The maximum height is 4.33m from which a person can jump rigidly without breaking any bones.
We have some data like bone maximum bearable energy is 3000J.Also,mass of person is 70kg.We know that a person cannot be broken until person jump from that height where the potential energy of person due to its position is greater than the bone energy.
It means that we need to equate or potential of person with the bone energy.
We know that potential energy of person is given by =mgh where m is the mass of the body, g is acceleration due to gravity and h is the height of the body.
Therefore, potential energy is =m × g × h
=>potential energy=70×9.8×h---------(eq1)
Now, we have bone energy =3000J -----(eq2)
Equate both equations,we get
=>70×9.8×h=3000
=>h=(3000/(70×9.8)
=>h=3000/686
=>h=4.33m
Hence, maximum height is 4.33m.

calculate the velocity of a non-relativistic electron whose de broglie wavelength is 3.637 nm.
Answer:
The velocity of a non-relativistic electron can be calculated using the formula v = h / mλ, where h is Planck's constant, m is the mass of the electron, and λ is the de Broglie wavelength of the electron.
Assuming the mass of the electron is 9.11 x 10^-31 kg, the velocity of the electron can be calculated as follows:
v = (6.63 x 10^-34 m^2 kg / s) / (9.11 x 10^-31 kg * 3.637 x 10^-9 m)
This works out to be approximately 5.82 x 10^6 m/s.
However, it's important to note that the de Broglie wavelength of a particle is generally only considered to be a meaningful quantity when the particle is moving at speeds that are comparable to the speed of light. For non-relativistic particles, such as an electron moving at a low velocity, the de Broglie wavelength is not a well-defined concept. Therefore, it's not meaningful to calculate the velocity of an electron based on its de Broglie wavelength.
Explanation:
Answer: 2 x 10^5 m/s
Explanation:
de Broglie wavelength equation: λ = h / mv
v = h / m · λ
m = 9.11 x 10^-31 kg
h = 6.62 x 10^-34 J·s
λ = 3.637 x 10^-9 m
v = (6.62 x 10^-34 J·s) / (9.11 x 10^-31 kg) (3.637 x 10^-9 m)
v = 199800.3807 = 2 x 10^5 m/s

The average kinetic energy of molecules of an ideal gas doubles if the _______ doubles.
The average kinetic energy of molecules of an ideal gas doubles if the temperature doubles.
Kinetic theory of gases says that the molecules of gas are in random motion and are continuously colliding with each other and with the walls of the container. All the collisions involved are elastic in nature due to which the total kinetic energy and the total momentum both are conserved. No energy is lost or gained from collisions.In an ideal gas, there are no attractive forces between the gas molecules, and there is no rotation or vibration within the molecules.The kinetic energy of the translational motion of an ideal gas depends on its temperature. The formula for the kinetic energy of a gas defines the average kinetic energy per molecule.

The angular speed increases by a factor of 2 and when she decreases her moment of inertia by a factor of 2 her angular speed change.
Angular momentum is a characteristic of rotating bodies determined by the product of their angular velocity and moment of inertia.
Angular momentum = Angular velocity x Moment of inertiaThe angular momentum is calculated by

The electric field strength between the plates is 7857 volts per meter.
Whatever place in space where a charge, in any form, exists has an electric property associated with it. This property is known as the electric field. Another metric for describing an electric field is the electric force per unit charge.
The most frequent causes of electric fields are shifting magnetic fields or electric charges. The SI unit volt per meter (V/m) is used to express the strength of an electric field.
The force operating on the positive charge is thought to be acting in the direction of the field. From a positive charge, the electric field radiates radially outward; from a negative charge, it radiates radially inward.
Between two uniform conducting plates, the size of the electric field is represented as
E = V/d
While d stands for the space between the plates, V represents the potential difference between them.
Potential is 550 V at a distance of 7 cm from the plate with zero volts (and 3.00 cm from the other).
Consequently, when we change the variables in the equation above, we get
E = 550V/ (7* 10⁻²m)
E = 78.57 * 10² V/m
As a result, the electric field strength between the plates is 7857 volts per meter.

a photoelectric-effect experiment finds a stopping potential of 1.93 v when light of 200 nm is used to illuminate the cathode.
When the frequency of the light is increased, the stopping potential also increases. In your case, the stopping potential for a light of wavelength 200 nm is 1.93 V.
The Relationship Between Light Frequency and Stopping Potential in the Photoelectric Effect ExperimentThe photoelectric effect is the phenomenon in which electrons are emitted from a surface when exposed to light. In a photoelectric effect experiment, the stopping potential is the minimum voltage required to stop the electrons from being emitted. The stopping potential increases as the frequency of the light increases.
In this experiment, a light of wavelength 200 nm was used to illuminate the cathode, and the stopping potential was found to be 1.93 V. This indicates that the frequency of the light was just high enough to cause the electrons to be emitted, but not high enough to cause a larger potential to be required to stop the electrons. Therefore, if the frequency of the light increases, the stopping potential will also increase.

Presently, we perceive how parallax estimations can be utilized to decide the distances, one of the realities we know is that if we have any desire to gauge the distance of divine bodies, we are familiar with the parallax, first and foremost, point. That's what it intends assuming we can quantify tiny parallax points, we can gauge enormous distances moreover.
The purpose for why we can not make precise estimations of parallax past a specific distance is that as the distance of the star from earth builds the parallax point turns out to be tiny.
Subsequently, presently we comprehend how parallax estimations are utilized.

a transformer has an output current of 2 a and an input current of 2 a. if the input coil has 238 loops, how many loops are in the output coil?
The number of loops in the output coil are 238 loops.
In a step-up transformer, the relationship between the number of turns in its primary coil Np, the number of turns in its secondary coil Ns, the input voltage Vp, the output voltage Vs, the input current Ip and the output current Is is given by:
Ns/Np = Vs/Vp = Ip/Is
Now, we need the relation between number of loops and current:
Ns/Np = Ip/Is
Given that, Np = 238 loops
Ns = ?
Ip = 2 A
Is = 2 A
Now, let us put the values in the above relation.
Ns = Ip/Is * Np = 2/2 * 238 = 238 loops
Thus, number of loops in output coil are 238 loops.

Cherise sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Cherise can move the carts one space to the left or one space to the right. Which movement will result in the largest increase in potential energy?.
If you want to maximize your potential energy, you can move the cart in any direction and get the same outcome because the distance it travels in each direction is equal.
The energy that a body possesses in its resting state is called its potential energy. The energy of a moving object is known as its kinetic energy. Stored energy that is conditional on the spatial orientation of the system's components; is also known as potential energy.
When a spring is either squeezed or stretched, the resulting increase in potential energy can be used to do work. Potentially, a steel ball has more energy in the air than it does when it hits the ground.
Here, we can observe that the carts are shifted to the right or left by one space. Consequently, the potential energy will also change in response to the motions.
