Accomplished silver workers in india can pound silver into incredibly thin sheets, as thin as 3.00 10-7 m (about one-hundredth o
postnew [5]
The density of silver is ρ = 10500 kg/m³ approximately.

Given:
m = 1.70 kg, the mass of silver
t = 3.0 x 10⁻⁷ m, the thickness of the sheet

Let A be the area.
Then, by definition,
m = (t*A)*ρ

Therefore
A = m/(t*ρ)
    = (1.7 kg)/ [(3.0 x 10⁻⁷ m)*(10500 kg/m³)]
    = 539.7 m²

Answer: 539.7 m²

Annette [7]

Answer:

The resistance of the lamp is 4Ω.

Explanation:

You have to apply voltage formula :

V = I × R

R = V ÷ I

R = 240 ÷ 60

R = 4 Ω

A point on a string undergoes simple harmonic motion as a sinusoidal wave passes. When a sinusoidal wave with speed 24 m/s, wave
Anit [1.1K]

Answer:

5.03 m/s

Explanation:

Give

Speed = v = 24m/s

Wavelength = λ = 30cm = 0.3m

Amplitude = A = 1.0cm = 0.01m

The velocity of a point in Simple Harmonic Motion

at any time t is given by the following formula

v = ωA cos ωt

The value is the Maximum when cosωt.

The maximum value of cosωt. is 1.

Hence the maximum velocity is ωA

Velocity of the wave v=n λ

n = v/ λ = 24 /0.3 = 80

ω = 2πn = 2π*80 = 502.86 rad/s

Maximum velocity of the particle is

ωA = 502.86 * 0.01 = 5.03m/s
