<h3><u>Answer;</u></h3>
D. An image that is smaller than the object and is behind the mirror
<h3><u>Explanation;</u></h3>
- Magnification is the ratio of the height of the image to the height of the object.
- When magnification, m, is greater than 1 the image is larger than the object, and when m is less than 1 means the image is smaller than the object.
- If the magnification is positive, the image is upright compared to the object; if m is negative, the image is inverted compared to the object.
- Magnification is negative when the image is inverted, therefore a real image.
The force is opposite to the displacement
Answer:
a) when we approach sphere B with a positive car Q, it attracts negative charges from sphere A
b) phere A with a charge equal to zero
c) The charges are not distributed since there is no physical contact
Explanation:
a) Electric charges are neither created nor destroyed, they are only distributed, when we approach sphere B with a positive car Q, it attracts negative charges from sphere A in such a way that while the two spheres are close, each one has a charge + Q / 2.
b) when sphere B moves away, it no longer attracts negative charges from sphere A, so they move away from each other and neutralize themselves with positive charges, leaving sphere A with a charge equal to zero
c) The charges are not distributed since there is no physical contact between the two spheres, only a charge is induced when they are close, but when moving away each one is left with its initial charge
Answer:
Transform Boundary
Explanation:
The just slide past each other
Distance is the total length of an object's path. Displacement is the overall change in position, ie. how far an object is from its initial position.
The court is 30 m long, so a path going back and forth once is 60 m long. Going along this path 6 times totals 360 m.
The end point is the same as the starting point, so the displacement is 0 m.
