Roxanne is an expert at blowing bubbles with bubble gum. She discovered that her bubbles were bigger if she stood facing the Sun when she blew them. At lunch she told her three best friends about her discovery and after school they all tried it. No one else was able to blow bigger bubbles when they faced toward the Sun. Which of the following would be best for Roxanne to do next? A. She should prove she is right by blowing bubbles while her friends are watching.
B. She should give them each bigger pieces of bubble gum and try it one more time.
C. She should think about what else she is doing that might have made the bubbles bigger.
D. She should ask her friends to try it again and concentrate harder when they face the Sun.

Answer:

My guess is C

NASA plans to launch a new satellite to orbit the Earth. As the satellite is launched the thrust of the hot exhaust gas is pushed through the rocket nozzle and is accelerated toward the rear of the rocket. In turn, the rocket engine is then lifted off of the ground. According to Newton's 3rd law of motion, which statement below is true of the forces involved?
A The downward force exerted by the exhaust on the engine is greater.
B The magnitude of both forces is equal to zero acting in opposite directions.
C Both forces are equal in magnitude, but opposite in direction.
D The upward force exerted by the engine on the exhaust is greater.

B. A parallel circuit has more than one path for the circuit to take.

D. Box B because it has more mass.

A. It will be an unstable system because it will not be able to recover from the disturbance.

B. 7.0 ohms

B. on.

B. false

The magnetic forces makes a maglev train to float above the tracks because of the repulsion property and similar magnetic poles.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Box A isn't stable and will fall over since it's being pulled down and if you push it if nothing is around to secure it's movements. Box B is stable and will only side if nothing is around to secure it's movements. The mass of the boxes could also affect what would happen if you pushed the box, if Box B had a heavy mass it most likely wouldn't move. If Box A had more equilibrium and a heavy mass, It would have a better chance of not falling over.
