Answer:
Time taken by birdie’s trip = 1.2235 s (Approx)
Explanation:
Given:
Velocity = 4.25 m/s
Displacement = 5.2 m
Find:
Time taken by birdie’s trip = ?
Computation:
⇒ Time taken = Displacement / Velocity
⇒ Time taken by birdie’s trip = Displacement / Velocity
⇒ Time taken by birdie’s trip = 5.2 m / 4.25 m/s
⇒ Time taken by birdie’s trip = 1.2235 s (Approx)
Answer:
Explanation:
Given
Force = 8N
Direction = N50°E
Required
x component of the Force
Fx = F cos theta
Fx = 8cos 50°
Fx = 8(0.6428)
Fx = 5.1423N
Hence the x component of the force is 5.1423N

Answer:
995.12 N/C
Explanation:
R = 9 cm = 0.09 m
σ = 9 nC/m^2 = 9 x 10^-9 C/m^2
r = 9.1 cm = 0.091 m
q = σ x 4π R² = 9 x 10^-9 x 4 x 3.14 x 0.09 x 0.09 = 9.156 x 10^-10 C
E = kq / r^2
E = ( 9 x 10^9 x 9.156 x 10^-10) / (0.091 x 0.091)
E = 995.12 N/C
