To calculate the density of an object you use the density formula which is:

D=m/v

now we plug in what we're given.

m=25.0g
v=49.10mL-45.50mL=3.6mL

D=25.0g/3.6mL=6.9 g/mL

The density of the iron is 6.9 g/mL. (btw, I left the answer in significant figures)

If distance, d, is proportional to time, t, and at time t =2.00 seconds, the distance is 6.20 m, find the distance when t = 3.50
Allushta [10]
At 3.5s the distance would be 10.85

Find 1/4th of 2.00 and add that to 6.2

some infrared radiation reaches earth and sum does not with part does reach earth longer wave length or short wave length
Ede4ka [16]
The answer is long wave length because long wave lengths contians less energy, and would not harm living things such as plants and animals. the more engey a wave length has, the less harmful it is.

short wave length: lots of energy, extremely hot. (examples: gamma rays, and UV (ultraviolet) rays.

long wave lengths: not much energy, safe for humans and other life on Earth.

hopefully this helps.
