Answer:
If the earth stops rotating the apparent weight will increase at most of the places because the upward component of the centrifugal force due to rotation will disappear.
Answer:
Explanation:
Given
Diameter(D)=21.5 cm
distance between plate=1.75 mm
and we know capacitance is
and we know charge is
Q=CV
and charge density (![\sigma [tex])[tex]=\frac{Q}{A}=\frac{\epsilon _0AV}{Ad}=\frac{\epsilon V}{d}](https://tex.z-dn.net/?f=%5Csigma%20%5Btex%5D%29%5Btex%5D%3D%5Cfrac%7BQ%7D%7BA%7D%3D%5Cfrac%7B%5Cepsilon%20_0AV%7D%7BAd%7D%3D%5Cfrac%7B%5Cepsilon%20V%7D%7Bd%7D)

Answer:
a) Suzie’s average acceleration = -6.46 m/s²
b) Force exerted to stop Suzie = 271.52 N
Explanation:
a) We have equation of motion, v = u + at
Final velocity, v = 0 m/s
Initial velocity, u = 32 mph = 14.22 m/s
Time, t =2.2 s
Substituting
0 = 14.22 + a x 2.2
a = -6.46 m/s²
Suzie’s average acceleration = -6.46 m/s²
b) Mass of Suzie = 42 kg
Force = Mass x Acceleration
F = Ma
F = 42 x -6.46 =-271.52 N
Force exerted to stop Suzie = 271.52 N
