Answer:
Use Fc centripetal force as positive and W the weight as negative
N = m v^2 / R + m g
v^2 = (N - m g) R / m
v^2 = (995 - 57 * 9.8) 42.7 / 57 = 327 m^2/s^2
v = 18.1 m/s
Note: N - m g is the net force producing the centripetal force
The primary force would be Thermal Convection, it pushes it and thus makes continents drift.

The "pitch" of a sound is the impression your brain forms
that corresponds to the frequency of the sound wave.
When the frequency is high, your brain says "high pitch".
When the frequency is low, your brain says "low pitch".
<h3><u>Given</u><u>:</u><u>-</u></h3>

<h3><u>Solution:-</u><u> </u></h3>

★ Substituting the values in the above formula,we get:



Answer:
a) 
b) a = 5.59 m/s²
Explanation:
given,
total distance traveled by the car to stop is 56.9 m when speed of vehicle is 80 km/h or 80 × 0.278 = 22.24 m/s
total distance traveled by the car to stop is 25.7 m when speed of vehicle is 50.7 km/h or 50.7 × 0.278 = 14.09 m/s
using stopping distance formula
................(1)
..............(2)
on solving both the equation we get


a = 5.59 m/s²
now reaction time calculation
