The answer is A Height and Mass
Gravitational potential energy depends on the strength of gravity; A. height and mass of the object.
Gravitational potential energy (G.P.E) can be defined as the energy possessed by a physical object or body due to its position (height) above planet Earth.
Hence, gravitational potential energy (G.P.E) is highly dependent on mass, height of an object or body and the acceleration due to gravity.
Mathematically, gravitational potential energy (G.P.E) is given by the formula;
[tex]GPE = mgh[/tex]
Where:
G.P.E is the gravitational potential energy. m is the mass of an object. g is the acceleration due to gravity. h is the height of an object.In conclusion, the three (3) main factors that gravitational potential energy (G.P.E) depends on are:
I. Strength of gravity.
II. Height.
III. Mass.

Which element is an inner transition metal?
uranium (U)
osmium (Os)
radium (Ra)
hafnium (Hf)
Answer:
Os
Explanation:
Atoms of different element can not have same atomic number because only same type of atoms combine to form element. Atoms belonging to different element can have different atomic number. Therefore, the correct option is option A.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same. Two or more than two atoms with different physical or chemical properties can not combine together to form an element.
Among all the given options, uranium (U) is an inner transition metal. Inner transition metal are the metals that belongs to f block of periodic table as their last electron goes into f subshell.

A sample of an element has a mass of 80.01g and a density of 2.70 g/cm3. How many significant figures does the mass have?
The mass has 4 significant figures
Further explanationRules for significant numbers
1. all non-zero numbers are significant numbers 2. a zero which is located between two non-zero numbers including a significant number 3. all zeros are located in the final row written behind the decimal point include significant number 4. zero decimal point is not significant numbera sample has mass = 80.01 g
a zero which is located between two non-zero numbers including a significant number, so the mass has 4 significant figures : 8,0,0 and 1

A sound wave has a frequency of 20 Hz and a wavelength of 100 m. What is speed of the wave
The speed of a wave can be calculated using this formula:
v = f x λ
Where:
v is the wave speed in metres per second, m/s
f is the frequency in hertz, Hz
λ (lambda) is the wavelength in metres, m
Calculation:
Given:
f = 20 Hz
λ = 100m
Using the equation:
v = f x λ
v = 20 x 100
v = 2000 m/s
Therfore, the speed of the wave is 2000 m/s
A sound wave has a wavelength of 100 m and a frequency of 20 Hz. The wave's speed is 2× 10^3 m/s.
assuming frequency = 20 Hz and wavelength = 100 m
utilized concept: v= = 20×100 = 2×10³ m/s
Why is frequency important?The frequency in physics is the quantity of waves passing a fixed location in a unit of time. It also indicates how many cycles or vibrations a body in periodic motion experiences in a given unit of time.
How would you define sound?A sort of energy created by vibrations is sound. The molecules of the air surrounding an item vibrate as a result.. These molecules vibrate because they collide with nearby molecules, which also vibrate as a result.

4)If light is acting like a particle, then what should you adjust in the simulation to
make faster-moving electrons leave the metal surface
Answer:
We can either increase the frequency of the light source or decrease the wavelength of the light source in the simulation
Explanation:
When light approaches or strike a metal surface, we can observe electrons coming out the metal surface. So, when a light wave hits a metal surface, it becomes protons; thus, we can either increase the frequency of the light source or decrease the wavelength of the light source in the simulation.
Thus, a higher energy photon will strike the electron, and the electrons tend to gain energy from the photons.
There are 55.0 g of neon gas in a 3.0 L cylinder, the pressure is 4.5 atm what is the temp of the gas
Answer:
60.9 Kelvin
Explanation: First, write out everything that you know. You are tring to find the temperature, so the temperature will be represented by x.
Pressure (P)= 4.5 atm
Volume (V)= 3L
Number of Moles (n)= ?
Gas Consant (R)= 0.0821, if the pressure is in atm, that means r is 0.0821
Temperature (T)= x
We don't have all the information we need to plug the values into the equation. We still need to know how many moles 55.0 grans of neon is.
Ne in Grams= 55
Atomic Mass of Ne= 20.1797
55/20.1797= 2.7
moles= 2.7
Now that we have all the information we need, plug everying into the equation. In case you don't know, the Ideal Gas Law Equation is PV= nRT.
(4.5)(3) = (2.7)(0.821)x
x= 60.9
Now you have your temperature! It is 60.9 in Kelvin.

A yacht sailed at a steady speed for 0.5 hours, passing a cruise ship that was traveling at 25
kilometers per hour. During that time, the yacht traveled 50 kilometers. What was the yacht's
speed?
Write your answer as a whole number.
kilometers per hour
Submit
The speed of the yacht : 100 km/h
Further explanationLinear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration
At constant velocity motion:the speed of vo = v = constant
acceleration = a = 0
Δx = vt or x = xo + vt
An equation of constant velocity motion
[tex]\large {\boxed {\bold {x = v \times \: t}}}[/tex]
x = distance = m
v = speed = m / s
t = time = seconds
A yacht sailed at a steady speed for 0.5 hours, and traveled 50 kilometers
so the velocity/speed:
[tex]\tt v=\dfrac{x}{t}\\\\v=\dfrac{50~km}{0.5~h}=\boxed{\bold{100~km/h}}[/tex]
