Answer:
The slopes shows that the direction of the field is from -2 to +2, with three point charges, q₁, q₂ and q₃ at -2, 0 and +2 respectively.
Explanation:
Given;
The slope, dy/dx = 2x(y-6) - 4
2x(y-6) - 4 = 2xy - 12x - 4, divide through by 'x'
dy/dx = 2y -12 - 4/x
The slopes of the linear elements on the lines, x =0, y = 5, y = 6, y = 7.
At x = 0, and y = 5
dy/dx = 2y -12 - 4/x
dy/dx = 2(5) - 12 = -2
At x = 0, and y = 6
dy/dx = 2y -12 - 4/x
dy/dx = 2(6) - 12 = 0
At x = 0, and y = 7
= 2y -12 - 4/x
dy/dx = 2(7) - 12 = 2
Therefore, the slopes shows that the direction of the field is from -2 to +2, with three point charges, q₁, q₂ and q₃ at -2, 0 and +2 respectively.
Answer:
Explanation:
An electromagnetic wave can be created by accelerating charges; moving charges back and forth will produce oscillating electric and magnetic fields, and these travel at the speed of light.
Answer:
capillaries are 5.09 × 
Explanation:
Given data
area = 10.0 cm2
speed = 4.00
average diameter = 10.0 µm
to find out
total cross-sectional area and How many capillaries
solution
we apply here continuity equation
a1× v1 =a2 ×v2
we know v2 /v1 = a1/a2 that is equal 4
so here a1 will be
= 4 × 10
so a1 is 40 cm²
and capillaries are a1/ area
area = 
/4 × 10 ² ×
capillaries are = 40 ×
/ /4 × 10 ² ×
capillaries are 5.09 × [tex]10^{7}
Answer:
light is an example of a wave that is not mechanical .
it is different as it does not need material medium for its propagation
