<u>According </u><u>to </u><u>Newton,</u><u> </u><u>the </u><u>bodies </u><u>in </u><u>the </u><u>universe </u><u>attract </u><u>each </u><u>other.</u><u> </u><u>This </u><u>force </u><u>if </u><u>attraction</u><u> </u><u>is </u><u>called </u><u>force </u><u>of </u><u>gravitation</u><u>.</u><u> </u> For example, the earth attracts the moon and the moon attracts the earth too. Similarly, the earth attracts the Jupiter and the Jupiter attracts the Earth.
The effect of force of attraction of a big body on a small body can be observed but that of a small body on a big one cannot be observed. The sun is so large that even the sum of the masses of all its planets and the satellites is only about 0.0015th part of mass of the sun. Due to the gravitational force between the sun and the earth, the earth keeps on moving around the sun. Similarly, the gravitational force between the satellites and planets makes the satellites to revolve around the planets. So, The gravitational force is responsible for the existence of solar system. The effect of gravitation can be experienced more on liquid than solid. Hence, we see tides in the sea and ocean due to the force of gravitation of the moon and the sun on the earth when they lie on the same straight line.

Answer:
Electromagnetic wave
Explanation:
Snow days are announced on the by phoning the parents and guardians and also the news about a snow day can be broadcast on the television or radio airwaves or on the internet which are forms of electromagnetic wave transmission
An electromagnetic wave are oscillations of electric and magnetic fields which form electric and magnetic field vibrations
The direction of the oscillating electric and magnetic fields is perpendicular to the direction of propagation of the electromagnetic wave.

Dear Brother,
You are about to enter secondary school! I believe you will do great, but here are a few things you should watch out for. Number 1, toxic relationships, this would be someone that takes advantage of you, forces you to do things you don't want to, and tries to make you feel bad when you don't listen to or do what they want you too. I think the best way to solve this is to confront the person about how they make you feel. If they don't listen or you don't feel comfortable confronting them then the next best thing is to cut them out of your life. People who try to guilt trip you for stupid things and make you feel bad are not good people to be around!
Number 2, Peer Pressure, this would be when a group or single person tries to pressure you into doing something that you're not comfortable with. They could try to pressure you too, bully/prank someone, skip school, try something you know is bad like smoking or drugs. The best thing to do when you're under peer pressure is to just say no, as hard as it can be. You could also just walk away, even make up an excuse to leave. If someone keeps pressuring you to do something it is best to talk with someone you trust about it.
Number 3, Procrastination, this one can be the worst sometimes! Procrastination can be your worst enemy! But it's best to just try to power threw it. Try to remind your self that the more you wait the more stressed you'll be when it comes time to, turn in that assignment, finish that paper, or clean your room. If you really need help, try to set reminders or ask someone to push you when you get lazy.
Those are just a few tips to help you threw secondary school! I know you'll make the right choices and work hard!
Your best regards,

Sorry this is long, but I was bored and I'm also a bit of an overachiever. I hope this helped!
0.77 m/s2 directed 35° south of west
net force = (-17,-12)
net force = mass * acceleration
(-17,-12) = 27 * (x-acceleration,y-acceleration)
(x-acceleration,y-acceleration) = (-17/27,-12/27) = (-0.629629629..., -0.444...)
angle of acceleration = tan^-1 (-0.444.../-0.629629...) = 35.21759 degrees below negative x-axis.
magnitude of acceleration = sqrt((-0.629629...)^2 + (-0.444...)^2) = 0.77069 (5dp)
Explanation:
The given data is as follows.
Electric potential energy () = ?
Formula to calculate electric potential energy is as follows.
=
=
Thus, we can conclude that the electric potential energy of the pair of charges when the second charge is at point b is .
