A chandelier has sockets for 12 light bulbs. Suppose there are 75 of these

Physics

-- First, we need to know how many total sockets there are in the auditorium.

(75 chandeliers) x (12 sockets/chandelier) = 900 sockets

-- Now, in order to fill 900 sockets, we'll need 900 bulbs.

(900 bulbs) / (4 bulbs/box) = 225 boxes

If all the bulbs we buy are good ones, and we don't drop any while we're installing them, then we can just exactly do the job with <em>225 boxes</em>.

A ferry is travelling at 10 m/s relative to the river towards the south. The river is flowing at 2 m/s relative to
mixer [17]

Answer:

11 m/s south

Explanation:

The velocity of the passenger relative to the river bank is equal to the velocity of the passenger relative to the ferry, plus the velocity of the ferry relative to the river, plus the velocity of the river relative to the river bank.

v_passenger,bank = v_passenger,ferry + v_ferry,river + v_river,bank

If we take north to be positive and south to be negative:

v = 1.0 m/s + (-10 m/s) + (-2 m/s)

v = -11 m/s

v = 11 m/s south

A machine with a 5-N input force and a 25-N output force has a mechanical advantage of?
jolli1 [7]
So we want to know the mechanical advantage of a machine that has 5 N input force and 25 N out force. Mechanical advantage Ma is the measure of force amplification of some machine. We calculate it by taking the ratio of the output force Fo over the input force Fi. Ma=Fo/Fi=(25 N)/(5 N)=5. So Mechanical advantage for our machine is Ma=5 and the correct answer is the second one.
