Answer:
The ring of fire is caused by the subduction of pacific plates under the continental plates. In geology subduction is a process that happens as the one of tectonic plates move under the other and the gravity force it to sink into the mantle.
Explanation:
The gravitational acceleration is measured at 3.16 m/s² by the pendulum method.
We need to know about the pendulum to solve this problem. The periods of the pendulum depend on the length of the string and gravitational acceleration. It can be determined as
T = 2π√( l / g )
where T is periods, l is the length of string, and g is gravitational acceleration.
From the question above, we know that:
l = 2 m
T = 5 s
By substituting the following parameters, we get
T = 2π√( l / g )
5 = 2π√( 2 / g )
(5/2π)² = ( 2 / g )
g = 3.16 m/s²
Hence, the gravitational is measured at 3.16 m/s² by the pendulum method.

Venus is the second planet from the sun. It is usually the brightest object in our sky, other than our sun and moon. At sunrise and sunset, it looks like a big, bright star. It is bright because Venus has a cloud cover that reflects the sunlight. These clouds are made up of gases.
The given statement "An AED should only be used if a person is too tired to continue with chest compressions" is false.
Answer: Option B
<u>Explanation:</u>
Most people think that they are very tired after applying the compress for 2-3 minutes. When the compressor is tired, it tends to compress more slowly. For this reason, rescuers are advised to do compressions in every 2 min to prevent fatigue and optimise the compressions quality. This should only be done if the person does not show signs of life or is dead, does not respond and breathes normally.
For example, consider you come across the victim in a narrow place and you have two helpers: Rescuer 2 arrives with the AED (automated external defibrillator) and puts it on the opposite side from Rescuer 1, who does chest compressions. Rescuer 2 turns on the AED and fixes the electrodes to the victim's chest, connecting wires to the AED if necessary. Rescuer 1 can continue CPR (Cardiopulmonary resuscitation) by placing electrodes until the victim's heart rate has been analysed.
