7. You start to walk toward the east towards home at a constant speed of 4 km/hr. At the same time, Someone else leaves your hom
amm1812

A) position time graph for both is shown

here one of the graph is of lesser slope which means it is moving with less speed while other have larger slope which shows larger speed

At one point they intersects which is the point where they both will meet

B) Let the two will meet after time "t"

now we can say that

if they both will meet after time "t"

then the total distance moved by you and other person will be same as the distance between you and home

so it is given as

v_1t + v_2t = d

4*t + 28*t = 3.2 km

t = \frac{3.2}{32} = 0.1 hr

so they will meet after t = 6 min

so from position time graph we can see that two will meet after t = 6 min where at this position two graphs will intersect

a person takes a trip, driving with a constant speed of 89.5 km/h except for a 22.0 min rest stop. if the person’s average speed
fredd [130]

TheThe  distance they have covered for trip is 219Km.



<h3>What do you mean by uniformly accelereted motion?</h3>

When an object is traveling in a straight line with an increase in velocity at equal intervals of time.

The total time for the trip is

T→  t1+ 22 min = t1+ 0.367 h ,where t1 is the time spent traveling at

V1= 89.5 km/ h .

the distance traveled is ∆x = V1t1=Vavg T

after applying value and calculating it we get

 t1= 2.44h for a total time of

t total we get 2.81 h .

∆x =V1T1 = VavgTtotal

 ∆x = 77×2.81= 219 Km

1. Why is the theory that all things are made up of atoms a theory and not a fact?
steposvetlana [31]
Because there is no record of all things. As we have partially unknow information, it can never be held as a fact.

Elis [28]

Answer:

(D) any of these objects can be used as long as all points on the object lie farther away from the lens than the focal length of the lens.

Points lying between the focal point and the lens will be erect and will not form an object visible on a screen.
