An object has a mass of 2,000kg. what is its weight on earth? show your work

2 answers:

6 0

Answer:

F=m*g is the formula and the answer is 19,620 kg

Explanation:

Since the formula is F=m*g and Earth's gravity is 9.81 m/s^2 all you need to do is multiply 2,000 by 9.81

Answer:

$20,000\:\mathrm{N}$

Explanation:

The weight of an object on Earth is equal to the force of gravity on that object.

We can use the following equation to determine the force of gravity on an object:

$F_g=ma_g=mg$ , where $m$ is the mass of the object and $g$ is acceleration due to gravity ( $9.81\: \mathrm{m/s}$ ).

Solving, we get: $F_g=2,000\cdot9.81=19,620=\fbox{$20,000\:\mathrm{N}$}$ (one significant figure).

Answer:

1:04-1:10 hours

Explanation:

You'll need a <em>Recreational dive planner</em> table, I annexed a copy, now you'll follow the next steps:

In the first part of your table, you'll look for the distance row (in feet) of your first dive, for this specific exercise you'll find 60, once you locate it you'll go down that column until you reach the time you'll dive, in this case, 45 (minutes) or the closest value (47).
You'll check and keep the letter in that 47 row (S) for future use.
Now you have to go to the second part of your table and look for the distance column, in feet, of your second dive. We find 60 and then going right in the blue row, we'll look for the time (35) or its closest value (36).
Finally, we have to check the letter for 36 minutes (F) and we'll make it met with the letter S in the first portion of your tables. This will give us an interval of time, 1:04-1:10 in this case.

I hope you find this information useful and interesting! Good luck!
