1) The astronaut's sense of imbalance in a space flight is due to the rotation of a device in which he or she feels a fictitious
gravity that mimics gravity. The the device rotates according to the mathematical equation: n =g^0.5/2πr^0.5 Where n is the rotational speed and is measured in rotations per second (s). (r) is the radius of the circulator and is measured in meters (m). (g) is a simulation of gravity. Calculate the rotation speed of a device, that has a radius of 1.7 meters and rotates to simulate the gravitational force which equals to: g = 9.8 m/s^2 with steps please
If 2x+y=5, then y=5-2x, so he substituted 5-2x correctly. x+4x=5x, so he combined like terms correctly. If 5x-10=10, then 5x=10+10 -> 5x=20, so he subtracted 10 from the right side instead of adding 10 to the right side.
