2.The brightness of light, emitted by a bulb, is observed to decrease when anelectric heater is connected in series with it. Suggest the likely reason for thisobservation. |
|
Answer» Answer: The current remains the same in series but the potential difference changes at each point of the CIRCUIT in a series Explanation: As there are two objects (resistors) connected in series, having DIFFERENT RESISTANCE and different potential difference, the current USED by them remains constant in the circuit. The LIGHT becomes more dim due to the same current but different resistance. If it were the case that they were to be connected in a parallel circuit they would have worked efficiently. |

Some plants in grasslands have stong stems why |
|
Answer» Answer: This is a correct statement buddy! Explanation: SMALL animals can climb underground into their burrows to stay safe, but grasses and other plants common to grasslands can't run away. Instead, they are specially adapted to survive fire. Just as a small animal can be safe in an underground burrow, the parts of the plant that are underground are less likely to burn.Grassland plants have evolved so that as long as their roots survive, they can grow back after a fire very quickly. Trees and other plants not adapted to fire cannot grow back quickly, if they even survive. As a result, fire helps keep the grasslands from being overgrown by BUSHES and trees and turning into a forest.Grasslands are FULL of herds of hungry herbivores. These herbivores are hard on plants, but they can be a powerful force in making an area a grassland and keeping trees from taking it over. You see, grasses and other grassland plants have special adaptations to allow them to survive heavy grazing. Unlike many plants, grass can survive being grazed all the way to the GROUND. |
