tides
Q: Answer the following question given this paragraph: Water on Mars can't be a liquid. This is because the pressure of the atmosphere is too low. The planet does have a lot of water; it is in the form of ice. The south pole of Mars has a very visible ice cap. Scientists also have evidence that there is also a lot of ice just under the Martian surface. The ice melts when volcanoes erupt. At this times liquid water flows across the surface. Q: What form does water take on the planet mars? Choices: - plasma - gas - liquid - ice A:

Answer the following question given this paragraph: In the absence of a net force, objects move in a straight line. If they turn that is, if their velocity changes, even only in direction there must be an applied force. Forces which cause objects to turn around continuously in a circle are known as centripetal forces. When an object moves in a circle its velocity at any particular instant points in a direction tangent to the circle. The acceleration points towards the center of the circle, and so does the force acting on it. This is only natural, when you think about it if you feel a force pushing you towards your left as you walk forward, you will walk in a circle, always turning left. Q: Forces which cause objects to turn around continuously in a circle are known as? Choices: - frictional forces - tension forces - hydrodynamic forces - centripetal forces A:
**Answer**
centripetal forces
