Explanation:
When the speed of sound near the ground is reduced, (such as on a cold day when the layer of air nearest ground is colder than the air above) the higher speed of the wavefronts above cause a bending of sound toward the ground.
I believe that the answer to the question provided above is that with increase in resistance provided with constant current, Power dissipated will be lessen since power loss is high. Low power dissipation has low heat production. Hope this helps!! Have a great day!! :)
Momentum refers the amount of motion that a moving object contains. It is calculated from the product of the mass and the velocity of an object. It has SI units of kg-m/s. We calculate as follows:
momentum = mass x velocity
momentum = 0.45 kg x 25 m/s
momentum = 11.25 kg-m/s
Answer:
A gamma ray, light from a lamp, and a microwave are examples of electromagnetic radiation.
Explanation:
Gamma radiation, visible light (light from a lamp), and microwaves are all apart of the electromagnetic spectrum.
