What happens as the frequency of a wave increases?
Answer:
The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
Explanation:
please mark me as brainliest thank you
The number of complete wavelengths in a given time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease.
what is frequency ?The frequency referred to the number of oscillation per unit time and it is used for defining the cyclic process like rotation, oscillation, wave etc.
The SI unit is denoted as Hertz and the symbol λ represents it where one hertz means the wave completed one cycle in one second.
The frequency explains the phenomenon of oscillatory and vibration like the mechanical vibration, sound signals, light, frequency waves etc. The “period” represented as the time required by the wave for one oscillation, i.e., it is inversely proportional to the frequency.

A bat emits a pulse of sound of wavelength 0.0085 m. Calculate the frequency of the sound.
Answer:
v = 4.0 10⁴ Hz
Explanation:
The bat emits sound in the air, so we can use the speed of sound in air
v = 344 m / s
also the expression that relates the wavelength and frequency with the speed of the wave
v = λ f
f = v / λ
let's calculate
v = 344/0.0085
v = 4.0 10⁴ Hz

How much thermal energy is absorbed by
1.00X102 g of ice at -20.0°C to become
water at 0.0°C?
Answer:
4202.4 J
Explanation:
The formula for calculating the heat absorbed by ice to melt into water is given by :
ΔH = Cp × m × Δ T -------where ;
Cp =specific heat of ice = 2.06 J/g° C
m= mass of ice = 102 g
ΔT = 0°C--20°C = 20°C
Thermal energy absorbed by the ice will be;
ΔH = Cp × m × Δ T
ΔH = 2.06 * 102 * 20
ΔH =4202.4 J

A child approaches a stop sign and applies the brakes to slow to a stop. If the bicycle and child were originally traveling at 9.00 m/s and the breaks cause a deceleration of magnitude 1.20 m/s^2, how long will it take the child to stop?
Answer:
7.5secs
Explanation:
Using the equation of motion
v = u + at
v is the final velocity = 0m/s
u is the initial velocity = 9m/s
a is the deceleration = -1.2m/s²
t is the required time
Substitute;
0 = 9 + 1.2(t)
-9 = -1.2t
t = -9/-1.2
t = 7.5secs
hence it takes the child 7.5secs to stop

During a spring tide, the high tides are very high and the low tides are very low. Why does this occur?
Image result for During a spring tide, the high tides are very high and the low tides are very low. Why does this occur?
In both cases, the gravitational pull of the sun is 'added' to the gravitational pull of the moon on Earth, causing the oceans to bulge a bit more than usual. This means that high tides are higher and low tides are lower than average. These are called 'spring tides. '

A dry cleaner throws a 22 kg bag of laundry onto a stationary 9 kg cart. The cart and bag begin moving at 3 m/s to the right. Find the velocity of the bag before the collision. (4.2 m/s)
Answer:
Vbag = 4.22 [m/s]
Explanation:
In order to solve this problem we must use the principle of conservation of momentum. Which tells us that the momentum of a system is preserved before and after a collision.
Let's take both movements (bag and cart) as positive, since they both move in the same direction. Now everything that happens before the collision will be taken to the left of the equation and after the collision to the right of the equal sign.
[tex](m_{bag}*v_{bag})=(m_{bag}+m_{cart})*v_{final}[/tex]
where:
mbag = mass of the bag = 22 [kg]
vbag = velocity of the bag [m/s]
mcart = mass of the cart = 9 [kg]
vfinal = mass of both bodies moving together = 3 [m/s]
Now replacing:
[tex](22*v_{bag})=(22+9)*3\\22*v_{bag}=93\\v_{bag}=4.22[m/s][/tex]

49. A 6.1-kg bowling ball is liſted 2.1 m to a shell. Find
the increase in the ball-Farth system's energy.
Answer:
125.5J
Explanation:
Given parameters:
Mass of the bowling ball = 6.1kg
Height of lifting = 2.1m
Unknown:
Increase in the ball energy = ?
Solution:
The ball has changed position by moving it from one point to another. So, it has acquired more potential energy.
Potential energy = mgh
m is the mass
g is the gravity
h is the height
Now insert the given parameters and solve;
Potential energy = 6.1 x 9.8 x 2.1 = 125.5J
how does the eye control the amount of light entering it?
Answer: Hello there
Explanation:
The colored part of the eye which helps regulate the amount of light entering the eye. When there is bright light, the iris closes the pupil to let in less light. And when there is low light, the iris opens up the pupil to let in more light. Focuses light rays onto the retina.
A woman does 236 J of work
dragging her trash can 24.4 m to
the curb, using a force of 18.9 N.
At what angle was her force
directed?
(Unit = degrees)
Answer:
The woman's force was directed 59.22⁰ to the horizontal.
Explanation:
Given;
work done by the woman, W = 236 J
distance through the load was moved, d = 24.4 m
applied force, F = 18.9 N
inclination of the force, = θ
The work done by the woman is calculated as;
W = Fdcosθ
[tex]cos \ \theta = \frac{W}{Fd} \\\\cos \ \theta = \frac{236 }{18.9 \times 24.4} \\\\cos \ \theta = 0.5118\\\\\theta = cos^{-1} ( 0.5118)\\\\\theta =59.22^0[/tex]
Therefore, the woman's force was directed 59.22⁰ to the horizontal.
Answer:
59.22⁰

A vat of ethyl alcohol expands
by 0.00823 m^3 when the
temperature is raised by 44.8°C.
What was the original volume of
the alcohol?
Ethyl Alcohol B = 1120 10-C-1
(Unit = m^3)
Answer: .164
Explanation:
1120x10^6 is the coefficient for ethyl alcohol b
(.00823)/(1120x10^-6)(44.8) which gives you your answer: 0.164 m^3
A vat of ethyl alcohol expands by 0.00823 m^3 when the temperature is raised by 44.8°C. The original volume of the alcohol is 0.164m³.
What is volume ?A measurement of three-dimensional space is volume. It is frequently expressed quantitatively using SI-derived units, as well as several imperial or US-standard units. Volume and the notion of length are connected.
The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.
A three-dimensional object's volume is the area it takes up, and it is expressed in cubic units. Cm3 and in3 are two examples of cubic units. The amount of matter in an item can be determined by its mass, on the other hand.
1120 x 10⁶ is the coefficient for ethyl alcohol b
= (.00823 ) / ( 1120 x 10⁻⁶) ( 44.8 )
= 0.164 m³
Thus, The original volume of the alcohol is 0.164m³.
