Answer:
A. Their shape
Explanation:
The name clearly shows that the shape of these canals are semi-circular. The semi-circular canals consist of three tubes filled with fluid and located in the inner ear. They help to maintain balance and transmit impulses through the movement of the fluids. The impulses sent through these fluids are sent to the brain for interpretation.
The function of the canals are not indicated by the name, rather the shape is hinted through the name.
Answer:
v = 1.7 m/s
Explanation:
By applying conservation of energy principle in this situation, we know that:
Loss in Potential Energy of Car = Gain in Kinetic Energy of Car
mgΔh = (1/2)mv²
2gΔh = v²
v = √(2gΔh)
where,
v = velocity of car at top of the loop = ?
g = 9.8 m/s²
Δh = change in height = 45 cm - Diameter of Loop
Δh = 45 cm - 30 cm = 15 cm = 0.15 m
Therefore,
v = √(2)(9.8 m/s²)(0.15 m)
<u>v = 1.7 m/s</u>
Unless the ring by design will have restriction for any outward expansion. The hole will get larger / bigger as you heat this up. The more you heat an object the more it expands, thus the larger the hole gets. The only case is when outward expansion is restricted, the expansion will be inward as it is the only direction the ring can expand to.
Answer:
The distance from harvest mouse to the leaf is 4.74 m.
Explanation:
Given that,
Intensity = -10 dB
Distance = 1.5 m
We need to calculate the power of intensity
Using formula of power of intensity
Put the value into the formula
We need to calculate the minimum intensity level
Using formula of minimum intensity
We need to calculate the area
Using formula of intensity
Put the value into the formula
We need to calculate the distance
Using formula of area
Put the value into the formula
Hence, The distance from harvest mouse to the leaf is 4.74 m.
