<span>The last main subatomic particle to be discovered was the
antihelium-4. It was discovered on 2011
and it is measured and produces through the STAR detector. The Antihelium-4 was discovered accidentally
when an experiment was conducted. It is
also the first particle that was discovered by the means of experiment.</span>
Answer:
B = 6.18 10⁻⁶ T
the magnetic field is in the negative direction of the y axis
Explanation:
The magnetic force is given by
F = q v x B
as in the exercise indicate that the velocities perpendicular to the magnetic field,
F = q v B
Newton's second law is
F = m a
let's substitute
q v B = m a
B = m a / q v
let's calculate
B = 9.1 10⁻³¹ 2.50 10¹³ / (1.6 10⁻¹⁹ 2.30 10⁷)
B = 6.18 10⁻⁶ T
The direction of the field can be obtained with the right hand rule, where the thumb points in the direction of the velocity, the fingers extended in the direction of the magnetic field and the palm in the direction of the force for a positive charge.
In the exercise indicate that the velocity is the z axis
the acceleration and therefore the force in the x axis
therefore the magnetic field is in the negative direction of the y axis
B. The sound of the engine will get louder and the pitch higher.
Answer:
Potential
Explanation:
The water in the bathtub has more potential energy than that in the tea cup because it has a greater number of water molecules.
Mass is a parameter that is very instrumental in determining potential energy.
The potential energy of a body is the energy due to the position of that body.
Potential energy = mass x acceleration due gravity x height
Mass is the amount of matter in a substance. Water in the tub will have more mass and contain a greater number of water molecules there in.
Since potential energy is directly proportional to mass, then, it will have a greater amount of potential energy.
