The weight of an ice sheet can cause continental lithosphere to sink into the underlying asthenosphere due to ____.
Answer: Isostatic rebound
The weight of an ice sheet imposed on lithosphere in the continental block will cause the continent to sink in the asthenosphere due to isostatic rebound. The thickness of the ice sheet change with time as the sea level rise and the sinking of the lithosphere will continue until isostatic equilibrium is reached.
Challenge: a sound wave with a frequency of 100.0 Hz travels in water with a speed of 1,500 m/s and then travels in air with a speed of 340 m/s. Approximately how many times larger is the wavelength in water than in air?
The wavelength in water is approximately 4.41 times larger than the wavelength in air.
Explanation:In order to calculate the ratio of the wavelengths in water and in air, we need to use the formula:
ratio = speed of sound in water / speed of sound in air
Given that the speed of sound in water is 1500 m/s and the speed of sound in air is 340 m/s, we can substitute these values into the formula: ratio = 1500 m/s / 340 m/s = 4.41
Therefore, the wavelength in water is approximately 4.41 times larger than the wavelength in air.
The wavelength in water is approximately 4.4 times larger than in air.
To find the wavelength of a sound wave in a given medium, one can use the formula:
[tex]\[ \lambda = \frac{v}{f} \][/tex]
where [tex]\( \lambda \)[/tex] is the wavelength, [tex]\( v \)[/tex] is the speed of sound in the medium, and [tex]\( f \)[/tex] is the frequency of the sound wave.
Given that the frequency [tex]\( f \)[/tex] of the sound wave is 100.0 Hz, we can calculate the wavelength in water and in air using their respective speeds.
First, calculate the wavelength in water:
[tex]\[ \lambda_{\text{water}} = \frac{v_{\text{water}}}{f} = \frac{1,500 \text{ m/s}}{100.0 \text{ Hz}} = 15 \text{ m} \][/tex]
Next, calculate the wavelength in air:
[tex]\[ \lambda_{\text{air}} = \frac{v_{\text{air}}}{f} = \frac{340 \text{ m/s}}{100.0 \text{ Hz}} = 3.4 \text{ m} \][/tex]
To find out how many times larger the wavelength in water is compared to the wavelength in air, we divide the wavelength in water by the wavelength in air:
[tex]\[ \text{Ratio} = \frac{\lambda_{\text{water}}}{\lambda_{\text{air}}} = \frac{15 \text{ m}}{3.4 \text{ m}} \approx 4.4 \][/tex]

65 liters of oil leaks out during the first hour.
What is Oil leaks?When the oil filter gradually becomes looser or the oil gasket is improperly tightened, car or engine oil leaks happen.
These are also known as oil filter leaks, and generally speaking, the filter gasket should be tightened in accordance with the manufacturer's instructions.
Sometimes, a gasket and bolts are used to secure an external oil pump to the engine block. These parts are prone to wear and leakage. Lack of oil in the oil pump can result in severe damage, including early wear of the pump and oil starvation of the engine.
Therefore, 65 liters of oil leaks out during the first hour.

A dry cleaner throws a 20 kg bag of laundry onto a stationary 8.3 kg cart. the cart and laundry bag begin moving at 2.6 m/s to the right. find the velocity of the laundry bag before the collision. answer in units of m/s. answer
Final answer:
Using the conservation of momentum, the velocity of the 20 kg laundry bag before the collision is calculated to be approximately 3.689 m/s to the right.
Explanation:
To find the velocity of the laundry bag before the collision, we can use the conservation of momentum, which states that the total momentum before an event is equal to the total momentum after the event, provided no external forces act on the system. Since the cart is initially stationary, its initial momentum is 0. After the bag is thrown onto the cart, both move together with a certain velocity, so the final momentum is the combined mass times the final velocity. We can set up the equation as follows:
Momentum before collision (p₁) = Momentum after collision (p₂)
Since the cart is stationary before the collision, this simplifies to:
Velocity of the bag before collision (v) × Mass of the bag [tex](m_{bag)[/tex] = (Mass of the bag [tex](m_{bag)[/tex] + Mass of the cart [tex](m_{cart)[/tex]) × Final velocity [tex](v_f)[/tex]
Inserting the given values, we get:
v × 20 kg = (20 kg + 8.3 kg) × 2.6 m/s
Now we solve for the velocity (v):
v = (28.3 kg × 2.6 m/s) / 20 kg
v = 3.689 m/s
Therefore, the velocity of the laundry bag before the collision was approximately 3.689 m/s to the right.

Determine the Kinetic energy of a 1000 kg roller coaster car that is moving with speed of 20.0 m/s
Final answer:
The kinetic energy of a 1000 kg roller coaster car moving at a speed of 20.0 m/s is calculated using the formula KE = ½ mv², resulting in KE = 200,000 J or 2.00 × 10⁵ J.
Explanation:
The question requires us to calculate the kinetic energy of a 1000 kg roller coaster car that is moving with a speed of 20.0 m/s. The kinetic energy (KE) of an object can be found using the formula KE = ½ mv², where m is the mass of the object and v is its velocity. Inserting the given values into the formula, we get:
KE = ½ (1000 kg) (20.0 m/s)
KE = ½ (1000 kg) (400 m²/s²)
KE = (500 kg) (400 m²/s²)
KE = 200,000 J or 2.00 × 10⁵ J
The roller coaster car possesses 200,000 joules of kinetic energy at the given speed.
A shot hitting the birdie high and deep to the backcourt is called what
Final answer:
In badminton, a shot that sends the birdie high and deep to the backcourt is called a clear. It's a defensive move to create more playing space and opportunities.
Explanation:
A shot in badminton that is hit high and deep into the opponent’s backcourt is known as a clear. This type of shot is a defensive move, intended to give the player hitting the clear more time to return to a ready position and to push the opponent to the rear of their court, potentially creating opportunities for future aggressive plays. The clear can be performed as either a forehand or backhand stroke depending on the player's position and the shuttlecock's trajectory.

You hop on the carousel horse. The attendant flips the switch and you move up and down, around and around. When the ride ends, the attendant again flips the switch. The up and down motion stops, as you continue to move in a circular motion, gradually slowing to a stop. Why? A) All the mechanical energy of the carousel is lost. B) All of the kinetic energy is converted to potential energy. C) The external energy source overcomes the internal energy of the carousel. D) Mechanical systems need an external energy source to maintain their
Answer:
D) Mechanical systems need an external energy source to maintain their
Explanation:
Mechanical systems need an external energy source to maintain their motion.
In this case, electrical energy is transformed to mechanical energy. Without electrical energy, the carousel slows due to friction and eventually stops.
An antique carousel that’s powered by a large electric motor undergoes constant angular acceleration from rest to full rotational speed in 5.00 seconds. When the ride ends, a brake causes it to decelerate steadily from full rotational speed to rest in 11.0 seconds. Compare the torque that starts the carousel to the torque that stops it. τstart/τstop = the tolerance is +/-2%

A certain wave has a wavelength of 35 meters and a frequency of 4.0 Hz. What is the speed of the wave? 8.8 m/s 31 m/s 39 m/s 140 m/s
Answer:
Speed, v = 140 m/s
Explanation:
It is given that,
Wavelength, λ = 35 meters
Frequency of the wave, υ = 4 Hz
The speed of the wave is the product of the frequency and the wavelength of the wave.
Mathematically, it can be written as :
v = υ λ
v = 35 m × 4 Hz
v = 140 m/s
So, the speed of the wave is 140 m/s
Hence, this is the required solution.

) with the box still on the truck, the truck attains its maximum velocity. as the truck comes to a stop at the next stop light, what is the magnitude of the maximum deceleration the truck can have without the box sliding?
Final answer:
The magnitude of the maximum deceleration to keep the box from sliding is determined by the coefficient of static friction and gravity; it can be calculated as 2.352 m/s² for a coefficient of 0.24.
Explanation:
The question deals with the concept of friction and deceleration in the context of a box placed on a truck that is coming to a halt. To prevent the box from sliding, the maximum deceleration is dictated by the coefficient of static friction.
This coefficient, multiplied by the acceleration due to gravity, gives us the maximum deceleration the truck can have without the box beginning to slide.
To calculate this, we can use the formula maximum deceleration (a_max) = coefficient of static friction (μ_s) × acceleration due to gravity (g), where μ_s is 0.24 and g is approximately 9.8 m/s².
Thus, a_max = 0.24 × 9.8 m/s², which results in a maximum deceleration of 2.352 m/s² without causing the box to slide.

The tangential speed at the outer rim of a Ferris wheel is 10 m/s. What is the tangential speed of a position halfway from the center to the outer rim?
In rotational motion, tangential speed is proportional to the radius. Thus, if you're halfway between the center and the rim of a Ferris wheel, your speed would be half that of the rim's speed. So, the tangential speed halfway to the center from the rim would be 5 m/s assuming the outer rim speed is 10 m/s.
Explanation:The concept you're asking about is related to tangential speed and its relationship to the radius in rotational motion. In the case of a Ferris wheel, or any rotating body, the tangential speed is defined as the angular velocity times the radius. Therefore, if the radius is halved (a point halfway from the center to the outer rim), the tangential speed at the new point will also be halved assuming a constant angular velocity. Thus, in your example, if the tangential speed at the outer rim is 10 m/s, the speed halfway to the center will be 5 m/s.
This is because the properties of a rotating body dictate that the tangential speed increases linearly with the radius from the axis of rotation, in the case of a constant angular velocity. Hence, the farther away from the center of rotation, the faster the tangential speed, and vice versa.

The tangential speed at a position halfway from the center to the outer rim of a Ferris wheel with an outer rim speed of 10 m/s would be 5 m/s.
The tangential speed at a position halfway from the center to the outer rim of a Ferris wheel is half of the tangential speed at the outer rim. In this case, the initial tangential speed at the outer rim is given as 10 m/s, so the tangential speed at halfway to the rim would be 5 m/s. This is because tangential speed is directly proportional to the radius in uniform circular motion, and if the radius is halved, so is the tangential speed.
