Answers
Answer:
v = 46.67 km/h
Explanation:
We will use the following formula throughout this numerical:
s = vt
where,
s = distance covered
v = speed
t = time taken
FOR FIRST 30 km:
s = 30 km
v = 30 km/h
t = t₃₀ = ?
Therefore,
30 km = (30 km/h)(t₃₀)
t₃₀ = (30 km)/(30 km/h)
t₃₀ = 1 h
FOR TOTAL 100 km:
s = 100 km
v = 40 km/h (Average Speed)
t = total time = ?
Therefore,
100 km = (40 km/h)(t)
t = (100 km)/(40 km/h)
t = 2.5 h
FOR LAST 70 km:
s = 70 km
t₇₀ = t - t₃₀ = 2.5 h - 1 h = 1.5 h
v = v₇₀ = ?
Therefore,
70 km = v(1.5 h)
v = 70 km/1.5 h
v = 46.67 km/h

Answers
Each solution tested has its advantages and disadvantages. The most effective solution depends on the situation and the amount of oil that needs to be removed from the water.
The three solutions tested to remove oil from water are scooping the oil with a spoon, absorbing the oil with a paper towel, and using soap to break up the oil. Each solution has its advantages and disadvantages. Scooping the oil with a spoon is an effective solution to remove a significant amount of oil quickly. However, it is not a practical solution for removing a large amount of oil. The disadvantage is that it spreads the oil around the surface of the water and leaves some oil in the water. Absorbing the oil with a paper towel can effectively remove a lot of oil. The advantage is that it removes some oil from the water, leaving it relatively clean. However, it also picks up a lot of water and can't get all of the oil. Using soap to break up the oil is a good solution that removes all of the oil from the water. The advantage is that it removes all of the oil from the water, leaving it clean. However, the disadvantage is that it disperses the oil on the surface of the water, making it harder to remove from the sides of the bowl. In conclusion, each solution tested has its advantages and disadvantages. The most effective solution depends on the situation and the amount of oil that needs to be removed from the water.

A car goes 15 miles at 45mph, then goes another 15 miles at 30mph. a. How long does the trip take? b. What is the average speed for the whole trip?
Answers
The trip takes a total of 1.5 hours and has an average speed of 40 mph.
To calculate the time taken for each leg of the trip, we can use the formula time = distance/speed.
For the first leg of the trip, the car travels 15 miles at a speed of 45 mph. Using the formula, we find that the time taken for this leg is 15/45 = 0.33 hours.
For the second leg of the trip, the car travels another 15 miles but at a speed of 30 mph. Using the formula, we find that the time taken for this leg is 15/30 = 0.5 hours.
To find the total time for the trip, we add the times for each leg: 0.33 hours + 0.5 hours = 0.83 hours.
To calculate the average speed for the entire trip, we use the formula average speed = total distance/total time. The total distance traveled is 15 miles + 15 miles = 30 miles. The total time taken is 0.83 hours. Plugging these values into the formula, we find that the average speed for the trip is 30/0.83 = 36.14 mph.
Therefore, the trip takes a total of 1.5 hours and has an average speed of 40 mph.

Two resistors, R1 = 25.0 ohms and
R2 = 64.0 ohms, are connected in
parallel. R1 has a 0.200 A current
flowing through it. What is the current
through R2?
Domomhor resistors in norollal
Answers
Answer:
The current through R2 is 0.078125 amperes.
Explanation:
Ohm's law is the relationship between electrical conductors and their resistance, which establishes that the current that passes through the conductors is proportional to the voltage applied to them.
Ohm's Law relates the magnitudes of voltage, resistance, and intensity as follows:
V=I*R
where V is the electric potential in volts, I is the current in amperes, and R is the resistance in ohms.
R1 has a 0.200 amperes current flowing through it and a resistante of 25 ohms.
So:
V=0.200 amperes* 25 ohms
Solving:
V=5 volts
Now, for resistance R2 you know the value of the voltage (5 volts) and the value of its resistance R2 = 64 ohms. So:
5 volts= I* 64 ohms
Solving:
\(I=\frac{5 volts}{64 ohms}\)
I= 0.078125 amperes
The current through R2 is 0.078125 amperes.
Answer:
the current through R₂ is 0.078 A
Explanation:
Given;
resistance of the first resistor, r₁ = 25 ohms
resistance of the second resistor, r₂ = 64 ohms
current through the first resistor, I₁ = 0.2 A
The voltage passing through each resistor is constant since they are connected parallel to each other.
V = I₁R₁ = I₂R₂
\(I_2 = \frac{I_1R_1}{R_2} \\\\I_2 = \frac{0.2 \times 25}{64} \\\\I_2 = 0.078 \ A\)
Therefore, the current through R₂ is 0.078 A

How many kJ of heat are needed to raise the temperature of 491 g of water from 73°C to 100°C in preparing a cup of coffee?
Answers
Around 55.37 kJ of warm are required to raise the temperature of 491 g of water from 73°C to 100°C in planning a glass of coffee.
To calculate the sum of warm required to raise the temperature of the water, we utilize the equation:
q = mcΔT
where q is the sum of warm,
m is the mass of water,
c is the particular warm capacity of water,
and ΔT is the alteration in temperature.
The particular warm capacity of water is 4.184 J/g°C,
which suggests it takes 4.184 joules of vitality to raise the temperature of 1 gram of water by 1 degree Celsius.
Changing over the given mass of water from grams to kilograms:
491 g = 0.491 kg
The alter in temperature is:
ΔT = 100°C - 73°C = 27°C .........(1)
Substituting these values into the equation:
q = (0.491 kg) x (4.184 J/g°C) x (27°C)
q = 55.37 kJ
Subsequently, around 55.37 kJ of warm are required to raise the temperature of 491 g of water from 73°C to 100°C in planning a glass of coffee.

If a fish looks upward at 45 degrees with respect to the water's surface, it will see:
a. the sky and possibly some hills. b. another fish in the pond. c. the bottom of the pond. d. only the waters surface
Answers
If a fish looks upward at 45 degrees with respect to the water's surface, it will see option a, the sky and possibly some hills.
When a fish looks upward at a 45-degree angle with respect to the water's surface, it will see the sky and possibly some hills. This is because light rays refract when they pass from one medium to another with different optical densities.
As light travels from air to water, it slows down, and its path bends towards the normal, which is perpendicular to the water's surface. This bending of light is called refraction. When the fish looks upwards, it sees the light that has been refracted by the water, and this light carries information about the sky and the surrounding landscape.
However, the amount of refraction depends on the angle of incidence of the light ray, so the fish will not see the entire sky but only a portion of it. At a 45-degree angle, the fish will see a wider view of the sky and possibly some hills, depending on the surrounding topography. Therefore, the fish will not see the bottom of the pond, which is below its line of sight.

Answers
Lenses are thicker in the center, rather than on their edges because C) bend light rays so they meet at a point on the other side of the lens.
How do they bend light rays?Lenses have the purpose of altering the direction of light rays by means of refraction when they traverse through them. The bending of the lens results in the deviation of light rays.
The center of a convex lens, which has a thicker center and thinner edges, has a greater curvature compared to the edges. As a result of this occurrence, the angles of the light beams are more tightly curved, causing them to meet at a specific location on the opposite end of the lens referred to as the focal point.
By nature, lenses are able to concentrate light and produce visual representations, causing their size to increase in the central region.

Answers
To increase the force between two point charges by a factor of 8, you must change the distance between them by a factor of √2.
According to Coulomb's Law, the force (F) between two point charges is directly proportional to the product of the charges (q1 and q2) and inversely proportional to the square of the distance (d) between them:
F = k * (q1 * q2) / d², where k is Coulomb's constant.
To increase the force by a factor of 8, we have:
8F = k * (q1 * q2) / (d')², where d' is the new distance.
Dividing the first equation by the second equation, we get :
8 = (d²) / (d')²
Taking the square root of both sides:
√8 = d / d'
Therefore, the factor by which you must change the distance is:
d' = d / √8 = d / √(2^3) = d / (2*2) = d / (2 * √2)
Summary: To increase the force between two point charges by a factor of 8, you must change the distance between them by a factor of √2.

Answers
The impact of sediments and nutrients brought by storm water runoff on a lake or pond ecosystem is called eutrophication which increases the growth of aquatic life.
What is eutrophication?A pond starts out with mostly water, very few nutrients, and very little aquatic life. The pond accumulates nutrients over time. This process of enrichment is known as eutrophication.
Nutrient addition promotes the growth of aquatic life. These organisms exist, grow, and die. Their remains decay in the pond, and the nutrients used to grow them are released back into the pond's water to continue the cycle.
However, there will be an accumulation of decay-resistant material, and the pond will fill up. It will eventually become a bog and resemble dry land. The process of returning to dry land can take a decade or centuries.
