David is running laps around his apartment complex. Each lap is 1000 m. Starting from his front door and ending at his front doo

adelina 88 [10]

Answer:

Displacement = 4000 m

Explanation:

Given that,

Each lap is 1000 m.

David completes 4 laps of his complex

We need to find David's displacement. In n laps, the net displacement is n time of distance covered.

Displacement = 4 × 1000

= 4000 m

Hence, Davis's displacement is 4000 m.

How do you inhibitors work

bonufazy [111]

Answer:

By binding to enzymes' active sites, inhibitors reduce the compatibility of substrate and enzyme and this leads to the inhibition of Enzyme-Substrate complexes' formation, preventing the catalyzation of reactions and decreasing (at times to zero) the amount of product produced by a reaction.

Find the force in free space between two like point charges of one coulomb each placed one metre apart

Umnica [9.8K]

Explanation:

${ \rm{force = \frac{q _{1}q _{2} }{4\pi \phi \: {r}^{2} } }} \\$

q is charge
4πQ is 1 / (9 × 10^9)
r is separation distance

${ \rm{force = \frac{1 \times 1 \times 9 \times {10}^{9} }{ {1}^{2} } }} \\ \\ { \boxed{ \rm{force = 9 \times {10}^{9} \: newtons }}}$

A sock stuck to the inside of the clothes dryer spins around the drum once every 2.0 s at a distance of 0.50 m from the center o

Rashid [163]

a) 1.57 m/s

The sock spins once every 2.0 seconds, so its period is

T = 2.0 s

Therefore, the angular velocity of the sock is

$\omega=\frac{2\pi}{T}=\frac{2\pi}{2.0}=3.14 rad/s$

The linear speed of the sock is given by

$v=\omega r$

where

$\omega$ is the angular velocity

r = 0.50 m is the radius of the circular path of the sock

Substituting, we find:

$v=(3.14)(0.50)=1.57 m/s$

B) Faster

In this case, the drum is twice as wide, so the new radius of the circular path of the sock is twice the previous one:

$r' = 2r = 1.00 m$

At the same time, the drum spins at the same frequency as before, therefore the angular frequency as not changed:

$\omega' = \omega = 3.14 rad/s$

Therefore, the new linear speed would be:

$v'=\omega' r' = \omega (2r)$

And substituting,

$v'=(3.14)(1.00)=3.14 rad/s = 2v$

So, we see that the linear speed has doubled.
