Answer:
2. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.
Explanation:
The options are:
1. Before a volcano erupts, earthquake activity beneath the volcano decreases.2. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.3. When a volcano erupts, the amount of carbon dioxide and sulfur dioxide emitted decreases. 4.Scientists measure the amount of these gases to determine the amount of magma present in the volcanic reservoir.
The answer is certainly 2. as seismometers are being used to find out the details of the earthquake activities which occur inside a volcano. And with this information, the volcanologists then predict the eruption of that particular volcano. Hence, the 2nd option does not have any factual errors, and all the others have factual errors.
Answer:
WHITE HACKERS
Explanation: When a white hat hacker discovers a vulnerability, they will exploit it only with permission and not tell others about it until it has been fixed. In contrast, the black hat will illegally exploit it or tell others how to do so. The gray hat will neither illegally exploit it nor tell others how to do so.
Answer:
c)both a and b
Explanation:
If the tires are under inflated the the rolling resistance increases due to more surface are of tire now touches the ground hence there is more friction.Since the rolling resistance increases the tire will face difficulty in turning hence the steering the tires will become more hard.Since rolling resistance is increased so the engine has to work more to run the car hence it will consume more fuel.
