Suppose you walk 18.0 m straight west and then 25.0 m straight north, how far are you from your starting point? answer

Physics
1 answer:
KatRina [158]4 years ago
4 0

Solution:

Since the directions are perpendicular,

So we must use Pythagoras theorem:  

d = √(18.0² + 25.0²) m = 30.8 m

Thus,  

This the required distance from the starting point.

The higher the pressure on a liquid, the higher its boiling point temperature. true false
Alika [10]
True, p1/t1=p2/t2. Pressure is related to temperature at which it boils so pressure does affect the boiling point.

An electron is released from rest at a distance of 0.570 m from a large insulating sheet of charge that has uniform surface char
Lelu [443]

Explanation:

Formula to calculate the electric field of the sheet is as follows.

          E = \frac{\sigma}{2 \epsilon_{o}}

And, expression for magnitude of force exerted on the electron is as follows.

            F = Eq

So, work done by the force on electron is as follows.

           W = Fs

where,     s = distance of electron from its initial position

                  = (0.570 - 0.06) m

                  = 0.51 m

First, we will calculate the electric field as follows.

              E = \frac{\sigma}{2 \epsilon_{o}}

                 = \frac{4.60 \times 10^{-12}C/m^{2}}{2 \times 8.854 \times 10^{-12}C^{2}/N m^{2}}

                 = 0.259 N/C

Now, force will be calculated as follows.

                 F = Eq

                    = 0.259 N/C \times 1.6 \times 10^{-19} C

                    = 0.415 \times 10^{-19} N

Now, work done will be as follows.

                    W = Fs

                        = 0.415 \times 10^{-19} N \times 0.51 m

                        = 2.12 \times 10^{-20} J

Thus, we can conclude that work done on the electron by the electric field of the sheet is 2.12 \times 10^{-20} J.
