An electric travel blanket uses a car's 12V supply. The current is 3A.

snow_lady [41]

For electrical devices . . .

   Power dissipated = (voltage) x (current) =

   (12 V) x (3.0 A) = 36 watts .

1 watt means 1 joule per second

   (36 joule/sec) x (60 sec/min) x (10 min) = 21,600 joules

boyakko [2]

Answer:

F= 25N
∆l=280cm
K=?
you apply the formula = K:F/∆l
= 0,089N/cm

A psychopathologist records the number of criminal offenses among teenage drug users in a nationwide sample of 1,201 participant

lara [203]

Answer:

Standard deviation = 3

Explanation:

Given

$N = 1201$

$SS = 10800$

Required

Determine the standard deviation

First, we need to determine the variance;

$Variance = \frac{SS}{N - 1}$

This gives:

$Variance = \frac{10800}{1201 - 1}$

$Variance = \frac{10800}{1200}$

$Variance = 9$

Know that:

$Variance = SD^2$

Where SD represents standard deviation

This gives

$9 = SD^2$

Take square root

$SD = \sqrt 9$

$SD = 3$

What is the difference between a graph of linear motion and a graph of harmonic motion?

fredd [130]

Hope this helps :)

When describing linear motion, you need only one graph representing each of the three terms, while projectile motion requires a graph of the x and y axes. Graphs of simple harmonic motion are sine curves. Circular motion is different from other forms of motion because the speed of the object is constant.
