Answer:
Thickness of Styrofoam insulation is 0.02741 m.
Explanation:
Given that,
Height = 0.25 m
Depth = 0.5 m
Power = 400 W
Temperature = 33°C
We need to calculate the area of Styrofoam
Using formula of area
Put the value into the formula
Inner surface temperature of freezer
Outer surface temperature of freezer
We need to calculate the thickness of Styrofoam insulation
Using Fourier law,
Put the value into the formula
Hence, Thickness of Styrofoam insulation is 0.02741 m.
Answer:
Gravity
Explanation:
The Hubble is continually attracted to the earth due to the action of gravity. Therefore, it is thanks to gravity that the space telescope is kept in orbit. Without him, the direct motion generated by inertia would take him out of course. Gravity slows it down and keeps it in the curved path of its orbit around the Earth.
Answer:
Xcm = (6 * 0 + 4 & 3 + 2 * 0) / 12 = 1
Ycm = (6 * 0 + 4 * 0 + 2 * 3) / 12 = 1/2
(Xcm , Ycm) = (1 , 1/2)
Using definition of center of mass
Answer:
27km.
Explanation:
Jessie will run for a duration of time, which is the time it takes for Melissa and Rory to meet each other.
Together combined, Melissa and Rory runs at 14km/h. The bike trail is 21km, so it will take 1.5 hours.
Jessie runs at 18km/h, so Jessie will run 18 * 1.5 = 27km.
