Due to the gravitational pull of earth the asteroid would be pulled towards earth, so the answer is B.
Answer:
<u>true</u>
Explanation:
they both have an electrical charge
protons have a positive charge while electrons have a negative charge but both still have an electrical charge
The x component of the force is 8.4N * cos(31°) = 7.2N (2 s.f.)
1) Size of the image: 2 cm
In order to calculate the size of the image, we can use the following proportion:

where
p = 80 m is the distance of the tree from the pinhole
q = 20 cm = 0.2 m is the distance of the image from the pinhole
= 8 m is the heigth of the object
is the height of the image
By re-arranging the proportion, we find

2) Magnification: 0.0025
The magnification of a camera is given by the ratio between the size of the image and the size of the real object:

so, in this problem we have
