The force on one end of the trough is 5.4 X 10⁵ N
<u>Explanation:</u>
The triangle is equilateral which means all the interior angles are 60° and the sides are 6m long.
According to the figure,
AI / 8 = sin (60) = √3/2
AI = 4√3
The depth of the water is AI = 4√3
The interval becomes, | 0 , 4√3|
w = 2JK
(the hydrostatic force acting on the strip is the product of the pressure and the area)
where.
ρ = 875 kg/m³
g = 9.8m/s²
d = depth ( d = y')
limit is 0 → 4√3
On solving the equation, we get the value of limit as 32√3
Therefore, the force on one end of the trough is 5.4 X 10⁵ N
Explanation:
The energy of a wave is given by :
Where
h is Planck's constant
c is the speed of light
is wavelength
Energy is inversely proportional to wavelength. Also, the relation between frequency and wavelength is inverse.
If the frequency is high, the wavelength will be shorter.
Hence, the correct options are :
Higher frequencies have shorter wavelengths.
Shorter wavelengths have lower energy.
Lower frequencies have lower energy.
Answer:
Explanation:
As we know that the gravitational force between two masses is given as
here we know that
also we know that
so the force between two masses is given as
<span>Force between the balls is:
at 15 m : F(15) = G*500*75/15^2 = G*37500/225
at 20 m : F(20) = G*500*75/20^2 = G*37500/400
Then the ratio will be F(15)/F(20) = (G*37500/225)/(G*37500/400) = 400/225 = 16/9
Solution: Ratio is B) 16/9</span>

so i believe your answer is abt 1800-2400
Explanation:
According to the Dietary Guidelines for Americans 2010, sedentary teen girls between the ages of 13 and 18 need 1,600 to 1,800 calories per day, while active girls require 2,200 to 2,400 calories each day
