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.

Calculate the momentum of a boat with a mass of 95kg moving at 2m/Ss
Answer:
190 kg m/s
Explanation:
Momentum = Velocity × Mass
→ Substitute in values
2 × 95 = 190 kg m/s
The momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.
What is Momentum?Momentum is defined as the product of mass of velocity. Momentum is a vector quantity. Mathematically, we can write momentum as -
p = mv
It is also the measure of the impact force imparted by any moving object, when it comes in contact with some other body.
Given is a boat with a mass of 95 Kg moving at 2 m/s.
Mass [m] = 95 Kg
Velocity [v] = 2m/s
We can write the momentum as -
p = mv
Substituting values, we get -
Momentum [p] = 95 x 2 = 190 Kg m/s
p = 190 Kg m/s
Therefore, the momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.

How does the sun maintain its high temperature and energy output?
Answer:
The core of the sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into nuclei of helium (He). ... The core is the only part of the sun that produces an appreciable amount of heat through fusion.
Explanation:
I got you
By not running out of fuel (Hydrogen).
Rest assured ... When the sun runs low on Hydrogen, it'll go through several complex changes, and it'll end up at much much lower temperature, with much much lower energy output.
If an engine can produce 670 J of energy in 1 min, how many watts can it output?
Answer:
11.2Watts
Explanation:
Given parameters:
Energy produced by the engine = 670J
Time taken = 1min = 60s
Unknown:
Number of watts it can output = ?
Solution:
This problem entails finding the power of the engine.
Power is the rate at which work is being done.
So;
Power = [tex]\frac{Work done }{time}[/tex]
Power = [tex]\frac{670}{60}[/tex] = 11.2Watts

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 bag weighing 20 N is pushed horizontally a distance of 35 m across a
level floor by a force of 10 N, How much work is done on the bag in
Joules? W=Fd *
Answer:
350J
Explanation:
Given parameters:
Weight of bag = 20N
Distance moved horizontally = 35m
Force applied = 10N
Unknown:
Work done on the bag = ?
Solution:
Work done is the force applied to move a body through given distance.
Work done = Force applied x distance
So;
Work done = 10 x 35 = 350J

The density will be
d_lead = 113/ V
d_aluminum = 27/V
It does not matter for this question what the volume actually is. Just note that the value of the volume is the same for each ball.

B: incorrect. If the density of the two balls was less than water, the two balls would float. Never going to happen unless the balls are thin shells.
C: incorrect. The exact opposite is the answer.
D: Correct. This is the answer.

Find the electric field E⃗ (r⃗ )E→(r→)E_vec(r_vec) inside the sphere (for rrr< aaa) in terms of the position vector r⃗ r→r_vec. Express your answer in terms of r⃗ r→r_vec, rhorhorho (Greek letter rho), and ϵ0ϵ0epsilon_0.
Solution :
Using the Gauss law, the electric field intensity of a sphere is given by :
[tex]$E. 4 \pi r^2 = \frac{Q_{enc}}{\epsilon_0}$[/tex]
[tex]$E = \frac{Q_{enc}}{4 \pi r^2 \epsilon_0}$[/tex]
Now the enclosed charge inside the sphere (r<a) is
[tex]$Q_{enc}= \rho V$[/tex]
[tex]$Q_{enc}= \rho \left( \frac{4}{3} \pi r^3 \right)$[/tex]
Hence, the electric field intensity becomes as follows :
[tex]$E= \frac{\rho \left(\frac{4}{3} \pi r^3\right)}{4 \pi \epsilon_0 r^2}$[/tex]
[tex]$E =\frac{\rho r}{3 \epsilon_0}$[/tex]
Thus, the electric field inside the sphere is given by :
[tex]$\vec {E} = \frac{\rho \vec{r}}{3 \epsilon_0}$[/tex]

Which equation should be used to calculate the speed of a wave?
speed = frequency x wavelength
speed = frequency x hertz
speed = period x wavelength
speed = period x hertz
The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.
What is the formula for wave speed?The speed of a wave is calculated by the equations: V = λ . f or V = λ/T, and the unit of measurement is m/s. This speed depends on the medium: in gaseous media, the speed is lower than in solid media.
See more about wave speed at brainly.com/question/10715783
The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.
What is Speed of wave?Wave speed is the movement of a progressive wave, which is an energy-moving disturbance that takes the shape of an oscillation and moves from one place to another.
The wavelength and frequency of a wave both affect its speed. A wave's speed is a crucial factor because it enables us to estimate how quickly the wave will disperse in the medium, which is the substance or material that will carry it.
This is the water in the case of ocean waves and the air in the case of sound waves. The kind of wave and the physical properties of the medium in which it is flowing also affect a wave's velocity.
Therefore, The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.

The time for a sound wave to travel between two people is 0.80 s,
The people are 256 m apart
Calculate the speed of sound in air.
Answer:
Explanation:
Using the below formula
Speed of sound = ( distance between observers) *2/(total time taken)
Now putt the given values ,
time taken = 0.80 sec
distance = 256 m
hence
V of sound= 256*2/0.80
V of sound = 640 m/sec
