Answer:
the charge per unit area on the plastic sheet is - 3.23 x 10⁻⁷ C/m²
Explanation:
given information:
styrofoam mass, m = 16 g = 0.016 kg
net charge, q = - 8.6 μC
to calculate the charge per unit area on the plastic sheet, we can use the following equation:
where
the force between the electric field
m = mass
g = gravitational force
where
q = charge
E = electric field
and
E = σ/2ε₀
where
ε₀ = permitivity
thus
mg = qσ/2ε₀
σ = (2mg ε₀)/q
= 2 (0.016) (9.8) (8.85 x 10⁻¹²)/( - 8.6 x 10⁻⁶)
= - 3.23 x 10⁻⁷ C/m²
kinematic equation
v=u+at
v-u=at
v-u = 1x5
the driver will have increased speed by 5 m/s. actual speeds unknown
The magnitude of the acceleration is 0.1038 m/s²
Explanation:
Net force is given by the square root of the sum of squares of the forces in y and x coordinates
Absolute Net Force will be;
However, Fnet can be calculated as the product of force and acceleration
Fnet=m*a
Fnet= 80.45 N
m= 775 kg
a=?
80.45=775*a
80.45/775= a
0.1038 m/s²=a
