Answer:
Volume of secret cavity = 4 x 10⁻⁶m³
Explanation:
The weight of the sculpture in air is 15.76 N
Mass of the sculpture = 1.61 kg
Mass = Volume x Density
1.61 = V x 8470
Volume of brass =1.90 x 10⁻⁴ m³
When it is submerged in water, the weight is 13.86 N.
That is
Weight of sculpture - Weight of water displaced = 13.86 N
15.76 - Weight of water displaced = 13.86
Weight of water displaced = 1.9 N
Mass of water displaced = 0.194 kg
Mass = Volume x Density
0.194 = V x 1000
Volume of water displaced =1.94 x 10⁻⁴ m³
Volume of secret cavity = Volume of water displaced - Volume of brass material
Volume of secret cavity = 1.94 x 10⁻⁴-1.94 x 10⁻⁴ = 0.04x 10⁻⁴ = 4 x 10⁻⁶m³
The average amount of solar energy incident on the PV per day is 10000 kWh/day.
<h3>
Equation</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let the PV array has an area equal to 50 square meters. Hence:
Average amount of solar energy incident on the PV per day = 200 kWh/m²/day * 50 m² = 10000 kWh/day.

Density of rock = 3.23 Kg/m^3
Given:
mass of Moon rock = 8.94 kg
apparent mass of Moon rock = 6.18 kg
To Find:
density of the rock
Solution: It is a universal fact that mass of an object remains constant whether measured on earth or on moon.
Mass of rock on moon/earth = 8.94 kg
When the block is immersed in water then;
Loss in weight = weight of water displaced
Loss in weight = 8.94 - 6.18 = 2.76 kg
As we know that water has a density of 1g/cm^3 (1000kg/m^3)
Volume of water = volume of the rock = Mass/density = 2.76 kg
density of rock mass/volume = 8.94/2.76 = 3.23 Kg/m^3
Density of rock = 3.23 Kg/m^3

<span>The fact that light travels at 300,000 km/s is a consequence of Energy Conservation
The particle that move with that kind of speed creates energy way faster than the particle that don't. Which means that it would require less effort to produce the energy,</span>
