Is the distance between two adjacent Antinodes?
Is the distance between two adjacent Antinodes? (4) The distance between two adjacent nodes or two adjacent antinodes is equal to half of the wavelength (Figure 5). (5) As the displacement of the nodes is always zero, the waveform is not travelling. Hence energy is confined between two adjacent nodes. What is the distance between […]
Why Nuclear is not good?
Why Nuclear is not good? Nuclear energy produces radioactive waste A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years. Is it bad to […]

What is the difference between inertial and non-inertial frame?
What is the difference between inertial and non-inertial frame? Distinguish between inertial and noninertial frames of reference….Solution. Inertial frame of reference Non-inertial frame of reference 3. The body does not accelerate. The body undergoes acceleration 4. In this frame, a force acting on a body is a real force. The acceleration of the frame gives […]
What are the limits to hair evidence?
What are the limits to hair evidence? A limitation of using hair as evidence from a crime scene is that hair can not be directly linked to a suspect. It is impossible to say that a hair sample came from only one specific person. What is the protocol for storing biological evidence? Neglect of proper […]
Why is volume directly proportional to temperature?
Why is volume directly proportional to temperature? If the amount of gas in a container is increased, the volume increases. Gay Lussac’s Law – states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more […]
What is the relationship between the volume and temperature of a gas?
What is the relationship between the volume and temperature of a gas? Charles’s law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant. with k being a proportionality constant that depends on the amount and pressure of the […]
