Answer:
Max height= 36000 meters
Total Time = 120 seconds
Explanation:
0 = U - at
U = at
U= 20*60
U= 1200 m/s
MAX altitude would be
(U²Sin²tita)/2g
Max height= 1200² *( SIN90)²/(2*20)
Time of FLIGHT
2 * 1200/20
2400/20
120 sec

<u>Velocidad Angular</u>
Un objeto en rotación con movimiento circular uniforme describe ángulos iguales en tiempos iguales.
La velocidad angular ω es una magnitud que mide el ángulo θ que gira una partícula en cierto tiempo t, según la fórmula:
La velocidad angular suele medirse en radianes/segundo, revoluciones/minuto, grados/segundo, etc.
Si la rotación es uniforme, el valor de la velocidad angular es constante.
La rueda del problema a resolver se desplaza θ=15 rad en t=0.2 s, así que su velocidad angular es:

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!
The answer would be E, 1800. Why? bc if you're going 30 meters per second and trying to figure out how far you would go in a minute, you would multiply 30 x 60 bc there's 60 seconds in a minute. Giving you 1800 meters. hope this helped, have an amazing day :)<span />
Question
Which particles act together to make atoms behave as solids
Answer:
Electrons. Mutually repel elections of other atoms when they get close
Explanation:
A demonstration of the behavior of particles as solids, liquids and gases. Crystals, on the other hand, aren't at all haphazard. Particles are held together by forces of attraction. Protons (+) and Electrons (-) Which subatomic particles act together to make atoms behave as a solids because they are found buzzing around the nucleus.
