The answer is is 730.5 days rounded, so A. 730
The frequency is exactly the rate at which the bug beats its wings.
If that "600" that you mentioned is 600 beats per second, then
THAT's the frequency . . . 600 per second. (600 Hz)
Answer:
1299 N/m²
Explanation:
Applying,
P = ρgh............... Equation 1
Where P = pressure of water at the bottom of the container, ρ = density of water, h = height of water in the container, g = acceleration due to gravity.
but,
V = πr²h............ Equation 2
Where V = volume of water, r = radius of the container
make h the subject of the equation
h = V/πr².................. Equation 3
From the question,
Given: V = 200 liters, = 200000 cm³, r = 70 cm
Constant: π = 22/7
Substitute these values into equation 3
h = 200000/[(22/7)(70²)]
h = 12.99 cm
h = 0.1299 m
Also given
Constant: g = 10 m/s², ρ = 1000 kg/m³
Substitute these values into equation 1
P = 0.1299(10)(1000)
p = 1299 N/m²
Answer:
Explanation:
Given data:
Thickness of aluminium sheet 10 cm
initial temperature = 25 degree celcius
Assumption
Thermal properties remain constant, transfer of heat by radiation is negligible.
from the information given in the question we have
T_S ≈T_∞ , it implies we have h → ∞
from table 4.2 Biot number → ∞ the value of
The fourier number is
Temperature at center after 15 second of heating
The clothing seems white because the entire light is reflected.
<h2>what is absorption and reflection?</h2><h3>Absorption:</h3>
This occurs when light is transformed into another type of energy. This happens when light vanishes while travelling through another medium.
<h3>reflection:</h3>
It is referred to as light reflection when a light ray hits a polished, smooth surface and bounces back. The incident light rays hit the surface and are reflected off of it. The beam that returns is referred to as the reflected ray.
