A circular area with a radius of 6.50 cm lies in the xy-plane.1.What is the magnitude of the magnetic flux through this circle due to a uniform magnetic field with a magnitude of 0.270 T in the + z -direction? ( φB =? Wb)2.What is the magnitude of the magnetic flux through this circle due to the same magnetic field (with a magnitude of 0.270 T), now at an angle of 52.1^\circ from the + z -direction? ( φB =? Wb)3. What is the magnitude of the magnetic flux through this circle due to the same magnetic field (with a magntiude of 0.270 T), now in the + y -direction? ( φB =? Wb)

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

Which of the following is not a means to accelerating? question 4 options: a)increase speed b)remain still c)decrease speed d)change direction

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer
