Answer:
(a) 12.5 km
(b) 0 km
(c) 27.78 m/s
Explanation:
100 km/h = 100 km/h * 1000m/km * 1/60 h/minute * 1/60 minute/second = 27.78 m/s
7.5 minutes = 7.5*60 = 450 s
(a) Distance is speed times time duration
s = vt = 27.78 * 450 = 12500 m or 12.5 km
(b) As the car is moving in a circular track with circumference of 12.5 km. This means that after the car drives a distance of 12.5km, it's back to the initial point. So the total magnitude of the car displacement is 0 km
(c) 27.78 m/s
Answer:
E=1485.9N/C
Explanation: =
Electric field E=kQ/r²,
where k is a constant with a value of 8.99 x 10^9 N m²/C²
Q is the point charge
r is the distance between two point charges =0.44m
O=32*10^-9
Hence
E=(32*10^-9*8.99 x 10^9)/0.44²
E=32*8.99/0.1936
E=287.68/0.1936
E=1485.9N/C
Coulomb's law states that: The magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.
Answer:
Datos:
q1 = -50 μC = 
q2 = +30 μC = 
F = 10 N
a) x si la <em>F = 10N</em>
Aplicando la Ley de Coulomb:
x = 
= 
= 1,162m
b) x si la <em>F = 20 N</em>
x=<em> </em>
<em> </em>= 0,822m
c)x si la <em>F = 50 N</em>
x = 
= 0,520m
