A circuit has a 9v battery and 2 five ohm and 1
12 ohm resistor in parallel how much current is
flowing?

What is: 9/ (1/((1/5 + 1/5+ 1/12)))=4.35a
2 - $300

As a ball is bounced up and down what type of
energy is being demonstrated?

Potential becoming kinetic and kinetic becoming
potential
2 - $400

What is the molecular motion
occurring in the metal brand
shown in the picture?

What high kinetic motion at the hot end and low
kinetic motion on the cool end
2 - $500

The bomb squad placed a 10 kg
bomb in 100 kg bomb box
which exploded but all its
energy was contained. What is
mass of the bomb box after the
explosion?

What is 110 Kg. All energy and mass was
conserved since nothing escaped the box.
3 - $100

In the photo electric effect how would one
increase the amount of energy produced from a
specific metal?

What is use a high frequency of light
3 - $200

An EM wave travels through a small opening in a
wall then goes from the air into the water The
wave experienced:

Diffraction through the wall and refraction in the
water since the medium changed.
3 - $300

A ball is thrown at a mirror with a speed of 10
m/s. What would its relative speed appear to be
from the mirror image?

What is 20 m/s the speed was doubled.
3 - $400

What is light?

A particle and a wave or a PHOTON
3 - $500

What has the greatest effect
in increasing the power of
the electromagnet in the
picture:

Make more loops or increase the thickness of
the wire.
4 - $100

Based on the graph find the
acceleration of the car.

Vf-Vi/t or 20-0/5= 4 m/s2
4 - $200

Who has the lease accleration:
 200 Kg Elephant with 10N of force
 100 Kg Lion with 20N of force
 150 Kg Water Buffalo with 16N of force.
10/200= .05m/s2 ELEPHANT
 20/100= .02m/s2
 15/150= .01m/s2



p= mv
A 200KG Sumo is running at you
with a speed of 5 m/s. How
much momentum is he
generating to splatter you?
(200)(5)= 1000 kgXm/s
4 - $400

A cheerleader uses 400N of
force to move his partner 2m in
the air in 3 s. How much power
was exerted?

w= fxd P= w/t
(fxd)/t or (400 x 2)/3 =267 W
4 - $500

Tony Parker was moving at a constant rate of
10m/s before stopping under the basket in 2
seconds. How far did he travel before stopping?
a= vf-vi/t = 0-10/2= -5 m/s2
 X (displacement) = (vi x t) + (1/2 x a x t2)
(10x2) + (.5 x -5 x 22)=30m

5 - $100

The Waterboy runs with 100J of (KE) Kinetic
energy and collides with 10 Kgxm/s units of
momentum with a stationary quarterback. What
happened to the momentum and KE after the
contact.

Momentum remains at 10 units since it is
conserved and cannot be lost, KE became 0
Joules since it changed into Potential Energy.
5 - $200

A dog chases his tail traveling a 1m circle 10
times in 20 seconds. What was his speed and
velocity?
Speed = d/t = 20/10 Speed is 2 m/s
 Velocity = 0 m/s since the dog returns to his
starting point every time meaning there is no
displacement.

5 - $300

Since hydrogen has a simple structure only a
few electron emissions are possible what does
this mean if a current is passed through
hydrogen gas tube.

Fewer Colors will appear in the tube
5 - $400

W=1/2mv2 = ½ 80 kg x (10-5)2m/s = 1000 J
5 - $500

What would the line on velocity vs time graph
look like for a ball rolling down a hill.

The line would go up at an angle at a constant
rate since it will undergo constant acceleration.
