Answer:
No there won't be.
Explanation:
An insulator does not conduct electricity readily. An insulator that is charged at one end will have the charges remain at that end, since it does not allow the free flow of charges through it. If you touch the other end of the insulator that is void of electric charges, there would be no charge transfer between you and the insulator, and hence no electric shock.
When the igneous rock is deep underground
for many years, it will form into metamorphic rock under extreme pressure and
temperature. It could also form into magma when it melts deep beneath the
layers of earth or it could form sediments when subjected to weather erosion.
<span>Relative frequency histograms are important because the heights can be interpreted as probabilities. These probability histograms provide a graphical display of a </span>probability distribution<span>, which can be used to determine the likelihood of certain results to occur within a given population.

To see the difference between frequency and relative frequency we will consider the following example. Suppose we are looking at the history grades of students in 12th grade and have the grades: A, B, C, D, F. The number of each of these grades gives us a frequency for each class:
<span>7 students with an F
9 students with a D
18 students with a C
12 students with a B
<span>4 students with an A
</span></span>
To determine the relative frequency for each class we first add the total number of data points: 7 + 9 + 18 + 12 + 4 = 50. Next we, divide each frequency by this sum 50.
<span>0.14 = 14% students with an F
0.18 = 18% students with a D</span><span>0.36 = 36% students with a C
0.24 = 24% students with a B
<span>0.08 = 8% students with an A
You can see it is very easy and convinient to analyse the data </span></span>
Answer:
125 m
Explanation:
Given:
v₀ = 20 m/s
v = 0 m/s
a = -1.6 m/s²
Find: Δy
v² = v₀² + 2aΔy
(0 m/s)² = (20 m/s)² + 2 (-1.6 m/s²) Δy
Δy = 125 m
