The pressure of the water on the diver is given in an expression written as:
<span>p=15+15/33d
where p is the pressure and d is the distance of the diver </span><span>below the surface.
The pressure is calculated as follows:
</span>p=15+15/33(100) = 15.00 pounds per square feet
Therefore, the correct answer is option A.
Velocity includes direction

The time of flight of the launched particle will be 2v₀ sinθ / g.
<h3>What is kinematics?</h3>
The study of motion without considering the mass and the cause of the motion.
A projectile is launched from level ground with an initial speed v₀ at an angle θ with the horizontal. If air resistance is negligible.
Then the time of flight of the launched particle will be given as,
Determine how long it requires the projectile to reach its highest point in order to calculate the flight duration. Just twice as long as the maximum altitude is the travel time.

At maximum height,
.
The time to reach maximum height is given as

The time of flight is given as,

Substituting in
, then we have
The time of flight of the launched particle will be 2v₀ sinθ / g.

Answer:
a) least mass
Explanation:
According to the Newton's first law of motion, more the mass of a body the greater is its inertia, and inertia is the tendency of a body to resist any change to its state of rest or uniform motion.
Greater is the mass of charge least is its deflection under the influence of magnetic field.
<em>This can be explained well by the mathematical equations relating the </em><em>centripetal force and the magnetic force</em><em> on a charged mass moving in a magnetic field perpendicular to the velocity:</em>

where:
m = mass of the charged particle
v = velocity of projection of the charged mass into the magnetic field
r = radius of curvature of path of charged mass under the magnetic force
q = magnitude of charge on the particle of mass 'm'
B = intensity of magnetic field normal to 'v'


i.e.
- Speed of the charge is higher when its mass is lesser and according to the Fleming's left hand rule we known that the charge continuously faces a magnetic force while moving in the field.
& also,

- Which indicates that more is the mass of charge larger is the radius of its trajectory of motion which means lesser is its deviation.
