A force of 8.0 N is along x direction, another force of 6.0 N is along +y direction. If both forces are acting on a point object

Darya [45]

Answer:

Resultant force, R = 10 N

Explanation:

It is given that,

Force acting along +x direction, $F_x=8\ N$

Force acting along +y direction, $F_y=6\ N$

Both the forces are acting on a point object located at the origin. Let the resultant force of the object is given by R. So,

$R=\sqrt{F_x^2+F_y^2+F_xF_y\ cos\theta}$

Here $\theta=90^{\circ}$

$R=\sqrt{F_x^2+F_y^2}$

$R=\sqrt{8^2+6^2}$

R = 10 N

So, the resultant force on the object is 10 N. Hence, this is the required solution.

In the fall of 2002, a group of scientists at Los Alamos National Laboratory determined that the critical mass of neptunium-237

Llana [10]

The concepts required to solve this problem are those related to density, as a function of mass and volume. In turn, we will use the geometric concept defined for the volume.

The relationship between volume, density and mass is given under the function

$\rho = \frac{m}{V}$

Here,

m = Mass

V = Velocity

Rearranging for the Volume,

$V = \frac{m}{\rho}$

With our information the volume is

$V = \frac{60kg}{19.5g/cm^3 (\frac{10^3kg/m^3}{1g/cm^3})}$

$V = 3.0769*10^{-3}m^3$

Now the volume of sphere is expressed as

$V = \frac{4}{3} \pi r^3$

Here r is the radius of Sphere, then rearranging to find the radius we have

$r = \sqrt[3]{\frac{3V}{4\pi}}$

$r = \sqrt[3]{\frac{3(3.0769*10^{-3})}{4\pi}}$

$r = 0.0902m$

Therefore the radius of a sphere made of this material that has a critical mass is 9.02cm
