Answer:
<h2>
650W/m²</h2>
Explanation:
Intensity of the sunlight is expressed as I = Power/cross sectional area. It is measured in W/m²
Given parameters
Power rating = 6.50Watts
Cross sectional area = 100cm²
Before we calculate the intensity, we need to convert the area to m² first.
100cm² = 10cm * 10cm
SInce 100cm = 1m
10cm = (10/100)m
10cm = 0.1m
100cm² = 0.1m * 0.1m = 0.01m²
Area (in m²) = 0.01m²
Required
Intensity of the sunlight I
I = P/A
I = 6.5/0.01
I = 650W/m²
Hence, the intensity of the sunlight in W/m² is 650W/m²
When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
Explanation:
a) The angular speed omega is given defined as
omega = #rev/period = 1 rev/(0.6 s) = 1.7 rev/s
= (1.7 rev/s)×(2pi/rev) = 10.5 rad/s
b) v = (omega)×r
= (10.5 rad/s)(0.110 m)
= 1.16 m/s
Answer:
18.4 m/s
Explanation:
The gravitational force between the Death Star and the Millenium Falcon is equal to the centripetal force that keeps the Millenium Falcon in circular orbit:
where
is the gravitational constant
is the mass of the planet
is the mass of the Millennium Falcon
is the orbital velocity of the Millennium Falcon
is the radius of the Death Star
is the altitude of the Millennium Falcon above the planet's surface
Solving the equation for v, we find the orbital velocity:
The range is: [26.86-0.02, 26.86+0.02] = [26.84, 26.88]
