A person throws a balloon straight down above level ground. The balloon bounces back up into the air. Drag force is significant
love history [14]

Explanation:

   a) Balloon is being thrown down and is speeding up;

           mg > F_drag

  b) Balloon is in the air on its way down and moving with constant speed.

           F_drag =mg

  c) The Balloon is on the ground and rest instantaneously

           mg = Normal

  d) Balloon is moving slowly downward;

   e) Because, at the peak of trajectory drag force  is 0.

             Drag force = 0

A turntable reaches an angular speed of "45 rev/min" in "4.10 s" after being turned on. What is its angular acceleration?
Marina86 [1]

Answer:

1.15 rad/s²

Explanation:

given,

angular speed of turntable = 45 rpm

                       =45\times \dfrac{2\pi}{60}

                       =4.71\ rad/s

time, t = 4.10 s

initial angular speed = 0 rad/s

angular acceleration.

\alpha = \dfrac{\omega_f-\omega_0}{t}

\alpha = \dfrac{4.71-0}{4.10}

\alpha = 1.15\ rad/s^2

Hence, the angular acceleration of the turntable is 1.15 rad/s²

Why can't alpha particles penetrate deeply into solids? Alpha particles have low mass. Alpha particles have high mass. Alpha par
Juliette [100K]
Alpha particles have both high mass and low velocity, but it would be the former that determines why they can't penetrate. An alpha particle is made of two protons and two neutrons, which is quite a large mass for a particle. This large mass keeps it from penetrating too deeply into anything, since it will essentially "get stuck" when it comes too near to another atom.
So the answer, I believe, is B. Alpha particles have high mass.
