Food

Consume local and seasonal products (forget strawberries in winter)

Limit meat consumption, especially beef

Select fish from sustainable fishing

Bring reusable shopping bags and avoid products with excessive plastic packaging

Make sure to buy only what you need, to avoid waste

Clothing

Take good care of your clothes

Try swapping, borrowing, renting or buying second-hand

Buy responsibly-made clothes, e.g. made from recycled material or with an eco-label

Transport

Cycle or use public transport

Be smart about when and how you drive

Try the train for your next holiday

Energy and waste

Turn down the heating by 1°, it will already make a difference

Take short showers

Turn off the water while you brush your teeth or clean the dishes

Unplug your electronic equipment and don’t leave your phone on charge when the battery is already full

Select energy efficient products with an “A” label (EU Energy Label)

Limit and recycle your waste

Answer:

Then the difference of weight between the two cars are:

Δw = 14210 - 5292 = 8918 N

Explanation:

An object's weigh due to the gravitational attraction force of the earth is:

w = mg

            Where: m is the object's mass

                         g is the  gravitational acceleration in the surface earth

                         g = 9.8 m/s2

The the ultralight car's weight is:

w_{uc} = (540)(9.8)

w_{uc} = 5292 N

And the Honda Accord's weight is:

w_{HA} = (1450)(9.8)

w_{HA} = 14210 N

Then the difference of weight between the two cars are:

Δw = 14210 - 5292 = 8918 N

The lawn sprinkler consists of four arms that rotate in the horizontal plane. The diameter of each nozzle is 8 mm, and the water
sashaice [31]

Answer: the constant angular velocity of the arms is 86.1883 rad/sec

Explanation:

First we calculate the linear velocity of the single sprinkler;

Area of the nozzle = π/4 × d²

given that d = 8mm = 8 × 10⁻³

Area of the nozzle = π/4 × (8 × 10⁻³)²

A = 5.024 × 10⁻⁵ m²

Now total discharge is dived into 4 jets so discharge for single jet will be;

Q_single = Q / n = 0.006 / 4 = 1.5 × 10⁻³ m³/sec

So using continuity equation ;

Q_single = A × V_single

V_single = Q_single/A

we substitute

V_single = (1.5 × 10⁻³) / (5.024 × 10⁻⁵)

V_single = 29.8566 m/s

Now resolving the forces as shown in the second image,

Vt = Vcos30°

Vt = 29.8566 × cos30°

Vt = 25.8565 m/s

Finally we calculate the angular velocity;

Vt = rω

ω_single = Vt / r

from the given diagram, radius is 300mm = 0.3m

so we substitute

ω_single = 25.8565 / 0.3

ω_single = 86.1883 rad/sec

Therefore the constant angular velocity of the arms is 86.1883 rad/sec

True or false: Ultimate tensile strength increases as the thickness of a solid material sample increases.
Varvara68 [4.7K]

Answer:

False.

Explanation:

Tensile strength should remain constant, regardless of thickness. For larger cross sections, it can slightly increase because the atoms in the center become more constricted and therefore less responsive to the applied stress.
