Perform the following conversions.
a. 0.074 km to m
b. 24,600 μg to g
c. 4.9 × 107 μg to kg
d. 84 dm to mm

a. 74 km

b.  .0246g

c. = .049 kg

d.  8400mm

Explanation:

a. 0.074 km to m

1000 meters is 1 km

.074 km* 1000m /1 km = 74 km

b. 24,600 μg to g

10^6 ug is 1 gram

24600 ug * 1 g/ 1000000 ug = .0246g

c. 4.9 × 10^7 μg to kg

4.9 × 10^7 μg* 1 g/ 1000000 ug * 1kg/1000g  = .049kg

d. 84 dm to mm

84 dm * 100 mm/ 1dm = 8400mm

A.

we know that, 1km=1000m

B.

we know that, 1000000μg=1g

C.

we know that, 1000000000μg=1kg

D.

we know that ,100mm=1dm

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
