A diagram that shows the Earth at the center of the solar system is known as a what?1. geocentric model.
2. heliocentric model.
3. universe model.
4. Earth-moon-sun model.

Answers

The correct answer for the question that is being presented above is this one: "1. geocentric model." A diagram that shows the Earth at the center of the solar system is known as the geocentric model. It is also known as the Ptolemaic system is a superseded description of the universe, where the Earth is at the center of all the celestial bodies.

Your grandmother in Ireland sends you her favorite cookie recipe. Her instructions say to bake the cookies at190.5°C. To what Fahrenheit temperature would you set the oven to bake the cookies?

Answers

$F=(9)/(5)C+32$

$F=(9)/(5)190.5C+32$

$F=342.9+32$

$F=374.9$

$374.9F=190.5C$

Answer:

350 Degrees Fahrenheit

Explanation:

Four power transistors, each dissipating 12 W, are mounted on a thin vertical aluminum plate 22 cm 3 22 cm in size. The heat generated by the transistors is to be dissipated by both surfaces of the plate to the surrounding air at 25°C, which is blown over the plate by a fan. The entire plate can be assumed to be nearly isothermal, and the exposed surface area of the transistor can be taken to be equal to its base area. If the average convection heat transfer coefficient is 25 W/m2·K, determine the temperature of the aluminum plate. Disregard any radiation effects.

Answers

Answer:

The temperature of the Aluminium plate 44.84⁰C

Explanation:

Number of transistors = 4

Since the heat dissipated by each transistor is 12W

Total heat dissipated, Q = 4 * 12 = 48 W

Q = 48 W

Cross sectional Area of the Aluminium plate, A = 2(l * b)

l = Length of the aluminium plate = 22 cm = 0.22 m

b = width of the aluminium plate = 22 cm = 0.22 m

A =2( 0.22 * 0.22 )

A = 0.0968 m²

From the heat balance equation, Q = hAΔT

h = 25 W/m²·K

A = 0.0968 m²

ΔT = T - T(air)

T(air) = 25°C

ΔT = T - 25°C

Q = 25 * 0.0968 * ( T - 25)

Q = 2.42 (T - 25)

Substitute Q = 48 into the equation above

48 = 2.42 (T - 25)

T - 25 = 19.84

T = 25 + 19.84

T = 44.84 ⁰C

Parallel light waves hit the surface of a still lake and reflect in the same direction. Which interaction of light and matter does this illustrate?

Answers

Parallel light waves hit the surface of a still lake and reflect in the same direction and the interaction of light and matter that it illustrates is called regular reflection. Regular reflection occurs whenever the reflecting surface is very smooth. The surface of the still lake is smooth. I hope the answer helps you.

The kinetic energy of the diver is 5040 J. The speed of the diver is 12 m/s. Calculate the mass of the diver.What's the mass of the diver?

Answers

Answer:

70 kg

Explanation:

We know that,

Kinetic energy = 1/2 mv²

Where m is mass and v is velocity or speed.

Putting the required values,

5040 = 1/2 × m ( 12 × 12)
5040 × 2 = m × 144
10080 = m × 144

divide both side by 144

m = 70 kg

So the mass of the diver is 70 kg respectively.
