Flow rate calculations yield 220 cans, each with a volume of 0.355 l, leading to 78.1 l/min or 1.3 l/s or 0.0013 m³/s.
At Point 2:
A2 = 8 cm² = 0.0008 m²
V2 = Flow rate/A2 = 0.0013/0.0008 = 1.625 m/s
P1 = 152 kPa = 152000 Pa
At Point 1:
A1 = 2 cm² = 0.0002 m²
V1 = Flow rate/A1 = 0.0013/0.0002 = 6.5 m/s
P1 =?
Height = 1.35 m
Using Bernoulli’s principle;
P2 + 1/2 * V2² / density = P1 + 1/2 * V1² / density + density * gravitational acceleration * height
=> 152000 + 0.5 * (1.625)² * 1000 = P1 + 0.5 * (6.5)² * 1000 + (1000 * 9.81 * 1.35)
=> 153320.31 = P1 + 34368.5
=> P1 = 1533210.31 - 34368.5 = 118951.81 Pa = 118.95 kPa
Answer:
It eliminates recoil.
Explanation:
Every action has a corresponding reaction that is equal and opposite.
According to the conservation of momentum, when a single spore is released, the fern experiences a recoil that diminishes the energy and velocity of the spore. However, by ejecting the spores in pairs, the recoil is neutralized, allowing the entire energy to be imparted to the spores, which leads to increased launch speeds.
Answer: yes.
Explanation: The type of light striking the metal is visible light.
There are three factors involved:
1. The temperature
2. The specific heat of the metal
3. The thermal conductivity of the metal.
The increase in temperature of the metal is influenced by how light energy is absorbed and reflected; it will absorb some of the energy and won't reflect all of it.
When an object absorbs visible light, it transforms the short wavelength light into longer wavelength heat, leading to a temperature rise.
Answer:
Explanation:
To convert from gram / centimeter³ to kg / m³
gram / centimeter³
= 10⁻³ kg / centimeter³
= 10⁻³ / (10⁻²)³ kg / m³
= 10⁻³ / 10⁻⁶ kg / m³
= 10⁻³⁺⁶ kg / m³
= 10³ kg / m³
Thus, to convert the quantity in gm / cm³ into kg/m³, you need to multiply by 10³
2.33 gram / cm³
= 2.33 x 10³ kg / m³.
