Answer:
A.
collect samples.
Explanation:
The main goal of science is to gain knowledge about the natural world, but this goal is nearly impossible to achieve without technology.
Technologies are products or processes that are created to solve a problem and/or take care of a human need. Technology is often used in science to collect samples, make measurements, collect and store data, analyze data through computations and graphing, and access remote locations, such as outer space.

Explanation:
Boyles law is the pressure of a fixed mass of gas which is inversely proportional to its volume provided that the temperature is kept constant.
Answer: part a) both the tension and gravity vectors will be pointing downwards.
part b) the tension vector will be pointing upwards and the gravity will be pointing downwards.
Explanation:
part a) Since you are looking at the FBD for the steel cable here, the tension will be pointing downwards because the girder is hung from the cable which creates a downwards tension. Gravity will always point downwards, to the ground.
part b) Since you are looking at the FBD for the girder here, the tension will be pulled upwards because the cable is weighted which creates an upwards tension. Gravity will always point downwards, to the ground.
Sorry for the poor explanation, but hopefully this makes sense.
Answer:
Gravity dams are so named because they are held to the ground by gravity – they weigh a lot, and are typically made from concrete or stone. Engineers must de-water the river where the dam is meant to be built. This is done by diverting the river through a tunnel that runs around the intended construction zone.
