Physics
1 answer:
makvit [3.9K]4 years ago
3 0

Answer:

Horizontal component of pull = (cos 55 x 33.9) = 19.4N.

Net horizontal force = (19.4 - 14.2) = 5.2N.

Work = (fd) = (5.2 x 13.5) = 70.2 Joules.

Rounded to 1 decimal place throughout.

An initially uncharged 3.53 × 10 − 6 F capacitor and a 7290 Ω resistor are connected in series to a 1.50 V battery that has negl
GarryVolchara [31]

Answer:

The initial current, Io = 2.06×10^-4A

Explanation:

The I itial current ,Io of a circuit is given by:

Io = Vo/R

Where Vo = initial votage

R = resistance in ohms

Given:

Vo = 1.50V

R = 7290ohms

Io = 1.50/ 7290

Io = 2.06 ×10^-4A
