Answer: The atomic mass of the platinum will be 195.

Explanation:

We know that,

Atomic mass is the sum of the electrons and protons.

Platinum is the chemical element and it is the symbol is Pt. The atomic number of the platinum is 78 and the atomic mass is the 195,084 u.

According to the question,

Rounded to the nearest whole number

Hence, The atomic mass of the platinum will be 195.

Provide at least one example of acceleration and explain why it would be considered a scalar or vector quantity.

Gelneren [198K]

Take gravity you are accelerated toward the ground. Since gravity has both a direction and a magnitude, then it is a vector.

An uncharged 30.0-µF capacitor is connected in series with a 25.0-Ω resistor, a DC battery, and an open switch. The battery has

kolezko [41]

Answer:

(a) Maximum current through resistor is 1.43 A

(b) Maximum charge capacitor receives is $1.50\times 10^{-3}\text{ C}$ .

Explanation:

(a)

In an RC (resistor-capacitor) DC circuit, when charging, the current at any time, t, is given by

$I(t) = I_0e^{-t/\tau}$

Here, $I_0$ is the maximum current and τ represents time constant which is given by RC (the product of the resistance and capacitance).

The maximum current is given by

$I = \dfrac{V}{R_\text{eff}}$

V is the emf of the battery and $R_\text{eff}$ is the effective resistance.

In this question, $R_\text{eff}$ = 10.0 Ω + 25.0 Ω = 35.0 Ω

$I = \dfrac{50.0\text{ V}}{35.0\ \Omega} = 1.43\text{ A}$

(b) The maximum charge is given

Q = CV

where C is the capacitance of the capacitor

$Q = (30.0\times10^{-6}\text{ F})(50.0\text{ V}) = 1.50\times 10^{-3}\text{ C}$

What phenomenon causes the fuzzy image? What kind of lens is used to correct this, and how is it corrected?

Amiraneli [1.4K]

Sample Response: This phenomenon is called chromatic aberration. This happens when light of different wavelengths focuses at different points. A converging lens is used to help light of different wavelengths focuses at a common point.
