The stone will strike the ground after approximately 8 seconds.
To solve this problem, we can use the equation of motion for a freely falling object:
h = v₀t - 1/2gt²

Where h is the height of the object at time t, v₀ is the initial velocity, g is the acceleration due to gravity (32.2 feet per second squared), and t is the time elapsed.

At the highest point of its trajectory, the stone's velocity will be zero. Therefore, we can use the given initial velocity to find the time it takes for the stone to reach its maximum height:

v₀ = 96 feet per second
h = 265 feet
t₁ = v₀/g = 96/32.2 = 2.98 seconds

After this, the stone will fall back to the ground. We can use the same equation of motion to find the time it takes to reach the ground:

h = 0 (ground level)
v₀ = -96 feet per second (negative because it is in the opposite direction of the initial velocity)
t₂ = sqrt(2h/g) = sqrt(2(265)/32.2) = 4.01 seconds

The total time it takes for the stone to strike the ground is the sum of the time it takes to reach the maximum height and the time it takes to fall back to the ground:

t = t₁ + t₂ = 2.98 + 4.01 = 6.99 seconds

Rounding to the nearest whole number, we get that the stone will strike the ground after approximately 8 seconds.

The sign of the vertical position is positive, velocity is negative, and acceleration during the downward part of the trajectory of the ball is negative.

option B is the correct answer.

During a projectile motion, the vertical velocity of a projectile decreases as the projectile moves upwards and eventually become zero as the object reaches the maximum height.

As the object begins move downwards, the vertical velocity of the projectile increases and eventually becomes maximum before the object hits the ground.

During the horizontal motion of a projectile, the horizontal velocity of the projectile does not change. That is the initial horizontal velocity of the projectile equals the final horizontal velocity of the projectile.

(b) The end A of the solenoid behaves like a north pole

Explanation:

According to Lenz's law we have that the induced emf direction in the solenoid due to the rapid introduction of the bar magnet will be such that the electric current induced will have a resultant magnet field that will  oppose to the movement of the north pole of the bar magnet that resulted in the magnetic field

Therefore, the opposing magnetic pole to the north pole of a magnet is a north pole and the solenoid end A will act like the north pole.

The highest flow rate that this filter can process is 2,160 gpm.

The maximum filtration rate allowed for a filter depends on the filter's size and the permissible flow rate per unit area of the filter. In this case, the filter has an area of 18 feet x 20 feet = 360 square feet.

The surface area of the filter is:

18 feet x 20 feet = 360 square feet

To determine the maximum flow rate, we need to multiply the surface area by the maximum filtration rate allowed:

360 square feet x 6.0 gpm/ft2 = 2,160 gallons per minute (gpm)

Therefore, the highest flow rate that this filter can process is 2,160 gpm.

The resistance of the gold wire cannot be determined with the information given. The resistance of a wire depends on several factors, including its length, cross-sectional area, and resistivity.

While we know the resistance of the aluminum wire, we do not know any of these other factors for the gold wire. Additionally, the resistivity of gold is different from that of aluminum, so even if we did know all the other factors, we could not simply use the same resistance value for the gold wire.

Therefore, to determine the resistance of the gold wire, we would need more information, such as its length and cross-sectional area.

It is easier to stop a lightly loaded truck than a heavier one with equal speed due to the concept of inertia and the relationship between mass and momentum.

Inertia is the tendency of an object to resist changes in its state of motion. The greater the mass of an object, the greater its inertia. When a truck is in motion, it possesses kinetic energy and momentum.

When we apply brakes to stop a moving truck, we need to counteract its momentum. Momentum is the product of an object's mass and velocity and is a measure of how difficult it is to change the object's motion. The momentum of an object is directly proportional to its mass.

In the case of a heavily loaded truck, it has a greater mass compared to a lightly loaded truck. Consequently, it possesses a greater amount of momentum at the same speed. The greater momentum requires a greater force to stop the truck.

When braking is applied, the force of friction between the truck's tires and the road surface acts as the decelerating force. The force of friction is the same for both the lightly loaded and heavily loaded truck, assuming all other factors remain constant. However, the heavier truck has a greater resistance to changes in motion due to its higher mass and momentum. As a result, it requires a stronger and longer-lasting braking force to overcome its inertia and bring it to a stop.

In summary, the greater mass and momentum of a heavily loaded truck make it more challenging to stop compared to a lightly loaded truck with the same speed. The heavier truck's increased inertia necessitates a greater force to counteract its momentum and bring it to a halt.

The correct option is B: The tension on the aluminum wire is approximately 65 N.

To find the tension on the aluminum wire, we can use the formula for the speed of transverse waves in a string:

v = √(T/μ)

where:

v = speed of transverse waves

T = tension in the wire

μ = linear mass density (mass per unit length) = density * area

First, let's calculate the area of the aluminum wire:

Given diameter = 4.6 mm

Radius = diameter/2 = 4.6 mm / 2 = 2.3 mm = 2.3 x \(10^(^-^3^)\) m

Area = π * \(r^2\)

      = π * (2.3 x 10⁽⁻³⁾)²

      = π * (5.29 x 10⁽⁻⁶⁾)

      ≈ 1.658 x 10⁽⁻⁵⁾ m²

Now, let's calculate the linear mass density (μ):

Density of aluminum = 2700 kg/m³

Linear mass density (μ) = density * area

                       = 2700 kg/m³ * 1.658 x 10⁽⁻⁵⁾ m²

                       ≈ 0.0447 kg/m

Now, we can rearrange the formula for the speed of transverse waves to solve for tension (T):

T = μ * v²

Given v = 38 m/s and μ = 0.0447 kg/m, we can calculate T:

T = 0.0447 kg/m * (38 m/s)²

 ≈ 63.9906 N

Rounding to the nearest whole number, the tension on the wire is approximately 64 N.

Therefore, the closest option from the given choices is: b) 65 N

Answer:

The gravitational force on the elevator = 4500N

Explanation:

The given parameters are;

The force applied by the elevator, F  = 4500 N

The acceleration of the elevator = Not accelerating

From Newton's third law of motion, the action of the cable force is equal to the reaction of the gravitational force on the elevator which is the weight, W and motion of the elevator as follows;

F = W + Mass of elevator × Acceleration of elevator

∴ F = W + Mass of elevator × 0 = W

F = 4500 N = W

The net force on the elevator is F - W = 0

The gravitational force on the elevator = W = 4500N.

The gravitational force on the elevator, if the elevator is NOT accelerating is 4500 N.

Given data:

The magnitude of force on the elevator is, F = 4500 N.

From Newton's third law of motion, the action of the cable force is equal to the reaction of the gravitational force on the elevator which is the weight, W and motion of the elevator as follows,

F = W + ma

Here, a is the acceleration of the elevator. Since, the elevator is not accelerating. Then, a = 0 .

The weight of the elevator is due to the gravitational force. So, we need to obtain the weight as gravitational force.

Solving as,

\(F = W+ma\\\\F=W +(m \times 0)\\\\4500=W\\\\W = 4500 \;\rm N\)

Thus, we can conclude that the gravitational force on the elevator, if the elevator is NOT accelerating is 4500 N.
