ANS:D - Watermelon

Explanation: All except Watermelon grow on trees, while watermelon grows on creepers.

ANS:B - is lowered as the load increases

The battery is already charged now when the load is connected it is in discharging mode. So when load increases (here load increases means a device that we connected is drawing more current from source) voltage will come down gradually. So it is not like R increases I decreases so V decreases. One important thing is load resistance increases means are increasing. But load increasing means the current that is drawing by the device is increasing.

ANS:D - neither silting nor scouring occurs at bottom.

With self-cleansing velocity in sewers, scouring occurs at the bottom. Self-cleansing velocity refers to the minimum velocity required in a sewer to prevent sediment deposition and maintain a self-cleaning state. When the flow velocity in the sewer reaches or exceeds the self-cleansing velocity, it has enough energy to keep sediments suspended and prevent them from settling at the bottom of the sewer. Instead, the flow is capable of dislodging and carrying away any sediment that may have accumulated, leading to scouring of the bottom surface. Therefore, the correct statement is: scouring occurs at bottom.

ANS:B - 16
