Two forces act at a point in the plane. The angle between the two forces is given. Find the magnitude of the resultant force. forces of 198 and 180 lb , forming an angle of The magnitude of the resultant force is . (Round to the nearest pound as needed.) 16 Two forces act at a point in the plane. The angle between the two forces is given. Find the magnitude of the resultant force. forces of 288 and 307 newtons, forming an angle of The magnitude of the resultant force is newtons. (Round to the nearest newton as needed.) Cuando un eje de longitud L y sección transversal uniforme con radio c es sometido a un par de torsión T y se considera deformación en el rango elástico, se puede afirmar que: Seleccione una: El ángulo de giro experịnentado por el eje es proporcional al módulo de rigidez del material de construcción del eje El ángulo de giro experimentado por el eje es inversamente proporcional al par de torsión T aplicado al eje. La cantidad de giro del eje varía de acuerdo al momento polar de inercia del área seccional en el eje. El ángulo de giro experimentado por el eje es proporcional al par de torsión T aplicado al eje.

Find the magnitude of the resultant force. forces of 288 and 307 newtons, forming an angle of The magnitude of the resultant force is newtons. (Round to the nearest newton as needed.) Do convex mirrors make things look closer than they really are?1) True2) False A toy rocket is launched from the top of a building 139 feet tall at an initial velocity of 166 feet per second. a) Give the function that describes the height of the rocket in terms of time . b) Determine the time at which the rocket reaches its maximum height, and the maximum height in feet. c) For what time interval will the rocket be more than 484 feet above ground level? d) After how many seconds will it hit the ground? a) The function that describes the height of the rocket in terms of is 12) Comic-strip Superhero meets an asteroid in outer space and hurls it at , as fast as a speeding bullet. The asteroid is a thousand times more massive than Superhero. In the strip, Superhero is seen at rest after the throw. Taking physics into account, what would be the recoil speed? 11) A 5 -kg fish swimming swallows an absentminded fish swimming toward it at a speed that brings both fish to a halt immediately after lunch. What was the speed of the approaching smaller fish before lunch? Why? 10) If mefore vafter, and a 2 -kg blob of play dough moving at slams into a 2 - kg blob of play dough at rest, what is the speed of the two stuck together blobs immediately after colliding? 9) How would the combined momentum of the two cars before collision compare to the momentum of the entangled cars after collision on a perfectly slippery road?
