<u><em>Answer:</em></u>
Destructive interference
<u><em>Explanation:</em></u>
<u>Interference</u> is a term used to refer to the combination of two waves or their overlap
<u>There are two types of interference:</u>
<u>1- Constructive interference:</u> This happens when the waves overlap/combine to produce a resultant wave with a larger displacement
<u>2- Destructive interference:</u> This happens when the waves overlap/combine to produce a resultant wave with a smaller displacement
Hope this helps :)
The box moved 0.73 m
<u>Explanation:</u>
Given data,
Magnitude 8.1 N Work on the box 5.9 J Clerk move a 4.4 Kg
Distance= work done on the box / Horizontal force on the magnitude
= 5.9/8.1
=0.728
Distance =0.73 m
The box moved 0.73 m
I dont know but i think is A
i think that dont help but if is not that one tell me and im going to try again
That distance is the definition of 1 AU.
Answer:
2.7 Pizzas.
Explanation:
The power required to walk through 5km in 1 hour is 380W.
A watt is basically Jules per second, then we need to standardized this measurement to second.
5km/hr is equal to,
![\frac{5km}{hr}*\frac{1hr}{3600s}*\frac{1000m}{1km}=1.389m/s](https://tex.z-dn.net/?f=%5Cfrac%7B5km%7D%7Bhr%7D%2A%5Cfrac%7B1hr%7D%7B3600s%7D%2A%5Cfrac%7B1000m%7D%7B1km%7D%3D1.389m%2Fs)
Walking by 2.5 hours is equal to a distance of,
![d=v*t=1.389*(2.5*3600) = 12500m](https://tex.z-dn.net/?f=d%3Dv%2At%3D1.389%2A%282.5%2A3600%29%20%3D%2012500m)
The total energy required then would be,
![E = \frac{380J}{1.389m/s}(12500)=3.4199*10^6J](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7B380J%7D%7B1.389m%2Fs%7D%2812500%29%3D3.4199%2A10%5E6J)
Then we know that one pizza slice gives
of energy, the total pizza needed are,
![\eta = \frac{3.4199*10^6}{1260*10^3} = 2.7142](https://tex.z-dn.net/?f=%5Ceta%20%3D%20%5Cfrac%7B3.4199%2A10%5E6%7D%7B1260%2A10%5E3%7D%20%3D%202.7142)
<em>Then you need to buy 3 pizza.</em>
