The Physics test

10 Questions - Developed by: - Developed on: 2019-04-19 - 1,829 taken - 3 people like it

An advanced quiz that stretches even the brightest minds thin, this test is to test how much you really know about physics.

No sugarcoating, no fluff. Just science

1

Why does a thermistor's electrical resistance decrease as it gets hotter?

Thermistor's particles oscillate with greater KE
As it gets hotter, the thermistor emits more infrared
Thermistor's electrons move to conduction band

2

What is the 'period of equillibrium'?

The time where fusion pressure=gravity in a star
The time taken for one wave passage
The equilibrium of a circuit's resistance and current

3

Why can't Gamma rays be used to image bones like X rays?

Gamma rays have too low wavelength to be used
X rays have better transmission
Gamma rays transmit through bone

4

What allows a positive nucleus to not disperse from repulsive forces?

Quark induced strong force
Gamma energy
Protons are too heavy to be repelled

5

What is archimedes' principle?

Buoyancy=mass of fluid displaced
The brownian motion of fluid pulls objects down
Upthrust=weight of fluid displaced

6

What is the generator effect?

Using electric fields to absorb electrons in objects
The intrinsic generation of current by moving wire in magnetic field
Inducing a voltage on a conductor by moving it in a B field

7

What is a beta particle?

An electron
Pure kinetic energy
A fast moving neutron

8

What does the area of a force-extension graph of a spring represent?

Elastic momentum
Energy Transfer
Potential force

9

Why is cold fusion impossible?

Nuclei need high KE to overcome electrostatic forces
Nuclei need more electrons in their conduction band, away from the nucleus
Neutrons turn into cold glue

10

What is newton's second law of motion?

F=ma
Inertia is mass
Every action force has an equal and opposite reaction force

This is not physics this is a general knowledge quiz. did u not feel ashamed to call this is a physics test when it contains 0 math?
