Explanation:
The energy of a wave is given by :
[tex]E=\dfrac{hc}{\lambda}[/tex]
Where
h is Planck's constant
c is the speed of light
[tex]\lambda[/tex] is wavelength
Energy is inversely proportional to wavelength. Also, the relation between frequency and wavelength is inverse.
If the frequency is high, the wavelength will be shorter.
Hence, the correct options are :
Higher frequencies have shorter wavelengths.
Shorter wavelengths have lower energy.
Lower frequencies have lower energy.

Minute after minute, hour after hour, day after day, ocean waves continue to splash onto the shore. Explain why the beach is not completely submerged and why the middle of the ocean has not yet been depleted of its water supply. A) Ocean waves can only bring water to the shore but cannot take it back. The momentum of the water particles switches direction when the wave hits the shore and this momentum takes all the water back into the ocean. B) Ocean waves bring the water and also take it all the way back into the ocean. As such, water does not pile up on the beach. C) Ocean waves can only bring energy to the shore; the particles of the medium (water) simply oscillate about their fixed position. D) None of the choices are correct.
Answers
Answer: C. Ocean waves can only bring energy to the shore; the particles of the medium (water) simply oscillate about their fixed position.
Explanation:
The reason why the beach is not completely submerged and the reason why the middle of the ocean has not been depleted of its water supply is due to the fact that water isn't transported by ocean waves.
It should be noted that even a single drop of water cannot be brought by the ocean wave to the shore from the middle of the ocean.
The only thing that the ocean waves can bring to the shore is energy. Hemce, the water particles oscillate in their fixed position which is vital in making sure that the beach isn't piled up with water.
What is a wave's speed if it has a wavelength of 3.2x10^-7 m and a period of 2.8x10^-12s
Answers
Answer: 1.1·10^5 m/s
Explanation: speed = wavelength · frequency v = λf and
frequency f = 1/T , in which T = period
Speed v= λ/T = 3.2·10^-7 m /2.8·10^-12 s = 114285,7 m/s

how does the value of the electrostatic force vary with the distance between them?
Answers
A body is moving with a velocity of 15m/s . If the motion is uniform. How much distance will be the velocity after 10s
Answers
Answer:
Distance = 150 meters.
Explanation:
Given the following data;
Velocity = 15 m/s
Time = 10 seconds
To find the distance;
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
[tex]Velocity = \frac{distance}{time}[/tex]
Making distance the subject of formula, we have;
[tex] Distance = velocity * time [/tex]
[tex] Distance = 15 * 10 [/tex]
Distance = 150 meters

Hey Why you wrote my name hn?
describe how you would determine the half-life of a substance from an activity/time graph, plsplspls help
Answers
Answer: At any time, the number of decays per reasonable
time unit is proportional to the amount of the isotope present. (This is expressed by the first-order rate equation for a one-decay process.) Therefore, it does not matter whether one looks at the amount or the number of decays. It may be easier to measure the number of decays by e.g. a Geiger counter and prefer it for that reason.
It now matters what you understand to be the rate: the number of decays per second or the percentage of nuclei decaying at any given time. The first becomes less over time, the second one is a constant for each isotope.
You must have a reasonable number of decays within your time unit. If the half-life is long, it makes little sense to look at millisecond slices.

According to Newton’s second law, the mass of an object is 120kg and it is accelerating at a rate of 5m/s2 . The object’s force would be
Answers
Answer:
F = 600 N
Explanation:
The second law is F = m * a
The mass (m) is in kg = 120
The acceleration in in m/s^2 = 5
The force is in Newtons.
m and a do not require any conversions. They are in the correct units.
F = 120 * 5
F = 600 N

If it takes 726 watts of power to move an object 36 m in 14 s, what is the mass of the object?
Answers
Answer:
Explanation:
Given
Power (p)= 726 watt
Time (t) = 14 sec
distance travelled (d; h) = 36 m
mass (m) = ?
we know
Power (p) = W/t ( w = work done )
p = m * g * h / t ( w = m * g* h)
726 = m * 10 * 36 / 14 ( g = 10 m/s^2)
m = 28. 23 kg
or if we use the value of g as 9.8 m/s^2
the mass will be
= 28.8 kg
hope it helps :)
The mass of the object if it takes 726 watts of power to move an object 36 m in 14 s is 28.8 kg.
What is mass?An object's inertia, a fundamental property, is measured by its mass, a fundamental indicator of the volume of substance inside the thing. Definitions of mass can seem circular since it is such a fundamental quantity and is challenging to define in terms of another.
It is possible to define every mechanical quantity in terms of mass, length, and time. The SI unit for mass, denoted by the letter m, is the kilogram. While mass is typically thought of as an immutable feature of an item, relativistic mass must be taken into account when traveling at speeds close to the speed of light.
Given:
The Power, p = 726 watt
The Time, t = 14 sec
distance travelled, d = 36 m
Calculate the power by the given formula
p = W / t
p = m * g * h / t ( w = m * g* h)
726 = m * 9.8 * 36 / 14 ( g = 10 m/s^2)
m = 28. 8 kg
Therefore, the mass of the object If it takes 726 watts of power to move an object 36 m in 14 s is 28.8 kg.

A pump is to lift 20.0 kg of water per minute through a height of 25.50 m. What output rating should the pump motor have?
Answers
Answer:
the output rating that should the pump motor have is 83.30 Watt
Explanation:
Given that
The pump lift 20 kg of water per minute having a height of 25.50 m
We need to find out the output rating that should the pump motor have
As we know that
power = energy ÷ time
= m g h ÷ t
= 20.0 × 9.8 × 25.50 ÷ 60
= 83.30 Watts
Hence, the output rating that should the pump motor have is 83.30 Watt
