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)

Two boys with masses of 40 kg and 60 kg stand on a horizontal frictionless surface holding the ends of a light 10-m long rod. Th
zlopas [31]

When they meet the 40-kg boy would have moved a distance of 6 m.

<h3>Distance moved by the 40 kg boy</h3>

Apply the principle of center mass;

Take the 40 kg mass as the reference point;

X(40 kg) = (40kg x 0  + 60kg x 10 m)/(40 kg + 60 kg)

X(40 kg) = (600)/(100)

X(40 kg) = 6 m

Thus, when they meet the 40-kg boy would have moved a distance of 6 m.

Find an expression for the square of the orbital period.
jenyasd209 [6]

Answer:

T²= 4π²R³/GM

Explanation:

First we know that

Fg= Fc

Because centripetal force must equal gravitational force

So

GMm/R² = Mv²/R

But velocity is 2πR/T

So by substitution we have

GMm/R²= M (2πR/T)/T

We have

T²= 4π²R³/GM as period

Light of wavelength 530.00 nm is incident normally on a diffraction grating, and the first‑order maximum is observed to be 33.0∘
GarryVolchara [31]

Answer:

1028 slits/mm

Explanation:

We are given that

Wavelength of light, \lambda=530nm=530\times 10^{-9} m

1nm=10^{-9} m

\theta=33^{\circ}

n=1

We have to find the number of slits per mm are marked on the grating.

We know that

dsin\theta=n\lambda

Using the formula

dsin33^{\circ}=1\times 530\times 10^{-9}

d=\frac{530\times 10^{-9}}{sin33^{\circ}}

d=9.731\times 10^{-7} m

1m=10^{3}mm

d=9.731\times 10^{-7}\times 10^3mm

d=0.0009731mm

Number of slits=\frac{1}{d}

Number of slits=\frac{1}{0.0009731}/mm

Number of slits=1028/mm

Hence, 1028 slits/mm are marked on the grating.
