Answer:

1.2kV

Explanation:

We are given that

Linear charge density,\lambda=358nC/m=358\times 10^{-9} C/m

1 nC=10^{-9} C

r_1=5 m

r_2=6 m

We have to find the potential difference between poinst 5.0 m and 6.0 m from the wire.

We know that potential difference of wire

V=2k\lambda ln\frac{r_2}{r_1}

Where

k=9\times 10^9

Substitute the values

V=2\times 9\times 10^9\times 358\times 10^{-9}ln\frac{6}{5}

V=1174.8 V

V=1.17 kV\approx 1.2 kV

1kV=1000 V

If V is a velocity, l a length, and v a fluid property having dimensions of L2T-1, which of the following combinations are quali
olasank [31]

Answer:

(b) Vl/v

Explanation:

The dimension for V is LT-1

The dimension for Length is L

The dimension for time is T

The fluid property v has a dimension of L2T-1, which is equal to square of the length divided by time.

for (a) Vlv

LT-1×L× L2T-1

= L^4T^-2

(b) Vl/v

LT^-1 ×L/ L^2 T^-1

=1. ; this is dimensionless.

(c)V2v

(LT^-1)^2 × L^2 T^-1

= L^4 T^-3

(d) V/(lv)

LT^-1/(LL^2 T^-1)

= L^-2

Does ammonification increase or decrease biomass? How?
Stels [109]

Hello! I'm not too knowledgeable on this topic, but I do know that ammonification is caused through different inorganic reactions. Or to metabolism systems of organisms. I also found it is a process in which nitrate reduction to nitrite is followed by the six-electron reduction of nitrite to ammonium.

dsp73

Answer:

Esses movimentos são movimentos naturais.

Explicação:

Se uma pedra cair do topo de um telhado ou edifício, a pedra se moverá em direção à terra, enquanto a fumaça produzida devido à queima da madeira vai para cima, então de acordo com Aristosteles esses tipos de movimento são chamados de movimento natural porque de acordo à definição de movimento natural que não requer nenhuma força, então esses dois movimentos também se movem na direção para baixo e para cima sem usar qualquer força, então podemos dizer que esses movimentos são naturais.
