Answer:

A girls walks 4 steps forward and then 3 steps backward. The girls distance walked is <u>7</u> steps and her displacement is <u>1 </u>steps.

Explanation:

Distance can be defined as the total length of the path traveled from initial position to final position.

Displacement is the shortest distance between initial position and final position. It is difference between final position and initial position.

When a girl walks 4 steps forward and then 3 steps backwards, the distance traveled is: 4 + 3 = 7 steps

Displacement = 4 (forward)-3 (backwards)  = +1 (forward)

A uniform electric field exists in the region between two oppositely charged plane-parallel plates. An electron is released from
Zigmanuir [339]

Answer:

Explanation:

  • given S = distance from the first = 3.20cm = 0.032m, t = 1.30×10−8 s
  • q = 1.6 x 10_19C
  • using S = at^2/2
  • acceleration = 0.032 X 2 /(1.30×10−8)^2

a = 3.79 x 10^14m/s^2

  • From F = ma
  • F = qE
  • ma = qE

E = ma /q = 9.11 x 10^-31 x 3.79 x 10^14 / 1.6 x 10^-19

E = magnitude of this electric field. = 2156.3N/C

b) Find the speed of the electron when it strikes the second plate ; V^2 = 2as

= 2 X 3.79 x 10^14 X 0.032

= 4.92 X 10^6m/s

How are cactus adapted to survive in deserts?
andreev551 [17]

1. They have evolved their leaves into spikes for minimum water loss through transpiration.

2. They have a waxy layer for minimum water loss.

3. They have thick walls for minimum water loss.

4. They can take water from atmosphere.

5. They change the photo energy from Sun into an intermediate stage and store it, so that they can make food even in night.
