Explanation:
Answer:9.8x10^(-3) w/m°C
Explanation:
Quantity of heat(Q)=14.1w
Distance(d)=2.44cm=2.44/100=0.0244m
Area(a)=1.88m^2
Temperature change(t)=18.6°C
thermal conductivity(k)=?
K=(Qxd) ➗ (a x t)
K=(14.1x0.0244) ➗ (1.88x18.6)
K=0.34404 ➗ 34.968
K=9.8x10^(-3) w/m°C
Answer:
1.41 m/s, 7.85 rad/s
Explanation:
We can start by calculating the tangential velocity, which is given by:

where
r = 18 cm = 0.18 m is the radius of the circumference
T = 0.8 s is the period
Substituting,

Now we can also calculate the angular velocity, which is given by:

where again,
T = 0.8 s is the period
Substituting,

I would say the decision not to have children or to have only one child is becoming more common.
