1. When a SMALL EGG is dropped onto the piece of 1-inch foam, from which height did the egg break entirely? Select all that apply.
a. When dropped from 1 meter
b. When dropped from 5 meters
c. When dropped from 10 meters
d. Nonsense! the small egg never broke when dropped onto 1-inch foam

2. When a small egg is dropped onto the piece of 1-inch foam, from which height did the egg fracture but not break? select all that apply
a. When dropped from 1 meter
b. When dropped from 5 meters
c. When dropped from 10 meters
d. Nonsense! the small egg never broke when dropped onto 1-inch foam

3. When a LARGE EGG is dropped from a height of 10 meters, upon which landing surface did the egg break entirely? select all that apply.
a. When landing on the hard floor
b. When landing on the 1-inch piece of foam
c. When landing in the box filled with foam pieces
d. Nonsense! the large egg never broke when dropped onto any of the landing surfaces from a height of 10 meters

Background: This interactive involves observing the results of dropping an egg onto a surface. The size of the egg, the height from which it is dropped, and the characteristics of the landing surface can be varied. The effect of variation upon the safety of the egg will be examined. The interactive is based on the impulse-momentum change theorem. The question s target a Interactive ability to reason scientifically.

A ball, dropped onto a hard floor from a height of 2 meters, bounces to a height of 1.8 meters, 90% of the initial height. Each subsequent bounce is 90% the height of the previous one. Find the total distance the ball travels up and down (i.e. after the first collision with the ground it has traveled 2 meters down and 1.8 meters up, giving a total distance of 3.8 meters).

the max voltage produced from a magnetic being dropped through a wire with a relationship on the height the magnet is dropped from.
I am trying to the max voltage produced from a magnetic being dropped through a wire with a relationship on the height the magnet is dropped from. I know that emf=-V= N(partial derivative of magnetic flux). But I am not sure how to relate this to the height the magnet is dropped through a solenoid (wire coil). It would be amazing if anyone could help me with this formula. I tried finding the velocity with Ki, Ko and Ui, and...

A block of mass 4kg is dropped from a height of 2 meters on Earth. If that block is taken to a different planet, where the acceleration due to gravity is 1/4 as strong as it is on Earth, how high should the block be dropped so that it hits the ground with the same final velocity as on Earth? (Hint: you do not need to use gravitational force for this) Express your answer to a maximum of 2 significant...
