Hey there :)

Question: How many km are in 5.6mm?

=>5.6x10^3

=>5.6x10^-6

=>5.6x10^-3

=> 5.6x10^6

Answer:-

$5.6 \times 10^{ - 6}$

Explanation:-

By using the formula-

$1millimeter = \frac{1}{1000000}$

As 1 with 6 zeros, we convert it into exponential form.

$= > \frac{1}{10^{6} }$

As this above value is fraction type, we can do the reciprocal, thus, the exponent gets a negative value.

$= > 10^{ - 6}$

Now combine with given question.

$= > 5.6 \times 10^{ - 6}$

List the 3 types of organisms and how they each get their energy. * jejdjsjx pls hurryyyl

Helen [10]

Answer:

The three types of organisms in an ecosystem are producers, consumers, and decomposers.

Producers get their energy by using sunlight to make their own food from water and carbon dioxide through photosynthesis.

Consumers get their energy by eating plants and animals for food as they cannot make their own food.

Decomposers get their energy by eating/scavenging and breaking down dead and decaying plant and animal bodies.

Hope that helps.

Answer:

N=3.05*10^-3g

Explanation:

Using Ln(No/N)=0.693/t½*t

Ln(No/N)=0.693/3*45

No/N=exp(10.396)

100/exp(10.396)=N

100/32695.7=N

N=3.05*10^-3g
