c is what you want from a fire ?
Answer:
Explanation:
Since the surface is frictionless therefore there will be no friction force on block but there will be weight of block which we can divide in to two components i.e. mgcosθ &mgsinθ which is perpendicular and parallel to the surface respectively.
In response to mgcosθ ramp will apply a normal force to the block which will be of equal magnitude to that of mgcosθ.
Therefore Ramp will apply a Force of mgcosθ on block where m is the mass of block.
Answer:
B
Explanation:
It's because the line keeps going straight meaning it has a constant velocity from beginning to end.
If you mean with the visible eye, then its radiation. we cant see radiation.
