Answer:
• As heat is applied to one end of this material, atoms in the hotter region gain vibr à tory energy at a maximum amplitude . They transfer it on to their neighboring atoms and heat is transfered along this material in form of vibràtory energy.

Answer:
vcyl / vsph = 1.05
Explanation:
The kinetic energy of a rolling object can be expressed as the sum of a translational kinetic energy plus a rotational kinetic energy. The traslational part can be written as follows:
The rotational part can be expressed as follows:
where I = moment of Inertia regarding the axis of rotation. ω = angular speed of the rotating object. If the object has a radius R, and it rolls without slipping, there is a fixed relationship between the linear and angular speed, as follows:
For a solid cylinder, I = M*R²/2 (4) Replacing (3) and (4) in (2), we get:
Adding (5) and (1), we get the total kinetic energy for the solid cylinder, as follows:
Repeating the same steps for the spherical shell:
Since we know that both masses are equal each other, we can simplify (6) and (9), cancelling both masses out. And since we also know that both objects have the same kinetic energy, this means that (6) are (9) are equal each other. Rearranging, and taking square roots on both sides, we get:
This means that the solid cylinder is 5% faster than the spherical shell, which is due to the larger moment of inertia for the shell.
Answer:
L = 4.711 *10^{-6} kg m2/s
Explanation:
=4.5*10^-5
angular velocity
= 0.1047 rad/s
the angular momentum,
It is B. false that an instrument used to detect a static electric charge is called an ammeter. It is actually called an electroscope. Ammeter measures current.
Answer:
Explanation:
Given
same charge on both masses
potential Energy due to Magnetic Field =Kinetic Energy of Particle
and we know
Force due to magnetic field will Provide centripetal Force
and B is equal for both particles
thus
