D. Mechanical waves need to have a medium
Explanation:
the formula is given by :
F=<u>Gm'•m"/</u> r²
where F is the force pulling them towards each other
G is the universal gravitational constant
m'andm" are the masses in contact
and r is the separation between the balls
so we just need to substitute the values and find r ,the gravitational constant is 6.67x10-¹¹. r=Gm'm"/F
1. ) It's good to remember contact information such as phone number or email.
2.) Your address, so if they need to mail anything to you, they can. This is also a necessary point of information on most job applications anyway.
3.) Past job experiences and ways to contact them. This is probably one of the most important things as it shows you've worked before and are willing to talk to past employers.
May I have brainliest please? :)
As per Newton's law of inertia we can say every object will move in its state of motion either in the state of rest or will move with same constant velocity until some unbalanced external force will act upon it
so here we have to fill the space which says that stationary object can start or moving object will change its direction only in which case
so here the correct answer should be Unbalanced Force condition we will obtain such situation.
so we have
<u>Unbalance force</u> can cause a stationary object to start moving or a moving object to change its speed or direction or both.
