True or false velocity is the slope of the displacement vs. time graph?
It depends on whether it is a positive slope or a negative slope. If the velocity increases as time goes on, yes the particle is accelerating. If the velocity decreases as time goes on, it is decelerating.
What happens to the angular velocity of an object as it starts to decrease in size?
Because momentum is conserved, if the size or mass decreases, its inertia decreases so its angular velocity will increase
What happens to the velocity when wavelength increases?
We got the formula: speed of medium c = frequency f times wavelength lambda. f = c / lambda lambda = c / f If c increases, also f increases. c is proportional to f, if lambda stays constant. If c increases, also lambda increases. c is proportional to lambda, if fstays constant.
How does a change in force effect accelaration?
Force is directly proportional to acceleration, so acceleration changes as force changes, whether it increases, decreases, or remains constant.
Does the wavlength increase when a refraction of a wave occurs when the wave travels from one material into another?
The wavelength changes. Whether it increases or decreases depends on the index of refraction of both materials.
A small slope on a velocity vs. time graph indicates a small acceleration true or false?
It depends on whether it is a positive slope or a negative slope. If the velocity increases as time goes on, yes the particle is accelerating. If the velocity decreases as time goes on, it is decelerating.

How to know whether the velocity of a particle increases or decreases?
by analysing the direction of the forces acting on it. If the net force is acting in the opposite direction to the motion, it slows down, if it's in the same direction, it speeds up. If the net force is zero, the object continues moving at a constant velocity
The value of the determines whether the graph of an exponential function increases or decreases from left to right?
base
Does temperature increase affect resistance?
Yes. The exact effect - whether it increases or decreases - depends on the material.
What happens to the angular velocity of an object as it starts to decrease in size?
Because momentum is conserved, if the size or mass decreases, its inertia decreases so its angular velocity will increase
Find the percent from fifty-five to sixty and tell whether it increases or decreases?
55 to 60 is an increase of 9.09%
How can you determine whether ionization energy is a periodic function of atomic number?
as atomic number increases, ionization energy also decreases
When a gas expands whether its density increases or decreases?
the density decreases because the particles spread out and so less particles occupy the same amount of area meaning the substance is less dense.
What happens when m decreases but still greater than 0?
If you raise the value of "m" then the graph increases depending on whether the slope is negative or positive
