Frequency of the waves is 0.05 Hz
Number of complete wavelength, λ = 6
therefore distance covered = 6 Wavelength
Time taken to complete 6 wavelengths, t = 2 min
Since 1 min = 60 sec
2 min = 2 * 60 = 120 sec
Frequency can be defined as the number of wave cycles completed per second by a wave.
It is the ratio of velocity to the wavelength.It is denoted by FThe unit used for the frequency is hertz, Hz.Mathematically, F = [tex]\frac{Velocity}{Wavelength}[/tex]As we know, Velocity = [tex]\frac{Distance}{Time}[/tex] = [tex]\frac{6 Wavelength}{120}[/tex]
F = [tex]\frac{Velocity}{Wavelength}[/tex]
F = [tex]\frac{6 wavelength}{120 wavelength}[/tex]
F = [tex]\frac{6}{120}[/tex]
F = 0.05 Hz

A Bicycle is turned upside down the front wheel is running,where will the valve stop
The valve will stop when the wheel stops.
How can the wheel stops?
It can be done either applying the force manually or let the natural friction force work.The force can be applied manually by pulling up the brakes.The other way by which it stop is :
When we ride on a bicycle, we rotate the pedals, which in turn rotate the chainrings, which rotate the rear sprocket, hence, making the rear wheel to move forward. This rotation brings in angular speed and angular acceleration.The friction is applied from the ground to stop it from slipping. Here, the forces working are the rotational and the frictional along with angular acceleration and speed. When the bicycle is upside down, the frictional force from the ground becomes zero. The chain rings also don’t control the front wheel. The angular acceleration will be opposed by some force. Here, the frictional force that will act will be from the air and the inertia is applied to the rotational motion of the wheel which is now in the air and not on the ground. Once the friction from air is greater than angular motion, the wheel stop automatically.To know more about angular motion, refer : https://brainly.com/question/14723674

What is her x position at t=0.80s ?
What is her y position at t=0.80s ?
What is her x velocity component at t=0.80s ?
What is her y velocity component at t=0.80s ?
a. Her x position at t = 0.80 s is 0.0832 m

c. Her x velocity component at t = 0.80s is 2.08 m/s
d. her y velocity component at t = 0.80s is -3.6 m/s
Since the skateboarder travels on a horizontal surface with an initial velocity of 3.6 m/s toward the south and a constant acceleration of 2.6 m/s² toward the east.
Her velocity v = (0i - 3.6j) m/s and her acceleration a = (2.6i + 0j) m/s²a. What is her x position at t = 0.80s ?Now since she starts from the origin, to find her x position after 0.80 s, using the equation of motion for the x - components of motion,
x = ut + 1/2at² where
u = x - component of velocity = 0 m/s, a = x - component of acceleration = 2.6 m/s² and t = time = 0.8 sSo, substituting the values of the variables into the equation, we have
x = ut + 1/2at²
x = 0 m/s × 0.8 s + 1/2 × 2.6 m/s² × (0.8 s)²
x = 0 m + 1.3 m/s² × 0.64 s²
x = 0 m + 0.832 m
x = 0.832 m
So, her x position at t = 0.80 s is 0.0832 m
b. What is her y position at t = 0.80s ?Using the equation of motion for her y - components of motion, her y position is y = ut + 1/2at² where
u = y - component of velocity = -3.6 m/s, a = y - component of acceleration = 0 m/s² and t = time = 0.8 sSo, substituting the values of the variables into the equation, we have
y = ut + 1/2at²
y = -3.6 m/s × 0.8 s + 1/2 × 0 m/s² × (0.8 s)²
y = -3.6 m × 0.8 s + 0
y = -28.8 m
So, her y position at t = 0.80 s is -28.8 m
c. What is her x velocity component at t = 0.80s ?Using the equation of motion for her x - component of motion, her x velocity compoent after t = 0.8 s is
v = u + at where
u = initial x - component of velocity = 0 m/s, a = x - component of acceleration = 2.6 m/s² and t = time = 0.8 sSo, we have
v = u + at
v = 0 m/s + 2.6 m/s² × 0.8 s
v = 0 m/s + 2.08 m/s
v = 2.08 m/s
So, her x velocity component at t = 0.80s is 2.08 m/s

v = u + at where
u = initial y - component of velocity = -3.6 m/s, a = y - component of acceleration = 0 m/s² and t = time = 0.8 sSo, we have
v = u + at
v = -3.6 m/s + 0 m/s² × 0.8 s

A construction worker on the 24th floor of a building project accidentally drops a wrench and yells “Look out below” Could a person of ground level hear his warning in time to get out of the way? The speed of sound is about 1100 feet per second
Answer:
Assuming the height at which the wrench was dropped is 336 feet,
the person will hear the sound in 0.3 sec and the wrench will hit the ground only after 4.58 seconds so there is enough time to get out of the way
Explanation:
Without knowing the exact height at which the 24th floor is located, it would be difficult to determine whether the wrench will hit the ground before the sound hits the ground
Realistically, we can assume each floor of the building is 14' high
So the height at which the 24th floor is located is 24 x 14 = 336 feet
To travel 336 feet at 1100 feet per second, sound will take 336/1100 seconds which is 0.30 second
Let's compute the time taken for the wrench to hit the ground
The acceleration due to gravity is usually taken to be 16 feet/second²
The displacement which is the distance traveled by an object with an initial velocity of u in time t is given by the equation:
s = ut + (1/2)t²
Here the initial velocity is 0
So the equation is
s = 1/2 x 32 x t² = 16t²
To cover 336 feet we substitute 336 for s and get
336 = 16t²
t² = 336/16
t = ±√(336/16) ≈ 4.58 seconds (we only take the positive root)
So the person will hear the sound in 0.3 sec and the wrench will hit the ground only after 4.58 seconds so there is enough time to get out of the way
In general, we can state that if the height from which the wrench was dropped is h then time t taken for wrench too hit the ground is
t = √(h/16) seconds
If this is greater than the time taken for sound to travel the same distance then the person can get out of the way

The metric conversion of the following quantities is calculated as follows;
5 KL = 5 x 1000 L = 5,000 L
3L = 3 x 1/1000 L = 0.003 KL
4g = 4 x 1/1000 g = 0.004 kg
81 kg = 81 x 1000 g = 81,000 g
52 dg = 52 x 1/10 g = 5.2 g
3 dm = 3 x /10 m = 0.3 m
14 mm = 14 x 1/1000 m = 0.014 m
Thus, the metric conversion of the given quantities is determined as

What will be the acceleration of an object at rest with 70kg if the force exerted is 1400N?
Force = (mass) x (acceleration)
so
Acceleration = Force / mass
Acceleration = (1400 N) / (70 kg)
Acceleration = 20 m/s²
