On a camping trip on the Oregon coast, you decide to hike to the ocean, but you are not sure of the direction. The time is 4:00 P.M. How might the breeze help you find the ocean? Explain.
Answer:
Because of the time, the breeze is blowing cold towards the ocean. It has to do with wind drafts.
Sea breeze come from ocean to land area. Hence, travelling against sea breeze, you get direction of the coast.
What is sea breeze?Any wind that flows from a big body of water onto a landmass is called a sea breeze. Sea breezes form as a result of changes in air pressure brought on by the different heat capacities of water and dry land.
Sea breezes are therefore more confined than prevailing winds. A sea wind is frequently seen along coasts after sunrise because land warms up far more quickly than water does when exposed to solar radiation. After sunset, a sea breeze diminishes and the wind shifts to flowing from the land towards the sea.
During afternoon ( 4.00 PM), sea breeze come from ocean to land area. Hence, travelling against this breeze, you get direction of the coast.

49. In what direction does the force of friction act?
2. Two charges are attracted to each other with a force of eight units. If the charge of one of the two
doubles and the distance between the two objects remains the same, what will be the new force of
attraction between the two objects? Explain your answer.
Answer:
16
Explanation:
The formula for the force of attraction between two charges is [tex]\frac{k\cdot q_1q_2}{r^2}[/tex], where k is a constant, [tex]q_1[/tex] is the first charge, and [tex]q_2[/tex] is the second charge. As you can see, if the radius or distance increases by 2, the force decreases by 4 because it grows exponentially. However, if the charge of one of the particles increases by 2, the force between the two also increases by 2. Therefore, the new force will be 8*2=16. Hope this helps!
The new force of attraction between the two objects is;
F_new = 2F
The formula for force of attraction between two objects is;
F = kq1•q2/r²
Where;
k is coulombs constant
q1 is charge of first object
q2 is charge of second object
r is distance between both objects
Now we are told that the charge of one of the two object doubles and the distance between them remains the same.
This means q1 is now 2q1.
Thus;
F_new = k(2q1) × q2/r²
>> F_new = 2(kq1•q2/r²)
Thus, new force of attraction between both objects will be twice the initial force of attraction which is 2F.

What is the force of friction on the
toy?
(Hint: You do NOT need to know the
coefficient of friction.)
Answer:
-2.1 N
Explanation:
The force of friction on the toy is 2.10 N and it acts opposite to the direction of its motion.
What is friction?A force called friction prevents one solid object from rolling or sliding over another. Although frictional forces, such the traction required to walk without slipping, may be advantageous, they can provide a significant amount of resistance to motion.
Given parameters:
mass of the toy dog: M = 0.398 kg.
Applied force: F = 4.63 N.
Angle of application of force: θ = 63.0°
Hence, horizontal component of applied force = F cosθ
= 4.63 × cos63.0° N
= 2.10 N.
As the child drags a 0.398 kg toy dog across flat ground at constant speed, this component of applied force is nullified by force of friction.
Hence, the force of friction on the toy is 2.10 N and it acts opposite to the direction of its motion.

What is the maximum amount of potassium nitrate (KNO3) that can dissolve in 100 grams of water at 40°C?
A.
25 grams
B.
50 grams
C.
62 grams
D.
75 grams
Answer: 62 gram
Explanation:
Using attached solubility graph
This solubility graph tells us the amount of potassium nitrate that can be dissolved per 100g of water in order to have a saturated solution of potassium nitrate at a given temperature.
In order to find the solubility of the salt at 40∘C, start from the 40∘C mark on the graph and move up until you intersect the curve. At the point of intersection, move left until you intersect the y axis and read off the value that you land on.
In this case, you can estimate that the solubility of potassium nitrate in water at 40∘C is equal to about 62g
This tells you that a saturated solution of potassium nitrate will hold about 62 g of dissolved salt, i.e. of dissociated salt, per 100g of water at 40∘C.

1. A 2 C charge moving at 15 m/s enters into a magnetic field of strength 8
T. What is the maximum force experienced by this charge? *
Answer:
Maximum force on the charge is 240 N
Explanation:
We have given charge q = 2C
Speed of the charge v = 15 m/sec
Magnetic field B = 8 T
It is known that magnetic force on the moving charge is given by
[tex]F=qvBsin\Theta[/tex]
Maximum force will be equal to
[tex]F=qvB[/tex]
[tex]F=2\times 15\times 8=240N[/tex]
Therefore maximum force on the charge is 240 N
Final answer:
The maximum force experienced by a 2 C charge moving at 15 m/s in an 8 T magnetic field is 240 N, assuming the charge moves perpendicular to the magnetic field.
Explanation:
The maximum force experienced by a 2 C charge moving at 15 m/s in a magnetic field of 8 T can be calculated using the formula F = qvB sin θ, where q is the charge, v is the velocity, B is the magnetic field strength, and θ is the angle between the velocity and the magnetic field. Assuming the maximum force occurs when the charge moves perpendicular to the magnetic field (θ = 90 degrees), the sine of 90 degrees is 1, simplifying our calculation to F = qvB. Thus, the maximum force is F = (2 C)(15 m/s)(8 T) = 240 N.

10.0-newton object to a maximum vertical height of
A) 6.00 m B) 36.7 m C) 360. m D) 600. M
Answer:
Explanation:
Given that,
Amount of energy consumed by a 60W light bulb for 1 minutes
P = 60 W
t = 1 mins = 60seconds
This energy can be used to lift a body that weight 10N
W = 10N
This shows that the electrical energy is converted to potential energy
Let calculate the electrical energy
Power is the rate of doing work
Power = Work / time
Therefore, work = power × time
Work = 60 × 60
Work = 3600 J
Potential energy can be calculated using
P.E = mgh
Where, weight is
W = mg
Then, P.E = W•h
P.E = 10•h
Then,
Potential energy, = Electrical energy
P.E = Work
10•h = 3600
Divide both sides by 10
h = 3600 / 10
h = 360m
So, the object will be lifted to a height of 360m
Answer:

A graph titled Position versus time for with horizontal axis time (seconds) and vertical axis position (meters). A straight blue line runs with an upward slope from 0 seconds 3 meters to 4 seconds 15 meters.
The starting position of this object is
m.
The object is traveling at a velocity of
m/s.
Final answer:
The question involves analyzing a position vs. time graph to determine the object's starting position at 3 meters and its velocity, which is calculated as 3 m/s based on the slope of the line.
Explanation:
The question pertains to analyzing a position vs. time graph of an object in motion to determine its starting position, velocity, and other characteristics of its motion. Given the description of a graph where a straight blue line runs with an upward slope from 0 seconds at 3 meters to 4 seconds at 15 meters, we can infer several key details about the object's movement.
The starting position of this object is 3 meters. This is inferred from the graph's indication that at 0 seconds, the object is at 3 meters.
The object is traveling at a velocity calculated from the slope of the line on the position vs. time graph. The velocity can be found using the formula velocity = (final position - initial position) / (final time - initial time). Substituting the given values, velocity = (15 meters - 3 meters) / (4 seconds - 0 seconds) = 12 meters / 4 seconds = 3 m/s.
This scenario highlights the concepts of initial position, velocity, and the relationship between slope on a position vs. time graph and the velocity of an object in motion.
the instantaneous speed at 2 seconds is **0 m/s** since the position remains constant, and the average speed over the entire trip is **1 m/s** based on the information provided by the position-time graph.
To determine the instantaneous speed at 2 seconds and the average speed over the entire trip from the given position-time graph with three straight segments, we can analyze the information provided. Here's how we can approach this:
1. **Instantaneous Speed at 2 Seconds**:
- Since the graph provides position values at specific time points, we can find the instantaneous speed at 2 seconds by looking at the slope of the graph at that point.
- At 2 seconds, the position is not explicitly given. We can infer it based on the straight segments. The position remains constant at 12 meters from 4 seconds to 6 seconds.
- Therefore, at 2 seconds, the position is 12 meters. To find the instantaneous speed, we need to calculate the slope of the line connecting the points at 2 seconds and a nearby point, which is 4 seconds.
- The change in position is 12 meters - 12 meters = 0 meters (since the position remains constant), and the change in time is 4 seconds - 2 seconds = 2 seconds.
- As a result, the instantaneous speed at 2 seconds is 0 meters per 2 seconds = **0 m/s**.
2. **Average Speed over the Entire Trip**:
- The average speed over the entire trip can be calculated by dividing the total distance traveled by the total time taken.
- The object travels from 0 meters to 12 meters (12 meters) and then back to 0 meters (12 meters total distance). The total time taken is 12 seconds (0 to 12 seconds).
- Therefore, the average speed over the entire trip is 12 meters / 12 seconds = **1 m/s**.
In summary, the instantaneous speed at 2 seconds is **0 m/s** since the position remains constant, and the average speed over the entire trip is **1 m/s** based on the information provided by the position-time graph.
The probable question maybe:
A graph titled Position versus time for with horizontal axis time (seconds) and vertical axis position (meters). The line runs in 3 straight segments from 0 seconds 0 meters to 4 seconds 12 meters to 6 seconds 12 meters to 12 seconds 0 meters.
Use the graph to determine the instantaneous speed at 2 seconds.
