Are there any options or is it not a multiple choice question.
Answer:
112J (3 s.f.)
Explanation:
KE= 1/2mv^2
where KE is kinetic energy, m is the mass in kg, and v is the velocity (or speed to take it simply) in m/s.
KE= 1/2(6)(6.1^2)
KE= 111.63
KE= 112J (3s.f.)
Answer: F = 3.28 × 10^-7 N
Explanation:
Alpha particle charge (q)= 2e
e = 1.6 × 10^-19
q = 2e = 2 × (1.6 *10^-19) = 3.2 × 10^-19
1/4πEo = 9 × 10^9
Distance(r) = 5.3 × 10^-11m
The force of attraction between the two particles is given by:
F = (1/4πEo) (q1q2 / r^2)
F = [(9 × 10^9) (3.2 × 10^-19) (3.2 × 10^-19)] / (5.3 × 10^-11)^2
F = (92.16 × 10^(9 - 19 - 19)) / 28.09 × 10^-22
F = (92.16 × 10^-29) / 28.09 × 10^-22
F = 3.28 × 10^(-29 + 22)
F = 3.28 × 10^-7 N
The primary reason of gender –
based violence is inequality of power. Second, cultural beliefs, norms and
practices are often used as an excuse to justify the violence experienced. And
thirdly, the idea of inferiority between men and women.
