Question

A-1GB 667MHz DDR2 Non-ECC CL5 DIMM - $19

B-2GB 667MHz DDR2 Non-ECC CL5 DIMM - $35

For maximum efficiency should I purchase 2 – 1GB DIMM for a total of $38, or 1 – 2GB DIMM for $35. Note the price and speed is approximately the same. Discuss your thoughts.

Answer #1

Having less sticks of RAM chip on the motherboard is always preferrable since switching on to multiple chips for stored RAM data put more strain on the memory controller and data buses. It would take slightly longer for CPU to add and retrieve data from 2 sticks rather than one stick but it will not cause any significant performance difference to the user. Moreover, if you use 1 2-Gb Ram then you would have another slot vacant for future if you ever want to upgrade Ram further.

I will advise you to go for 1 2GB Ram chip. It's cheaper too.

19. A place kicker must kick a football from a point 35 m (about
38 yd) from the goal, and the ball must clear the crossbar, which
is 3.05 m high. When kicked, the ball leaves the ground with a
speed of 23 m/s at an angle of 51◦ to the horizontal. By how much
does the ball clear or fall short of clearing the crossbar? The
acceleration of gravity is 9.8 m/s 2 . Answer in units of m....

A lens of focal length 45 mm is mounted on a 35-mm camera. The
lens aperture is set at f/2.0 and the shutter speed set at 1/2000
s. The photographer wants to keep the same exposure (amount of
light), but wants to change the f-number to f/8.0 for greater depth
of field. What should be the new shutter speed to maintain the same
exposure? Please show steps so I can understand the problem.
