Suppose there are 5 properties of a material (color, size, temperature, etc.) and you want to test how something depends on one of those properties. To correctly perform an experiment, how many dependent variables can you have, how many independent, and how many variables must remain the same?

An astronaut floating in space is trying to use her jetpack to get back to her space station, but she is being pulled away by a nearby planet, as shown in the image below. her jetpack provides a constant thrust of 310 n. if she angles her jetpack in such a way that it cancels out the vertical force due to the planet's gravity, what is her net horizontal force? thaud 487 o a. 54.8 n toward the space station o b. 212.9 n toward the space station o c. 185.2 n toward the space station o d 956 n toward the space station
