The correct answer is c

Otto is a football player and he is working on getting in shape but carbohydrates fuel the body, so this is not the best idea. Hence, option C is correct.

What is diet?

Diet, as used in nutrition, refers to the items a person frequently eats and drinks (or a group). A regulated diet, or one that fulfills the physical needs of an individual, may be used during a specific illness therapy or health condition management.

For instance, a diabetic's diet could be limited to a few foods and beverages that can assist control blood sugar levels. Diabetes patients are advised to consume a lot of fiber, non-starchy fruits, and vegetables. Because starchy foods are high in carbohydrates, eating a lot of them may raise your blood sugar levels.

According to the question, otto is working out several times a day so he needs energy which is provided by a carb diet that contains carbohydrates. So, he must take some carbs on a regular basis.

of the car?
TE 10m

Answers

The centripetal acceleration  of the car is equal to [tex]22.5 \;m/s^2[/tex].

Given the following data:

Radius, r = 10 meterSpeed, V = 15 m/s.

To determine the centripetal acceleration  of the car:

Mathematically, the centripetal acceleration of an object is given by the formula:

[tex]A_c = \frac{V^2}{r}[/tex]

Where:

[tex]A_c[/tex] is the centripetal acceleration.r is the radius of the circular track.V is the velocity of an object.

Substituting the given parameters into the formula, we have;

[tex]A_c = \frac{15^2}{10}\\\\A_c = \frac{225}{10}\\\\A_c = 22.5 \;m/s^2[/tex]

energy of a photon is ______ proportional to frequency, and _______ proportional to wavelength.

Answers

Answer:

1. directly

2. inversely

Explanation:

The relationship between the energy of a photon and its frequency is dictated by another simple equation:

E = hv = hc/λ

where E is the energy in kiloJoules per mole, h is Planck's constant with a value of 6.626 x 10-34 Joule-seconds per particle, λ is the wavelength of light λ in meters,  and c is the speed of light with a constant value of 300 million meters per second. From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and vice versa.

Energy of a photon is directly proportional to frequency, and inversely proportional to wavelength.

What is energy?

Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form

The relationship between the energy of a photon and its frequency is

E = hv = hc/λ

where E is the energy in kiloJoules per mole,

h is Planck's constant with a value of 6.626 x 10-34 Joule-seconds per particle,

λ is the wavelength of light λ in meters,  

c is the speed of light with a constant value of 300 million meters per second.

From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength.

Assume the elevator has upward acceleration a, and consider the stack that has two boxes of mass M. What is the magnitude of the force exerted on the top box by the bottom box

Answers

Answer:

Explanation:

M(a+g)

The force acting on the top box by the bottom box both having a mass of m stacked in an elevator moving upward with an acceleration of a is,

m(a +g).

What is force?

Force is an external factor acting on a body to change it from the state of motion or rest. There are different types of forces such as gravitational force, nuclear force, tension force etc.

Newton's second law states that the force acting on a moving body is the product of its mass and acceleration. If the body of mass m is moving upward with an acceleration a, the force F will be equal to ma.

If the body moves downwards, then the net acceleration is the gravity g that is 9.8 m/s².

Here, both the boxes are moving upward and experience an acceleration a. The force exerted by the box at the bottom is with the acceleration g.

Thus ,the net force experienced by the box at the top by the box at the bottom is equal to F= m (a + g) .

Answers

Ok so you convert minutes to hours and multiply by 74 which gives 32.1km and the same goes for the 40 min which is 40/60 hours
and multiply that by 31 which is 21.7 km and for the 14 min it’s 14/60 times 27 which is 6.3 adding up all the kilometers gives you 32.1+21.7+6.3 and then you add all the minutes 26+40+14+12 which is 92 divide that by 60 and you get 1.53 hours and the km are 60.1, 60.1/1.53 gives us 39.3km/h.

Placing a soccer ball on the top shelf increases the Gravitational potential energy

what is Gravitational potential energy ?

In a gravitational field the energy possessed by an object due to a change in its position called as gravitational potential energy, it is an energy that is related to gravitational force or to gravity.

When a mass of the body  (m) is moved from infinity to a point inside the gravitational influence of a source mass (M) in absence of acceleration and the amount of work done in displacing it into the source field is stored in the form of potential energy denoted with the symbol Ug.

when external force is applied, then the  position of the body changes potential energy is equal to the amount of work done on the body by the forces.

The gravitational influence on a body at infinity is zero, then the  potential energy is zero, PE = m*g*h where m = mass, g = 9.81m/s², acceleration of gravity, h = height
