The acceleration measures the change in velocity.
Since the acceleration is in the direction opposite to the speed, the velocity eastwards will decrease : its magnitude will first decrease, then it reach 0 m/s, then finally it will increase again.
Answer:
The correct option is D
Explanation:
In the course of the experiment, two key phrases/variables defined the experiment done,
i) the release height of the steel ball (independent variable)
ii) the distance the ball travels from the ramp before falling to the ground (dependent variable)
The only option that contains and relates this two variables as carried out during the course of the experiment is option D.
Negative beta decay. So probably 4.
Answer:
The magnitude of magnetic field is 1.19 T and its direction magnetic is in negative x direction.
Explanation:
Given that,
Speed of a proton, 
(due +x direction)
When it moves in the positive y direction it experiences a force of, 
(due positive z direction)
We need to find the magnitude and direction of the magnetic field. The magnetic force is given by :
For direction :
So, the magnitude of magnetic field is 1.19 T and its direction magnetic is in negative x direction.
