How do i solve this?

Answer:

It's all about the conduction between the pan and the cookies.

Explanation:

The cookies in the middle of the pan are not going to be cooked as much as the cookies touching both the bottom of the pan and the side of the pan due to the level of heat being given to those outside cookies. Lets try an example:

Lets say you're in a car in the middle of summer. You and your sibling sit on opposite sides of your other sibling, who is sitting in the middle seat. You and your other sibling are pressed up against the door of the car, making you heat up quicker since not only is it hot in the car, the sun is also on you. Meanwhile your other sibling isn't getting as much heat (but is still warm).

I hope this was able to help! There weren't any answers listed, so it may be the following:

- Conduction of heat

- Transfer of heat

- The pan heating up more of the cookie

- The conversion of more heat energy to the outside cookies

Good luck!

The characteristic of the displacement is a vector allows to find the results for the components of the displacement are;

The displacement is a vector quantity, therefore it has modulus and direction, see attached for a diagram.

The reference system the West - East axis coincides with the x axis and the South - North axis with the y axis.

Let's use trigonometry to find its components.

          cos 55 = [tex]\frac{y}{d}[/tex]  

          sin 55 =  [tex]\frac{x}{d}[/tex]  

          y = d cos 55

          x = d sin 55

let's calculate

         y = 310 cos 55

         x = 310 sin 55

         y = 177.8 m

          x = 253.9 m

In conclusion using the characteristics of the displacement is a vector we can find the components of the displacement are;

Answer: A. Red light is reflected

Explanation:

The four things that are dependent on the size of an electromagnetic force are magnitude of force, distance, current and the magnetic strength.

An electromagnetic force is generated from a strong electric field associated with a magnetic field. A looping current generates a magnetic field around it where, the direction of magnetic field lines are perpendicular to the electric field.

The strength of electromagnetic field definitely depends on the wire size, number of turnings, material of coli and its magnetic strength. There are both electromagnetic force of attraction and repulsion as well.

The things which are dependent on the electromagnetic force are the distance over it can act, the loop current, magnetic strength and its magnitude of magnetic field.

Image result for describe the motion of a baseball from pitch to being caught in the outfield, use as many concepts as u can

The rotation of the baseball in combination with the way the seam is spinning through the air causes the ball to move in different patterns. A few common pitches are the fastball, curve ball, slider, and the screwball. Each of these pitches has a different spin because of how the player grips the ball.

Explanation:

Answer:

When a baseball is pitched, hit and flies in the air, one or more of the physical principles formulated over 300 years ago by Sir Isaac Newton act on it. Folklore tells how the mathematician and physicist first realized the law of gravity while observing a falling apple. Had Newton watched a baseball game instead, he might have formulated all three laws of motion by the seventh-inning stretch.

Answer:

[tex]\boxed {\boxed {\sf \frac {8}{3} \ m/s^2 \ and \ not \ higher \ than \ the \ car's \ acceleration }}[/tex]

Explanation:

Acceleration is the rate of change of velocity with respect to time. It is calculated by dividing the change in velocity by the time.

[tex]a= \frac {v_f-v_i}{t}[/tex]

1. Motorist Acceleration

The motorist accelerates from an initial velocity of 0 meters per second to a final velocity of 8 meters per second in 3 seconds.

Substitute the values into the formula.

[tex]a= \frac{ 8 \ m/s - 0 \ m/s }{3 \ s}[/tex]

Solve the numerator.

[tex]a= \frac{8 \ m/s}{3 \ s}[/tex]

[tex]a= \frac{8}{3} \ m/s^2[/tex]

[tex]a \approx 2.667 \m/s^2[/tex]

2. Car Acceleration

The car accelerates from an initial velocity of 0 meters per second to a final velocity of 30 meters per second in 6 seconds.

Substitute the values into the formula.

[tex]a= \frac{ 30 \ m/s - 0 \ m/s }{6 \ s}[/tex]

Solve the numerator.

[tex]a= \frac{30 \ m/s}{6 \ s}[/tex]

[tex]a= { 5 \ m/s^2}[/tex]

The motorist's acceleration is 8/3 or approximately 2.667 meters per second squared. This is not higher than the car's acceleration of 5 meters per second squared.

Answer:

the speed of sound if the wavelength is 346 m/s

When a flute plays note with a frequency of 266 Hz and the wavelength is 1.3 m then speed of sound will be 346 m/s. Hence option C is correct.

Speed is a rate of change of distance with respect to time. i.e. v=dx÷dt. Speed can also be defined as distance over time i.e. speed= distance ÷ time it is denoted by v and its SI unit is m/s. it is a scalar quantity. Speed shows how much distance can be traveled in unit time.

To find dimension for speed is, from formula

Speed = Distance ÷ Time

Dimension for distance is [L¹] ,

Dimension for Time is [T¹],

Dividing dimension of distance by dimension of time gives,

[L¹] ÷ [T¹] = [L¹T⁻¹]

Dimension for speed is [L¹T⁻¹].

For a any wave, there is relation between speed c, wavelength λ and frequency ν which is given by,

c = λν

Given,

wavelength = 1.3 m

frequency = 266 Hz

Speed = ?

Putting all values in the equation,

Speed = 1.3 m× 266 Hz = 345.8 m/s ≅ 346 m/s

Hence option C is correct.

Now Velocity and speed have the same magnitude. Velocity being a vector quantity has a definite direction. Whereas speed is a scalar quantity,it indicates only the magnitude an doesn't define any direction.

Hence Distance = Velocity x time

Distance = 3.5 × 120 = 420 miles
