Answer:
Velocity ratio of a lever is 3 means distance travelled by effort is 3 times the distance travelled by the load. Efficiency of the pulley is 60%means 40% of the energy is lost in the machine due to the friction
Answer:
Option A, B, C and D
Explanation:
First to all, we need to remember something. Mercury is the first planet to our solar system, therefore, it's the closest planet to the sun. Because of this, temperatures of that planet are way too high.
Mercury has a very thin atmosphere so it barely exists. It also has a low gravity and receives large gusts of solar winds from the Sun, that's why it has high temperature, and therefore, it's escape velocity is very low too.
Of course, it's one of the smallest planets in our solar system, so,the atmosphere of Mercury is unstable and constantly shifting. As the atmosphere’s materials are being made, they are also being taken away at the uppermost layers due to solar winds. The composition of the atmosphere can also change as you move across the planet.
Answer:
Based on the passage, the article's claim is not true. Therefore, the answer is:
No, because radio waves have energies that are too low to fall in the ionizing range.
Explanation:
Radio waves are generally known as forms of non-ionizing radiation. This means that they do not have enough energy, unlike microwaves, to separate electrons from atoms or molecules, thereby ionizing them. They cannot cause electron displacement, as claimed in the article. Therefore, they cannot break chemical bonds, which can cause chemical reactions or DNA damage. As non-ionizing radiation, radio waves occur at lower frequencies in the electromagnetic spectrum.
