TRUE/FALSE. a planet orbiting another star is made primarily of hydrogen and helium and has approximately the same mass as jupiter but is the same size as neptune.
A planet orbiting another star is made primarily of hydrogen and helium and has approximately the same mass as jupiter but is the same size as neptune. This statement is false.
The given statement is false, because this statement is contradictory. Hydrogen-helium planet would have to be more gravitationally compressed in order to be smaller than Jupiter. So it would have to have a larger mass than Jupiter and also a planet with that size and mass would be too dense to be made of helium and hydrogen.

solid conductor with radius a is supported by insulating disks on the axis of a conducting tube with inner radius bb and outer radius cc ((figure 1)). the central conductor and tube carry currents i1i1 and i2i2 correspondingly in the same direction. the currents are distributed uniformly over the cross sections of each conductor. derive an expression for the magnitude of the magnetic field
We can determine the magnetic field over two different distances from a network made up of 2 conductors using Ampere's law:
The system's magnetic field is: B = μ₀.I/(2πr).
Explain the term Magnetic field region?The region of space close to an electric current, magnetism, or a moving charged object is called the magnetic field. Since it describes the direction and magnitude at each point, it is a vector field. At an intense magnetic field location, the magnetic field lines congregate there.According to Ampere's law, the magnetic field's dot product times a closed path equals proportional to the current that flows through the path.
∫ B. ds = μ₀ I
B is the magnetic field, S is the closed channel, m is the vacuum permittivity, and I is the current where bold indicates vectors;
For the magnetic fields within the two conductors.
Fixing the associated circular path will cause I, the current which stops inside the path, to flow through the system.
The circle's diameter is
s = 2π r.
B(2π r) = μ₀ I
B = μ₀.I/(2πr).
Thus, the expression for the magnitude of the magnetic field is found as

a 22 g bullet is accelerated in a rifle barrel 64.7 cm long to a speed of 953 m/s. use the work-energy theorem to find the average force exerted on the bullet while it is being accelerated. answer in units of n
A 22 g bullet is accelerated with a force of 1.5 × 10⁴ N. in a rifle barrel 64.7cm long to a speed of 953 m/s.
A 21 g (m) bullet is accelerated from rest (u= 0m/s) to 953 m/s (v). We have to calculate the change in the kinetic energy (∆K) using the following formula
∆K= Kf - Ki
where, Kf = final kinetic energy and Ki = initial kinetic energy
∆K= 1/2 x m x v² - 1/2 x m x u²
∆K= 1/2 x m x v²
∆K= 1/2 x 0.022kg x (953m/s)²
∆K = 9.9 × 10³ J
The bullet is accelerated in a 64.7 cm riffle barrel.
According to the work-energy theorem- the work done is equal to the change in the kinetic energy.
W = F×s
W= F × 0.647 = 9.990 × 10³ J

When the distance between the two bodies of same mass is halved the mutual force of attraction between them becomes?.

As indicated by Newton's law of attraction each article or body in the universe draws in every single item towards one another and that power of fascination is straight forwardly relative to the result of their masses and contrarily corresponding to the square of the distance between them.
The power of gravity between two articles will diminish as the distance between them increments. The two most significant elements influencing the gravitational power between two items are their mass and the distance between their focuses. As mass increments, so does the power of gravity, however an increment in distance mirrors a reverse proportionality, which makes that power decline dramatically.
