Question:
Use your knowledge of waves in the graph shown to determine the frequency of wave C. What does it tell you about the speed of the wave?
Answers
"Frequency" means how often something happens. When you say how many times it happens every SECOND, you can call the number Hertz, or Hz.
In the graph, there are 10 vibrations in 10 seconds, 20 of them in 20 seconds, and 30 in 30 seconds. This should pretty much shout at you "THERE'S ONE VIBRATION EVERY SECOND !". When you realize that, you can say the frequency of the vibration is 1 Hz.
The graph tells us nothing about the speed of the waves. I suspect there's another picture to the question that you didn't include. If the other part shows the wavelength, then we could figure out the speed. But with just what you're showing us, we can't.

How might electric fields be involved in a levitation device?
Answers
Answer:
When a magnet is moving relative to a conductor in close proximity, a current is induced within the conductor. This induced current will cause an opposing magnetic field. This opposing magnetic field can be used to levitate a magnet.

9.0 cm/s. Determine which insect is ahead
and by how much after 30 min. Assume both
insects are moving in the same direction.
Answers
Answer:
insect B by 12m
Explanation:
30min = 1800s (times by 60)
5m/min x 30min = 150m
9cm/s x 1800s = 16,200cm = 162m
162m - 150m = 12m

A 62 kg male ice skater is facing a 42 kg female ice skater. They are at rest on the ice. They push off each other and move in opposite directions. The female skater moves backwards with a speed of 3.7 m/s. What is the velocity of the male skater?
Answers
The velocity of the male skater is 2.5 m/s in opposite to the direction of the female skater moving.
What is the law of conservation of momentum?According to the law of conservation of momentum, The overall momentum of two or more bodies acting on one another in an isolated system stays constant unless an external force is introduced. As a result, momentum cannot be gained or lost.
Given parameters:
The mass of the male ice skater is: M = 62 kg.
The mass of the female ice skater is: m = 42 kg.
Initially both of them are in rest.
After they push off each other and move in opposite directions, the female skater moves backwards with a speed of v =3.7 m/s.
Let the speed of the male ice skater is V m/s now.
From the law of conservation of momentum:
MV + mv = 0
V = - mv/M
= - (42×3.7)/62 m/s
= - 2.5 m/s
Hence, the velocity of the male skater is 2.5 m/s in opposite to the direction of the female skater moving.

Explanation:
The kinetic energy of an object is the energy possessed by the object due to its motion. It is given by:
where
m is the mass of the object
v is its speed
From the equation, we notice that the kinetic energy is:
Directly proportional to the mass
Proportional to the square of the speed
In this problem, the initial kinetic energy of the object is
K = 100 J
Later, the speed of the object is doubled:
v' = 2v
Therefore, the new kinetic energy will be
So, we see that the kinetic energy will quadruple.

A 400 hp engine in a 1,600 kg car applies maximum force for 2 seconds to accelerate the car onto the
interstate. If the car moves at 8 m/s before accelerating, what is its speed after the 2 seconds of acceleration?
Answers
Answer:
I will assume that “maximum force” implies the constant application of power P = 400 hp (international) to accelerating the vehicle. The force will therefore vary with speed as the vehicle accelerates. I will also assume that all engine energy goes into accelerating the vehicle, rather than rotating elements like its wheels.
In this case the 400 hp (equivalent to 298,280 watts) is applied for time t = 2 seconds. Therefore the kinetic energy of the vehicle is increased by:
ΔKE=Pt=(298,280)(2)=596,560 joules.
The initial kinetic energy is:
KEinitial=12mv2
=(0.5)(1600)(82)=51,200 joules.
Therefore final kinetic energy is:
KEfinal=KEinitial+ΔKE
=51,200+596,560
=647,760 joules
Therefore final vehicle velocity can be found:
KEfinal=12mv2
v=2KEfinalm−−−−−−−−√
=(2)(647,760)1600−−−−−−−−−−−√
= 28.455 m/s

Answers
Answer:
[tex]\boxed {\boxed {\sf v= 0.08 \ km/min \ North}}[/tex]
Explanation:
Velocity is found by dividing the displacement by the time.
[tex]v=\frac{s}{t}[/tex]
where s is the displacement and t is the time.
The displacement is 1.6 kilometers, but it needs a direction as well. The question notes you walked North. The time is 20 minutes.
[tex]s= 1.6 \ km \ North \\t= 20 \ min[/tex]
[tex]v=\frac{1.6 \ km \ North} { 20 \ min}[/tex]
Divide.
[tex]v= 0.08 \ km/min \ North[/tex]
Velocity is a vector quantity, so that is why it has the measurement and the direction.
The average velocity is 0.08 kilometers per minute North.
