A 175-kg motorcycle goes around an unbanked turn of radius 75.4 m at a steady 112 km/h. Determine its acceleration?

Nuetrik [128]

Answer: $12.83 m/s^{2}$

Explanation:

In this case we are talking about the centripetal acceleration $a_{c}$ , which can be calculated by:

$a_{c}=\frac{V^{2}}{r}$

Where:

$V=112 \frac{km}{h} \frac{1000 m}{1 km} \frac{1h}{3600 s}=31.11 m/s$ is the speed of the motorcycle

$r=75.4 m$ is the radius of the path the motorcycle is going around

Solving:

$a_{c}=\frac{(31.11 m.s)^{2}}{75.4 m}$

Finally:

$a_{c}=12.83 m/s^{2}$

A nautical mile is 6076 feet, and 1 knot is a unit of speed equal to 1 nautical mile/hour. How fast is a boat going 8 knots goin

mezya [45]

Answer:

The speed of the boat is equal to 13.50 ft/s.

Explanation:

given,

1 nautical mile = 6076 ft

1 knot = 1 nautical mile /hour

1 knot = 6076 ft/hr

speed of boat = 8 knots

8 knots = 8 nautical mile /hour

= $8 \times \dfrac{6076\ ft}{1\nautical\ mile}\times \dfrac{1\ hour}{60\times 60\ s}$

= 13.50 ft/s

The speed of the boat is equal to 13.50 ft/s.

The cochlea is a hollow, spiral-shaped bone found in the inner ear that plays a key role in the sense of hearing . Sound waves are transduced into electrical impulses that can be interpreted by the brain as individual frequencies of sound.

so the ans should be-It sends information to the nerve due to fluid vibrations.

hope this helps please mark as brainliest:)
