A. It is the strongest force possible.
Explanation:
The force exerted on a charged particle moving in a region with a magnetic field is given by the following equation:
where
q is the magnitude of the charge
v is the velocity of the particle
B is the strength of the magnetic field
is the angle between the direction of the velocity and of the field
From the equation, we notice that:
- The force is maximum when the particle is moving perpendicular to the magnetic field, therefore when and
- The force is zero when the particle is moving parallel (or anti-parallel) to the magnetic field, therefore when and
Based on these observation, we can immediately conclude that the only correct option among the given choices is
A. It is the strongest force possible.

Cerebrospinal fluid or Hydrocephalus
The average velocity or displacement of a particle for the first time interval is <u>Δs / Δt = 6 cm/s.</u>
Solution:
As we know that displacement is calculated in centimeters and the unit of time is second.
The average velocity for the first interval [1,2] is given
Δs / Δt = s (t2) - s (t) / t2 - t1
Δs / Δt = 2sin2 π + 3cos 2 π - ( 2sin π + 3cos π ) / 2 - 1
Δs / Δt = 2(0) + 3(1) - 2(0) - 3 (-1) / 1
Δs / Δt = 6 cm/s
Thus the average velocity or displacement of a particle for the first time interval is Δs / Δt = 6 cm/s

The complete question is:
The displacement of a particle moving back and forth along a line is given by the following equation s(t) = 2sin π t + 3cos π t. Estimate the instantaneous velocity of the particle when t = 1
<em>N</em> = 52.0 N
Explanation:
Given:
The net force is given by
Solving for <em>N</em>, we get
The acceleration of the ball would decrease when the same amount of force is applied.
<u />
<u>Given the following data:</u>
- Acceleration = 5
To determine the new acceleration of the ball when the same amount of force is applied, we would apply Newton's Second Law of Motion:
Mathematically, Newton's Second Law of Motion is given by this formula;
Substituting the given parameters into the formula, we have;
Acceleration = 3.57
Therefore, the acceleration of the ball would decrease when the same amount of force is applied.
