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

Answer:

Equilibrium is reached when demand equals supply.

Explanation:

Demand is the amount that consumers want and can buy of a certain product or service in a specific period of time and at a certain price. On the other hand, the supply is the amount that producers want and can sell of a certain product or service in a specific period of time and at a certain price.

In market equilibrium, the quantity demanded of the product or service equals the quantity supplied, so the price also equals. In other words, when market equilibrium is reached, demand and supply are the same, with their corresponding equilibrium price and quantity.

Two situations can occur:

  • When the quantity demanded is greater than the quantity supplied, the market is in a situation of excess demand.
  • On the other hand, it may happen that the price at which the products are being offered is greater than the equilibrium price and the quantity supplied is greater than the quantity demanded. Then there is an excess supply.

<u><em> Equilibrium is reached when demand equals supply.</em></u>

A rock is stuck deep in the dirt. When you pull on the rock to remove it, what type of force are you exerting?
aleksandrvk [35]
It is Tension as the other 3 answer choices would not make sense. Compression would mean you are pressing the rock on both sides or in this case, pushing it into the dirt. It can't be nuclear force as you are pulling out a rock. Air resistance would not make sense either as there is no air involved in the scenario at all.

2. You and a friend are spending a weekend at a carnival. You get bored and begin to make electrostatics measurements. It turns
aleksklad [387]

Answer:

B) -2 Coulombs

Explanation:

In order to find the net charge, we must add the charge that you have with the charge that your friend has, but taking into account the different sign. In fact, we have:

- Charge possessed by you: Q1 = +3 C

- Charge possessed by your friend: Q2 = -5 C

Therefore, the net charge possessed by both persons will be given by

Q = Q1 + Q2 = +3 C + (-5 C) = +3 C - 5 C = -2 C
