Your answer should be thermal energy I hope this helps
Answer:
2.7x10⁻⁸ N/m²
Explanation:
Since the piece of cardboard absorbs totally the light, the radiation pressure can be found using the following equation:
<u>Where:</u>
: is the radiation pressure
I: is the intensity of the light = 8.1 W/m²
c: is the speed of light = 3.00x10⁸ m/s
Hence, the radiation pressure is:
Therefore, the radiation pressure that is produced on the cardboard by the light is 2.7x10⁻⁸ N/m².
I hope it helps you!
Answer:input current= 282mA
Input voltage= 183V
Explanation:
A step up transformer increases the voltage by increasing the number of turns. The number of turns in the secondary coil is usually larger than the number of coils in the primary coil. The formulas for comparing ratio of turns to current and voltage in primary and secondary coils are shown in the image attached. The full solution can a!so be found in the image attached.
Answer:
Explanation:
As we know that ball travels horizontal distance of 24.7 m with uniform speed 49.4 m/s
so we will have
now in the same time ball is turned by angle
now we know that
now the tangential speed of a point at equator is given as
Answer:
Explanation:
<u>Thales Theorem
</u>
It applies when a line is drawn parallel to one side of a triangle and it intersects the other two sides. The theorem states that line divides the two sides in the same ratio or proportion.
We have drawn the triangle that describes the situation stated in the question, where we want to know the value of CD, knowing the values of BE, BA, and CA. The red line BE is parallel to the line CD, so the Tales theorem must stand meaning that the sides AC and AB are proportionally divided at the same ratio as CD and BA, thus
We can solve for CD (the height of the flagpole)
