How does a dimming mirror work? Technology. In auto dimming mirror technology, a forward-looking sensor detects low ambient light from headlights behind the car and directs the rear-view sensor to look for glare. The mirrors darken automatically in proportion to how bright the glare is, then clear once the glare is no longer detected. Why […]
Why onion has no chloroplast?
Why onion has no chloroplast? The clear epidermal cells exist in a single layer and do not contain chloroplasts, because the onion fruiting body (bulb) is used for storing energy, not photosynthesis. The vacuole is prominent and present at the center of the cell, surrounded by cytoplasm. Do plant cells have chloroplasts and mitochondria? Plant […]

Which compound becomes less soluble in water as the temperature of the solution is increased a HCl B KCl C NaCl D nh4cl? Thus, out of the given options HCl is a covalent compound, therefore, HCl is the compound that becomes less soluble in water as the temperature of the solution is increased. Why does […]
What are examples of lava plateau?
What are examples of lava plateau? The magma that comes out through narrow cracks or fissures in the crust spread over large area and solidifies. These layers of lava sheets form lava or volcanic plateaus. The Antrim plateau in Northern Ireland, The Deccan Plateau in India and the Columbia Plateau in the United States are […]
Which of the following is a white crystalline solid?
Which of the following is a white crystalline solid? Magnesium Oxide is an ionic compound, formed by the transfer of electrons from one element to the other. Since it is an ionic compound, MgO is solid. It is also white and crystalline in nature. What is meant by a crystalline solid? Crystalline solids consist of […]
What factor does not affect the total stopping distance of a vehicle?
What factor does not affect the total stopping distance of a vehicle? Visibility is one of a number of factors that do not affect your braking distance per se but can inhibit your thinking distance. The longer it takes for you to spot hazards in the road, the more time will have passed before you […]

What is the value of horizontal acceleration?
What is the value of horizontal acceleration? The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of […]
What is tan90 value?
Can the sign of the acceleration ever be positive for an object that is slowing down?
Can the sign of the acceleration ever be positive for an object that is slowing down? According to our general principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object also has a positive acceleration. Is it true that acceleration only takes place when speeding […]
