That's a formula that shows the relationship between three quantities ...
weight, mass, and acceleration.  If you know any two of them, then you
can use this formula to find the one you don't know.

Examples:

==>  I have a rock with 2 kilograms of mass.
        The gravitational acceleration on Earth is 9.8 m/s² .
        How much does my rock weigh on Earth ?

         Weight = (mass) x (grav acceleration)
                      = (2 kg) x (9.8 m/s²)
                                                       =  19.6 newtons
                                                  (about 4.41 pounds)

==>  My brother weighs 770 newtons (about 173 pounds) on Earth.
         What is his mass ?

                               Weight = (mass) x (grav acceleration)

                               770 newtons = (mass) x (9.8 m/s²)
Divide each side
by 9.8 m/s²:           770 newtons / 9.8 m/s² = mass

                                        78.57 kilograms = mass

==> When I went to the Moon, I took along my 2-kilogram rock.
         I weighed my rock on the Moon. 
         It weighs 3.25 newtons  (about 0.73 pound) there.
         What is the gravitational acceleration on the Moon ?

                                   Weight = (mass) x (grav acceleration)

                                   3.25 newtons = (2 kg) x (acceleration)

Divide each side
by  2 kilograms:        (3.25 newtons)/(2 kg)  =  acceleration

                                    1.63 m/s² = grav acceleration on the Moon

Provide examples of Thermodynamics.
vampirchik [111]
Thermodynamics is the branch of physical science which deals with the relationship between heat and other forms of energy like chemical energy, mechanical or electrical. Here are examples of thermodynamics that are commonly seen in everyday living: When you accidentally wrecked or bumped your car, you came out alive and just slightly hurt, because it was the car that that absorbed the energy of the impact. Another example is that, during cooking. When you are cooking, the heat is being transferred to the pan and then to the food that you are cooking.

Anna35 [415]

Answer:

w = 0.886 rad / s

Explanation:

Angular and linear variables are related

       a = α r

where a is the linear acceleration, α the angular acceleration and r the radius of gyration

         α = a / r

the angular velocity we can find it

         w² = w₀² + 2 α θ

the initial angular velocity is zero, the angles to be horizontal is

    θ = π/ 2  rad

     

we substitute

          w = √ 2 a / r  θ

we calculate

          w = √ (2 3/12 π/2)

          w = 0.886 rad / s

If u shine a light of frequency 375Hz on a double slit setup, and u measure the slit separation to be 950nm and the screen dista
xxMikexx [17]

Answer:

Y = 3.39 x 10⁶ m

Explanation:

We will use Young's Double Slit formula here:

Y = \frac{\lambda L}{d}

where,

Y = Fringe spacing = ?

λ = wavelength = \frac{speed\ of\ light}{frequency} = \frac{3\ x\ 10^8\ m/s}{375\ Hz} = 8 x 10⁵ m

L = screend distance = 4030 nm = 4.03 x 10⁻⁶ m

d = slit separation = 950 nm = 9.5 x 10⁻⁷ m

Therefore,

Y = \frac{(8\ x\ 10^5\ m)(4.03\ x\ 10^{-6}\ m)}{9.5\ x\ 10^{-7}\ m}

<u>Y = 3.39 x 10⁶ m</u>
