Answer:

When the air filled balloon is left with its mouth downwards and allowed air to escape which is an action, the air exerts the upward force on the balloon which is a reaction. So, due to the reaction force balloon moves in the upward direction.

Explanation:

hope it helps

good day

thank u ✌️

A large goose lands in a lake and bobs up and down for a short time. A fisherman notices that the first wave crest created by th
sleet_krkn [62]

Answer:

11.85m

Explanation:

For the development of this problem we must resort to the concepts of the basic kinematic equations that define the distance of a body, such as speed for a certain time, that is,

D=v*t

From the information provided we say that the distance between the cretas is 0.6m,

D_{crest} = 0.6m

In our information we have also that the length between the first and latest wave is in time terms of 2.2s. They are 4 waves in 3 intervals then

D_{T} = D_{crest}*3= 0.6*4 = 2.4m

t=1.6s

\upsilon = \frac{D_{T}}{t} = \frac{2.4}{1.6}

\upsilon = 1.5 m/s

Then the distance from the shore is given by the speed of the waves for the total time. That is

X = \upsilon*T\’

X = 1.5*7.9

X= 11.85m

What is the correct answer?
pentagon [3]

Answer:

B) x^2+6x+8

Explanation:

x-4 | x^3+2x^2-16x-32

    -  x^3-4x^2             <-- (x-4)(x^2)

_________________

              6x^2-16x-32

           -  6x^2-24x     <-- (x-4)(6x)

_________________

                          8x-32

                       -  8x-32 <- (x-4)(8)

___________________________

                                 0 | x^2+6x+8

This means the answer is B) x^2+6x+8

A truck is moving around a circular curve at a uniform velocity of 13 m/s. If the centripetal force on the truck is 3,300 N and
sashaice [31]
The radius of the curve is 81.93 metres. We can work this out by considering the centripetal force (Fc) = mass x centripetal acceleration.
Fc = m x u (squared)
R = mu (squared) over Fc = 1600 x (13 squared) over 3300
R = 81.93 metres
