<em>math</em><em>ematically</em><em>,</em>

<em>pressure =  \frac{force}{area}</em>

<em>but</em><em> </em><em>weigh</em><em>t</em><em>=</em><em> </em><em>Force</em><em>.</em>

given pressure

18N/cm^2

and <em>Force</em> = 9000N

making <em>area</em> the subject in the relation above.

Area =  \frac{force}{pressure}

substitute their values into the equation

Area =  \frac{9000}{18}

Area = 500 {cm}^{2}

A pillow with mass of 0.3 kg sits on a bed with a coefficient of static friction of 0.6. What is the maximum force of static fri
lys-0071 [83]
The maximum force of static friction is the product of normal force (P) and the coefficient of static friction (c). In a flat surface, normal force is equal to the weight (W) of the body. 
 
                        P = W = mass x acceleration due to gravity
    
                    P = (0.3 kg) x (9.8 m/s²) = 2.94 kg m/s² = 2.94 N

Solving for the static friction force (F), 
                                              F = P x c 
 
                                      F = (2.94 N) x 0.6 = 1.794 N

Therefore, the maximum force of static friction is 1.794 N.

An AC source is connected to a series combination of a light bulb and a variable capacitor. If the capacitance is increased, the
notsponge [240]

Answer:

Increases

Explanation:

Since power P=IV

Then it means when current increases, the power increases hence brightness increases. I represent current, P is power and v is voltage.

Current of capacitor when in series connection is given by

I=2\pi fCV

where I is current across capacitor, f is frequency, C is capacitance and v is voltage across capacitance. From this second formula, it is evident that an increase in capacitance increases the current across the capacitor. Therefore, if current increases, power also increases leading to an increase in brightness
