An object of mass m moves in one dimension with velocity given by v a/x for a a constant. Find the force on the object as a func

tion of position and the position time. To find the force, you may use either Newton's 2nd law or energy conservation. Assume that the object is initially at the origin.

Answer:

F = -m\frac{a^2}{x^3}

Explanation:

As we know that velocity as a function of position is given as

v = \frac{a}{x}

now in order to find the acceleration we can use that rate of change in velocity is known as acceleration

So we will have

a = \frac{dv}{dt}

a = \frac{d}{dt}(\frac{a}{x})

a = -\frac{a}{x^2}\frac{dx}{dt}

a = - \frac{a^2}{x^3}

Now by Newton's 2nd law we have

F = ma

F = -m\frac{a^2}{x^3}

levacccp [35]

Answer:

Q = 8,345 * v

Explanation:

So, we are looking for an expression of the amount of water that has been drained from the tub. The expression is in terms of v that represent the number of gallons of water drained since the plug was pulled. Since we are interested in the pounds of water that has been drained from the tub we need to take into account that for every gallon of water drained, 8.345 pounds have left the tub. Therefore, the expression for the weight of water Q that has been drained from the tub in terms of v is simply :

Q = 8,345 * v

Where v is the amount of gallons that has been drained from the tub.

No
For example a rock was broken into one big and one little piece. The properties of these 2 pieces are still the same even though they have different shapes.

Why are the element from period 2 grouped together
valentinak56 [21]
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. As you move down the table, every row adds an orbital.
