nucleosynthesis is the process in nuclear reaction
Friction because when it hits the floor or ice it damages it by making little micro cuts
<span>Let q1 = -10.0 nC , and q2 = 20.0 nC
E1(P) + E2(P) = 0
|E1| = |E2|
|q1|/r1^2 = q2/r2^2
r2/r1 = sqr(q2/|q1|) = sqr 2
r2 = r1 + d
Solving : r1 = d/(sqr2 -1) = 33.8 cm ; r2 = 47.8 cm
(a) V = (1/4pi €o)(q2/r2 + q1/r1) = 110 V
(b) V=0 |q1|/r1 = q2/r2
r2 = 2 r1 ; r2 + r1 = d
solving
r2 = 28/3 cm ; r1 = 14/3 cm
E = E1 + E2 = (1/4pi€o)(|q1|/r1^2 + q2/r2^2)
E is // at X axis and direct from q2 to q1.</span>
Answer:
1980 kg m/s due south
8.2 m/s2 north-west
Explanation:
In order a quantity to be a vector, it should both has a magnitude and direction.
27 J/s --> Only magnitude. (Power)
1980 kg m/s due south --> Both magnitude and direction. (Momentum)
8.2 m/s2 north-west --> Both magnitude and direction. (Acceleration)
3.2 mi straight up --> Direction is not clear. (Position)
2.9 m/s2 --> Only magnitude. (Magnitude of acceleration)
293 K --> Only magnitude. (Temperature)
200 s --> Only magnitude. (Time)
