16, 5 , 3 = 16+5+3= 24 + 3
So at the end put 24 + 3 cm
And put 16 for the lengths
For the value 5 and for the diving thingy 3
It is C because less than one percent of water is fresh water
The basic unit of energy is a joule. Kill calories measure the energy available in food.
Verrrrry interesting question !
Force= (mass) x (acceleration)
(49.5kg) x (1.3 m/s²) =
<u> Net</u> force on the box is <u>64.25 newtons upward</u>.
That's the <u>net</u> force. It's the combination of the tension in the rope
pulling the box up, and the force of gravity pulling the box down.
Force of gravity = "weight" = (mass) x (gravity) =
(49.5) x (9.8) = <u>485.1 newtons downward</u>
The tension in the rope must be enough to balance the downward force
of gravity PLUS provide another 64.25 newtons upward.
<em>Tension =</em> (485.1) + (64.25) = <em>549.35 newtons</em>
