To calculate the average speed of the car, we divide the total distance traveled by the time taken. In this case, Ronald's parents drove him to his grandmother's home, which is 60 miles away, and it took them three hours to complete the journey.
Average speed (in miles per hour) is obtained by dividing the distance (in miles) by the time (in hours). In this scenario, the average speed of the car can be calculated as follows:
Average speed = Distance / Time
Average speed = 60 miles / 3 hours
Simplifying the calculation, we find:
Average speed = 20 miles per hour
Therefore, the average speed of the car was 20 miles per hour.
This means that, on average, Ronald's parents were driving at a speed of 20 miles per hour during their journey from Ronald's home to his grandmother's home. It's important to note that this is the average speed over the entire duration of the trip, and it may not reflect the specific speeds at different parts of the journey.

A submerged alligator starts swimming toward a pair of ducks dozing on a large pond, at 5.0m away from the shore. The alligator accelerates from rest, from the shore line, at a constant 0.5m/s2 . The alarmed ducks start swimming frantically away from the alligator. The equations of motions of the ducks are x1=5.0m+(1.1m/s)t and x2=5.0m-(0.4m/s)t.
Question 1: Based on this information, after how many seconds will the gator meet duck 2? Type your answer in the box provided below.
Question 2 :Build a single graph showing the motion of the three heroes of this story. Employ graph paper, if possible. Annotate the three plots (curves) to show which is which. Based on these plots, which of the ducks will the alligator catch first? Justify your answer with words and calculations. Attach your written solution.
After 2.236 seconds the alligator will meet the duck, it will take 4.5454 seconds for the alligator to catch duck 1.
Question 1: The equation of motion for the alligator can be calculated using the formula of motion which is given by,S = ut + (1/2)at²where,S = 5.0m (since alligator is starting from 5.0 m away from the shore)u = 0 (since the alligator starts from rest)t = time takena = 0.5m/s²Substituting the given values in the above equation,5.0 = 0t + (1/2)(0.5)t²2t² = 10t² = 5t = √5 = 2.236 sSo, after 2.236 seconds the alligator will meet duck.
2.Question 2: Here is the graph that shows the motion of the three characters:In this graph, the blue line represents the motion of duck 1, the green line represents the motion of duck 2, and the red line represents the motion of the alligator.Using the graph, it is clear that the alligator will catch duck 1 first. This is because the red line intersects the blue line before it intersects the green line. The time taken to catch duck 1 can be calculated as follows:x1 = 5.0m + (1.1m/s)t Substituting the value of x1 = 0 (since the alligator catches duck 1),0 = 5.0m + (1.1m/s)t-5.0m = (1.1m/s)t-4.5454 s = tSo, it will take 4.5454 seconds for the alligator to catch duck 1.

Answer:
2450 J
Explanation:
Given that,
A 50Kg girl jumps off a 5-meter-high diving board.
We need to find the kinetic energy of the girl before she hits the water. At this point the kinetic energy becomes equal to the potential energy such that,
\(K=mgh\\\\K=50\times 9.8\times 5\\\\K=2450\ J\)
So, her kinetic energy right before she hits the water is equal to 2450 J.
Suppose the sun provided somewhat less heat, this would likely cause Hadley cells to be ______ and would cause the great deserts to be located _________ the equator -A. Larger, closer to -B. Larger, farther away from -C. Smaller, closer to -D. Smaller, farther away form -E. None of the above, changing solar input would not affect hadley cells
Suppose the sun provided somewhat less heat, this would likely cause Hadley cells to be smaller and would cause the great deserts to be located closer to the equator. This corresponds to option C.
Hadley cells are large-scale atmospheric circulation patterns that transport heat from the equator towards the poles. They are driven by the difference in temperature between the equator and the poles. If the sun provided less heat, the temperature difference between the equator and the poles would decrease. This would result in a weaker temperature gradient, causing Hadley cells to become smaller.
As for the great deserts, they are primarily located in the subtropical regions where the air in the Hadley cells descends, creating high-pressure zones with low precipitation. If the Hadley cells become smaller due to reduced solar input, the descending dry air would be located closer to the equator. This would cause the great deserts to be situated nearer to the equator compared to their current locations. Hence, the correct answer is Option C.

An apple dropped from the branch of a tree hits the ground in 0.5 s. If the acceleration of the apple during its motion is 10 ms-2 in the downward direction. Calculate ----- Its speed just before it hits the ground. What is its average velocity during 0.5 s? Calculate the height of the branch of the tree from the ground?
Given that,
Time = 0.5 s
Acceleration = 10 m/s²
(I). We need to calculate the speed of apple
Using equation of motion
\(v=u+at\)
Where, v = speed
u = initial speed
a = acceleration
t = time
Put the value into the formula
\(v=0+10\times0.5\)
\(v=5\ m/s\)
(III). We need to calculate the height of the branch of the tree from the ground
Using equation of motion
\(s=ut+\dfrac{1}{2}gt^2\)
Put the value into the formula
\(s=0+\dfrac{1}{2}\times10\times(0.5)^2\)
\(s=1.25\ m\)
(II). We need to calculate the average velocity during 0.5 sec

\(v_{avg}=\dfrac{\Delta x}{\Delta t}\)
\(v_{avg}=\dfrac{x_{f}-x_{i}}{t_{f}-t_{0}}\)
Where, \(x_{f}\)= final position
\(x_{i}\) = initial position
Put the value into the formula
\(v_{avg}=\dfrac{1.25+0}{0.5}\)
\(v_{avg}=2.5\ m/s\)
Hence, (I). The speed of apple is 5 m/s.
(II). The average velocity during 0.5 sec is 2.5 m/s
(III). The height of the branch of the tree from the ground is 1.25 m.
what is the number of waves produced in a given amount of time called?
The number of waves produced in a given amount of time is called the frequency.
Frequency is a fundamental concept in wave physics and is defined as the number of waves that pass a given point per unit of time. It is typically measured in hertz (Hz), where 1 Hz represents one wave per second.
In other words, if you observe a wave passing through a fixed point and count how many complete waves pass by in one second, the count would represent the frequency of the wave.
Frequency is directly related to other wave properties such as wavelength and period. The wavelength is the distance between two consecutive points in a wave that are in phase, while the period is the time taken for one complete wave to pass a given point. These three properties (frequency, wavelength, and period) are interconnected by mathematical relationships.

In addition to 1 m = 39.37 in, the following exact conversion equivalents are
given: 1 mile = 5280 ft, 1 ft = 12 in, 1 hr = 60 min, and 1 min = 60 s. If a
particle has a velocity of 8.4 miles per hour, its velocity, in m/s, is closest to
Answer:
3.76 m/s.
Explanation:
Velocity in mile per hour (mph) = 8.4 miles per hour
Velocity in metre per second (m/s) =?
Next, we shall convert 8.4 mph to ft/h. This can be obtained as follow :
1 mph = 5280 ft/h
Therefore,
8.4 mph = 8.4 mph / 1 mph × 5280 ft/h
8.4 mph = 44352 ft/h
Next, we shall convert 44352 ft/h to in/h. This is illustrated below:
1 ft/h = 12 in/h
Therefore,
44352 ft/h = 44352 ft/h / 1 ft/h × 12 in/h
44352 ft/h = 532224 in/h
Next, we shall convert 532224 in/h to m/h. This can be obtained as follow:
39.37 in/h = 1 m/h
Therefore,
532224 in/h = 532224 in/h / 39.37 in/h × 1 m/h
532224 in/h = 13518.51664 m/h
Next, we shall convert 13518.51664 m/h to m/min. This is illustrated below:
1 m/h = 1/60 m/min
Therefore,
13518.51664 m/h = 13518.51664 m/h / 1 m/h × 1/60 m/min
13518.51664 m/h = 225.30861 m/min
Finally, we shall convert 225.30861 m/min to m/s. This is illustrated below:
1 m/min = 1/60 m/s
Therefore,
225.30861 m/min = 225.30861 m/min / 1 m/min × 1/60 m/s
225.30861 m/min = 3.76 m/s
Therefore,
8.4 miles per hour is equivalent to 3.76 m/s.
Unit conversion does not change the real value. The velocity of the particle, when converted to meters per sec, is 3.756.
What is Units conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimeter is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
In order to convert the unit of velocity, we will first convert miles to meters and then, hours to seconds.
As it is given to us,
1 mile = 5280 ft
1 ft = 12 inches
1 m = 39.37 in
Now, since 1 m = 39.37 inches, therefore
\(1\rm\ in =\dfrac{1}{39.37}\ m\)
Converting a mile to meter,
\(1\rm\ miles = 5280\ ft \times 12\ inches\times \dfrac{1}{39.38} m\\\\1\ miles = 1609.652\ m\)
Converting hours to seconds
\(1\rm\ hour = 60\ minutes \times 60\ seconds\\\\1\ hour = 3600\ seconds\)
Now, converting the velocity we will get,
\(1 \rm\ \dfrac{miles}{hour} = \dfrac{1609.652}{3600}\ \dfrac{m}{s}\\\\1 \rm\ \dfrac{miles}{hour} =0.447\ \dfrac{m}{s}\)
Now, as given to us the velocity of a particle is 8.4 miles\hour, therefore,
\(8.4 \rm\ \dfrac{miles}{hour} =8.4 \times 0.447\ \dfrac{m}{s}\\\\8.4 \rm\ \dfrac{miles}{hour} =3.756\ \dfrac{m}{s}\\\\\)
Hence, the velocity of the particle when converted to meters per sec is 3.756.

Explanation:
Balloon a is ___ charged and balloon c is ___ charged. If balloon a approaches balloon c there will be a force of blank between them
Balloon A is positively charged, and balloon C is negatively charged. If balloon A approaches balloon C, there will be an electrostatic force of attraction between them.
When two objects carry opposite charges, they exert an attractive force on each other. This force is known as the electrostatic force and follows Coulomb's law. According to Coulomb's law, the magnitude of the electrostatic force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. In this scenario, since balloon A is positively charged and balloon C is negatively charged, they have opposite charges. Therefore, the electrostatic force between them will be attractive. The magnitude of the force depends on the charges of the balloons and the distance between them. It is important to note that without specific information about the charges of the balloons and their distance, it is not possible to determine the exact magnitude of the force. To calculate the force, you would need the values of the charges and the distance between the balloons.
