Answer: The lead is more dense :)
Explanation:
Answer:
Explanation:
Particles of a solid are closely packed, and when a solid is hit to produce a sound the kinetic energy present in the solid will cause the particles to vibrate vigorously in the intermolecular spaces in the solid, whereas the paticles of liquids and gases are rather further apart therefore having large intermolecular spaces between particles.
Answer:
radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
Explanation:
Electromagnetic waves are the waves which are created as the result of the electrical waves which are perpendicular to each other and also perpendicular to the direction of propagation.
Electromagnetic spectrum is range of the frequencies and their respective wavelengths of the various type of the electromagnetic radiation.
In order of the increasing frequency and the photon energy and the decreasing wavelength the spectrum are:
<u>radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays</u>.
Answer:
a) Angular speed(w) = 2.02rad/sec
b) 73J ( It is Inelastic Collision)
Explanation:
Given:
Mass=45kg
Length on each side = 1.5m side which is hangs vertically from a frictionless pivot at the center of its upper edge.
We need to calculate
(a) What is the angular speed and
(b) To know why the angular momentum conserved but not the linear momentum
