Answer:
speed and temperature
Explanation:
Two major factors, mass and distance, affect the strength of gravitational force on an object. You witness the first factor in everyday life - more massive objects are heavier weight the force with which an object near the Earth or another celestial body is attracted toward the center of the body by gravity. An object's weight depends on its mass (the amount of matter it consists of) and the strength of the gravitational pull.
Adaptation is when a living thing changes its behavior to survive in its surroundings.
Answer: hello options related to your question is missing attached below is the missing part of your question
answer: No charge of the length of the bonds expected because the rod did not touch the charge source ( option A )
Explanation:
When the Charge is first, Furthest away and second and closest to the source charge. <em>The spring like bonds can be said to have No charge of the length of the bonds expected because the rod did not touch the charge source </em><em>when Furthest away the bond with charge will be less effective </em>
If force is applied at 30 degree with the horizontal
then first we will find the components of force in two directions
![F_x = 20 cos20](https://tex.z-dn.net/?f=F_x%20%3D%2020%20cos20)
![F_y = 20 sin30](https://tex.z-dn.net/?f=F_y%20%3D%2020%20sin30)
now we can find normal force by balancing the forces in Y direction
![F_n + Fy = mg](https://tex.z-dn.net/?f=F_n%20%2B%20Fy%20%3D%20mg)
![F_n + 20 sin30 = 3*10](https://tex.z-dn.net/?f=F_n%20%2B%2020%20sin30%20%3D%203%2A10)
![F_n + 10 = 30](https://tex.z-dn.net/?f=F_n%20%2B%2010%20%3D%2030)
![F_n = 20 N](https://tex.z-dn.net/?f=F_n%20%3D%2020%20N)
now since block is moving with constant speed
so here forces along horizontal plane will be balanced also
![F_x = F_f](https://tex.z-dn.net/?f=F_x%20%3D%20F_f)
![F_f = 20 cos30](https://tex.z-dn.net/?f=F_f%20%3D%2020%20cos30)
![F_f = 17.3 N](https://tex.z-dn.net/?f=F_f%20%3D%2017.3%20N)
Now the weight of the box is defined as
![W = mg](https://tex.z-dn.net/?f=W%20%3D%20mg)
now plug in all values
![W = 3*10 = 30 N](https://tex.z-dn.net/?f=W%20%3D%203%2A10%20%3D%2030%20N)
