Answer:
The jewelry is 2896.54_Kg/m^3 less dense than pure silver
Explanation:
Density of jewellery = (mass of jewellery) ÷ (volume of jewellery)
=3.25g ÷ 0.428mL = 0.00325Kg÷0.000000428m^3 = 7583.46Kg/m^3
The density of silver is 10490_Kg/m^3 which is (10490 - 7583.46) 2896.54_Kg/m^3 more dense than the jewellery
The density of Silver [Ag]
The weight of Silver per cubic centimeter is 10.49 grams or the weight of silver per cubic meter is 10490 kilograms, that is the density of silver is 10490 kg/m³; at 20°C (68°F or 293.15K) at a pressure of one atmospheres.
Answer:
f = 8 Hz
Explanation:
Given data:
Wavelength of wave = 0.5 m
Speed of wave = 4 m/s
Frequency = ?
Solution:
Formula:
f = v/λ
f = frequency
v = speed
λ = wavelength
Now we will put the values in formula.
f = v/λ
f = 4 m/s / 0.5 m
f = 8 s⁻¹
s⁻¹ = Hz
f = 8 Hz
