Will a heavier ball roll farther than a lighter ball? The heavy one would only roll farther if they had the same acceleration. OP said that the two balls are pushed with the same energy (I assume he means force). If you use to same amount of energy to push both balls, the lighter ball […]
Where can I get negative ions?
Where can I get negative ions? Negative ions exist in nature in tons of places, including: ultraviolet (UV) rays from the sun. discharges of electricity in the air after a thunderclap or lightning strike. wherever water collides with itself like a waterfall or the ocean shore (creating the Lenard effect) How can I get negative […]
What is the force between two small charged spheres?
What is the force between two small charged spheres? Hence, force between the two small charged spheres is 6×10−3 N. The charges are of same nature. Hence, force between them will be repulsive. What is the force on the second sphere due to the first? Step by step solution by experts to help you in […]
Which is the perpetual source of energy?
Which is the perpetual source of energy? Perpetual energy may refer to: Perpetual motion, the property of an imaginary device that, once started, continues to move forever with no input of external energy. Renewable energy, energy collected from resources that are naturally replenished on a human timescale. Is gravity perpetual motion? It is true that […]
How much does it cost to fix hydrostatic pressure?
How much does it cost to fix hydrostatic pressure? Fixing this is between $350 and $500 per crack. Hydrostatic pressure is a different story. This is pressure that builds up underground when the water has nowhere to go. It forces itself up and through your foundation, often causing cracks. How do you know if you […]
Why commutator is needed?
Why commutator is needed? All generators produce a sine wave, or AC currents when the rotor turns in the magnetic field. The commutator on the DC generator converts the AC into pulsating DC. The commutator assures that the current from the generator always flows in one direction. What is a commutator in math? In mathematics, […]
What is the electron carrier for photosynthesis called?
What is the electron carrier for photosynthesis called? NADPH What substances are recycled between photosynthesis and cellular respiration? The four substances recycled during photosynthesis and respiration are: carbon dioxide (CO2), which is emitted as waste in cellular respiration and used by plants to make glucose, oxygen (O2), which is emitted as waste by plants and […]
How did the civil rights movement achieve some of its goals of equality?
How did the civil rights movement achieve some of its goals of equality? Civil Rights Act of 1964 King and other civil rights activists witnessed the signing. The law guaranteed equal employment for all, limited the use of voter literacy tests and allowed federal authorities to ensure public facilities were integrated. What strategies were used […]
What is a genotype vs phenotype?
What is a genotype vs phenotype? A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics. For example, having blue eyes (an autosomal recessive trait) is a phenotype; lacking the gene for brown eyes is a genotype. What gametes can be produced by AaBb? There are four possible […]
What are the impacts of fire hazards?
What are the impacts of fire hazards? The side effects of a fire also represent a hazard. Firstly the fire will deplete oxygen from the surrounding atmosphere. Most casualties from a fire die from the smoke and lack of oxygen. Secondly, especially where plastics are being burnt, the fumes could be toxic, and anyone exposed […]
