The answer to your question is true
Answer:
150 newtons
Explanation:
F = ma
force = mass * acceleration
the mass is 10 kg, and the accelration is 15 m/s^2
10*15 = 150
the force unit that matches with meters/second and kg is newtons
F =ma
150 newtons = 10 kg * 15 m/s^2
Answer: 38.2 μC
Explanation: In order to solve this problem we have to use the relationship for a two plate capacitor with a dielectric so:
C= Q/V= we also know that for two paralel plates C=εo*k*A/d and V=E/d
where k is the dielectric constant, A plate area, V is potential difference; E electric field and d the separation between the plates.
reorganizing we have:
Q/A=σ= E*k/εo= 1.2 * 10^6*3.6/8.85 * 10^-12=38.2μC
(1/2)(5.0)(v²) = 150
v= 7.75m/s
