Earthquakes generate two types of waves p waves and s waves. p waves travel through solids liquids and gasses. s waves travel through only solids.
Given :
Initial speed , u = 0 m/s .
Final speed , v = 91 km/h = 25.28 m/s .
To Find :
a) Average acceleration .
b ) Assuming the motorcycle maintained a constant acceleration, how far is it from the traffic light after 3.3 s .
Solution :
a )
We know ,by equation of motion :
b)
Also , by equation of motion :
Hence , this is the required solution .
Answer:
9.216 x 10^-8 N
Explanation:
q1 = 1.6 x 10^-19 C
q2 = - 1.6 x 10^-19 C
r = 5 x 10^-11 m
(a) The electrostatic force is given by
F = k q1 q2 / r^2
F = ( 9 x 10^9 x 1.6 x 10^-19 x 1.6 x 10^-19) / (5 x 10^-11)^2
F = 9.216 x 10^-8 N
This force is attractive in nature, as both the charges are opposite in nature.
Answer:
option A
Explanation:
steel in a conducting ball of diameter
2 r = 1 '' = 2.54 cm = 2.54 × 10⁻² m
Potential due to conducting steel ball
C = 0.1411 × 10⁻¹¹ Farad
C = 1.411 × 10⁻¹² Farad
C = 1.4 pF
Hence, correct answer is option A
