Answer:
1.0E46 grams in galaxy
1.0E36 mass
1.0E12 stars - dividing equations - or 1000 billion stars
Answer:
Explanation:
Width of slit a = 1 x 10⁻³ / 210
a = 4.76 x 10⁻⁶ m .
angle at which first order peak is formed
= λ / a (where λ is wavelength and a is width of slit)
given λ = 506 x 10⁻⁹ m
a = 4.76 x 10⁻⁶
θ = 506 x 10⁻⁹ / 4.76 x 10⁻⁶
= 106.3 x 10⁻³ radian .
first order peak is formed at an angle of 106.3 x 10⁻³ radian .
there are a reading of something like s-waves and p-waves they tell if an earthquakes coming.
Answer:
Speedometer.
Explanation:
If you look at the speedometer in a car, you will see your instantaneous speed. Speedometers tell you your speed of that moment and thats what instantaneous speed.
