Photons ('particles' of light) have zero rest mass.
When they move at the speed of light (the normal situation) they do have momentum due to the relativistic nature of the Universe.
If we were to hypothesize light particles with mass the development of the Universe would be entirely different.

What will happen to the value of friction force when external force acting on the body with mass m is increased from zero to F max such that there is impending motion at F max?
the applied force will increase due to increase in mass
What happen to the acceleration of the cart as you decrease the the washers in the pan?
Decreasing washers in the pan decreases mass, so acceleration should increase.
How does mass turn into infinity at the speed of light?
It doesn't - the object will never achieve the speed of light, since an infinite mass is not possible (it would require infinite energy). This only describes a tendency: as the object gets closer and closer to the speed of light, so, too, will its mass increase more and more, approaching infinity - this means there is no upper limit to the mass as the object approaches the speed of light.
Will the mass change at a very high speed compared the speed of light?
Yes. According to the extended theory of relativity, mass will increase as an objects speed increases. The closer the object's speed gets to the speed of light, the greater its mass will be and a greater force will be required to continue to accelerate it.
What was wrong with helmonts conclusion that when plants grow their increase in mass comes from water?
Increase of mass from water. Actually increase in mass is the result of increase in organic matter instead of water.
What will happen if you increase the mass of an object what will the potential energy do?
If you increase the mass of an object, the potential energy will increase.
It is said that when energy is supplied to a body at the speed of light it is used up to increase its mass. What will happen if the mass of the body is converted into energy?
First, there is no such thing as "conversion from mass to energy".Also, if something is moving exactly at the speed of light, it can only be something that has zero mass (formerly called "rest mass"). For example, it might be photons, or gravitons - particles that can ONLY move at the speed of light. If you provide energy to an object moving at any speed, you will increase its energy - and this increase in energy will also be noticeable as some kind of mass; it will be harder to accelerate the object.
What will happen to the gravitational field if the mass of an object increase?
If the mass increases then the gravitational force will also correspondily increase as gravity is directly proportional to the mass of the object
If the mass of abject increases what will happen to its acceleration if the same amount of?
it will increase.
What has to happen for an object to float?
For an object to float, it must displace an amount of fluid equal to its weight. This is known as Archimedes' principle. If the weight of the object is less than the weight of the fluid it displaces, the object will float; if the object is denser than the fluid, it will sink.
Does the size of the particle increase with the increase in mass while close to the speed of light?
No. It contracts in the direction of velocity vector.
What happens to mass as acceleration increases?
Nothing. The force increases but the mass is constant. However if it gets fast enough the mass will increase ever so slightly and get much higher near the speed of light, according to Einstein's theory of relativity. But at ordinary speeds there is insignificant change
What would happen if there was no traffic light?
there would be more accidents
What happens to the energy that light gains from a Gravity Assist when passing by a mass in space since light cannot increase in speed?
Light cannot increase its speed, but it can increase its energy. Doing so will increase its frequency, or equivalently shorten its wavelength. It will thus be blue shifted.
What are some ways mass would increase an object?
If you accelerate it close to the speed of light it's mass increases in your frame of reference.
Why the mass of the person increases in space ship?
Mass does not increase in a spaceship. Mass increases infinitesimally according to the speed of the body. This increase does not have any effect until light speed is closely approached. Which is presently impossible with our present technology.
What will happen to the value of friction force when external force acting on the body with mass m is increased from zero to F max such that there is impending motion at F max?
the applied force will increase due to increase in mass
