A charge of 4 nc is placed uniformly on a square sheet of nonconducting material of side 17 cm in the yz plane. (a) what is the
Ratling [72]

The charge density of the sheet is 1.384×10⁻⁷C/m².

Charge density is defined as the charge per unit area.

The sheet is a square of length  l=17 cm.

Calculate the area A of the sheet .

A=l^2=(17 cm)^2= (17*10^-^2m)^2=0.0289 m^2

The charge Q on the sheet is

Q=4nC=4*10^-^9C

The charge density σ is given by,

\sigma=\frac{Q}{A}

Substitute 4×10⁻⁹C for Q and 0.0289 m² for A.

\sigma=\frac{Q}{A}\\ =\frac{4*10^-^9C}{0.0289 m^2} \\ =1.389*10^-^7C/m^2

Thus, the charge density of the sheet is <u>1.384×10⁻⁷C/m².</u>

What’s the difference between medium-range training and LSD training? 2. What are the benefits of the starter phase of a fitness
NemiM [27]

1. LSD (or long slow distance) training, also known as a continuous training,  involves performing an activity, such as jogging, cycling or swimming, nonstop for a period of time. This training is targeted for health-related improvements and is often required before engaging to more demanding, aerobic methods like fartlek. Medium-range on the other hand, is where the work period is dominated by the lactic acid energy system. This occurs either when the work period  is between 10 and 60 seconds or when the work-to-rest ratio is 1:2 or 1:3. The aim of medium-interval training is  to develop tolerance of lactic acid.

2. The starter phase allows the body to get used to the idea of exercise, avoid soreness and injury, and to experiment until you find the program that works best for you.
