Nitrogen has a half life of 10 days. If you have a 75 gram sample how much is remaining after 20 days ?

1 answer:

3 0

There is 9.375 g of nitrogen. This is because when a half-life passes, the mass becomes 2 times less. Since two half-lives have passed, you need to divide by 4.

Find the horizontal range of a projectile launched at 15 degrees to the horizontal with speed of 40m/s

vfiekz [6]

To Find :

The horizontal range of a projectile launched at 15 degrees to the horizontal with speed of 40 m/s.

Solution :

The horizontal range of a projectile is given by :

$R = \dfrac{u^2 sin 2\theta}{g}$ ( Here, g is acceleration due to gravity = 10 m/s² )

Putting all value in above equation :

$R = \dfrac{40^2 \times sin (2 \times 15)}{10} \ m\\\\R = \dfrac{1600 \times 1}{2\times 10} \ m\\\\R = 80 \ m$

Therefore, the horizontal range of projectile is 80 m.
