73.5 kilojoules are the answer. Since we can compute potential energy, we can convert 250 into 9.8 into 30 into 73500 joules, or u equal to m g h. Consequently, the body's potential energy will be 73500 joules, which is the necessary amount.
This potential energy calculator allows us to calculate the amount of energy that an elevated object has stored inside it. The full name of this effect is gravitational potential energy, and it refers to the energy that an item stores as a result of its height or vertical position.
The great wrecking ball of the crane. The ball's gravitational potential energy depends on both its mass and how high it is elevated. The relationship between gravitational potential energy and an object's mass and height is seen in the following equation:
PE Gravity equals (m, h, and g). The formula is rather simple to comprehend. The height of a non-raised object will be zero, and as a result, it will have no potential energy.

Zsm-5, a catalyst material, has a surface area of 425 m^2/g. what is the surface area of this material in cm^2/mg?
The surface area of the material in cm²/mg is 4250 cm²/mg
How to convert 425 m²/g to cm²/gWe'll begin by converting 425 m²/g to cm²/g. This can be obtained as follow:
1 m²/g = 10000 cm²/g
Therefore,
425 m²/g = (425 m²/g × 10000 cm²/g) / 1 m²/g
425 m²/g = 4250000 cm²/g
How to convert 4250000 cm²/g to cm²/mgWe can convert 4250000 cm²/g to cm²/mg as follow:
1000 cm²/g = 1 cm²/mg
Therefore,
4250000 cm²/g = (4250000 cm²/g × 1 cm²/mg) / 1000 cm²/g
4250000 cm²/g = 4250 cm²/mg

true or false: it is possible for an object to nnove for 10 seconds at a high speed and end up with an average velocity of zero.
Yes. it is possible for an object to move for 10 seconds at a high speed and end up with an average velocity of zero.
What is average velocity?Velocity is answer to the question: How fast are you changing your position? It's basically asking for a comparison of where you are at two different times and makes rate of change quantitative. To make sense out of this, let's first write it as words equation:
The average velocity = (How far did you move?) / (How long did it take you?)
That way, doing either a bigger distance in the same time or the same distance in a shorter time both give a larger number to velocity and agree with our sense of what it means to move faster.
For the above question:
Average velocity is displacement over the time. Displacement is difference between your final position and your initial position. If you traveled in circular path, very fast, or very slow, and ended up back where you started, your displacement would be zero. Dividing your displacement of zero, by time your trip took, will give you an average velocity of zero.

It concludes that the "CO2 fertilizations effect," a process wherein rising CO2 levels in the atmosphere boost the growth and, consequently, carbon uptake of plants, would likely cause an increase in the pace at which land absorbs carbon until the second part of this century.

Mass = 0.1g
Charged excess electrons = 1×10¹⁰
What is the Electric field?The Electric field can be defined as the ratio of the electric force per unit charge.
So, the working equation for this is,
E = F/Q,
where E is the strength of electric field, F is the force and Q is the charge.
The force is equal to:
F = mg = (0.1/1000 kg)(9.81 m/s²) = 0.981 ×10⁻³ N
The charge of the excess electrons is equal to:
Q = (-1.6021766208×10⁻¹⁹ C/electron)(1×10¹⁰ electrons)
Q = -1.6021766208×10⁻⁹ C
E = 0.981 ×10⁻³ N/-1.6021766208×10⁻⁹ C
E = -612292.045 N/C
Thus, the electric field that cause the bead to hang suspended in the air is calculated as E = -612292.045 N/C

the g string on a guitar is a 0.44-mm-diameter steel string with a linear density of 1.1 g/m . when the string is properly tuned to 196 hz, the wave speed on the string is 250 m/s. tuning is done by turning the tuning screw, which slowly tightens-and stretches-the string.
The G string on a guitar stretches by 1.696 mm when it is first tuned by using the formula of young's modulus.
Expression for the velocity of the waves on the stretched string
ν = √T/μ
Where, T = tension on the string
250 =√T/ 1.1 × 10⁻³
T = 68.75 N
The young modulus of the steel is given by
Y = 200 × 10⁹ Pa
Y = (T/A)/(Δl/l)
Δl = Tl/AY
By putting the values, we get,
Δl = 68.75 × 0.75/ 200 × 10⁹ × π × (0.22 × 10⁻³)²
Δl = 1.696 × 10⁻³m
Or, Δl = 1.696 mm
Hence, by 1.696 mm, the G string stretch when it is first tuned.

What is electromagnetic wave?When a magnetic field and an electric field interact, electromagnetic waves are created. An electromagnetic wave has an electric field and a magnetic field that are perpendicular to one another.
The parts of the electromagnetic spectrum are designated as follows, from highest to lowest energy: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. The radio wave region of the electromagnetic spectrum includes microwaves (such as those found in microwave ovens).
An electromagnetic wave first encounters the atoms of a physical substance, which absorb the radiation. Vibrations. The electrons inside of this atom begin vibrating as a result of the absorption of this electromagnetic energy.

If a glass has an index of refraction, n = 1.52, what is the speed of light inside the glass? show calculations with equation and numbers plugged in.
If a glass has an index of refraction, n = 1.52,
The speed of light inside the glass will be [tex]1.97\times10^8m/s[/tex].
How to find the refractive index?
To find the refractive index of a material, following formula is used:
Refractive index = Speed of light in air / Speed of light in the crown glass
We are given the value of refractive index is 1.52.
We know that the speed of light is [tex]3\times10^8m/s[/tex].
We will substitute the numerical values in the formula, we get:
[tex]1.52=\frac{3\times10^8m/s}{\text{ Speed of light in crown glass} \text}\\[/tex]
[tex]\text{ Speed of light in crown glass} \text=\frac{3\times10^8}{1.52}[/tex]
Hence, the speed of light inside the glass will be [tex]1.97\times10^8m/s[/tex].
