Answer:
i hope it will be useful for you
Explanation:
F=5.6×10^-10N
R=93cm=0.93m
let take m1 and m2 =m²
according to newton's law of universal gravitation
F=m1m2/r²
F=m²/r²
now we have to find masses
F×r²=m²
5.6×10^10N×0.93m=m²
5.208×10^-9=m²
taking square root on b.s
√5.208×10^-9=√m²
so the two masses are m1=7.2×10^-5
and m2=7.2×10^-5
Answer:
Explanation:
It's equal to change of momentum in contact
Answer:
a) 9.81 m/s²
b) 5.22 m
Explanation:
Any object falling to the surface of Earth has a constant acceleration. It does not matter what the initial speed is the rate of change of velocity will be constant. The constant value is calculated by
g = Accleration due to gravity
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of Earth = 5.972 × 10²⁴ kg
r = Radius of Earth = 6.371×10⁶ m
Plugging all the values we get
g = 9.81 m/s²
The speed of the stone is increasing. Downward direction is considered as positive.
Time = t = 0.46 s
u = Initial velocity = 9.1 m/s
s = Displacement
Equation of motion
Distance travelled in 0.46 seconds is 5.22 m
Answer:
Explanation:
j = l + s , l is angular momentum quantum no and s is spin quantum number.
s = 1/2
j = l + 1/2
For j = 7/2
l = 3
l = 3 denotes f state
For j = 9/2
l = 4
l = 4 denotes g state.
I think it's because you shook all of the ingredients that were separating that make them settle back in order. when you shake more than one ingredient together, they will mix up evenly.
