It will be lighter, as water is more heavier then others may think, a boat would weigh less since a chunk of water would most likely weigh 100 tons more.

Explanation:

percentage abundance of third isotope = 100 - ( 78.900 + 10.009)

= 11.091 %

Atomic mass

24.1687 x .789 + 25.4830 x .10009 + 24.305 x .11091

19.069 + 2.5506 + 2.69566

If I want to accelerate a mass of 3 kg at 5 m/s2 then how much force should I apply?

Stolb23 [73]

<u>Answer:</u> The force that must be applied is 15 N.

<u>Explanation:</u>

Force exerted on the object is defined as the product of mass of the object and the acceleration of the object.

Mathematically,

$F=m\times a$

where,

F = force exerted = ?

m = mass of the object = 3 kg

a = acceleration of the object = $5m/s^2$

Putting values in above equation, we get:

$F=3kg\times 5m/s^2=15N$

Hence, the force that must be applied is 15 N.
