Answer: The strength of an electric field is E = - 0,05.10⁹ N/C.
Step-by-step explanation: According to the question, the plastic sphere is in equilibrium in an electric field. This sugests that the forces acting on the sphere, which are Gravitational Force (Fg) and Electric Force (Fe) are also in equilibrium, denotating Fg=Fe.
As Fg = m . g, with m = 0,009kg and g= 9,8m/s², we have Fg = 0,0882N.
Knowing the value of Fe, the strength of the electric field can be calculated as
E = Fe/Q, in which Q is the electric charge.
E = (0,0882) / (-1,6·10⁻⁹)
E = - 0,05·10⁹N/C

Answer: 0.3
Step-by-step explanation:
The h(x) should be Left 4 units translated to the left or right to represent the same function d(x).
<h3>What is a function?</h3>
The function is a type of relation, or rule, that maps one input to specific single output.
Calculation of h(x) that need to be translated:
h(x) represents a line with slope 2.
Let's assume it has y-intercept b so,
h(x) = 2x + b
d(x) represent h(x) shifted up 8 units.
So,
d(x) = h(x) + 8
d(x) = 2x + b + 8
Now
h(x−a) = d(x)
2(x−a) + b = 2x + b + 8
2x − 2a + b = 2x + b + 8
-2a = 8
a = -4
Since a is negative, so the shift is to the left to represent the same function d(x) .
