How does mass affect the speed of an object?
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.
When light passes from a low density object to a high density object its speed will?
bend towards the normal or it's speed will decrease
How does the temperature of water affect the speed at which an object sinks?
Yes. As water is heated above 4oC it expands. With this change in volume comes a change in density. Less density means less bouyant force on the object in the water.
How does density affect the floating and sinking of objects?
An object will float if it has less density than the fluid in which it is placed; if the object has more density, it will sink.
Increasing the speed of an object does not affect that object's what?
mass
does the liquids density affect the speed of melting?
If an object has more density it takes longer for the heat to reach the center so it can start melting.
Does the mass affect the speed of an object?
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.

Does the water density affect floating?
Yes, water density will affect an object's ability to float.
How does the temperature of water affect the speed at which an object sinks?
Yes. As water is heated above 4oC it expands. With this change in volume comes a change in density. Less density means less bouyant force on the object in the water.
Which of these would change the direction of an object but not affect the object's speed?
Circular motion would change the direction of an object but would not affect the object's speed.
How does density affect the transmission of sound?
The higher the density of an object, the harder it will be for the sound to be transmitted through the object.
How does the volume of an object affect object's density?
Density is mass/volume. So for a given mass as the volume increases the density will reduce.
Increasing the speed of an object does not affect that object's what?
mass
How does density affect the floating and sinking of objects?
An object will float if it has less density than the fluid in which it is placed; if the object has more density, it will sink.
The density of an object depends on what?
mass and velocitythe object's speed and mass
