What is the apparent path of the sun on the sky on March 21 as viewed from the equator? The Sun crosses the celestial equator moving northward at the vernal equinox around March 21 and crosses the celestial equator moving southward at the autumnal equinox around September 22. Which is longer the length of a […]
Is .34 alcohol level high?
Is the amplitude of a wave is doubled what will be the effect on its loudness?
Is the amplitude of a wave is doubled what will be the effect on its loudness? Loudness of sound is directly proportional to the square of the amplitude. When amplitude is doubled, loudness becomes 4 times. What happens to amplitude if intensity is halved? If the amplitude of a wave is , the power carried […]
Is Moon Photography astrophotography?
Is Moon Photography astrophotography? The best part about moon photography is the variety of creative compositions possible, whether it be a landscape photo or a high magnification close-up through a telescope. Photographing the moon often leads to other forms of photography including planetary and deep-sky astrophotography. Does the Moon ruin stargazing? No, you won’t be […]
Is energy lost in pure rolling?
Is energy lost in pure rolling? When an object is rolling without slipping, the point of contact with the surface always has zero velocity relative to the surface. (since the point of contact has no displacement caused by the static friction.) Since there are no non conservative forces now, energy can be conserved. What does […]
What are 2 similarities of unicellular and multicellular organisms?
What are 2 similarities of unicellular and multicellular organisms? Both unicellular and multicellular organisms share the characteristics of life: they grow, respond to stimuli, maintain homeostasis (an internal balance), reproduce, pass on genetic material to offspring, and obtain or use energy. What are the similarities and differences between unicellular and multicellular organisms? Difference Between Unicellular […]
Which clouds are highest in the sky?
Which clouds are highest in the sky? Noctilucent clouds are the highest clouds in the sky, however they are not associated with weather like the rest of the clouds in this table. What is Cloud Services example? Examples would include: Dropbox, a file storage and sharing system. Microsoft Azure, which offers backup and disaster recovery […]

What describes Seema’s error? Which describes Seema’s error? The y and x values are switched. What does it mean when an object […]
What are 5 examples of conduction?
What are 5 examples of conduction? Conduction: Touching a stove and being burned. Ice cooling down your hand. Boiling water by thrusting a red-hot piece of iron into it. Is stir frying vegetables conduction convection or radiation? Cards Term 1. Hot water rises and cold water sinks. Definition convection Term 2. Stir frying vegetables is […]
When source is moving and observer is stationary?
When source is moving and observer is stationary? Doppler effect- the shift in frequency of a wave where the source and observer are moving relative to one another. Two different cases for sound: Observer moving – source stationary Source moving- observer stationary. Relative velocity of wave (v-vo) decreases. So far, we have only considered stationary […]
