Answer:
Explanation:
a )
Force at the surface = FR
Value of g at height h = g( 1 - 2 h / R )
force at height h = F_R ( 1 - 2 h / R)
F_R / 2 = F_R ( 1 - 2 h / R)
= F_R - 2 F_R xh / R
F_R / 2 = 2 F_R x h / R
1 / 2 = 2h / R
4h = R
h = R / 4 . Ans
b )
Value of g at depth d = g( 1 - d / R )
force at depth d = F_R ( 1 - d / R)
F_R / 2 = F_R ( 1 - d / R)
= F_R - F_R xd / R
F_R / 2 = F_R x d / R
1 / 2 = d / R
2d = R
d = R / 2
Answer: No sure what to do
Explanation: points for points
Answer: the reaction force is the arrows push against the bow sting
Explanation:the two objects must react the same , bowstring and arrow.
Answer:
I = 0.25 [amp]
Explanation:
To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the current by the resistance.
V = I*R
where:
V = voltage [Volt]
I = amperage or current [amp]
R = resistance [ohm]
Since all resistors are connected in series, the total resistance will be equal to the arithmetic sum of all resistors.
Rt = 2 + 8 + 14
Rt = 24 [ohm]
Now clearing I for amperage
I = V/Rt
I = 6/24
I = 0.25 [amp]
Answer:
0.7
Explanation:
Reasoning The distance between adjacent crests is the wavelength l. Since the speed of each wave is v = 3.00 × 108 m/s and the frequencies are known, the relation v = fl can be used to determine the wavelengths. The equation v = fl applies to any kind of periodic wave.
