A track star in the long jump goes into the jump at 12 m/s and launches herself at 20.0° above the horizontal. What is the magnitude of her horizontal displacement? (Assume no air resistance.)

Answer The magnitude of the horizontal displacement of a track star in the long jump who goes into the jump at 12 m/s and launches herself at 20.0° above the horizontal can be calculated using the equations of motion. The

Find the resultant of these two vectors: 200. m due east and 400. m 30.0° north of west.

Answer: Resultant of Two Vectors The resultant of two vectors, such as 200 m due east and 400 m 30.0° north of west, is found by taking the sum of the components of each vector in a single vector. This

Are there any freIn the given system, process stream is heated to a specific temperature and after heating it is sent to another process. Process stream is fed to the system at 20°C and with 20 m3/h flow rate. Volume of the tank is 100 m3. Density of fluid is 1000 kg/m3, heat capacity is 0.8 kcal/kg, flow rate of saturated steam is 1000 kg/h and saturated steam enthalpy is 640 kcal/kg. It is known that the heat capacity and density are constant during the heating process. What is the fluid temperature exit of the tank when the process is at steady state? (F=F0)e AI-powered apps for solving science homework?

boat moves at 10.0 m/s relative to the water. If the boat is in a river where the current is 2.00 m/s, how fast is the boat moving relative to the ground as it travels straight across the river?

Answer: The Boat’s Speed Relative to the Ground The speed of the boat relative to the ground can be determined by taking into account the speed of the boat relative to the water and the speed of the current in

What is an hysteresis?

What is an Hysteresis? An hysteresis is a phenomenon in which a system’s response to a change in its environment is delayed, lagging behind the current conditions. It is commonly observed in physical systems, such as a mechanical system or
