The engineering design process is a series of steps that engineers follow when they are trying to solve a problem and design a solution for something; it is a methodical approach to problem solving. This is similar to the “Scientific Method” which is taught to young scientists.

A 2800 kg truck moving at 12 m/s to the right hits a stopped 1100 kg car. What is the combined velocity the moment they stick to

leva [86]

Answer:

The combined velocity is 8.61 m/s.

Explanation:

Given that,

The mass of a truck, m = 2800 kg

Initial speed of truck, u = 12 m/s

The mass of a car, m' = 1100 kg

Initial speed of the car, u' = 0

We need to find the combined velocity the moment they stick together. Let it is V. Using the conservation of momentum.

$m_1v_1+m_2v_2=(m_1+m_2)V\\\\V=\dfrac{m_1v_1+m_2v_2}{(m_1+m_2)}\\\\V=\dfrac{2800\times 12+0}{2800+1100}\\\\V=8.61\ m/s$

So, the combined velocity is 8.61 m/s.

Put each event in order of its occurrence, according to the big bang theory. please note that more accurate calculations of the

GalinKa [24]

I think the events are already chronologically arranged correctly. It always have to start with the simplest elements, the hydrogen and helium. In fact, these are the elements that compose the stars. The nuclear fusion of hydrogen atoms to helium is what gives the stars and the sun their energy. So, this is followed by letter b, which is the formation of stars. Then, when these stars explode a stated in c, they produce even heavier elements. As a result, this big bang theory tells us that the universe is expanding because of this 'explosion'. In the end, it led to the formation of the sun, the planets and the universe. <em>Thus, the arrangement is: a, b, c and d.</em>

Explain how mass is related to inertia.

seraphim [82]

Explanation:

The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

No, because the distance-time would show a constant velocity but the velocity-time graph shows an increasing velocity.

A circular loop of wire having a radius of 5.58 cm carries a current of 0.230 A. A vector of unit length and parallel to the dip

Sidana [21]

Answer:

see explanation

Explanation:

Given quantities:

radius = r = 0.0558 [m]

current = I = 0.23 [A]

$\vec{B} =$

Now we solve this by obtaining the torque acting on the dipole

$\tau = M \times B$

We obtain the magnetic moment vector M, first, |M| is defined as $M = IA$ , where A is the cross-section area of the loop which is $A = \pi r^2=\pi (0.0558)^2= 0.00978 [m^2]$ then
