One long wire lies along an x axis and carries a current of 31 A in the positive x direction. A second long wire is perpendicular to the xy plane, passes through the point (0, 4.3 m, 0), and carries a current of 67 A in the positive z direction. What is the magnitude of the resulting magnetic field at the point (0, 2.0 m, 0)? Number i Units µT

Pls consider the given significant digit

The tolerance is ± 1 in the 3rd significant digit.

Hi!! Can you help me what goes in each boxes? Thanks!!

derive the second equation from the first

In Figure (a), string 1 has a linear density of 2.08 g/m, and string 2 has a linear density of 4.84 g/m. They are under tension due to the hanging block of mass M = 677 g. Calculate the wave speed on (a) string 1 and (b) string 2. (Hint: When a string loops halfway around a pulley, it pulls on the pulley with a net force that is twice the tension in the string.) Next the block is divided into two blocks (with M, + M2 = M) and the apparatus is rearranged as shown in Figure (b). Find (c) M1 and (d) M2 such that the wave speeds in the two strings are equal. - String 1 String 2 Knot M (а) - String 1 String 2 M1 M2 (b)

The mass of an object was measured eight times on a balance readable to +1 g, and the followng values were recorded: (298 + 1)g. (311 + 1)g. (302 + 1)g, (312 + 1)g, (313 + 1)g, (317 + 1)g, (302 + 1)g, and (331 + 1)g. Find the final measurement ± m Select one: O a (310.75 + 4) g O b. (311 ±3.71) g O C. (311 +4) g O d. (310.75 +3.712) g
