A runner eats a snack with 375 Calories of nutritional energy. After her snack, she burns 3.16 x 10^6 joules while running

Answers

Answer 1

Answer:

The complete question is given below

A runner eats a snack with 375 Calories of nutritional energy. After her snack, she uses  3.16 X 106 joules while running [1 Calorie = 4184 joules).

Which of the following statements are true? Select all that apply.

A. There were 1.57 X 106 joules of energy in the snack.

B. There were 3.14 X 106 joules of energy in the snack.

C. During her run, she used 755 Calories of energy.

D. During her run, she used 189 Calories of energy.

E. The runner used more Calories while running than she consumed during her snack.

F The runner used fewer Calories while running than she consumed during her snack.

Answer: Options A, C and E are all correct options

Explanation:

From the question,

1 calorie = 4184 Joules

therefore 375 calories from the consumed snack

              = (4184 x 375) J

              = 1,569,000J

              = 1.56 x 10⁶ J (option A is correct)

While running, she expends 3.16 x 10⁶ J. We can convert this to calories to see how much calories she expended while running

Recall  4184 Joules = 1 calorie

therefore, 3.16 x 10⁶ Joules is equivalent to

                                 = (3.16 x10⁶/ 4184) calories

                                 = 755.6 calories (option C is also correct)

If she consumes 375 calories from her snack but expended 755 calories during her running exercise, therefore the runner consumed fewer calories than what she expended during her exercise, hence option E is also correct  

Answer: Options A, C and E are all correct options

What is the name and formula of an ionic compound containing the element with the
atomic number of 5 bonded to Carbonate? *
Boron Carbonide; B2(CO3)3
Boron Carbonate; B,CO,
Boron Carbide; B,CO,
Boron Carbonate; B2(CO3)3

Answers

Answer:

Boron Carbonate; B₂(CO₃)₃

Explanation:

For names, carbonide does not exist; that rules out the first option. Carbide refers to just a carbon atom, not carbon and oxygen as in the polyatomic ion carbonate. That rids us of the third option. We are left with boron carbonate with the formula BCO or boron carbonate with the formula B₂(CO₃)₃.

Recall the carbonate polyatomic ion's formula: CO₃²⁻

Thus BCO cannot be the formula.

Option 4 is your answer, Boron Carbonate; B₂(CO₃)₃.

To further check your answer, observe the oxidation states of boron and the polyatomic ion carbonate. Boron can exist in oxidation states of either 2+ or 3+, and carbonate is only 2-; in this formula, boron will exhibit a 3+ state to balance out with carbonate.

2x3+ = 6+; 3x2- = 6-

6+ + 6- = 0; balanced

2. Platinum metal has a density of 21.4 g/mL. If the block measures 3 cm, by 0.03 m, by 40 mm
how much does it weigh in milligrams?

Answers

Answer:

80mg

Explanation:

Given parameters:

Density of Platinum metal = 21.4g/mL

Dimension of the metal  = 3cm by 0.03m by 40mm

Unknown:

Weight of the metal in milligrams?

Solution:

Density is the mass per unit volume of a substance.

Mathematically;

          Density  = [tex]\frac{mass}{volume}[/tex]

Volume of the platinum metal  = l x w x h

 Let us convert the dimension of the metal to the same unit;

            3cm x 0.03m x 40mm

    convert to cm;

           100m = 1cm

           0.03m  = [tex]\frac{0.03}{100}[/tex]   = 0.0003cm

     -- 40mm;

            1mm = 0.1cm

           40mm  = 40 x 0.1  = 4cm

Volume of the metal  = 3 x 0.0003 x 4  = 0.0036cm³

1mL = 1cm³; so volume  = 0.0036mL

     Mass of the metal  = 21.4 x 0.0036  = 0.08g

       1g  = 1000mg

     0.08g  = 0.08 x 1000 = 80mg

       

Which air is driest? Air Temp 30F Dew-point 29F, Air Temp 77F Dew-point 19F, Air Temp 66F Dew-point 60F, or Air Temp 50F Dew-point 36F

Answers

Answer:

Air Temp 77F Dew-point 19F

Explanation:

Quiz

The dew point can be described as the temperature required by the air to be cooled. The driest air will have a higher dew point, therefore, at an air temperature of 66°F and a dew point of 60°F. Therefore, option (C) is correct.

What is dew point?

The dew point can be defined as the temperature at which air should be cooled to become saturated with water vapor assuming constant air pressure and water content.

Moisture capacity will decrease below the dew point. Airborne water vapor will condense to form liquid water or dew. Dew develops on the surface and occurs through contact with a cooler surface.

The dew point is called the frost point when the temperature is below the freezing point because frost is produced by deposition rather than a condensation of water.

The humidity also impacts the dew point. The dew point increases when there is higher moisture in the atmosphere.  Therefore, the higher dew point refers to less humid air or drier.

A man walks 20 meters in 10 seconds. What is the speed? *

Answers

Answer: 2m/s.

Explanation: To find a speed/rate, you use the equation d = r*t. We switch around this equation to get r = d/t. Then, we plug in the numbers. r = 20 meters/10 seconds. Thus, the rate/speed is 2 meters/second (2m/s).

A man walks 20 meters in 10 seconds the speed is 2 meters per second (m/s).

What is the speed?

Speed is something to measure the intensity of anything like any object which is moving from one place to another place and can be calculated by dividing the traveled distance by the time taken by the object.

To calculate the speed of man the given values are distance and time  20 meters in 10 seconds respectively.

                      speed = distance / time

substituting the value in equation,

               speed = 20/10  

               speed = 2 meter per second (m/s)

Therefore, a man walks 20 meters in 10 seconds the speed is 2 meters per second (m/s).

Answers

Answer:

A compound

Explanation:

The water is best classified as a compound. When a substance is broken down into elemental composition or units, they are said to be a compound.

An element is a distinct substance that cannot be split up into simpler substances. Compound are substances composed of two or more kinds of atoms  joined together in a definite grouping. The properties of compounds are distinct and different from those of the individual elements that are combined in its make - up. So, the water when broken down to elements is a compound.

What is the wavelength of radiation whose frequency is 1.56 x 10^12 Hertz?

Answers

Answer:

1.92×10¯⁴ m

Explanation:

From the question given above, the following data were obtained:

Frequency (f) = 1.56×10¹² Hz

Wavelength (λ) =?

Frequency and wavelength of a wave are related by the following equation:

v = λf

Where

'v' is the velocity of light with a constant value of 3×10⁸ m/s.

'λ' is the wavelength

'f' is the frequency.

Thus, we can obtain the wavelength of radiation by using the above formula as illustrated below:

Frequency (f) = 1.56×10¹² Hz

Velocity (v) = 3×10⁸ m/s.

Wavelength (λ) =?

v = λf

3×10⁸ = λ × 1.56×10¹²

Divide both side by 1.56×10¹²

λ = 3×10⁸ / 1.56×10¹²

λ = 1.92×10¯⁴ m

Therefore, the wavelength of the radiation is 1.92×10¯⁴ m

One s-orbital is present in each sublevel of the primary energy level. There are 2 electrons in the s-orbital in total. When compared to other primary energy levels, the electrons in this orbital, known as s electrons, have the lowest energy. Here the correct option is A.

The fixed distances from an atom's nucleus where electrons may be found are referred to as energy levels (also known as electron shells). In an atom, the small, positively charged nucleus is surrounded by smaller, negatively charged electrons.

One s-orbital, three sets of p-orbitals, and five sets of d-orbitals make up the subshell of the third main energy level. S-orbitals can store a maximum of two electrons, p-orbitals six, and d-orbitals ten. One s-orbital is present in each sublevel of the primary energy level. There are 2 electrons in the s-orbital in total.

Thus the correct option is A.

The name(s) of the subshells are s,p and d

Further explanation

Each orbital in an atom consists of 4 quantum numbers  

n is the principal quantum number.  

l is the angular momentum / azimuthal quantum number  

ml, the magnetic quantum number  

ms, the electron-spin quantum number  

Value of n: positive integer  

value of l: s = 0, p = 1, d = 2, f = 3 , ..(n-1)

ml value: between -l to + l  

ms value: +1/2 or -1/2  

n=3, then the possible value of l is a maximum of n-1 = 3-1 = 2
