Answer:

Review each answer in the explanation part

Explanation:

Identify a problem or need = Aerospace engineers need a lightweight material to build a jet

Note: Identify a problem is related always with a need.

After identify the problem the next stage is the design

Design a solution = Engineers determine what features the material must have.

Note: The design process implies the choice of the materials and the proper numeric calculations.

Implement the solution = Engineers test a carbon - plastic compound in a wind tunnel.

Note: after the design, the following process is the built of the equipment and the different tests.

Evaluate the solution = The carbon-plastic compound is redesigned to save maximun energy.

Note: After testing, you enter a part of re-design that means making improvements to the already constructed.

Microwave ovens emit microwave energy with a wavelength of 12.3 cm. What is the energy of exactly one photon of this microwave r
Valentin [98]
The energy of a photon is proportional to the speed of light and inversely proportional to the wavelength. The constant of proportionality is Planck's constant, <span>6.626 * 10^-34 Js</span>

E = hc/ {wavelength} 
E = [ 6.626 * 10^-34 Js * 2.997 * 10^8 m/s ] / 0.124 m 
E = 1.60 * 10^-24 J

An automobile having a mass of 1,000 kg is driven into a brick wall in a safety test. The bumper behaves like a spring with cons
Nady [450]

To solve this problem it is necessary to apply the concepts related to the conservation of energy, specifically the potential elastic energy against the kinetic energy of the body.

By definition this could be described as

PE = KE

\frac{1}{2}kx^2 = \frac{1}{2}mv^2

Where

k = Spring constant

x = Displacement

m = mass

v = Velocity

This point is basically telling us that all the energy in charge of compressing the spring is transformed into the energy that allows the 'impulse' seen in terms of body speed.

If we rearrange the equation to find v we have

v = \sqrt{\frac{kx^2}{m}}

Our values are given as

m = 1000kg

k = 5.75*10^6N/m

x = 3.12*10^{-2}m

Replacing at our equation we have then,

v = \sqrt{\frac{kx^2}{m}}

v = \sqrt{\frac{(5.75*10^6)(3.12*10^{-2})^2}{1000}}

v = 2.3658m/s

Therefore he speed of the car before impact, assuming no energy is lost in the collision with the wall is 2.37m/s

Lena is playing with a remote-controlled car in her backyard. She knows that the car uses a wheel and axle to move. What is the
melomori [17]

Answer:

C. chemical energy from the batteries

Explanation:

Remote-controlled car or commonly called RC cars are toy vehicles that are controlled or propelled to move from a distance by a wire-connected remote that sends radiowaves to the receiver. According to this question involving the remote-controlled car Lena is playing with, a transmitter from the remote propels the wheel and axle to make the car move.

The car contains a battery cell that uses it's chemical energy as a source of power for the wheel and axle system. Hence, the chemical energy from the batteries of a remote-controlled car powers the wheel and axle to make the car move.
