which action will give you more momentum toward the north: throwing one shoe southward at 10 m/s or two shoes southward at 5 m/s?

Answers

Throwing one shoe southward at 10 m/s will give you more momentum toward the north.

Momentum is defined as the product of an object's mass and its velocity. The momentum of an object can be determined using the equation:

Momentum = mass × velocity

In this case, both scenarios involve throwing shoes southward, which means the velocity is directed to the south. The key difference is the magnitude of the velocity.

When throwing one shoe southward at 10 m/s, the velocity is higher compared to throwing two shoes southward at 5 m/s. Since momentum depends on velocity, the higher velocity of the single shoe results in a greater momentum.

The mass of the shoes does not play a role in determining which action gives more momentum toward the north since the mass is the same in both scenarios. Therefore, throwing one shoe southward at 10 m/s will give you more momentum toward the north compared to throwing two shoes southward at 5 m/s.

A projectile of mass 0.2 kg and an initial velocity of 50 m/s collides with the end of a blade attached to a turbine. The rotational inertia of the turbine is 12.5 kg⋅m2 . Assume the loss of energy of the projectile in the collision is completely transferred to the blades, causing them to spin. If the final rebound velocity of the projectile after hitting a turbine blade is −25 m/s , which of the following is most nearly the rotational velocity of the turbine after the collision?

Answers

Answer:

5.5 rad/sec

Explanation:

Answer:

5.47 rad/s

Explanation:

We can solve this problem using the principle of conservation of energy and angular momentum.

First, let's find the initial kinetic energy of the projectile:

K1 = (1/2) * m * v1^2

= (1/2) * 0.2 kg * (50 m/s)^2

= 250 J

where v1 is the initial velocity of the projectile.

Next, let's find the final kinetic energy of the projectile:

K2 = (1/2) * m * v2^2

= (1/2) * 0.2 kg * (-25 m/s)^2

= 67.5 J

where v2 is the final velocity of the projectile after the collision.

The loss of energy in the collision is:

ΔK = K1 - K2

= 187.5 J

This energy is transferred to the blades, causing them to spin. Let's assume that all of this energy is converted to rotational kinetic energy of the turbine.

The final rotational kinetic energy of the turbine is:

K_rot = (1/2) * I * ω^2

where I is the moment of inertia of the turbine and ω is the final rotational velocity of the turbine.

Using the conservation of energy, we can equate the loss of kinetic energy in the collision to the gain in rotational kinetic energy of the turbine:

ΔK = K_rot

187.5 J = (1/2) * 12.5 kg m^2 * ω^2

ω^2 = (2 * 187.5 J) / (12.5 kg m^2)

ω^2 = 30

ω = 5.47 rad/s

Therefore, the rotational velocity of the turbine after the collision is 5.47 rad/s.

how much force must be exerted to accelerate a 240 n weight to 5.7 m/s2

Answers

To accelerate a 240 N weight to 5.7 m/s^2, a force of 1,368 N must be exerted.

The force required to accelerate an object can be calculated using Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). In this case, the weight of the object can be considered as its mass, since weight is the force exerted by gravity on an object. Therefore, the mass (m) is 240 N (weight) divided by the acceleration due to gravity (9.8 m/s^2), which equals approximately 24.49 kg. To find the force (F) required to accelerate the object to 5.7 m/s^2, multiply the mass by the acceleration: 24.49 kg x 5.7 m/s^2 = 139.413 N, or approximately 1,368 N. Thus, a force of 1,368 N must be exerted to achieve the desired acceleration.

A block (5 kg) is pulled by a 50 N at an angle of 30◦tothe ground. The block experiences a 4,2 N frictional force and moves 2,60 m. The block starts from rest. Use the work-energy principle to calculate the speed of the block after the 2,60 m.

Please explain/name all formulas used.

Answers

The speed of the block after the 2,60 m is determined as 6.38 m/s.

What is the work done on the block?

The work done on the block is calculated by applying the principle of Newton's second law of motion to determine the net work done on the block as shown below.

W = F(net)d

where;

F(net) is the net forced is the distance

F(net) = Fcosθ - Ff

the lowest-intensity sound that is still audible has an intensity of approximately iear=10−12w/m2. consider a jet that flies at an altitude of 6500 m .

Answers

The altitude of the jet is important in determining the intensity of the sound that it produces. The intensity of the sound decreases as the distance from the source increases.

In this case, the sound wave has to travel a distance of 6500 meters from the jet to the listener on the ground. Assuming that the jet is producing a sound wave with an intensity of 100 W/m^2, the sound wave will experience a decrease in intensity as it travels from the source to the listener. The intensity of the sound wave will decrease as the square of the distance from the source. Therefore, the intensity of the sound wave at a distance of 6500 meters from the source will be:
I = (100 W/m^2) / (6500 m)^2 = 2.5 x 10^-8 W/m^2
This is much lower than the lowest-intensity sound that is still audible, which has an intensity of approximately iear=10^-12 W/m^2. Therefore, the sound produced by the jet at an altitude of 6500 meters will not be audible to the human ear.However, it is important to note that the intensity of the sound produced by the jet can vary depending on its speed and altitude. A faster jet or a jet flying at a lower altitude will produce a higher-intensity sound wave that may be audible to the human ear from the ground.

The given lens with a focal length of 200 mm can be adjusted within a range of 200.0 mm to 209.4 mm from the film. This adjustment corresponds to object distances ranging from approximately 1106.38 mm to infinity, allowing for a variety of focusing options.

To determine the range of object distances for which the lens can be adjusted, we can use the lens formula:

1/f = 1/d₀ + 1/dᵢ

Where:

f = focal length of the lens

d₀ = object distance

dᵢ = image distance

Given:

f = 200 mm

dᵢ range: 200.0 mm to 209.4 mm

To find the minimum object distance (d₀ min), we can use the maximum image distance (dᵢ max = 209.4 mm):

1/200 = 1/d₀ + 1/209.4

To solve for d₀, we rearrange the equation:

1/d₀ = 1/200 - 1/209.4

1/d₀ = (209.4 - 200)/(200 * 209.4)

1/d₀ = 9.4/(200 * 209.4)

d₀ = 1/(9.4/(200 * 209.4))

Calculating this expression, we find:

d₀ ≈ 1106.38 mm

Therefore, the lens can be adjusted for object distances ranging from approximately 1106.38 mm to infinity.

a ball spins on a 0.880-m-long string with a constant speed of 3.75 m/s. 1) calculate the acceleration of the ball. (express your answer to three significant figures.)

Answers

The acceleration of the ball spinning on a 0.880-m-long string with a constant speed of 3.75 m/s is approximately 16.1 m/s².When an object moves in a circular path with a constant speed, it experiences centripetal acceleration directed toward the center of the circle.

Acceleration is the rate at which an object's velocity changes over time. In this case, the ball is spinning on a string with a constant speed of 3.75 m/s and a length of 0.880 m. The acceleration can be determined using the formula for centripetal acceleration:

a = v² / r

where "a" is the acceleration, "v" is the velocity, and "r" is the radius or the length of the string. Plugging in the given values:

a = (3.75 m/s)² / 0.880 m

a = 14.06 m²/s² / 0.880 m

a ≈ 15.98 m²/s²

Rounding to three significant figures, the acceleration of the ball is approximately 16.1 m/s².

As a beginner bowler, Maria gets frustrated that her shots very rarely knock down any pins. Her Mom says that her arm movement looks awkward before releasing the ball. Maria feels like she needs to improve arm swing motion. How can Maria improve her bowling technique to be more successful?


Increase the weight of the ball to gain more control
Push the ball out away from her on the first step
Put more spin on the ball so that it curves prior to hitting the pins
Take fewer steps before releasing the ball to decrease her arm speed

Answers

Push the ball out away from her on the first step. Option B.

The key to consistent shots is the angle at which you pocket the ball. For right-handed bowlers, the pocket is between the 1st and 3rd pins. If you are left-handed it will be between pins 1 and 2. Keep your arms straight as you bring them back for the backswing and try to stay close to your body throughout the throw. Timing is important when releasing the ball.

A simple way to determine where the ball should exit the edge of the oil sample is simply to apply the rule of 31. Subtract 31 from the oil pattern distance. This will give you the board number where the ball ends the pattern. As a rule of thumb, right-handed bowlers place the inside of their left foot on the midpoint, and left-handed bowlers do the same with their right foot. Then stand with your other leg slightly behind you about 2 inches apart.

Answer:

Maria can improve her arm swing motion in bowling by developing a free swing, where instead of controlling the ball with her arm, the ball controls her arm. This can be achieved by putting only mild to light grip pressure on the ball and pushing it back while standing relaxed. This will let the ball down and the gravitational energy will get her arm to the apex. As soon as she reaches the apex, she’ll have to slide forward and release the ball without pulling and grabbing.

Out of the options you provided, pushing the ball out away from her on the first step seems to be a good way for Maria to improve her arm swing motion in bowling.

Which statement accurately describes viscosity?

B. A material slows or completely blocks the flow of electrons through it.
C. A material with relatively weak bonds between its particles can be shaped into a thin sheet.
D. Attractive forces between molecules at the surface cause a liquid to resist spreading out.​

Answers

The statement that accurately describes viscosity is option D: Attractive forces between molecules at the surface cause a liquid to resist spreading out. Option D

Viscosity is a measure of a fluid's resistance to flow. It quantifies how easily a fluid can be deformed or how readily it flows. In liquids, viscosity arises from the cohesive forces between molecules.

When molecules in a liquid are attracted to each other, they tend to stick together and resist movement. At the surface of the liquid, there is a greater degree of attractive forces between the molecules since they have fewer neighboring molecules to interact with.

This surface tension creates a resistance to the spreading out of the liquid and causes it to exhibit a more rounded or droplet-like shape.

The attractive forces between molecules at the surface of a liquid contribute to the cohesive forces within the liquid as a whole, resulting in a higher viscosity.

The stronger the attractive forces between the molecules, the higher the viscosity of the liquid. For example, honey has a higher viscosity compared to water because the molecules in honey have stronger attractive forces, making it flow more slowly.

Option A is not an accurate description of viscosity. Viscosity is not solely determined by the size of the molecules in a liquid but rather by the strength of the attractive forces between the molecules.

Option B describes electrical conductivity, not viscosity. It refers to a material's ability to slow down or impede the flow of electrons.

Option C describes the property of malleability, not viscosity. It refers to a material's ability to be shaped into a thin sheet without breaking.

Therefore, option D accurately describes viscosity by highlighting the role of attractive forces between molecules at the surface of a liquid in resisting the spreading out of the liquid

you see lightning and then hear thunder approximately 20 seconds later. what is the best estimate of the distance between you and the lightning strike?

Answers

The best estimate of the distance between you and the lightning strike is approximately 6860 meters.

The best estimate of the distance between you and the lightning strike can be calculated using the speed of sound in air, which is approximately 343 meters per second.

The time interval between seeing the lightning and hearing the thunder is 20 seconds, we can use the formula:

Distance = Speed × Time

Distance = 343 m/s × 20 s

Distance ≈ 6860 meters

When you see lightning, the light travels to your eyes almost instantaneously because light travels much faster than sound. However, sound travels at a much slower speed. The time interval between seeing the lightning and hearing the thunder is due to the time it takes for the sound waves to travel from the lightning source to your location.

By using the speed of sound in air, which is approximately 343 meters per second at room temperature, we can estimate the distance between you and the lightning strike. Multiplying the speed of sound by the time interval gives us the distance traveled by the sound waves.

In this case, if the time interval is 20 seconds, multiplying 343 m/s by 20 s gives us a distance of approximately 6860 meters. This means that the lightning strike occurred roughly 6860 meters away from your location. Keep in mind that this is an estimation, as the speed of sound can vary slightly depending on factors such as temperature and humidity.

Although the waves move at the same speed, the frequency that is observed is affected by any relative movement between the source and the observer. The wavelength changes along with the observed frequency. When an observer and a source are moving in the same direction, the frequency rises and the wavelength falls.
