Answer:
45.8 cm
Explanation:
To solve this, we will use the formula
5 / x² = 7/(1 - x)²
5 / x² = 7 / (1 - 2x + x²)
5 / 7 = x² / (1 - 2x + x²)
x = 0.5 * (√(35) - 5) meters
x = 0.5 * (5.916 - 5)
x = 0.5 * (0.916)
x = 0.458 or x = 45.8
Answer:
As we know that science is based upon logic. So the scientific theories have a logical reasoning behind them. So considering that in mind, scientific hypothesis include the motion of sailing rocks by animals, wind, flowing water, magnetic field, humans and gravity. The motion of the rocks by ghosts, God and magic are not scientific theories as we can not prove them logicaly.
Explanation:
Answer:
The horizontal distance is 136.6 m.
Explanation:
Given that,
Initial speed = 38 m/s
Angle = 34°
Suppose, Calculate the horizontal distance 
in meters the ball has traveled when it returns to ground level.
We need to calculate the horizontal distance
Using formula of range
Where, v= speed
g = acceleration due to gravity
Put the value into the formula
Hence, The horizontal distance is 136.6 m.
It must be the same force, because when it is applied, it is 'distributed' equally in each of the points (either a tendon or a wire or a rope or something similar). The 128N resistance should be preserved for tendons that have the same diameter.
Therefore the correct answer is A.
Answer:
The angle is 84.26⁰
Explanation:
The angle the axis of a polarizing filter need to make with the direction of polarized light is given by;
I = I₀Cos²θ
where;
I is the intensity of the polarized light transmitted from the polarizer
I₀ is the intensity of the polarized light incident on the polarizer
Given;
I₀ = 1.00 kW/m² = 1000 W/m²
I = 10 W/m²
Therefore, the angle is 84.26⁰
