A wave traveling at 50.0 m/s has a wavelength of 10.0 m. What is the frequency of the wave? Show your work below?
Answer:
The frequency of the wave is 5 Hz
Explanation:
Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).
Frequency is the number of vibrations that occur in a unit of time. Its unit is s – 1 or hertz (Hz).
The propagation velocity is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave disturbance propagates along its displacement. Relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation: v = f * λ.
In this case:
v= 50 [tex]\frac{m}{s}[/tex]f=?λ= 10 mReplacing:
50 [tex]\frac{m}{s}[/tex] = f* 10 m
Solving:
[tex]f=\frac{50 \frac{m}{s} }{10 m}[/tex]
f=5 Hz
The frequency of the wave is 5 Hz
what is the difference between distance and displacement? give an example of each.
Answer: Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Explanation: hope it helps :)
how does speed affect the amount of kinetic energy an object has?
Answer:
The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has

Use Hooke's Law and Newton's 2nd Law to derive a formula for the acceleration of an object of mass m on a frictionless surface which is attached to a spring with a constant k which is stretched a distance L. The acceleration should be in terms of m, k, and L.
Answer:
a = kL/m
Explanation:
Here we can use Hooke's Law to find out the force applied on the system. Hooke's Law states that when a spring is stretched by some force, the force applied is directly proportional to the displacement of spring. The formula is given as:
F = kL
Now, the Newton's Second Law of motion states that whenever an unbalanced force is applied to a body it produces an acceleration in the body, in its own direction. So, the force is given by the formula:
F = ma
Comparing both the forces, we get:
kL = ma
a = kL/m
define polarization (igcse answer please)
Answer:
the action of polarizing or state of being or becoming polarized: such as the action or process of affecting radiation and especially light so that the vibrations of the wave assume a definite form. Polarization, in Physics, is defined as a phenomenon caused due to the wave nature of electromagnetic radiation. There are two types of waves, transverse waves, and longitudinal waves.

Three students are fighting over a T-shirt. Student 1 exerts a constant force F⃗ 1=F0i^ on the shirt, student 2 exerts a constant force F⃗ 2=−3F0j^ and student 3 exerts a constant force F⃗ 3=−4F0i^+Gj^. (In these expressions F0 and G are positive constants with units of force.) As the three students exert these forces, the T-shirt undergoes a straight-line displacemen 2di^+dj^ where d is a positive constant with units of distance. Find the work done on the T-shirt by student 1.
Answer:
W₁ = 2F₀d
Explanation:
When a force is applied on a body, due to which the body displaced by some distance, then the work is said to be done. Hence, the work is the dot product of the force nd displacement.
W = F.d
where,
W = Work Done
F = Force Applied
d = Displacement
For student 1:
W = W₁ = ?
F = F₁ = F₀ i
d = 2d i + d j
Therefore,
W₁ = (F₀i).(2di + dj)
W₁ = 2F₀d(i.i) + F₀d(i.j)
W₁ = 2F₀d(1) + F₀d(0)
W₁ = 2F₀d + 0
W₁ = 2F₀d
How can you use a Position vs. Time graph to describe an object’s speed or direction of motion
Answer:
In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure below, then the slope is zero and so is the velocity. The position of the object is not changing.

In an experiment, students were given an unknown mineral. The unknown mineral was placed in 150 ml of water. Once in the water, the volume went up to 165 ml. Then when the same object was dried, then massed on a balance. It had a mass of 225 grams. What is the density of the unknown mineral? Note: You only have to fill in the numerical answer.
Answer:
15
Explanation:
225/(165-150)=15g/cm3

What is the magnitude of the total displacement of the school bus from the start to the end of its trip?
Answer:
With the given information, we can assume that the start and the end of the trip are the same place. (Suppose, a tour where the bus starts at the school, then it goes to a given location, and then it returns to the school)
Now, the definition of displacement is:
The difference between the final position and the initial position.
But if the start and the end of the trip are the same place, then the initial and final position must be the same. Then the difference between the final position and the initial position is zero.
This means that the displacement of the school bus from the start to the end of its trip must be zero.

Answer:
90cm
Explanation:
2x5=10
10x9=90
Answer:
90 cm
Explanation:
To find volume, the formula is V=LWH
L is the length, W is the width and H is the height:
9 x 5 x 2 = 90
So V = 90 cm
