumption, t = 4 hours per day for 30 days
total time = 4 hours x 30 = 120 hours
Power consumed by the light bulb is calculated as;
P = 100 x 120 = 12000 w.h = 12 kW.h
Cost of power consumption = 6 cents/kWh x 12 kWh
= 72 cents
Therefore, the cost of operating the light bulb is 72 cents.
3,000ml of an unknown liquid has a mass of 3 kg. What is its density?
Answer:
Ro = 1000 [kg/m³]
Explanation:
We must remember that density is defined as the relationship between mass and volume.
[tex]Ro=m/V\\[/tex]
where:
Ro = density [kg/m³]
m = mass = 3 [kg]
V = volume = 3000 [ml]
We must convert the volume of milliliters to cubic meters
[tex]3000[ml]*\frac{0.001Lt}{1ml}*\frac{1m^{3} }{1000Lt} = 0.003m^{3}[/tex]
Now replacing:
[tex]Ro=3/0.003\\Ro=1000[kg/m^{3} ][/tex]

which statements describe kinetic and potential energy? check all that apply.
Answer:
ACDE
Explanation:
Energy is generally described as the ability to do work by a body. There are two main forms of energy which are the kinetic energy and the potential energy.
Other energy forms stems from these two energy types.
Potential energy expressly deals with the position of a body. It is mathematically given as:Potential energy = mass x acceleration due to gravity x height
It is the energy stored based on the position of particles within a mediumThese description satisfies options A, C
Kinetic energy is the energy due to the motion of body. It is mathematically given as:Kinetic energy = [tex]\frac{1}{2}[/tex] x mass x velocity²
Also, kinetic energy is directly proportional to the velocity of a body.The description satisfies DE

A ball rolls with a speed of 3 m/s across a level table that is 1.5m above the floor. How far along the floor is the landing spot from the table?
Answer:
d = 1.65 m
Explanation:
Given that,
The speed of a ball, v = 3 m/s
A ball rolls a level table that is 1.5 m above the floor.
We can find how long the ball is in free fall. We can use the second equation of kinematics as follows :
[tex]s=ut+\dfrac{1}{2}gt^2[/tex]
u is the initial speed in the vertical direction
So,
[tex]s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 1.5}{9.8}} \\\\t=0.55\ s[/tex]
Now, using the formula of velocity.
[tex]v=\dfrac{d}{t}\\\\d=vt\\\\d=3\times 0.55\\\\d=1.65\ m[/tex]
So, the landing spot is at 1.65 m from the table.

Get It? Explain Using the equation for translational kinetic energy,
show why a car moving at 20 m/s has four times the translational
kinetic energy of the same car moving at 10 m/s.
Answer:
[tex]K_1=4K_2[/tex]
Explanation:
Kinetic energy is given by
[tex]K=\dfrac{1}{2}mv^2[/tex]
m = Mass of object
v = Velocity of object
Here mass is constant so
[tex]K\propto v^2[/tex]
[tex]v_1[/tex] = Intial velocity of the car = 20 m/s
[tex]v_2[/tex] = Final velocity of the car = 10 m/s
[tex]\\dfrac{K_1}{K_2}=\dfrac{v_1^2}{v_2^2}\\\Rightarrow \dfrac{K_1}{K_2}=\dfrac{20^2}{10^2}\\\Rightarrow \dfrac{K_1}{K_2}=4\\\Rightarrow K_1=4K_2[/tex]
So, a car moving at 20 m/s has four times the translational kinetic energy of the same car moving at 10 m/s.

Suppose a 4.0-kg projectile is launched vertically with a speed of 8.0 m/s. What is the maximum height the projectile reaches?
A. 1.7 m
B. 3.3 m
C. 6.5 m
D. 13 m
help as quick as possible plz :(
Answer:
h = 3.3 m (Look at the explanation below, please)
Explanation:
This question has to do with kinetic and potential energy. At the beginning (time of launch), there is no potential energy- we assume it starts from the ground. There, is, however, kinetic energy
Kinetic energy = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]
Plug in the numbers = [tex]\frac{1}{2}[/tex](4.0)([tex]8^{2}[/tex])
Solve = 2(64) = 128 J
Now, since we know that the mechanical energy of a system always remains constant in the absence of outside forces (there is no outside force here), we can deduce that the kinetic energy at the bottom is equal to the potential energy at the top. Look at the diagram I have attached.
Potential energy = mgh = (4.0)(9.8)(h) = 39.2(h)
Kinetic energy = Potential Energy
128 J = 39.2h
h = 3.26 m
h= 3.3 m (because of significant figures)

Why do you think spacecraft that carry instruments to collect data about objects in space are called probes?
Answer:
my mind cant comprehend a shing word u just said
Explanation:
The probes collect data, they capture the movement in space, therefore, spacecraft that carry instruments to collect data about objects in space are called probes, So the given statement is correct.
What are Probes?
Any conductor that is placed into a plasma and gathers current is a probe. Measurements of the current on the probe as a function of the bias potential given to the probe can be used to identify a plasma's properties.
Such probes affect their surroundings while directly detecting electron and ion flows in the plasma. Any conductive material (wire, foil, chamber walls, etc.) can serve as a plasma probe; nevertheless, precise control over the probe's size, shape, and substance is necessary to achieve detectable plasma levels. Astronauts are not present aboard probes. Scientists can analyze the data the probes relay back to Earth. Sputnik 1 was the first spacecraft to launch.
Because probes probably collect data, they capture the movement in space, therefore, spacecraft that carry instruments to collect data about objects in space are called probes.

what is inertia and how is it related to the newton's first law of motion?
Answer:
Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.
Explanation:
Some sort of a local field, maybe not our A field, is really the cause of inertia. When you push on an object a gravitational disturbance goes propagating off into either the past or the future. Out there in the past or future the disturbance makes the distant matter in the universe wiggle.

what is the difference between speed and velocity?
Explanation:
The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.

Answer:
Generally speaking, scientists have developed four different methods of determining the age of the earth. By using these methods, or a combination of them, the age of geological formations created by past events and even the fossilized bones of prehistoric animals can be determined.
Based on the research done by scientists, the Geologic Column, a graph that illustrates earth age, was developed. The Column, with its names for the epochs and eras of time, illustrates what scientists think was taking place in earth history. A small version of the Geologic Column is pictured at the right.
