A camcorder has a power rating of 11 watts. If the output voltage from its battery is 8 volts, what current does it use?
Reika [66]

The camcorder uses a current of 1.4 A.

<em>P = VI </em>

<em>I</em> = <em>P</em>/<em>V</em> = 11 W/8 V = 1.4 A

<em>Note</em>: The answer can have only <em>one significant figure</em> because that is all you gave for the voltage. However, I calculated the current to two significant figures.

Describe the location of the negative charges of the atom in j.j thompsons plum pudding model
iren2701 [21]

The location of the negative charges is evenly distributed throughout the entire atom.

J. J. Tomson concluded that atoms are divisible and that the corpuscles are their building blocks.

Atoms are made up of smaller particles.

J. J. Thomson discovered the electron ( the negative charges of the atom) in 1897.

His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge and evenly distributed throughout the entire atom.

With this model, he abandoned his earlier hypothesis that the atom was composed of immaterial vortices.

Later, Rutherford demonstrate that J.J Thompson's Plum Pudding model was not accurate.

The ph of lemon juice is approximately 2.40. at this ph, the hydronium ion concentration is closest to which concentration? 4.0
swat32
pH = -log[H₃O⁺(aq)]

here the pH is given as 2.40.

Hence,
  2.40               = -log[H₃O⁺(aq)]
log[H₃O⁺(aq)]  = -2.40
[H₃O⁺(aq)]       = 3.98 x 10⁻³ M
                        = 4.0 x 10⁻³ M

Hence, the hydronium ion concentration in juice is 4.0 x 10⁻³ M.

Since, the pH is less than 7, the juice is acidic.
