Light travels in a vacuum at a speed of 3.00 × 108 m s-1 .(a) Convert this speed to miles per second.(b) Express this speed in furlongs per fortnight, a littleused unit of speed. (A furlong, a distance used in horse racing, is 660 ft; a fortnight is exactly 2 weeks.)
Express the answers to the following calculations inscientific notation:(a) 145.75 + (2.3 × 10−1)(b) 79,500 ÷ (2.5 × 102)(c) (7.0 × 10−3
) − (8.0 × 10−4)
(d) (1.0 × 104
) × (9.9 × 106)
For each box, examine the blocks attached to the balances. Based on their positions and sizes, determine which block is more dense (the dark block or the lighter-colored block), or if the relative densities cannot be determined. (Think carefully about the information being shown.)
