Answer:A)3074m,3074.37m/s
B)12905.4m,19100.54m/s
Explanation:the formula for electric field =V/d
Where V=velocity of the particle,d=distance covered from the electric field source
A)E=V/d
1.48=4.55×10^5/d
d=4.55×10^5/1.48=3074m
Distance of B from centre of the field=3074+0.370=3074.370m
B)d=V/E=1.91×10^4/1.48
d=12905.4m
At point B
Distance=12905.4+0.370=12905.770
V=Ed=12905.770×1.48=19100.54m/s
True, it can be seen from Earth at times
Answer: (A) a back-and-forth motion on the surface of the earth
Explanation:
Earthquake generates seismic waves which are longitudinal waves.Longitudinal waves travel parallel in the direction of transfer of energy. Meaning that they travel in back and forth motion.
Longitudinal waves consist of compressions and rarefactions. When compressions occur when particles are close together and are regions of high pressure. Whereas, rarefactions occur when particles are further apart and regions of low pressure.
