At an air show a jet flies directly away from the stands at a speed of 1,204 km/h, emitting a frequency of 3,942 Hz, on a day when the speed of sound is 342 m/s. What frequency in Hz is received by the observers

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

c) up is the direction the magnetic force is acting on the charge.

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.
