The tune-up specifications of a car call for the spark plugs to be tightened to a torque of 50 N. m. You plan to tighten the plugs by pulling on the end of a 28-cm-long wrench. Because of the cramped space under the hood, you'll need to pull at an angle of 105 respect to the wrench shaft. with Part A With what force must you pull? Express your answer in newtons. F = 180 N >

Kindly answer correctly. Pleae show the necessary steps. Thanks

A railroad curve is laid out on a circle. What radius should be used if the track is to change direction by 20° in a distance of 100 miles? Round your answer to the nearest mile.

On the map, let the +x-axis point east and the +y-axis north. An airplane flies at 880 km/h northwestward direction (i.e., midway between north and west). Can you help me visualize the components of the first velocity, and when the plane flies due south at the same velocity?   I am afraid I can properly visualize or understand in simple terms what is asked.  My point can you help to understand the right angle theorem to the angle.

A jet plane travels towards a ground-based radar dish. Radar locates the jet plane at a distance D = 11 km from the dish, at an angle θ = 46° above horizontal. 1.) What is the jet plane’s horizontal distance, DH in meters, from the radar dish? 2.)What is the jet plane's vertical distance, DV in meters, above the radar dish? 3.)Write an expression for the distance vector, D, in rectangular form in terms of D and θ, in a coordinate system with the dish at the origin and the unit vectors i and j in the horizontal and vertical directions. (to the right and up)
