1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23 25, 27,29 if we add 3 numbers From this we get the answer 30
Westkost [7]
Answer:
none of these numbers added equal 30
Explanation:
it is impossible to get 30 when you have three odd numbers
Explanation:
It is given that,
Length of wire, l = 0.53 m
Current, I = 0.2 A
(1.) Approximate formula:
We need to find the magnitude of the magnetic field made by the current at a location 2.0 cm from the wire, r = 2 cm = 0.02 m
The formula for magnetic field at some distance from the wire is given by :
B = 0.000002 T
(2) Exact formula:
B = 0.00000199 T
or
B = 0.000002 T
Hence, this is the required solution.
Your grade will probably go down to a D 68% or little higher than that

Answer:
6.54 x 10^-10 N/kg
Explanation:
mass of the shell, M = 135 kg
radius of shell, R = 1.49 m
distance from the centre of the shell, r = 3.71 m
The gravitational filed is given by
E = 6.54 x 10^-10 N/kg
Thus, the gravitational field intensity at a distance 3.71 m is 6.54 x 10^-10 N/kg.
