Answer:
The temperature of the oven is: T2= 309.86 ºC.
Explanation:
α= 0.00446 1/ºC
R1= 14 Ω
R2= 31.1Ω
T1= 36ºC
R2= R1 * {1+α * (T2-T1) }
T2= {[(R2/R1)-1] * 1/α} + T1
T2= 309.86ºC
Answer: 0.3 m/sec
Explanation:
Vrel = (Vs-Vm) = (0.8-0.5) = 0.3 m/sec
(a) 764.4 N
The weight of the astronaut on Earth is given by:
where
m is the astronaut's mass
g is the acceleration due to gravity
Here we have
m = 78.0 kg
g = 9.8 m/s^2 at the Earth's surface
So the weight of the astronaut is
(b) 21.1 N
The spacecraft is located at a distance of
from the center of Earth.
The acceleration due to gravity at a generic distance r from the Earth's center is
where G is the gravitational constant and M is the Earth's mass.
We know that at a distance of r = R (at the Earth's surface) the value of g is 9.8 m/s^2, so we can write:
(1)
the acceleration due to gravity at r=6R instead will be
And substituting (1) into this formula,
So the weight of the astronaut at the spacecratf location is
Answer:
46 m at 9.5 degrees east of south
