Complete the following paragraph by Identifying the terms. Drag and drop your answer/s into the provided box. By the end of the sixteenth century, the observation of the astronomical bodies had progressed to a remarkable degree. Tycho Brahe built the large observatory on an island near Copenhagen. Tycho painstakingly recorded precise observations of the motions of the planets using and After Tycho's death, Johannes Kepler studied his data and devise the three laws of planetary motion. The first law states that each planet moves along a/an with the sun at one focus. The second law says that the from the sun to a planet sweeps out equal areas in On the other, the third law says that the of a planet's orbital motion is proportional to the cube of its from the sun. :: mechanical gadgetry :: unaided eye :: telescope : elliptical path :: radius vector :: equal intervals of time square of the period :: mean distance :: area

Q3.1 Please answer the following question throughly and detailed. Need to understand the concept.
Suppose we tie a ball to a string and whirl it around in a circular path whose radius is 40 cm. (0.40 M). Draw a free body diagram next to the physical picture below. Be sure to include the tension force and the gravitational force. Assume the string make an angle of 30° with the horizontal. If the ball has a speed v of 2.5 m/s, what is the numeric value of the acceleration? Where is the force coming from that is producing that acceleration? What is the numeric value of the centripetal force if the mass is 0.5kg? What is the numeric value of the vertical component of the tension force?
This is an F=ma questions. Remember that force and acceleration are vectors. (That's what the boldface font means.) 1) A 14kg object accelerates at (2,4) m/s2. Calculate the magnitude of the force on the object, in Newtons. 2) Calculate the mass if F = (200, 300) N and a = (0.9, 0.3) m/s2. Enter 0 if there exists no answer.
