Bottle rocket: when the bottle is launching, how can newton's laws affect...

...how can newton laws affect a bottle that is launching up into the sky? how newton 1st, 2nd and 3rd law affect the physics, pressure and motion of bottle rocket that is traveling in the air? 10 PO

Calculate the speed of a satellite moving in a stable circular orbit about the Earth at a height of 5000 km.

Let R = Earth radius = 6.37e6 m r = distance of satellite above earth surface = 5e6 m accel of satellite = gravitational pull orv^2/(R + r) = 9.8*[6.37e6/(5e6+6.37e6)]^2 = 3.08 m/sec^2 v =5914 m/san

Why are energy levels in an atom quantized

Please do not answer telling WHAT would happen if they were not quantized. the why i am asking is much deeper and has to do with the actual why....may be its the same why as in why is energy and mass

Why doesn't water just fly off of the Earth

I mean, if gravity pulls water DOWN, then wouldnt it just all be pushed off the Earth someplace near the South Pole, South America, and Australia?-Because God blessed the water after He created the Ea

Sound is produced by ______ which must travel through matter

:)-longitudinal waves :)-Sound is produced by waves of energy traveling through a medium (like air water rock metal etc but not a Vacuum), Specifically longitudinal waves, ifyou need to think of how y

What would happen if a hydraulic system had a leak and lost some of its fluid

a. The pressure would remain the same, but less force would be transferred. b. The pressure would be reduced, and less force would be transferred. c. The pressure would increase, and more force would

Uniform-Motion Acceleration

A purse at radius 1.60 m and a wallet at radius 3.20 m travel in uniform circular motion on the floor of a merry-go-round as the ride turns. They are on the same radial line. At one instant, the accel

Section 8.3 The Equations of Rotational Kinematics

A wind turbine is initially spinning at a constant angular speed. As the winds strength gradually increases, the turbine experiences a constant angular acceleration of 0.190 rad/s2. After making 2860

How to find the distance, no air resistance

For a projectile (unknown density/surface are) I have found the initial speed, distance and flight time, how do I find the horizontal distance air resistance didnt exist? I cant just use a drag formul

Grade 11 Physics help

A 613kg mass is placed on a forklift that can generate 950W of power. What is the constant speed of the forklift while lifting this load? Its simple enough, I just cant figure it out. Thanks guys!-(6

0.173t+0.152t^2-0.035t^3=V(t) t is time in seconds

during a regular respiratory cycle, the volume of air in liters in the human lungs can be described by the function: 0.173t+0.152t^2-0.035t^3=V(t) where t is time in seconds. about how long does a re

I need some help with physics questions.

The potential difference between a storm cloud and the ground is 5.0 x 10^7 volts. During a lightning flash, 3.0 coulombs of charge are transferred to the ground. A. How much energy is transferred to

Help with friction and no friction physics problem

a small block slides along a track fro one level to a higher level by moving through a intermediate valley.the track is frictionless until the block reaches the higher level.there a friciontial force

Help on solving for stress in physic problem

I thought I got how to do stress, yet I was wrong. My answers were totally off the right answers. Could someone please show me clearly step by step how to get the right answers provided for my future

A projectile is launched vertically from the surface of the Moon with an initial speed of 1100 m/s

At what altitude is the projectiles speed one-half its initial value? I cant seem to get the right answer...please help-Mass of the Moon: M = 7.35x10^22 kg Radius of the Moon: R = 1.738x10^6 m We wi
