The arrows will follow a parabolic path.

An object is considered to be moving in a projectile motion when it is propelled by gravity.

The object that is moving in a projectile motion follows a parabolic path.

When the shooters release the arrows at the certain angle, the only force acting on them is the gravitational pull. So, they will execute a projectile motion, thus moves in a parabolic path.

A gravitational launch causes an object to take a parabolic trajectory rather than a linear one. Aiming the arrows at the target directly is therefore impossible. To compensate for the pull of gravity, it must be pointed at an angle, slightly higher than the target.

The angle must be set as far away from the target as possible. The projectile therefore continues to travel the necessary horizontal distance. The angle is affected by both the space's gravitational pull and the horizontal distance.

Note that rip currents are caused by "the flow of backwash from the beach" (Option C)

A rip current is a particular type of water stream that can happen close to beaches with breaking waves. It is frequently referred to as just a rip. Unlike a river flowing out to sea, a rip is a forceful, constrained, and narrow channel of water that travels immediately away from the beach, cutting between the lines of breaking waves.

The movement of backwash from the shore is what generates rip currents. A current may drive swimmers away from the coast and out to sea when waves break on the shore and the water flows back into the ocean. The flow of backwash from the shore is what causes this, which is referred to as a rip current.

A certain lake, filled with fresh water, is 40 m deep and located at sea level. The absolute pressure (in kpa) at the bottom of the lake will be 492.1 kPa

h = depth

P1 = rho * g * h

   = 997 * 9.8 * 40 = 390824  N / \(m^{2}\) = 390.8 kPa

The critical depth for the partially filled pipe is approximately 0.689 meters.

The critical depth in an open channel flow refers to the depth at which the specific energy is minimized, resulting in critical flow conditions. In this case, the pipe can be considered as an open channel, and we can use the specific energy equation to find the critical depth.

The specific energy equation for open channel flow is given by:

\(E = y + (Q^2 / (2gA^2))\)

where E is the specific energy, y is the flow depth, Q is the flow rate, g is the acceleration due to gravity, and A is the cross-sectional area of flow.

To find the critical depth, we need to minimize the specific energy. This occurs when the derivative of the specific energy with respect to the flow depth is equal to zero:

\(dE/dy = 1 - (Q^2 / (gA^3)) = 0\)

Simplifying the equation, we can express the critical depth as:

\(y_critical = (Q^2 / (gA^3))\)

Given the diameter of the pipe, we can calculate the cross-sectional area as:

\(A = π * (d^2 / 4)\)

where d is the diameter.

Substituting the values into the equation, we have:

\(A = π * (2.40^2 / 4) = 4.52 m^2\)

Now, we can calculate the critical depth:

\(y_critical =\) \((12.75^2 / (9.81 * 4.52^3)) ≈ 0.689 m\)

Therefore, the critical depth for the partially filled pipe is approximately 0.689 meters.

In the absence of outside forces operating on the system, the momentum of the chair would be characterized as a product of its mass and velocity and would be preserved.

The individual rising up exerts an external force on the system, changing its momentum. In this case, the chair has mass and velocity due to its travel across the floor.

According to the conservation of momentum concept, a system's overall momentum stays constant until it is affected by an outside force. The chair will thus lose velocity as it rolls backward and eventually come to a stop.

Answer:

The frequency of the wave is 5 Hz

Explanation:

Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).

Frequency is the number of vibrations that occur in a unit of time. Its unit is s – 1 or hertz (Hz).

The propagation velocity is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave disturbance propagates along its displacement. Relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation: v = f * λ.

In this case:

Replacing:

50 \(\frac{m}{s}\) = f* 10 m

Solving:

\(f=\frac{50 \frac{m}{s} }{10 m}\)

If you float the ball at equilibrium in oil, the ball will have more than half of its volume submerged in the oil.

When an object floats, it moves the same volume of fluid as the object itself weighs. The displaced fluid exerts an upward buoyant force on the object, balancing its weight and allowing it to float at equilibrium.

Since oil is less dense than water, it provides less buoyant force per unit volume compared to water. To achieve equilibrium in oil, the ball would need to displace a greater volume of oil to counteract its weight. As a result, more than half of the ball's volume would need to be submerged in the oil for it to float at equilibrium.

Final potential energy (U_final) = 0.5 * k * (L - 1/4 * L)^2

First, let's calculate the potential energy stored in the spring when it is compressed to three-fourths of its original length:

Initial potential energy (U_initial) = 0.5 * k * (L - 3/4 * L)^2

The spring constant (k) is not given in the problem, so we need to determine it. We can use Hooke's Law to find the spring constant:

k = F / x

where F is the force applied to the spring and x is the displacement from the equilibrium position. Since the spring is at rest, the force is equal to the weight of the book:

F = m * g

where g is the acceleration due to gravity (approximately 9.8 m/s²).

Now, we can calculate the initial potential energy:

U_initial = 0.5 * k * (L - 3/4 * L)^2

Next, we calculate the potential energy when the spring is compressed to one-fourth of its original length:

Final potential energy (U_final) = 0.5 * k * (L - 1/4 * L)^2

According to the principle of conservation of mechanical energy, the initial potential energy is equal to the final potential energy when the book is at its maximum height. So we can equate the two expressions:

U_initial = U_final

Solve this equation to find the value of L, which represents the height above the floor from which the text was released.

and the time for which the ball strikes the floor is

t = 1.05 × 10⁻² s.

We need to find the force applied to the ball.

The formula to calculate force is given as:

F = Δp / t

Therefore, we can calculate the force applied to the ball as:

= 1.52 kg*m/s / 1.05 × 10⁻² s

= (1.52 × 10²) / (1.05 × 10⁻²) N
