Answer:
The type of material of which the resistor is made.
The length of the resistor.
The thickness of the resistor.
The temperature of the conductor.
Answer:
I'm not sure how to use it using the Series, but it would be the plastic comb
Explanation:
In the winter, it's likely to be cold and the glass would absorb that energy, also making it cold. in order to be able to hold it, you would need something warm, thus making the plastic one the better option as it is less likely to absorb the cold energy
Answer:
h~=371.26m
Explanation:
when an object falls we use the equations of accelerated motion. There is only one that gives distance.
Since we have no initial velocity (started from rest) we can get rid of the (ut) term
where a we substitute g (gravitational acceleration, constant for given heights and almost 9.81m/s^2).
Answer:
1/f = 1/D' + 1/D
The magnification equation relates the ratio of the image distance and object distance to the ratio of the image height (h^i) and object height (h^o). The magnification equation is stated as follows:
M= H^i/H^o = D^i/D^o
Answer:
It is virtual and behind the mirror
Explanation:
When an image is produced by a mirror, we have the following situations:
- The image is said to be in front of the mirror if it is on the same side of the object, with respect to the mirror
- The image is said to be behind of the mirror if it is on the opposite side of the object, with respect to the mirror
Moreover:
- The image is said to be real if it is in front of the mirror
- The image is said to be virtual if it is behind the mirror
In this case, the image (located at point I) is on the opposite side of the object (located at point O), so it is virtual and behind the mirror.
