The protons will possess a force pointing to the right.
The force is called Laurentz Force, which is measured by: F = qvB
Here, q is positive for proton, v and B are cross product determined by right hand rule.
Answer:

Explanation:
Since, Alex is at rest. Therefore, the speed measured by him will be the absolute speed of car P. Therefore, taking easterly direction as positive:
And the absolute velocity of Barbara's Car is given as:
Now, for the velocity of Car p with respect to the velocity of Barbara's Car can be given s follows:


Answer:
Protein molecules
Explanation:
Ribosomes are the cell organelles that are responsible for the synthesis of protein in the cell. Proteins are the fundamental building blocks and help in repair and damage of cell in the body.
Ribosome is a complex which is made up of protein and RNA. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.
Answer:
The objects have opposite charges.
Explanation:
The object when released are moving towards each other simply because they attract each other.
- According to coulombs law of charges, like charges repel and will move away from one another.
- Unlike charges attracts and moves towards one another
- Since the objects are coming towards each other, they are of opposite charges.
When the ball reaches its original position, it will have the same speed (but would be traveling in the opposite direction). So the average speed is

regardless of how long the ball was in the air.
