how much energy is needed to heat 2kg of cooking oil with a specific heat capacity of 2000j/kg°c from 20°c to 120°c
Answers
Answer:
400kj
Explanation:
h =mass × specific heat capacity × change in temperature
= 2×2000×[120-20]
=2×2000×100
=400000j
=400kj
400kj of energy is needed.
Energy:Energy, which is observable in the execution of labor as well as in the form of heat and light, is the quantitative quality that is transferred to a body or to a physical system in physics. Energy can be transformed in form but cannot be created or destroyed, according to the rule of conservation of energy. The joule, which is the energy supplied to an object by the labor of moving it a distance of one meter against a force of one newton, is the unit of measurement for energy in the International System of Units (SI).Cooking oil:Cooking oil is a liquid fat made of plants, animals, or synthetic materials that are used in baking, frying, and other cooking processes. It may also be referred to as edible oil because it is used in cold food preparation and flavoring, including salad dressings and bread dips.At room temperature, cooking oil is normally a liquid, although some saturated-fat oils, such as coconut oil, palm oil, and palm kernel oil, are solids.Solution -Formula - h = mass × specific heat capacity × change in temperature
So,
\(2\) × \(2000\) × \([120-20]\)
\(2\) × \(2000\) × \(100\)
\(=400000j\\=400kj\)
Therefore, 400kj of energy is needed.

Temperatures
Wind speed/direction
Precipitation
Answers
The winds aloft chart for the Great Lakes (Michigan is fine) region displays the wind direction and speed at several altitudes. At 3000 feet, the wind speed is approximately 17 knots.
At 12,000 feet, the wind speed is about 44 knots. The wind speed at FL350 is approximately 67 knots.Surface friction has an effect on the winds close to the ground, slowing them down due to the frictional force exerted on the ground by air molecules. The winds shift direction with altitude, veering to the right of the direction of travel in the northern hemisphere. The approximate location of the Jetstream can be obtained by examining the wind/temperature plot chart. The fastest wind speed at FL360 appears to be approximately 145 knots, traveling towards the northeast. Flight to the east or southeast would benefit from this wind speed.Seasonally, winds aloft change depending on the position of the jet stream, which moves towards the poles during the summer months and towards the equator during the winter months.
The current surface analysis chart (Prog chart) shows the major frontal activity passing through the Midwest states. Precipitation is what leads the frontal passage in general, with both temperature and wind speed/direction changing from behind to ahead of the front.

explain why spraying and asphalt road with water will make it easier to walk across and bare feet on a hot sunny day
Answers
Spraying an asphalt road with water will make it easier to walk across and bare feet on a hot sunny day because it has a high specific heat capacity.
What is Specific heat capacity?This is referred to as the amount of heat which is required to raise the temperature of the unit mass of a given substance by a given amount.
Water as a compound has a very high specific heat capacity which means that it needs a high amount of heat for the temperature to change. This therefore means that when the water is sprayed on the surface, the road doesn't become too hot and can be walked on with the barefoot which makes it the correct reason.

If the area of A1=0.005m^2 and the area A2=0.10m^2, external input force F1=100N. Calculate the output force F2.
Answers
Answer:
\(F_2 = 2000N\)
Explanation:
Given
\(A_1 = 0.005m^2\)
\(A_2 = 0.010m^2\)
\(F_1 = 100N\)
Required
Calculate \(F_2\)
The solution to this question is Pascal's principle of pressure
Pressure is calculated using:
\(Pressure (P) = \frac{Force(F)}{Area(A)}\)
For the input force:
\(P_1 = \frac{F_1}{A_1}\)
Substitute values for F1 and A1
\(P_1 = \frac{100}{0.005}\)
\(P_1 = 20000\)
For the input force:
\(P_2 = \frac{F_2}{A_2}\)
Substitute value for A2
\(P_2 = \frac{F_2}{0.10}\)
The pressure in the system is constant.
So:
\(P_1 = P_2 = 20000\)
Substitute 20000 for P2
\(20000 = \frac{F_2}{0.10}\)
Make F2 the subject
\(F_2 = 20000 * 0.10\)
\(F_2 = 2000N\)
Hence, the output force is 2000N

if a sine wave of 440 hertz is being played through a guitar amp, and two microphones are being used to record this guitar amp, what is the difference in distance (in inches) between the microphones if the recorded sine waves are 170 degrees out of phase? assume the speed of sound in air is 1,126 ft/s.
Answers
The difference in distance between the microphones is approximately 8.69 inches.
We can use the formula:
Δx = (λ/360) * 170 * (v/f)
where Δx is the distance difference between the two microphones, λ is the wavelength of the sound wave, v is the speed of sound, and f is the frequency of the sound wave.
First, we need to find the wavelength of the sound wave:
λ = v/f = 1126 ft/s / 440 Hz = 2.559 ft
Converting the result to inches, we get:
λ = 2.559 ft * 12 in/ft = 30.71 in
Substituting into the original formula, we get:
Δx = (λ/360) * 170 * (v/f)
Δx = (30.71 in / 360) * 170 * (1126 ft/s / 440 Hz)
Δx = 8.69 in

The radius of curvature of a rear- view mirror in a car is 4m. If a truck is behind the
car, located 5m from the rear-view mirror of the car. Calculate the size of the image
relative to the size of the truck and also find the position and nature of the image formed
Answers
The image of the truck formed by the rear-view mirror is smaller and virtual, located in front of the mirror.
To calculate the size of the image relative to the size of the truck formed by the rear-view mirror, we can use the mirror equation:1/f = 1/u + 1/v,
where f is the focal length (radius of curvature) of the mirror, u is the object distance, and v is the image distance.
Given that the radius of curvature of the mirror is 4m and the truck is located 5m from the mirror, we can determine the object distance:
u = -5m (since the object is behind the mirror and its distance is negative)
Substituting these values into the mirror equation, we get:
1/4 = 1/(-5) + 1/v
Simplifying the equation:
1/v = 1/4 + 1/5
1/v = (5 + 4) / (4 * 5)
1/v = 9/20
v = 20/9
Now, we can calculate the size of the image relative to the size of the truck using the magnification formula:
magnification = -v/u
Substituting the values:
magnification = -(20/9) / (-5)
magnification = 4/9
Therefore, the size of the image relative to the size of the truck is 4/9. This means the image formed by the rear-view mirror is smaller than the actual truck.
As for the position and nature of the image, since the image distance (v) is positive, the image is formed on the same side of the mirror as the object. In this case, it means the image is formed in front of the rear-view mirror. The positive image distance also indicates that the image is virtual.
