<h2>Formulas For Impulse </h2>

Impulse is the variance of the momentum of a thing when the thing is operated upon by a force for an interval of time. Following are the possible formulas for impulse as;

Momentum is product of mass and velocity. According to newton’s second law, F =ma is by putting values of acceleration (a = ( vf - vi ) / t. Therefore, F =( m v ) / t. F t = m v and F t is impulse.

J = Ft

J = mv

J = p

Titanium is a metal used to make golf clubs. A rectangular bar of this metal measuring 1.96 cm x 2.19 cm x 2.63 cm was found to

masha68 [24]

$4.012\frac{gr}{cm^3}$

Explanation

the density of an object is given by:

$\text{Density(d)}=\frac{mass(m)}{\text{volume(v)}}$

Step 1

find the volume of the bar

a)find the volume of the rectangular bar.

the volume of a rectangular prism is given by:

$\text{Volume}=\text{ length}\cdot widht\cdot depth$

replace

$\begin{gathered} \text{Volume}=(\text{ 2.63}\cdot2.19\cdot1.96)(cm^3) \\ \text{Volume}=11.289012(cm^3) \end{gathered}$

Step 2

now,

Let

$\begin{gathered} \text{Volume}=11.289012(cm^3) \\ \text{mass}=\text{ 45.3 gr} \end{gathered}$

replace in the formula

$\begin{gathered} \text{Density(d)}=\frac{mass(m)}{\text{volume(v)}} \\ d=\frac{45.3\text{ gr}}{11.289012(cm^3)} \\ d=4.012\frac{gr}{cm^3} \end{gathered}$

therefore, the answer is

$4.012\frac{gr}{cm^3}$

How potential and kinetic energy changed during the spacecraft launches.

LenaWriter [7]

Answer:

Have a blessed day!

Explanation:

The energy to launch the spacecraft came from moving the spacecraft against the magnetic force. The energy used to move a magnet against a magnetic force is stored as potential energy in the magnetic field. This magnetic force can convert potential energy stored in the magnetic field to kinetic energy.
