B. By vibrations in wires or strings
Answer:
<em>108</em>
Explanation:
<u>Proportions
</u>
Two quantities are proportional when one of them can be obtained by multiplying or dividing the other by a constant value. For example, knowing the price of one pencil as p, we can know the cost of purchasing X pencils as C=p.X
We are required to increase 90 by the ratio 6:5. The new value will be proportional to the original because we'll compute the product of

So the new value is 108

Answer:
Explanation:
In an electric field E force on charge q
F = Eq , acceleration a = Eq / m
a = 664 x 1.6 x 10⁻¹⁹ / 1.67 x 10⁻²⁷
= 636.16 x 10⁸ m /s²
b )
initial velocity u = 0
final velocity v = 1.46 x 10⁶ m/s
v = u + at
1.46 x 10⁶ = 0 + 636.16 x 10⁸ x t
t = 2.29 x 10⁻⁵ s
c )
s = ut + 1/2 a t²
= 0 + .5 x 636.16 x 10⁸ x ( 2.29 x 10⁻⁵ )²
= 1668 x 10⁻²
= 16.68 m
d )
Kinetic energy = 1/2 m v²
= .5 x 1.67 x 10⁻²⁷ x ( 1.46 x 10⁶ )²
= 1.78 x 10⁻¹⁵ J .
