Randomly take 4 cards from a deck of 52 cards, find the probability that the 4 cards are all aces

kompoz [17]

You would divide the number of aces in a deck, which is 4, ny 52 which will give you about 0.0769. As a percentage it will be 7.69%. Round it off to 7.7% if you like. It’s either 7.7% it 7.69%.

The force F of gravity on a rocket varies directly with its mass m and inversely with the square of its distance d from Earth. W

xz_007 [3.2K]

Model for the Combined variation is $F = \frac{km}{d^{2} }$

Equation to find the mass of the rocket in terms of F and d is :

$m=\frac{F d^{2} }{k}$

<h3>What is Force ?</h3>

A force is the quantity that change the motion of the object. Force is that influence which can cause any object having some mass, to change it's position or to accelerate from it's original position.

Force (F) and mass (m) of any object are directly proportional to each other. More the mass of the object , more the force will require to accelerate it.

Mathematically, we can write the equation of force as :

F = m . a

where , m = mass of the object

a = constant value

In the statement given,

As, force of gravity varies directly with its mass

Therefore, F= k m , where k is a constant

Also force is inversely varies with square of distance d

Thus, F = k / d²

Combining both equations :

$F = \frac{km}{d^{2} }$

and the equation of mass in terms of F and d can be written as :
