First, we calculate the total are:
Area = 15 x 20
Area = 300 sq ft
Snowflakes accumulated per minute = 1150 x 300
Snowflakes per minute = 345,000 snowflakes per minute
Snowflakes per hour = 345,000 x 60
Snowflakes per hour = 20,700,000
Snowflakes per hour = 20.7 x 10⁶
Mass of one snowflake = 2.2 mg
Mass of one snowflake = 2.2 x 10⁻³ g
Mass of one snowflake = 2.2 x 10⁻⁶ kg
Mass of snow = 20.7 x 10⁶ x 2.2 x 10⁻⁶
Mass of snow = 45.54 kg per hour
Answer:
<em>Uses energy: Amoeba and clock both use energy</em>
<em>Contains cells: true for the amoeba.</em>
<em>Lacks genetic material: true for a clock.</em>
<em>Reproduces: True for amoeba</em>
<em>Has internal organization: True for amoeba and clock both</em>
<em> </em>
Amoeba can be described as a single-celled organism and hence is a living thing. It will show characteristics of a living thing. Whereas, a clock can be described as a device to watch time. It is a non- living thing.
The total number of protons and neutrons in an atom is called the mass number. You can find the mass numberfor any element. The mass number canbe found by rounding the average atomic mass to the nearest whole number.
as an example
6.25 is closer to 6 than 7 so it is 6
6. 50 is closer to 7 so it is 7
you have to look at the thenth digit. if the number is 4 or less you have to round it down
if the tenth digit is 5 or greather than you have to round it up.
