Answer:

paying bills online instead of sending paper through the mail

Explanation:

In today's era everyone is aware about the Climate change and wants to contribute towards environment protection. A simple technique is to follow four R's which are: Reduce, Reuse, Recycle and Refuse. The four examples given over here are examples of each R as explained below:

Reduce: paying bills online instead of sending paper through the mail as we are reducing the paper use over here.

Reuse: donating gently used clothes and household items so that they can be reused. Using plastic bags a second time to avoid buying new ones.

Recycle & Refuse: buying products that can be recycled so they don’t end up in the trash

A long, nonconducting cylinder (radius = 6.0 mm) has a nonuniform volume charge density given by αr2, where α = 6.2 mC/m5 and r

erastovalidia [21]

Answer: 2.80 N/C

Explanation: In order to calculate the electric firld inside the solid cylinder

non conductor we have to use the Gaussian law,

∫E.ds=Q inside/ε0

E*2πrL=ρ Volume of the Gaussian surface/ε0

E*2πrL= a*r^2 π* r^2* L/ε0

E=a*r^3/(2*ε0)

E=6.2 * (0.002)^3/ (2*8.85*10^-12)= 2.80 N/C

I know the acceleration due to gravity (ie 9.8 m/s2) will have a negative sign when falling down, a positive one when going up.

rewona [7]

Answer:

Yes

Explanation:

Accerelation is measured by change in velocity. So naturally, if an object is slowing down, its velocity is decreasing so acceleration is negative. If it is speeding up velocity is increasing so positive acceleration.

(Velocity final - Velocity initial)/t

Note that this does not apply only to gravity, but to all linear accelerations

Two capacitors, C1 and C2, give an equivalent capacitance of 9.0 pF when connected in parallel and an equivalent capacitance of

Lilit [14]

Answer:

C₁ = 3 pF

C₂ = 6 pF

Explanation:

Let the capacitance be C₁ and C₂.

For parallel combination

C₁ +C₂ = 9

For series combination

$2=\frac{C_1\times C_2}{C_1+C_2}$

$2=\frac{C_1\times C_2}{9}$

C₁ X C₂ = 18

( 9-C₂ )X C₂ = 18

C₂²- 9C₂ +18 = 0

C₂ = 6 or 3.

C₁ = 3 or 6.

C₁ = 3 pF

C₂ = 6 pF
