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
Explanation:
36-4/4= 9 m/squared. meter per squared.
acceleration unit is meter per second Square.equation is velocity by time.for average final(36) minus initial(4)
Answer:
Explanation:
The force of the lake bottom on the boat = force the boat exerts on the bottom
force the boat exerts on the bottom = weight of the boat - buoyant force on the boat
so
The force of the lake bottom on the boat = weight of the boat - buoyant force on the boat
So
The force of the lake bottom on the boat will be less than its weight .
