what is the wavelength of waves at the beach if they have a frequency of 0.3 Hz and they move at 7.1 m/s?
Answers
Answer:
23.67 m
Explanation:
We are given;
Frequency; f = 0.3 Hz
Speed; v = 7.1 m/s
Now, formula to get the wavelength is from the wave equation which is;
v = fλ
Where λ is wavelength
Making λ the subject, we have;
λ = v/f
λ = 7.1/0.3
λ = 23.67 m

g In principle, both the motion of a simple pendulum and the motion of a mass on a horizontal ideal spring can be used to measure time (via their periods of oscillation). But one of these two types of clocks loses it's accuracy (must be re-calibrated) when taken to high altitudes. Which type of clock is this, and why? Explain in detail please.
Answers
Answer:
In a system with a hanging mass and an inextensible wire, the force is proportional to the sino, in the case of small oscillations, approximately the stop angle, this hiss is lost, the calibration for large amplitudes is lost.
Explanation:
In a spring-mass system the restoring force created by the spring is proportional to displacement from the equilibrium position, therefore this watch does not require streamlining as the amplitude of movement increases.
In a system with a hanging mass and an inextensible wire, the force is proportional to the sino, in the case of small oscillations, approximately the stop angle, this hiss is lost, the calibration for large amplitudes is lost.
It is winter. You are very cold. Your body systems cooperate and respond to the cold in three ways in an effort to keep you warm. Choose the answer that is NOT correct.
Your nervous system slows down and the impulses that move your muscles also slows, helping to retain heat.
The body will try to generate heat itself by allowing muscles and organs to shake within the body: this is known as shivering.
Blood flow is diverted from muscle tissue to fat. The rapid decomposition fat (adipose) tissue generates heat energy that helps to raise the body's temperature.
Cold causes blood vessels to constrict and blood flow resistance to increase. Reducing blood flow to the skin and the extremities reduces heat transferred to the environment.
Answers
Answer:
The third option
Explanation:
A and B are true because this can be noticed by just any human. So then you are left with C and D. With these two, D makes more sense. Since when someone gets cold, their blood flow is reduced starting in areas like your fingers, hands, toes and feet. These areas get the coldest since they are the smallest and furthest away from the rest of your body. Also since these areas touch surfaces more than other areas, they will have less heat to transfer.

which of the following quantities can be measured in the same units as Work?
speed times velocity, momentum time speed, forces times velocity, kinetic energy, mass times acceleration, kumquats, potential energy, momentum, weight times acceleration
Answers
Answer:
Kinetic energy and potential energy.
Explanation:
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v^2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. Kinetic energy is usually measured in units of Joules (J); one Joule is equal to 1 kg m^2 / s^2.
The formula for potential energy depends on the force acting on the two objects. For the gravitational force, the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m/s^2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m^2/s^2. In fact, all energy has the same units, kg m^2/s^2, and is measured using the unit Joule (J).
Work is also measured with the unit Joule (J).

Lord Beckett and members of the EIT Co. spot the Black Pearl in the distance making its way towards land. As a
precaution, Lord Beckett orders a cannon to be shot towards Captain Jack Sparrow. The cannonball goes a horizontal
distance of 275 m after leaving the 100. m high cliff. If the cannonball was launched from horizontal, at what velocity
did it leave the cannon? At what velocity (resultant speed + angle) did it hit the sea? (Clearly, they missed the ship!)
Show work
Answers
Answer:
Explanation:
The cannonball goes a horizontal distance of 275 m . It travels a vertical distance of 100 m
Time taken to cover vertical distance = t ,
Initial velocity u = 0
distance s = 100 m
acceleration a = 9.8 m /s²
s = ut + 1/2 g t²
100 = .5 x 9.8 x t²
t = 4.51 s
During this time it travels horizontally also uniformly so
horizontal velocity Vx = horizontal displacement / time
= 275 / 4.51 = 60.97 m /s
Vertical velocity Vy
Vy = u + gt
= 0 + 9.8 x 4.51
= 44.2 m /s
Resultant velocity
V = √ ( 44.2² + 60.97² )
= √ ( 1953.64 + 3717.34 )
= 75.3 m /s
Angle with horizontal Ф
TanФ = Vy / Vx
= 44.2 / 60.97
= .725
Ф = 36⁰ .

Consider a ball tossed from the ground into the air at 25 m/s. At a later time, the ball is measured to be moving downward at 11 m/s. a) Find how high the ball is off of the ground at the later time. b) Find the time interval between these two events. c) Sketch graphs of position, velocity, and acceleration versus time for the ball.
Answers
Answer:
The answer is below
Explanation:
a) According to Newton's law of motion, the distance travelled by a body going upward can be calculated using the formula:
v² = u² - 2gh
where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity and h is the height of the ball.
g = 10 m/s², u = 25 m/s, v = 11 m/s
Substituting:
11² = 25² - 2(10)h
20h = 25² - 11²
20h = 504
h = 25.2 m
b) The time (t) can be gotten using:
v = u - gt
Substituting
11 = 25 - 10t
10t = 25 - 11
10t = 14
t = 1.4 s
c) the graph were plotted using an online graphing tool

A train travels between two stations that are 63 km apart at an average speed of 35 m/s. How long after leaving the first station did the train arrive at the second station?
Answers
A train travels between two stations that are 63 km apart at an average speed of 35 m/s. Time taken by train after leaving the first station and arrive at the second station 1.8 sec.
What is speed?The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.
time = Distance / speed
= 63/35.
= 1.8 sec

If:
Now: (if, ΔT = T), Using the formula of the period of a wave, find the frequency:
Explanation: Your Welcome u.u
The frequency of this wave is approximately 1.697 Hz.
To find the frequency of a wave, we can use the formula:
frequency (f) = speed (v) / wavelength (λ)
Given:
Wavelength (λ) = 3.3 m
Speed (v) = 5.6 m/s
Substituting these values into the formula, we can calculate the frequency:
f = v / λ
f = 5.6 m/s / 3.3 m
f ≈ 1.697 Hz
Therefore, the frequency of this wave is approximately 1.697 Hz.

Answer:
When you are running the most important force that you should understand is friction. Friction is a force that opposes movement between two objects, but for runners friction makes you faster. Friction gives you a better and more efficient way to use your energy into speed.
