Answer:60 ohms
Explanation:
This is a series connection
Total resistance=30+15+15
Total resistance=60
Total resistance=60 ohms
The lists that arranges the Earth's compositional layers in order of increasing density is CRUST, MANTLE AND THEN CORE. The core is considered as the most dense and the lithosphere, which makes the outermost core, is considered as having the least density. Hope that this answer helps.
Answer:
W = 1014 J = 1.014 KJ
Explanation:
As, Sam has to stop the boats in the log ride. Therefore, the work Sam needs to do, in order to stop a boat must be equal to the kinetic energy of the boat:
Work Done by Sam = Kinetic Energy of the Boat
W = K.E
W = (1/2)mv²
where,
m = mass of boat and its rider = 1200 kg
v = speed of the boat = 1.3 m/s
Therefore,
W = (1/2)(1200 kg)(1.3 m/s)²
<u>W = 1014 J = 1.014 KJ</u>
