stira [4]

Answer:

500,050000 years

Explanation:

Given that :

Rate of Accumulation = 3cm/ 1000 years

Height of seamounts = 1.5km

Representing height of seamounts in cm;

(1.5 *1000 * 100) = 1500150 cm

Time taken = height / rate

Time taken = (1500150 cm / 3cm) * 1000

Time taken = 500,050000 years

How have ideas about the atom changed in the last two centureies?
dsp73
In the past a scientist named dalton produced an atomic theory. There were certain problems regarding his views. So, later on scientists like chadwick, rutherford and thompson added some fresh light for the real identification of the atom.
dalton said the atom was the smallest unit and it CANNOT BE DIVIDED ANY FURTHER.
NOTE... this was renected with the discovery of the proton, neutron and electron as the sub atomic particles.

Help! ASAP! Please on the questions
KiRa [710]

Answer:

62.15 m (squared)

Explanation:

We know that the Area of the square is 5.5 x 4= 22

so 90 degree to 30 degree is divide by 3

so u divide 22 by 3 and get 7.3 wich is the semi circle thing

now 7.3 x 5.5 = 40.15

22 + 40.15 = 62.15 m (squared)

Look im not really sure but I think this is the answer

<em><u>Please mark as brainliest</u></em>

Have a great day, be safe and healthy

Thank u  

XD
