During take-off a 8kg model rocket is burning fuel causing its speed to increase
77julia77 [94]

The strength of the thrust is 122 newtons.

The motion of the rocket is described by the second Newton's law, whose model is shown below:

\Sigma F = F - D = m\cdot a (1)

Where:

  • F - Thrust, in newtons
  • D - Drag, in newtons
  • m - Mass of the rocket, in kilograms
  • a - Net acceleration of the rocket, in meters per square second

If we know that D = 90\,N, m = 8\,kg and a = 4\,\frac{m}{s^{2}}, then the strength of the thrust is:

F = D + m\cdot a

F = 90\,N + (8\,kg)\cdot \left(4\,\frac{m}{s^{2}} \right)

F = 122\,N

The strength of the thrust is 122 newtons.

What is the spring constant (in n/m) of a spring that stores 100 J of elastic potential energy when it is stretched 5 m?
kogti [31]

Answer:

8N/m

Explanation:

The elastic potential energy stored can be calculated using the equation:

elastic potential energy = 0.5 × spring constant × (extension)2

assuming it is not stretched beyond the limit of proportionality.

Then calculate using the values in the question:

100J = 0.5 × spring constant × 5²

200J = spring constant × 25

spring constant = 200J ÷ 25m²

spring constant = 8J/m²

spring constant = 8N/m

Technician A says that daytime running lights (DRLs) light the headlights, usually at reduced intensity, whenever the engine is
miskamm [114]

Answer:

technician A is right

Explanation:

Daytime running lights are auxiliary lights that allow other cars to see us better. They are not intended to illuminate the road, so their intensity is low.

Consequently technician A is right

HID lights are high intensity lights, generally bluish-white in color, yellow lights are halogen lights with lower intensity than HID lights.

Consequently, technician B is wrong
