Answer:
Explanation:
the sphere is solid and conducting, so the charge is uniformly distributed over its volume.
1.98 kilograms
weight on the moon = (weight on Earth / acceleration of Earth's gravity) x acceleration of the moon's gravity
weight on the moon = (12 kg. / 9.81 m/s^2) x 1.63 m/s^2
weight on the moon = 1.98 kg.

Angles will probably be 96° 35° and 49°
I tried to explain it with the working out, just re arrange the cosine rule for angles instead of side lengths.
if you need it explaining at all just message me :)
hoped it helped
This question is incomplete, the complete question is;
Scientists studying an anomalous magnetic field find that it is inducing a circular electric field in a plane perpendicular to the magnetic field. The electric field strength 1.5 m from the center of the circle is 7 mV/m.
At what rate is the magnetic field changing?
Answer:
the magnetic field changing at the rate of 9.33 m T/s
Explanation:
Given the data in the question;
Electric field E = 7 mV/m
radius r = 1.5 m
Now, from Faraday law of induction;
∫E.dl = d∅/dt
E∫dl = A( dB/dt )
E( 2πr ) = πr² ( dB/dt )
( 0.007 ) = (r/2) ( dB/dt )
( 0.007 ) = 0.75 ( dB/dt )
dB/dt = 0.007 / 0.75
dB/dt = 0.00933 T/s
dB/dt = ( 0.00933 × 1000) m T/s
dB/dt = 9.33 m T/s
Therefore, the magnetic field changing at the rate of 9.33 m T/s
Explanation:
T1 = 201k
T2 = 537k
C1 = 1220 m / s
C1/C2 =√(T1/T2)
C2 = C1×√(T2/T2)
C2 = 1220×√(537/201)
C2 = 1220 × √(179/67)
C2 = (1220√179)/(√69)
C2 = (1220√11993)/67 ≈ 1994.10924
