A common technique in analysis of scientific data is normalization. The purpose of normalizing data is to eliminate irrelevant c

nataly862011 [7]

Answer:

V₂ = 0.4432

Explanation:

The normalize procedure is widely used in science, in this case we are going to normalize to the voltage value that exists 4 cm away

Vₙ= V_{measured} / V₀

where the voltage at the desired distance is V₀ = 185 mV = 0.185 V

the normalized voltage are

forr x = 4 cm

V₁ = 185/185

V₁ = 1

for x = 6.2 cm

V₂ = 82/185

V₂ = 0.4432

Diano4ka-milaya [45]

Answer:

to have courage and show the strength of your character. ... A person with true grit has passion and perseverance. Goals are set and followed through.

Explanation:

for example: i had the passion and the courage to finish my school work and chores for i can go out with my friends and to get out of the house for a bit and have fun so i had the courage to finish chores from the house and do some schoolwork for i can finish ad hang out with some friends. so i had the strength to finish everything because i didn't want to be doing school work and chores any more so i had the passion to finish up quickly

A 55.6-kg skateboarder starts out with a speed of 2.44 m/s. He does 80.4 J of work on himself by pushing with his feet against t

Vikentia [17]

(a) -1620.8 J

The initial kinetic energy of the skateboarder is:

$K_i = \frac{1}{2}mu^2 = \frac{1}{2}(55.6 kg)(2.44 m/s)^2=165.5 J$

where m is the skateboarder's mass and u his initial speed;

While the final kinetic energy is

$K_f = \frac{1}{2}mv^2 = \frac{1}{2}(55.6 kg)(7.24 m/s)^2=1457.2 J$

where v is his final speed.

So the change in kinetic energy is

$\Delta K=K_f - K_i = 1457.2 J -165.6 J = 1291.6 J$

According to the work-energy theorem, the change in mechanical energy (kinetic+potential) of the skateboarder is equal to the work done on it:

$\Delta K + \Delta E_p = W + W_f$

where

$W = 80.4 J$ is the work done by the skateboarder on himself

$W_f = -244 J$ is the work done by friction

$\Delta E_p = E_p_f - E_p_i$ is the change in gravitational potential energy

Solving for $\Delta E_p$ ,

$\Delta E_p = W+W_f - \Delta K=80.4 J - 244 J - 1457.2 J = -1620.8 J$

(b) 2.97 m

The change in potential energy of the skateboarder can be written as

$\Delta E_p = mg \Delta h$

where

m = 55.6 kg is the mass

g = 9.8 m/s^2 is the acceleration of gravity

$\Delta h$ is the change in vertical height of the skateboarder

Solving for $\Delta h$ ,

$\Delta h = \frac{\Delta E_p}{mg}=\frac{-1620.8 J}{(55.6 kg)(9.8 m/s^2)}=-2.97 m$

Where the negative sign means the skateboarder has moved downwards. Since we are interested only in the absolute value, the answer is

h = 2.97 m

How are matter and substances related?

Sedbober [7]

Matter is anything that has mass and takes up space. Substances are types of matter that are pure. Just remember that matter has mass and they both start with "m." Substances are <u>types of matter</u>. Cheers, mimiisawesome5
