To minimize your time to reach your friend, you should swim to the point directly across from your current position and then run along the opposite bank.
This is because the time you would take to swim to any other point along the opposite bank would be the same (100m / 3m/s = 33.33s) but the distance you would run would be different, and thus the time running would be different.
The time taken to run along the opposite bank is 300m / 5m/s = 60s. So the total time taken to reach your friend would be 33.33s + 60s = 93.33s.
This is the fastest way to reach your friend since you are taking the shortest path which is directly across the river and running along the opposite bank.

How do you compare and contrast sound waves and electromagnetic waves?
Sound waves are mechanical waves that require a medium to travel through.
What is Electromagnetic waves?Electromagnetic waves are a form of energy that have both electric and magnetic field components. They are part of the electromagnetic spectrum and are created by the oscillation of electric and magnetic fields. These waves travel at the speed of light and can be transmitted through empty space, solid objects, and even through the human body.
They are created by vibrating objects, and the sound waves travel through the medium, such as air or water, to reach the ear. Electromagnetic waves, on the other hand, are transverse waves that do not require a medium to travel through. These waves are created by oscillating electric and magnetic fields, and they can travel through a vacuum and other materials, such as gases, liquids, and solids. They are also responsible for carrying energy from one place to another.

2. rank the objects in order of least buoyant force to most buoyant force. is there any relationship?
The buoyant force in the increasing order is:
F<A<D<B<C=E
What is buoyant force?The buoyant force is an upward directed force that acts on any object when it is submerged either partially or completely inside a static fluid.
A body is able to float on the surface of fluid because of the buoyant force acting on the object, which tends to balance the weight of the object. The strength of the buoyant force on an object depends on the mass/volume of the fluid displaced by the object. This principle is known as Archimedes' Principle. According to Archimedes' principle, the buoyant force acting on an object is equal to the weight of the fluid displaced by the object.
The weight of an object is given by the equation:
W=mg
Here,
• m is the mass of the object.
• g=9.8m/s² =9.8m/s² is the acceleration due to gravity.
In terms of the volume, V and density ρ, the above equation becomes:
W=ρVg
It can be seen from the above equation that for a constant, ρ, we have:
W∝V
Therefore, the buoyant force will be proportional to the volume, Vf , of the fluid displaced by the object. Since the volume, Vf of the displaced fluid is equal to the volume of the object submerged inside the fluid, we have:
Vf = Vo∴Fb∝Vo
Therefore, the buoyant force in the increasing order is:
F<A<D<B<C=E

3. 4. A horse runs with a velocity of 15 km/hr towards the north for 90 minutes. Determine the displacement of the horse.
Explanation:
A car travels north on the highway for 125 kilometers, then turns west for 75 kilometers, then makes a u-turn and travels south for 125 kilometers.
A. To determine the displacement of the car, you would need to calculate the final position of the car relative to its initial position. In this case, the car traveled north for 125 km, then west for 75 km, and then south for 125 km. This means the car ends up in the same place it started (125 km south of its starting point), so the displacement would be 0 km.
Anthony has 25 kilograms of sand, while Juan has 60 pounds of sand. To determine which of the two boys has the most amount of sand, we need to convert the weight of the sand from pounds to kilograms. 60 pounds is approximately 27.2 kilograms. So Juan has 27.2 kilograms of sand and Anthony has 25 kilograms of sand. Anthony has more sand.
A horse runs with a velocity of 15 km/hr towards the north for 90 minutes. To determine the displacement of the horse, you would need to calculate the distance traveled by the horse. You can use the formula: Displacement = velocity x time. In this case, the velocity is 15 km/hr and the time is 90 minutes (converted to hours). So, Displacement = 15 x (90/60) = 22.5 km towards the North.

the magnitude (in m/s2) and direction of the plane's average acceleration during this time interval is a = -9 m/s2 in westward direction.
The rate at which velocity changes is called acceleration. Acceleration typically indicates a change in speed, but not necessarily. An item that follows a circular course while maintaining a constant speed is still moving forward because the direction of its motion is shifting.
Include the appropriate variables and the specified values in your writing.
v = 0 m/s and u = 135 m/s
t = 15 s
To calculate the necessary acceleration for the given scenario, write the first law of motion.
At zero speed, v = u + at = 135 m/s + a(15 s) a = -9 m/s2.
The plane is deaccelerating in the opposite direction of motion in this case, as indicated by the negative magnitude of acceleration. As a result, the magnitude in m/ s2 is 9 m/ s2, and the average acceleration of the plane during this time period is westward.

(a) What current will flow through the bulb?
(b) If the bulb converts 20% of the energy to light, how much light energy is produced per second?
Answer:
So, 20W of light energy is produced per second.
Explanation:
a) To calculate the current flowing through the bulb, we use the formula:
I = P / V
Where P is the power in watts (100 W) and V is the voltage (220 V).
I = 100 / 220 = 0.45 A
b) To find the light energy produced per second, we use the formula:
E = P x t
Where P is the power in watts (100 W) and t is the time in seconds.
As we know only the power and not the time, we have to calculate the energy efficiency of the bulb.
Efficiency = (Energy output/ Energy input) * 100
Efficiency = (Light energy output / Total energy input) * 100
Let's assume that the bulb is on for 1 sec
Efficiency = (Light energy output / 100W) * 100
Light energy output = (Efficiency / 100) * 100W = 20W
Efficiency = 20%

When air at 1000 mb is lifted to 700 mb, it will be colder than the surrounding air.
This represents an unstable condition, as the air is not able to stay in its current state and is forced to move up and away from its original position. This creates a situation where the colder air is more dense and is more likely to sink back down towards its original position.
In an unstable condition, the air is constantly moving and shifting, making it difficult to predict what the weather conditions will be.
This condition is considered to be unstable because the air has become less dense than the air around it. As the air rises and cools, the air molecules condense and form clouds which can lead to the development of storms.

The final momentum of the volleyball is 0.5 kg · m/s .
What is the final momentum of the ball?We have to consider the Second law that was put forward by Isaac Newton. According to the law, the rate of change of the momentum would be directly proportional to the impressed force.
We would now have momentum to make use of the law as we know it to be able to obtain the final of the object. Let us bear in mind that;
Ft = p2 - p1
F = force
t = time
p2 = final momentum
p1 = initial momentum
Then we would now substitute the values from what we have in the question and have;
150 * 0.01 = p2 - (-1)
150 * 0.01 = p2 + 1
1.5 = p2 + 1
p2 = 1.5 -1
p2 = 0.5 kg · m/s
Thus the final momentum as we have done the calculation here is 0.5 kg · m/s .

1) A rectangular coil, its dimensions are 20 cms x 10 cms, it consists of 100 turns. It rotates around an axis parallel to its length in a magnetic flux of density 35 x 10 Tesla. A maximum e.m.f. of 4.4 volt was created. Calculate the speed which it rotates.
A rectangular coil, its dimensions are 20 cms x 10 cms, it consists of 100 turns. It rotates around an axis parallel to its length in a magnetic flux of density 35 x 10 Tesla. A maximum e.m.f. of 4.4 volt was created. The speed with which it rrotates is 0.252 radians/sec
How do we calculate the value for speed?The formula for calculating the speed is given by:
Speed = (e.m.f. x N) / (B x A)
Where e.m.f. = 4.4 volts, N = 100 turns, B = 35 x 10 Tesla, and A = 20 cm x 10 cm = 200 cm2
Speed = (4.4 x 100) / (35 x 10 x 200) = 0.252 radians/sec
Therefore, the correct answer is as given above. It could be calculated that the speed with which it rotates is 0.252 radians/sec.
