You have 8.66 kilometres to bike before you turn north and arrive at your friend's house The Pythagorean theorem allows us to calculate the following distance from your starting point to your friend's street:

\(d = √[(10.0 km)^2 - (6.0 km)^2] = 8.66 km\)

This is the length of a right triangle's hypotenuse, with the horizontal leg being 6.0 km (the distance to your friend's street in the north) and the vertical leg being the remaining distance to ride before making a northward turn. To determine the length of the vertical leg, we can apply trigonometry:

\(opposite/hypotenuse = sinsin = 8.66 kilometres of vertical legsin = horizontal leg / d(vertical leg / d) = sin1(6.0 km / 8.66 km) = sin (1θ = 37.13°\)

You must therefore cycle a distance equal to:

\(d sin  = 8.66 km sin 37.13° = 5.35 km vertical leg\)

The distance you must cycle in total Adding the distance to the turn and the distance from the turn to your friend's street will get you to your friend's house.

Distance total: 5.35 km plus 6.05 km equals 11.35 km

However, keep in mind that this distance is greater than the 10.0 km straight distance between your starting place and your friend's house, so if you want to reduce the amount of bicycling you do, you might want to think about finding an alternative route that completely avoids the hill.

Explanation:

The purpose of striking the ball in a volleyball game:

From the serve you could state that you need to place the ball in motion.

When returning a shot of, you normally want to change the direction of the ball's motion.

During a dropshot, you purposely want to slow down the ball's motion.

The correct answer must be all of the above.

Therefore, the period of the system is 2.513 s and the amplitude of the motion is 1.591 m.

1. In order to calculate how much you will weigh at Big Bear lake, we need to take into account the effect of gravity. The force of gravity depends on the mass of the two objects involved and the distance between them. The mass of the Earth is much larger than our own mass, so we can assume that it does not change significantly. However, the distance between us and the center of the Earth does change as we move higher up.

Using the formula for the force of gravity (F = G * m1 * m2 / r^2), where G is the gravitational constant (6.6743 × 10^-11 N*m^2/kg^2), m1 is the mass of the Earth, m2 is our own mass, and r is the distance between us and the center of the Earth, we can calculate the force of gravity acting on us at each location.
At the beach near San Diego, the force of gravity acting on us is F1 = G * m1 * m2 / r1^2 = (6.6743 × 10^-11) * (5.97 × 10^24) * (58) / (6,371,000)^2 = 570.09 N.
At Big Bear lake, the force of gravity acting on us is F2 = G * m1 * m2 / r2^2 = (6.6743 × 10^-11) * (5.97 × 10^24) * (58) / (6,373,000)^2 = 567.60 N.
Therefore, our weight at Big Bear lake is approximately 567.60 N, which is slightly less than our weight at the beach near San Diego.
2. The period of an oscillating spring-mass system is given by the formula T = 2π * √(m/k), where T is the period, m is the mass of the object attached to the spring, and k is the spring constant.
In this case, m = 0.20 kg and k = 0.50 N/m, so we can calculate the period as T = 2π * √(0.20/0.50) = 2.513 s.
The amplitude of the motion is the maximum displacement from the equilibrium position. We can find this value by using the formula Umax = A * ω, where Umax is the maximum speed achieved by the mass, A is the amplitude of the motion, and ω is the angular frequency (which is equal to 2π/T).
Rearranging this formula, we get A = Umax / ω = Umax / (2π/T) = Umax * T / (2π) = 2.0 * 2.513 / (2π) = 1.591 m.
Therefore, the period of the system is 2.513 s and the amplitude of the motion is 1.591 m.

the oil drum traveled a distance of approximately 1.56 meters.

To find the distance that the oil drum traveled, we need to use the equation for average acceleration:

d = (vf^2 - vi^2) / 2a

where d is the distance traveled, vf is the final velocity, vi is the initial velocity, and a is the acceleration.

In this case, we are given that the final velocity is 3.0 m/s, the initial velocity is 0 m/s, and the acceleration is 520 N / 180 kg = 2.89 m/s^2. Substituting these values into the equation, we get:

d = (3.0^2 - 0^2) / 2 * 2.89

= 9 / 5.78

= 1.56 m

Therefore, the oil drum traveled a distance of approximately 1.56 meters.

Answer:

no

Explanation:

ans should be correct

Answer:

Because fluid pressure increases with depth, there is more fluid pressure___outside__ of a submerged object than on the _inside___

Explanation:

As the object is submerged means that it is under water and not on the surface. It tells that water pressure exerting on the object from the outside is higher than inside which is why the object is submerged.

In the other case, the object will not remain submerged if its internal pressure is high, it will float on water.

A stationary receiver will detect the same change in frequency from a jet moving away at 600 m/s. Option C is correct answer.

The change in frequency observed by a receiver is determined by the relative velocity between the source of the signal (the jet) and the receiver. The frequency shift is known as the Doppler effect. In this scenario, the jet is moving directly away from the receiver.

The change in frequency observed by the stationary receiver will be the same regardless of the speed of the jet. The velocity of the receiver or the direction of motion does not affect the frequency shift in this case. Therefore, options A, B, and D, which involve receivers moving in different directions or at different speeds, are not relevant.

The stationary receiver will detect the same change in frequency as the jet moves away at 600 m/s because the relative velocity between the jet and the receiver remains the same. This is due to the fact that the Doppler effect depends solely on the relative motion between the source and the receiver, regardless of the receiver's motion or velocity.

The composite figure is a combination of a rectangular pyramid and a rectangular prism, hence its volume is 140in³.

A rectangular prism is simply a three dimensional solid shape with six faces that are rectangles.

Volume of a rectangular prism is expressed as;

V = w × h × l

Where l is length, h is height and w is width

A rectangular pyramid is simply a three-dimentional object with a rectangular shaped base and triangular shaped faces that correspond to each side of the base.

The volume of rectangular pyramid is expressed as;

V = (1/3) × l × w × h

Where l is the base length, w is the base width and h is the height of the pyramid.

From the diagram below;

First we calculate the volume of a rectangular prism.

V = w × h × l

V = 3in × 4in × 7in

V = 84in³

Hence, the volume of the rectangular prism is 84in³.

Next, we calculate the volume of rectangular pyramid.

V = (1/3) × l × w × h

V = (1/3) × 7in × 3in × 8in

V = (1/3) × 168in³

V = 56in³

Hence, the volume of the rectangular pyramid is 56in³.

Volume of the composite figure = Volume of prism + Volume of pyramid

Volume of the composite figure = 84in³ + 56in³

Volume of the composite figure = 140in³

Therefore, the composite figure is a combination of a rectangular pyramid and rectangular prism, hence its volume is 140in³.

When a torque is applied to a circular shaft, you can observe the following:

1. The circular shaft will experience twisting or rotational deformation, which means the angle of twist will change along the length of the shaft.
2. Shear stress will be induced in the material of the shaft, causing internal resistance against the applied torque.
3. The amount of twist or angular deformation is directly proportional to the applied torque and the length of the shaft, and inversely proportional to the shaft's polar moment of inertia and material's modulus of rigidity.

In summary, when a torque is applied to a circular shaft, you can observe twisting, shear stress, and a relationship between the applied torque, length, polar moment of inertia, and modulus of rigidity.

A food web represents the interrelationships between different organisms in an ecosystem, showing how energy and nutrients flow through various feeding interactions.

Based on the information provided, here's a simplified food web for a habitat threatened by developers removing a significant portion of grasses:

Grasses (primary producers): Grasses form the base of the food web and are an essential food source for many organisms.

Mice: Mice feed on grasses as a primary food source. They play a role as primary consumers in the food web.

Rabbits: Rabbits also rely on grasses as a primary food source. They are herbivores and act as primary consumers similar to mice.

Predators of Mice and Rabbits: Various predators depend on mice and rabbits as a food source. These may include:

a. Hawks: Hawks are birds of prey that feed on small mammals like mice and rabbits. They occupy a higher trophic level in the food web as secondary consumers.

b. Snakes: Some snake species, such as rat snakes or garter snakes, may consume mice and rabbits. They are also secondary consumers in the food web.

c. Foxes: Foxes are omnivorous predators that include small mammals, including mice and rabbits, in their diet. They act as secondary consumers.

d. Coyotes: Coyotes are another predator that may consume mice and rabbits. They are tertiary consumers, as they are higher up in the food chain.

e. Other predators: Depending on the specific habitat and location, other predators like owls, bobcats, or larger carnivores may also be part of the ecosystem and feed on mice and rabbits.

It's important to note that the removal of three-fourths of the grasses in the area would have significant implications for the entire food web. With a reduced grass population, the availability of food for mice and rabbits would decrease, potentially leading to population declines or changes in their distribution. This, in turn, can affect the predators that rely on these prey species, potentially causing ripple effects throughout the ecosystem.

The equation for the path of a comet that follows a hyperbolic trajectory around the sun can be derived based on certain conditions. Assuming that the closest distance of the comet to the sun is 2 × 10⁹ miles and the path before and after approaching the solar system is at a right angle, we can determine the equation for the comet's path.

A hyperbolic path can be described by the equation:

r(θ) = a / (1 + e * cos(θ))

Where: r is the distance from the focus (the sun) to the comet at a given angle θ, a is a constant that represents the semi-major axis of the hyperbola, e is the eccentricity of the hyperbola.

In this case, since the comet's path approaches the sun at a closest distance of 2 × 10⁹ miles, we can set this value as the value of a. The eccentricity (e) can be determined based on the right angle condition.

The equation for the path of the comet would then be: r(θ) = 2 × 10⁹ / (1 + e * cos(θ))

By determining the value of e and plugging it into the equation, we can obtain the specific equation for the path of the comet.
