When waves traveling in the same medium meet, a new
wave may be produced. Use the slider to create the resulting
wave with the largest amplitude.
Answers
Answer:
if there is any phase between the waves this value is less
if the sine function is ±, the amplitude of the total wave is
A_total = A₁ + A₂ + A₃+ A₄ +A₅
Explanation:
When several waves travel in the same direction, the process of adding them can take place.
y_total = ∑ \(y_{i}\)
where
y_{i} = A_{i} sin (k x - w t + Ф)
with fi the phase of each wave
To produce the largest possible result, all waves must come with the same phase
y_total = (A₁ + A₂ + A₃ + A₄ + A₅) sin (k x - wt)
if there is any phase between the waves this value is less
if the sine function is ±, the amplitude of the total wave is
A_total = A₁ + A₂ + A₃+ A₄ +A₅

Answers
Answer:
Forty million years ago, the continent of India, which was being carried northward by the Indo-Australian plate, collided with Asia forming the Himalayan mountain range (fold mountains). Since the initial encounter, the subcontinent of India has moved 2,000 kilometers farther north at a rate of 5 centimeters a year, sliding beneath Asia as it moves. In 10 million years India will plow into Tibet a further 180km. This is about the width of Nepal.

(i did number 1) James Watt was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine. In 1762, he began studying steam engines. With his knowledge, in 1763, he repaired a "Newcomen" engine owned by the university. However, while repairing it, he was impressed by its waste of steam, and came upon a solution, the separate condenser. It was his first invention, and he created it in 1769. In 1765, he produced his first working model of the 'Watt' engine (with separate chambers for piston and steam). (i rly hope this helps no need to mark branliest if it doesnt)
Explanation:
A driver is driving a 6371 kg lorry. After spotting a hazard, the driver applies the brakes. The lorry decelerates uniformly and comes to a stop 60 m after the brakes are applied. Estimate the braking force needed to stop the lorry.
Answers
Answer:
The estimated braking force needed to stop the lorry is zero, based on the given information and calculations. However, it's important to note that this result is likely not accurate, as some force is required to stop a moving object. It's possible that additional information or calculations are needed to obtain a more realistic estimate of the braking force.
Explanation:
To estimate the braking force needed to stop the lorry, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).
In this case, the lorry decelerates uniformly, so the acceleration is constant. The initial velocity is assumed to be zero since the lorry comes to a stop. The final velocity is also zero. Therefore, we can use the equation:
Final velocity squared (vf^2) = Initial velocity squared (vi^2) + 2 * acceleration (a) * distance (d)
Since vi = 0 and vf = 0, the equation simplifies to:
0 = 0 + 2 * a * d
Solving for acceleration (a), we have:
2 * a * d = 0
a = 0
Since the acceleration is zero, it means that the braking force needed to stop the lorry is also zero. This is likely not an accurate result as some force is required to stop the lorry. It's possible that additional information or calculations are needed to accurately estimate the braking force.
The braking force required to stop a 6371 kg lorry after spotting a hazard and applying the brakes is what the question is asking for. The lorry decelerates uniformly and comes to a stop 60 meters after the brakes are applied.
The following steps will guide you on how to calculate the braking force:
Step 1: Determine the mass of the lorry which is 6371 kg. This will be denoted as m.
Step 2: Determine the distance travelled by the lorry, which is 60 m.
Step 3: Determine the time taken by the lorry to stop. This can be done by using the formula for uniform deceleration, which is a = (v-u)/t where v is the final velocity, u is the initial velocity and a is the uniform deceleration. Since the lorry comes to a stop, its final velocity is zero and its initial velocity is unknown.
However, we can assume that the lorry was initially travelling at a constant speed before spotting the hazard. Therefore, we can assume that the initial velocity was equal to the average velocity of the lorry before the brakes were applied.
This can be calculated using the formula v = d/t where d is the distance travelled and t is the time taken. The average velocity can therefore be calculated as follows: v = d/t = 60 m/t
Step 4: Rearrange the formula for uniform deceleration, a = (v-u)/t, to find u which is the initial velocity. Since the lorry comes to a stop, we know that v = 0.
Therefore: u = v - at where a is the uniform deceleration and t is the time taken to stop which is also equal to the time taken for the lorry to travel the distance of 60 meters. Substituting for v, we get: u = - at
Step 5: Calculate the acceleration of the lorry using the formula a = (v-u)/t. Since the final velocity is zero, we get: a = -u/t = -(-at)/t = a The acceleration is negative since the lorry is decelerating.
Step 6: Calculate the braking force using the formula F = ma where F is the braking force and m is the mass of the lorry. Therefore: F = ma = (-ma) since a is negative = (-6371 kg) (a) Therefore, the braking force required to stop the lorry is -6371a N where a is the uniform deceleration calculated in Step 5.

The mechanical energy in the wind was transferred to the table, which caused it to shake and move the papers.
Answers
Answer: Option c
Explanation: Wind has kinetic energy to move objects from their places. It is vastly used across the world for the production of electricity.
By turning the kinetic energy of moving air into electrical, the wind is used to generate power. Wind drives the rotor blades of contemporary wind turbines, which transform kinetic energy into rotational energy. A shaft transmits this rotational energy to the generator, which generates electrical energy. More than a century ago, the first wind turbines appeared. After the electric generator was developed in the 1830s, engineers began experimenting with harnessing wind power to create electricity. However, modern wind power is thought to have been invented in Denmark, where horizontal-axis wind turbines were built in 1891 and a 22.8-meter wind turbine started operating in 1897. Wind power generation occurred in the United Kingdom and the United States in 1887 and 1888.

Please help: The average depth of water in a place near the coast of th Pacific ocean is 5.om. The largest tidal range in that place is 2.0m. Calculate the maximum depth of water at that place. please do not attempt to steal points... thank you <3!
Answers
Answer:
The maximum depth of the water at the place is 6.0 meters.
Given the tidal range and average depth, it is to be noted that the maximum depth of the water at the place, is 6.0 meters.
How can you calculate Maximum Depth using Average Depth and Tidal Range?The tidal range is the successive difference between tide highs and lows, which is a sinusoidal pattern. On the basis of the above, it is correct to state that the tidal range is twice of the amplitude of the tide level.
That is:
The Amplitude of the tide, A = 2.0/2m = 1m
The maximum depth at the place, therefore, is given as:
D\(_{max}\) = A + D\(_{ave}\)
Hence,
D\(_{max}\) = 1.0 + 5.0 = 6.0
Thus, it is correct to state that the Maximum Depth (D\(_{max}\)) = 6.0 Meters.

Answer:
Explanation: COMPOST BIN
WHAT IS A COMPOST BIN?
A compost bin is a container into which you place organic waste to turn into compost (organic material) over time.
Most compost bins are designed to hasten the decomposition of organic matter through proper aeration and moisture retention. With the proper combination of air and moisture, ideal conditions are produced for the activity of aerobic organisms responsible for the high temperatures that transform the organic materials into compost
Read on to find out how to start a compost bin, DIY compost bin ideas, and more tips for beginners.
The decomposition process will eventually take place over time in a compost "pile" or "heap," even without any housing to contain the matter. However, a compost bin is worth it because it helps speed up decomposition and keeps the area neat. Some bins are continuous, meaning you can keep adding waste to them, while others create batches of compost with a set mix of ingredients you add all at once. Depending on the style of compost bin you choose, bins can also have the advantage of making it harder for rats to get at your compost. This is true of the tumbler type, for example.
CHOOSING THE RIGHT BIN
Select the right bin for your composting needs. You can make an inexpensive compost container out of almost any container or material. Some ideas include:
Plastic storage container
Plastic bucket
Trash cans
Straw bales
Lumber
Branches harvested from the woods
Stone
Cinder blocks
Wire fencing
Ceramic (also popular for a kitchen countertop compost bin)
The best bin, however, is one you can easily turn or rotate consistently to control odors and make sure all the materials decompose. This is especially important for aerobic composting (more information below). A tumbler composting bin is pricey, but you can DIY one from barrels and sawhorses. You can turn compost with a rake or shovel in a non-rotating bin, it just takes more labor to do so.
