The answer is C. The mass of the platinum sample is greater than the mass of the lead sample. As I explained in a previous answer, if they are the same volume, but one is heavier, then it must be more dense. In this particular example, the platinum is more dense than the lead, and therefore has more mass.
True because sometimes a breathalyzer isn't as accurate as we think and if there is multiple sources of blood they would want to rule out who's blood is who's.

Answer:
the direction of the particle is anti clockwise.
Explanation:
We know that;
- It's a positive particle
- That it's moving in a circle in a magnetic field
- We know the direction of the magnetic field
We can deduce the direction of the magnetic force because it is moving in a circle.
So the force is pointing to the centre of the circle and that's what is keeping it in that circular motion.
Since we know the direction of the magnetic field and force, we can use right hand rule to figure out the direction of the particle since the particle is positive.
Using right hand rule, the thumb which is the particle is pointing anticlockwise. So the direction of the particle is anti clockwise.
