Answer:
it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.
Explanation:
Magnetic field is along z axis while velocity is in x-z plane
so we will have
so here we can say
so we will have
so here the net force on the charge is perpendicular to its x directional velocity along - Y direction
So due to this component of motion it will move along a circle while other component of the motion will remain uniform always
So here it is combination of two parts
1) Uniform circular motion
2) Uniform motion
So we can say that it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.

Explanation:
A decrease in the ice caps causes a(n) increase in the absorption of sunlight. This cause the global temperature to rise causing more ice caps to melt. As more ice caps melt, the temperature rises. This is an example of a negative feedback loop.
Let's think of an example, water boiling to form steam.
When the water boils, it obviously does not have the same shape, and liquids and gases don't have a definite shape, so shape is not the answer.
To force a phase change, water needs energy in the form of heat, so temperature is also not the answer.
The volume is also changed, and gases take up more space than liquids, so volume is also not the answer.
So, after ruling the other three out, the one we're left with is mass, and that is the answer: mass remains constant during a phase change
