When a body is moving in circular path at a distance r from its center its velocity at any instant will be directed tangentially. This is what we call tangential velocity. It is calculated as follows:
Vt = r(ω)
where ω = 5 rev/s (2π rad / rev) = 31.42 rad / s
<span>Vt = 0.24(31.42) = 7.5 m/s</span>
The answer is 403 ml coz when you divide 0.403 with 1000 ml you get 403 ml
Answer:
Land heats faster
Explanation:
Land heats faster because absorbs much more solar radiation.
Answer:
a) Resistivity=R.A/L
Here, R=500000ohm, L=1.6m, A=2pi* (0.14/2)*0.002 m2=0.00088.........we have converted quantities into SI units
Resistivity=R.A/L
=500000*0.00088/1.6 = 440/1.6= 275 ohm.meter
b) pskin/pinterior =275/4.8=57.3
For second part, correct option is (A), because cross section area is smaller.
