We now have two tappers that are tapping the surface of the water together. They are tapping in sync (both are hitting the surface at the same time). A small cork is sitting in the tank at the position of the small brown circle. As the stars continue to tap and the ripples from each star continue to move outward, what will happen to the cork
Answer:
The cork moves up and down.
Explanation:
The cork moves up and down because of the waves produce due to tapping the surface of water. The cork experience movement due to placed on the water surface so when the wave passes through the medium by tapping of water, movement of cork also occur. Cork has high volume and lower mass so it floats on the water surface and experience movement due to waves.

In 1940, it was discovered that uranium could be artificially changed to plutonium, a process called transmutation. What combination of decay processes would convert U-239 (92 protons) into Pu-239 (94 protons)?
A. Beta-decay followed by beta decay.
B. Positron emission followed by electron capture.
C. Electron capture followed by alpha decay.
D. Alpha decay followed by beta decay.
The combination of decay processes that would convert U-239 into PU- 239 is beta decay followed by another beta decay. There are two different types of beta decay (positive and negative beta decays) they both occur simultaneously in order to move the atoms towards stability.
Light of wavelength 500 nm illuminates parallel slits and produces an interference pattern on a screen that is 1 m from the slits. In terms of the initial intensity I0, the light's intensity in the interference pattern at a point for which the path difference is 300 nm is
Answer:
this point we have a destructive inference m=1
Explanation:
This is an interference exercise, where the light has two possible states one of constrictive interference
d sin θ = m λ
and another of destructive interference
d sin θ = (m + ½) λ
the term on the left is the difference in trajectory that tells us that it is worth
d sin θ = 300 nm = 300 10⁻⁹ m
We can find what type of interference we have by finding m, which must be an integer
constructive interference
m = d sin θ /λ
let's calculate
m = 300 10⁻⁹ / 500 10⁻⁹
m = 0.6
this value is not possible because m must be an integer
destructive interference
m + ½ = d sin θ /λ
m = d sin θ /λ + ½
m = 0.6 + 0.5
m = 1.1
that can be approximated to m = 1
this value if possible, so at this point we have a destructive inference

If you exert 950 N*s of impulse on a 12 kg frictionless cart over the course of 5 seconds, how far will it travel during those seconds?
Answer:
The value is [tex]s =197.88 \ m[/tex]
Explanation:
From the question we are told that
The impulse is [tex]I = 950 \ N\cdot s[/tex]
The mass is [tex]m = 12 \ kg[/tex]
The time t = 5 s
Generally impulse is mathematically represented as
[tex]I = F * t[/tex]
=> [tex]F = \frac{I}{t}[/tex]
=> [tex]F = \frac{950 }{ 5 }[/tex]
=> [tex]F = 190 \ N[/tex]
Generally force is mathematically represented as
[tex]F = m * a[/tex]
=> [tex]a = \frac{F }{ m }[/tex]
=> [tex]a = \frac{190 }{ 12 }[/tex]
=> [tex]a = 15.83 \ m/s^2[/tex]
Generally from kinematic equation , the distance covered is
[tex]s = ut + \frac{1}{2} * at^2[/tex]
Here u is the initial velocity of the cart and the value is [tex]u = m/s[/tex]
=> [tex]s = 0 * 5 + \frac{1}{2} * 15.83 * 5^2[/tex]
=> [tex]s =197.88 \ m[/tex]

Is ionic or covalent
Answer:
it is a ionic bond because electrons are transferred from chlorine to strontium
Strontium chloride, SrCl₂, is an ionic compound because Ionic compounds are formed through the transfer of electrons from one atom to another, resulting in the formation of positively charged ions (cations) and negatively charged ions (anions).
In the case of strontium chloride, strontium (Sr) is a metal, and chlorine (Cl) is a non-metal. Strontium readily donates two valence electrons to chlorine, which has a strong affinity for gaining one electron to achieve a stable electron configuration. The electron transfer between strontium and chlorine leads to the formation of S[tex]r^2^+[/tex] cations and C[tex]l^-[/tex] anions. The resulting ionic bond holds the cations and anions together in a crystal lattice structure. The attraction between the oppositely charged ions creates the ionic bond, making strontium chloride an ionic compound.

How is the pressure of a gas related to its concentration of particles?
Answer:
Explanation:
Pressure will expand a gas, enlarging its volume and reducing its density and concentration of particles. Pressure will magnify a gas, developing its volume and multiplying its density and concentration of particles.
Increasing the pressure of a gas is exactly the same as increasing its concentration. If you have a given mass of gas, the way you increase its pressure is to squeeze it into a smaller volume. If you have the same mass in a smaller volume, then its concentration is higher.

The maker of an automobile advertises that it takes 13 seconds to accelerate from 5 kilometers per hour to 65 kilometers per hour. Assuming constant acceleration, compute the acceleration in meters per second per second. Round your answer to three decimal places.
Answer: the acceleration is 1.282 m/s²
Explanation:
Given that;
Time t = 13 sec
Initial velocity U = 5 kmph = (5 × 1000)/(60 × 60) = 1.3888 m/s
final velocity V = 65 kmph = (65 × 1000)/(60 × 60) = 18.0555 m/s
Now we know that;
V = U + at
we substitute
18.0555 = 1.3888 + 13a
18.0555 - 1.3888 = 13a
13a = 16.6667
a = 16.6667 / 13
a = 1.282 m/s²
Therefore the acceleration is 1.282 m/s²

A fire truck emits an 880Hz siren. As the truck approaches an observer on the sidewalk, he perceives the pitch to be 950Hz. Approximately what pitch does he hear after the truck passes and is moving away?
Answer:
The pitch that he hears after the truck passes and is moving away is 819.6 Hz.
Explanation:
The pitch that he hears after the truck passes and is moving away can be calculated using the following equation:
[tex] f = f_{0}*\frac{v_{s} \pm v_{o}}{v_{s} \pm v_{f}} [/tex]
Where:
[tex]f[/tex]: is the perceived frequency
[tex]f_{0}[/tex]: is the emitted frequency
[tex]v_{s}[/tex]: is the speed of sound = 340 m/s
[tex]v_{o}[/tex]: is the speed of the observer = 0 (he is not moving)
[tex]v_{f}[/tex]: is the speed of the fire truck
First, we need to find the speed of the fire truck. When it approaches the observer we have:
[tex] f = f_{0}*\frac{v_{s} + v_{o}}{v_{s} - v_{f}} [/tex]
[tex] 950 Hz = 880 Hz*\frac{340 m/s}{340 m/s - v_{f}} [/tex]
[tex] v_{f} = 340 m/s - \frac{880 Hz*340 m/s}{950 Hz} [/tex]
[tex] v_{f} = 25.05 m/s [/tex]
Hence, the speed of the fire truck is 25.05 m/s.
Now, we can calculate the pitch that the observer hears after the truck passes:
[tex] f = f_{0}*\frac{v_{s} - v_{o}}{v_{s} + v_{f}} [/tex]
[tex] f = 880 Hz*\frac{340 m/s}{340 m/s + 25.05 m/s} [/tex]
[tex] f = 819.6 Hz [/tex]
Therefore, the pitch that he hears after the truck passes and is moving away is 819.6 Hz.
