The phases where surfer’s most likely benefit include D. 1st Quarter and 3rd Quarter.
Surfers will benefit include during the 1st Quarter and 3rd Quarter because there's tidal change. Tidal change is when coastal areas experience two low and high tides.
The benefit of surfing during this period is that it helps jack the waves. Waves transmit energy and this is important to surfers.

what is mass times acceleration?
Answer:
Force
Explanation:
The mass of an object is the quantity of matter it contains. It is measured in kilograms.
Acceleration is the ratio of the change in the velocity of an object to the change in time. It is measured in m/[tex]s^{2}[/tex].
When the mass of an object is multiplied with its acceleration, this gives the average force applied on the object. As force is defined as agent that can change the state of an object.
i.e F = m × a
where F is the force, m is the mass of the object and a its acceleration.
The two major classes of force are; contact force and field force.
This graph provides data on the amount of water needed to grow four different crops, each used to produce ethanol, a fuel. For each crop, the data shows how many liters of water are needed to produce one liter of ethanol fuel. Which of the following would require using the most water? *
Producing 100 L of ethanol from sugar cane
Producing 200 L of ethanol from sugar beet
Producing 300 L of ethanol from potatoes
Producing 400 L of ethanol from corn
Answer:
Producing 300 L of ethanol from potatoes
Explanation:
From the diagram, one liter of ethanol production from sugar cane requires 2000 liters of water. Hence, in order to produce 100 L of ethanol from sugar cane, 2000 x 100 = 200,000 L of water.
1000 liters of water is needed to produce 1 liter of ethanol from sugar beet. Hence, 200 x 1000 = 200,000 L of water will be needed to produce 200 liters of ethanol.
1000 liters of water is also required to produce 1 liter of ethanol from potatoes, hence, 300 x 1000 = 300,000 L of water would be required to produce 300 L of ethanol from the same material
About 500 liters of water is required to produce 1 liter of ethanol from corn, hence, 400 x 500 = 200,000 L of water would be needed to produce 400 L of ethanol from corn.
In conclusion, producing 300 L of ethanol from potatoes would require using the most water among all the options.
Which term is defined as the force applied to the object divided by the mass of the object?
speed
velocity
mass
acceleration
Answer:
acceleration
Explanation:
From the question: "FORCE... divided by the MASS..." is translated to a math equation as "F / m", where "F" is the force and "m" is the mass.
Now, the second Newton's law says "F = m . a ", where a is acceleration.
If you move m to the left side, clearly you have "F / m", and "a" is alone to the right. Math equation:
a = F / m
acceleration = force / mass

A pendulum reaches a height of 0.3 m at the top of its swing. If the
bob has a mass of 5 kg, what is the potential energy at the top of its
swing?
Select one:
14.7)
7.35 J
0.45 J
1.5 J
Answer: A
Potential energy = 14.7 J
Explanation:
Given that the
Mass M = 5 kg
Height h = 0.3 m
Let us take acceleration due to gravity g = 9.81 m/s^2
Potential energy = mgh
Substitute all the parameters into the formula above
P.E = 5 × 9.81 × 0.3
P.E = 14.715 J
P.E = 14.7 J approximately
The correct option is therefore A

What is the kinetic energy of a bicylcle with a mass of 15 kg traveling at a velocity of 3 m/s?
KE = 0.5 x mv^2
Kinetic energy equals 1/2 times mass times velocity squared.
Mass = 15kg
Velocity = 3m/s
Plug it into the formula.
KE = 0.5 x 15(3^2)
KE = 0.5 x 15(9)
Multiply the mass and velocity squared.
KE = 0.5 x 135
Then, multiply the result by 1/2 or 0.5
KE = 67.5
The kinetic energy of a bicycle that has a mass of 15kg and travels at 3m/s is 67.5J.
Answer:
67.5 J
Explanation:
Kinetic energy can be found using the following formula.
[tex]KE=\frac{1}{2}mv^2[/tex]
where m is the mass in kilograms and v is the velocity in m/s.
We know the bike has a mass of 15 kilograms. We also know the velocity is 3 m/s. Therefore, we can substitute 15 for m and 3 for v
[tex]KE=\frac{1}{2}*15*3^2[/tex]
Evaluate the exponent first. 3^2 is the same as 3*3, which is equal to 9.
[tex]KE=\frac{1}{2} *15*9[/tex]
Multiply 15 and 9.
[tex]KE=\frac{1}{2} *135[/tex]
Multiply 1/2 and 135
[tex]KE=67.5[/tex]
Add appropriate units. Kinetic energy uses Joules or J as the units.
[tex]KE= 67.5 Joules[/tex]
The kinetic energy of the bike is 67.5 Joules
