Which of the following prefixes represents the largest value

A car is traveling at 40 m/s for 20 seconds. How far did it travel in this time?

barxatty [35]

<h3>Answer:</h3>

800 meters

<h3>Explanation;</h3>

<u>We are given;</u>

Speed as 40 m/s
Time as 20 seconds

We are required to determine the distance traveled

Speed refers to the rate of change in distance.
It is given by;

Speed = Distance ÷ time

Rearranging the formula;

Distance = speed × time

In this case;

Distance = 40 m/s × 20 sec

= 800 meters

Thus, the distance traveled by the car is 800 m

s A horizontal insulating rod of length 11.0-cm and charge 19 nC is in a plane with a long straight vertical uniform line charge

guajiro [1.7K]

Answer:

F = 2.26 × 10⁻³ N

Explanation:

given,

length of rod = 11 cm

charge = 19 nC

linear charge density = 3.9 x 10⁻⁷ C/m

electric force at 2 cm away.

$E(r) = \dfrac{2K\lambda}{r}$

F = E q

$F= \dfrac{2K\lambda\ q}{L}\int \dfrac{dr}{r}$

integrating from 0.02 to 0.02 + L

$F= \dfrac{2K\lambda\ q}{L}[ln(0.02+L)-ln(0.002)]$

$F= \dfrac{2\times 9 \times 10^9\times 3.9\times 10^{-7}\times 19 \times 10^{-9}}{0.11}[ln(0.02+0.11)-ln(0.002)]$

F = 2.26 × 10⁻³ N

If a spacecraft in earth orbit is pushed by a thruster what will happen?

grin007 [14]

For the orbital speed of a spacecraft we know that

$v = \sqrt{\frac{GM}{r}}$

here

M = mass of the planet around which satellite is revolving

r = orbital radius

Now when thruster is used by the spacecraft its speed will change due to which orbital speed will change.

Since here while changing the speed mass of the planet will be same

we can say the speed of the spacecraft will changed by thruster due to which its orbital radius will change

so the correct answer must be

<em>b. the spacecraft will change motion and will maintain this new orbit until the thruster is fired again.</em>
