Answer:
1,056
Explanation:
mean tensile strengths is the sum of all the tensile strengths given divided by the number of tensile strengths given
Given tensile strength are 1037,1047,1066,1048,1059,1066,1073,1070,1040
mean tensile strengths = (1037 + 1047 + 1066 + 1048 + 1059 + 1066 + 1073 + 1070 + 1040)/9
= 9506/9
= 1,056.22
≈ 1,056
Answer:
B. South
Explanation:
An electric field can be defined as the amount of electric force per unit charge. The direction of the electric field can be determined by the motion of a positive test charge under the electric force.
The direction of electric field is radially outward for a positive charge and radially inward for a negative charge. Thus, for the electric field points toward SOUTH at a position directly south of a positive charge.

Answer:
9.67 A
Explanation:
The weight of a student with a mass of m = 75 kg is:
where g=9.8 m/s^2 is the acceleration due to gravity.
We want the magnetic force on the wire to be equal to this weight. The magnetic force on the wire is
where
I is the current in the wire
L = 2.0 m is the length of the wire
B = 38 T is the magnetic field
is the angle between the direction of B and L
Since we want W=F, we can write
And we can solve it to find the current I:
