Please help, it’s the last question and I’m bad at Physics
Answer:
The end velocity of the sculpture is 7.00 m/s²
Explanation
The equation needed here is v = √(2gh). Let's do it:
v = √(2 × 9.8m/s² × 2.5m)
v = √(49.0 m²/s²)
v = 7.0m/s
Funny enough the numbers given don't have the accuracy demanded. We're given is 2.5m which is only accurate to the tenths, and 30kg which is only accurate to the nearest integer. Also, presumably the acceleration due to Earth gravity that's provided is only 9.8m/s², so that's still only the nearest tenth. So taking those and asking to find the answer to the nearest hundredth is pointless.
But whatever. The given answer is correct to the nearest hundredth. 7.00m/s² To be sure, I plugged it into a form on a physics page that does exactly that, and the answer they gave was 7.0023745972349, so we have it rounded correctly.

Which of these is not a standard unit?
a. second
b. metre
c. hand span
d. gram
Answer: Hand span
Explanation: Hand span is not a standard unit.
Second is the unit of time.
Meter is the unit of length or distance covered by an object.
Gram is the unit of weight of an object.
Hand span is not a standard unit. This is because the size of hand varies from person to person. Hence, the correct option is (c) "hand span".

how are electromagnetic waves produced
Answer:
Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.
Answer: Electromagnetic waves are the combination of electric and magnetic field waves produced by moving charges.
The creation of all electromagnetic waves begins with a charged particle. This charged particle creates an electric field (which can exert a force on other nearby charged particles). When it accelerates as part of an oscillatory motion, the charged particle creates ripples, or oscillations, in its electric field, and also produces a magnetic field (as predicted by Maxwell’s equations).
Once in motion, the electric and magnetic fields created by a charged particle are self-perpetuating—time-dependent changes in one field (electric or magnetic) produce the other. Both electric and magnetic fields in an electromagnetic wave will fluctuate in time, one causing the other to change.
Electromagnetic waves (photons) are produced anytime a charged particle experiences a change in velocity.. The electromagnetic wave (radiation) that is produced when the charge particle changes it’s velocity is how energy is conserved. This energy is light.

What differentiates one layer of the atmosphere from one another?
Please help
Answer: The stratosphere and the troposphere are defined by the variation in temperature with height. Within a troposphere, the temperature drops as altitude increases, and drops fast enough for convection to occur. Whereas within a stratosphere, the temperature rises with increasing altitude. Features of the atmosphere change with altitude: density decreases, air pressure decreases, temperature changes vary. Different temperature gradients create different layers within the atmosphere. The lowest layer is the troposphere where most of the atmospheric gases and all of the planet's weather are located.

Explanation:
A sodium vapor lamp omit waves with the frequency of 5.26x10^14 Hz. What is the wavelength of light?
Answer:
[tex]\lambda=5.70\times 10^{-7}\ m[/tex]
Explanation:
The frequency of a sodium vapor lamp, [tex]f=5.26\times 10^{14}\ Hz[/tex]
We need to find the wavelength of light. The relation between wavelength, frequency and speed of light is given by :
[tex]c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{5.26\times 10^{14}}\\\\\lambda=5.70\times 10^{-7}\ m[/tex]
So, the wavelength of light is equal to [tex]5.70\times 10^{-7}\ m[/tex].
A layer of ethyl alcohol (n= 1.361) is on top of the water ( n=1.333) . At what angle relative to the normal to the interface of the two liquids is light totally reflected
Answer:
78.35°
Explanation:
THIS IS THE COMPLETE QUESTION BELOW;
A layer of ethyl alcohol (n = 1.361) is on top of water (n = 1.333). To the nearest degree, at what angle relative to the normal to the interface of the two liquids is light totally reflected?
From Snell's Law,
(ni)/(nr) = Sin (θr) / Sin (θi)
Where
θi = Angle of Incidence
θr = Angle of refraction
ni = Refractive index given for ethyl alcohol
nr = Refractive index of medium from which light is refracted
ni = 1.361
nr = 1.333
, θr = 90° ( Critical Angle is reffered to as Angle of Incidence at refracted angle of 90°) (θi = θc)
(ni)/(nr) = Sin (θr) / Sin (θi)
1.361/ 1.333 = Sin (90°)/ Sin( θc)
1.021= 0.894/ Sin( θc)
Sin( θc)= (0.9794
θc = Sin⁻¹ 0.9794)
θc = 78.35°
Which of the following accurately describes how scientists use models?
A. To make science seem more complex and inaccessible
B. To take measurements of an object, process, or system as it is in
nature
C. To make direct observations of a natural object, process, or
system
D. To represent objects, processes, and systems that are too large,
too small, or too complex to study directly
Answer:
D
Explanation:
To represent objects, processes, and systems that are too large, too small, or too complex to study directly
The correct option is (d) To represent objects, processes, and systems that are too large, too small, or too complex to study directly.
Scientists employ models to comprehend phenomena they are unable to directly observe. Models aid scientists in their understanding of phenomena, no matter how big or little they may be, such as the universe or an atom. Additionally, they can aid in their understanding of systems like weather patterns.In a range of scientific disciplines, from physics and chemistry to ecology and the Earth sciences, scientific models are employed to explain and forecast the behavior of real things or systems.Models can aid in scientific prediction, understanding of processes, and communication of ideas.

PLEASE HELP I HAVE FINALSSS
Answer: 26.67 m/s
Explanation:
Given
Length traveled by the ball [tex]s=40\ m[/tex]
Time taken to reach the goal post is [tex]t=3\ s[/tex]
Initial velocity [tex]u=0\ m/s[/tex]
Using the second equation of motion
[tex]\Rightarrow s=ut+\frac{1}{2}at^2\\\Rightarrow 40=0+\frac{1}{2}a(3)^2\\\Rightarrow a=\frac{80}{9}\ m/s^2\\[/tex]
Now using
[tex]\Rightarrow v^2-u^2=2as\\\\\Rightarrow v^2-0=2\times \frac{80}{9}\times 40\\\\\Rightarrow v=\sqrt{\dfrac{80\times 80}{9}}=\dfrac{80}{3}\\\Rightarrow v=26.67\ m/s[/tex]
The velocity of ball will be 26.67 m/s

Radon-220 is a radioactive gas. It escapes from underground rocks and causes a large part of the natural background radiation in the United Kingdom. It has an atomic number of 86. How many neutrons are there in its nucleus?
Answer: 134 neutrons are there in the nucleus of Radon-220
Explanation:
Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.
Thus, number of protons = atomic number = 86
Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.
Mass number = Number of protons + Number of neutrons
220 = 86 + Number of neutrons
Number of neutrons = 134

How fast is a skydiver going after 5 seconds or free fall and how far did he fall
Answer:
It's typically around 120mph. You'll reach this speed a few seconds into your jump, so for those few moments straight out the door, you'll be falling a bit more slowly and therefore covering less distance. We usually estimate around 10 seconds for the first 1,000 feet, then 5 seconds for each 1,000 feet after that.
