A friend of yours who is traveling the world reports that she recently experienced a day on which the surface wind blew from the southeast while simultaneously the clouds overhead were moving from east to west. Independently, she is made aware of the fact that on that day the PGF was the same at the surface and at the cloud height. What hemisphere was she in at the time
Answer:
At that time, she was in the southern hemisphere
Explanation:
She is witnessing the southeastern trade breeze because the cloud is passing from east to west and she is also witnessing a storm from the southeast.
Because of the Coriolis effect, which deviates the atmosphere in the left-hand side of the southern hemisphere and generates a southeastern wind, this wind did not blow directly from south to east.

A trolley is pushed with a force that causes it to move a certain distance. It moves in the
direction it is pushed
Which row in the table represents the combination of force and distance that means the
smallest amount of work is done on the trolley?
Answer:
Row D ; 280 Nm
Explanation:
Workdone is the product of the force applied and the distance moved. This means :
Workdone = Force * distance
For each of rows A to D:
Row A :
Workdone = 20 N * 20m = 400 Nm
Row B :
Workdone = 40 N * 10m = 400 Nm
Row C :
Workdone = 50 N * 6m = 300 Nm
Row D :
Workdone = 70 N *4m = 280 Nm
From the result obtained above, the smallest amount of workdone on the trolley is given in Row D ; which is 280Nm

Answer:
Resistance, R = 60 Ohms
Explanation:
Given the following data;
For the first heater;
Voltage, V = 120 V
Resistance, R = 15 Ohms
For the second heater;
Voltage, V = 240 V
To find the resistance in the second heater;
First of all, we would determine the power rating of the heaters using the formula below;
Power = voltage²/resistance
Power = 120²/15
Power = 14400/15
Power = 960 Watts
Next, we find the resistance in the second heater;
Power = V²/R
960 = 240²/R
Cross-multiplying, we have;
960R = 57600
R = 57600/960
R = 60 Ohms

A wave has a frequency of 35 Hz and a wavelength of 15 meters,
what is the speed of the wave?
Answer:
f lamda = c
Explanation:
525 m/s is the speed
A wave has a frequency of 35 Hz and a wavelength of 15 meters, Then the speed of the wave is 525 meters per second(m/s).
What is the speed of the wave?The speed of a wave is the distance that a wave travels per unit of time. It is a measure of how quickly the disturbance created by the wave is propagated through a medium. The speed of a wave can be calculated using the formula:
Speed = Frequency x Wavelength
Where the frequency = is the number of wave cycles per second
wavelength = is the distance between two consecutive points on the wave that is in phase (i.e., at the same point in their oscillation).
The speed of a wave depends on the properties of the medium through which it is traveling, such as its density, elasticity, and temperature.
Here in the question,
Speed = Frequency x Wavelength
Speed = 35 Hz x 15 meters
Speed = 525 meters per second(m/s).
Therefore, the speed of the wave is 525 meters per second.

How do attitudes help us develop our self-concept?
Answer:
Attitudes help determine self concept; but, unlike values, they are more narrowly defined. The relationship between values and attitudes is close because values are reflected in attitudes. Your attitude says something about your value system.

Down in the Gulf of Mexico how do sandbars from?
Answer:
Rip currents often form near structures in the water such as piers or jetties, when wave heights change suddenly, or most frequently when a channel is cut into a sandbar
Explanation:
If distance between particle become half, the electric force
The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.
3. A boulder drops in the water and creates a wave with a period of 2 s/cycle and a wavelength of
.75 m/cycle. How fast is the wave moving?
Answer:
The wave moves with a velocity of 37.5 m/s
Explanation:
We know that the speed of a wave is given by:
V = f*λ
Where f is the frequency (the inverse of the period)
Then:
f = 1/T
And we know that T = 2 s/cycle
f = 1/(2 s/cycle) = (1/2) cycle/s
And λ is the wavelength, we know that:
λ = 75m/cycle.
Then the speed of the wave is:
v = ( (1/2) cycle/s)*(75m/cycle) = (75/2) m/s = 37.5 m/s
Look at the distance-time graph below. It shows Angela's journey as she walks to the end of the road and back. The gradient represents Angela's __________. What one word completes the sentence?
Answer:
The gradient here represents Angela's Velocity.
Explanation:
A distance-time graph has distance on its y-axis and time on its x-axis. Therefore, the gradient of the distance-time graph is given by the following formula:
[tex]Gradient = \frac{Change\ on\ y-axis}{Change\ on\ x-axis} \\\\Gradient = \frac{Distance\ Covered\ by\ Angela}{Time\ taken\ to\ cover\ the\ distance}\\\\Gradient = Angela's\ Velocity[/tex]
Since the rate of change of distance is called the velocity.
Therefore, the gradient here represents Angela's Velocity.
A transformer has 100 turns in the primary coil and 150 on the secondary. It is a
- step-down transformer.
- decreasing transformer.
- step-up transformer.
- increasing transformer.
Answer:
This transformer would be a step-up transformer.
Explanation:
In a transformer, the primary coil is connected to the AC input while the secondary coil is connected to the AC output.
Let [tex]V_P[/tex] and [tex]N_P[/tex] denote the primary voltage (at the input) and number of turns in the primary coil.
Let [tex]V_S[/tex] and [tex]N_S[/tex] denote the secondary voltage (at the output) and the number of turns in the secondary coil.
Ideally, the voltage in each coil would proportional to the number of turns in that coil:
[tex]\displaystyle \frac{V_S}{V_P} = \frac{N_S}{N_P}[/tex].
For example, in this question, [tex]N_P = 100[/tex] (primary coil, connected to the AC input) whereas [tex]N_S = 150[/tex] (secondary coil, connected to the AC output.)
[tex]N_S = 1.5 \, N_P[/tex]. Accordingly, the voltage in the secondary coil (AC output) would be approximately [tex]1.5[/tex] times the voltage in the primary coil (AC input): [tex]V_S = 1.5\, V_P[/tex].
Hence, the secondary voltage of this transformer (AC output) would exceed the primary voltage (AC input.) This transformer would be a step-up transformer.

A 70.0 kg sprinter accelerates at a rate of 5.00 m/s2. What is the net force generated by the sprinter?
Answer:
F = 350 N
Explanation:
Force Equation
F=ma
Newton's second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object's mass multiplied by its acceleration. We use Newtons, kilograms, and meters per second squared as our default units, although any appropriate units for mass (grams, ounces, etc.) or velocity (miles per hour per second, millimeters per second2, etc.) could certainly be used as well - the calculation is the same regardless.
How to solve
Formula: FNet = Fa + Fg.
F = m * a
F = 70.0 kg × 5.00 m/s2
F = 350 N
Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

2. Compare and Contrast A fault cuts through
two layers of rock. Above sits a layer of sand-
stone. How does the age of the fault compare
to the ages of all three rock layers?
Explanation:
The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through. The fault labeled "E" cuts through all three sedimentary rock layers (A, B,and C) and also cuts through the intrusion (D). So the fault must be the youngest formation that is seen and known of.
The age of the fault A is in between rock B and intrusion D. Hence A is the youngest rock and C be the oldest rock here.
What are faults?A fault is a crack or region of cracks that separates two rock blocks. The blocks might move in relation to one another due to flaws. This movement may happen suddenly, like an earthquake, or it may happen gradually, like creep.
From a few millimeters to thousands of kilometers, faults can vary in length. Over geologic time, most faults cause recurrent displacements. The rock on one side of the fault abruptly shifts in relation to the other during an earthquake. The fault surface may be vertical, horizontal, or at any other arbitrary angle.
The principal of superposition states that, the oldest layer will be the bottom of the young rocks. Here, rock is A is above B and C. Hence, rock A is youngest than layer B and C.

A particle of mass M is moving in the positive x direction with speed v. It spontaneously decays into 2 photons, with the original particle disappearing in the process. One photon has energy 233 MeV and moves in the positive x direction, and the other photon has energy 21 MeV and moves in the negative x direction. (5) (a) Draw a picture of this process. What is the total relativistic energy of the particle before its decay
Solution :
Mass of the particle = M
Speed of travel = v
Energy of one photon after the decay which moves in the positive x direction = 233 MeV
Energy of second photon after the decay which moves in the negative x direction = 21 MeV
Therefore, the total energy after the decay is = 233 + 21
= 254 MeV
So by the law of conservation of energy, we have :
Total energy before the decay = total energy after decay
So, the total relativistic energy of the particle before its decay = 254 MeV
