a)

• P = F/A

P = pressure = 630 N/m^2

F = force

A = area

F = mg = 0.50 kg x 9.8 m/s^2 = 4.9 N

m= mass

g= gravity

P = F/A

A = F/P

A = 4.9 N / 630 N/m^2 = 7.778 x 10^-3 m^2

b)

• Area of a circle = pi* radius ^2

7.778 x 10^-3 m^2 = pi* radius ^2

√(7.778 x 10^-3 m^2 / pi ) = radius

radius = 0.04976 m

Answers:

a ) 7.778 x 10^-3 m^2

b) 0.04976 m

Capatul unei conducte metalice cu lungimea de 510 m
elixir [45]

 t = d/v = 510:340 = 1,5 secunde

1,4 secunde, deci

t2 = 1,5 - 1,4 = 0,1 secunde

v2 = distanta/timp = 510 metri / 0,1secunde  

= <span>5100 metri / secunda</span>

Elza [17]

Answer:

Net capacitance

=

let net capacitance be R

1/R = 1/10+1/10

1/R=2/10

1/R=1/5

cross mutiply

R=5

the net capacitance is 5ohms
