A flying squid (family Ommastrephidae) is able to "jump" off the surface of the sea by taking water into its body cavity and the

n ejecting the water vertically downward. A 0.70 kg squid is able to eject 0.26 kg of water with a speed of 20 m/s.(a) What will be the speed of the squid immediately after ejecting the water? (b) How high in the air will the squid rise?

Answer: V=7.43m/s

d =2.82m

Explanation:

a) For the first part, the initial velocity immediately after ejection, by using momentum conservation

before ejection, the momentum of the squid/water system is zero

there are no external forces acting on the system at the moment of ejection, so we can find the speed of the squid by noting

momentum before ejection = momentum after ejection

0 = M1U + M2V

0=-0.26 kg x 20 m/s + 0.7kg x V

where the speed of the water is taken as the negative sign, and V is the speed of the squid right after ejection, solving for V we get

V=7.43m/s

B. we use the equation vf^²=v0^²+2ad

where vf=final velocity = 0 since velocity is zero at motion's apex

v0=initial velocity = 7.43m/s

a = acceleration = -9.8m/s/s

d=height (to be found)

Therefore,

0=7.43^²+2(-9.8)d

Mathematically, it becomes

d=7.43^²/2(9.8)= 2.82m

d = 2.82m

Answer:

periodically pay a fixed rate of interest and receive a floating rate of interest.

Explanation:

The interest rate (rate of return) can be defined as the percentage of interest or dividends earned on money that is invested.

In Financial accounting, a return refers to the amount of profit generated by an investor on an investment over a specific period of time.

Basically, the interest rate which is typically expressed as a percentage of the initial costs of an investment can either be a gain or a loss on an investment. Therefore, a positive rate of return on an investment over a specific period of time, simply means that an investor is making a profit (gains) while a negative rate of return on an investment over a specific period of time, indicates that the investor is running at a loss.

By convention, a swap buyer on an interest rate swap agrees to periodically pay a fixed rate of interest and receive a floating rate of interest.

A firm's attempts to shorten the length of time a process takes, may lead to disappointing outcomes because of ______.
liraira [26]

A firm's attempts to shorten the length of time a process takes may lead to disappointing outcomes because of time compression diseconomies.

<h3>What are time compression diseconomies?</h3>
  • According to time compression diseconomies, which are defined as inefficiencies that arise when work is done more quickly, the cost of building a competency will rise exponentially as the amount of time permitted to do so decreases.
  • Not every subsidiary deals with time compression diseconomies to the same extent.
  • The date of a later subsidiary formation may affect how strong TCD is. Early-established subsidiaries may have greater TCD than later entries due to two factors.
  • First, for late movers, vicarious learning may lower TCD. Second, TCD is made worse by the higher environmental uncertainty that early mover subsidiaries frequently experience.
  • TCD explains why the well-studied relationship between the level of multi-nationality and business success is negatively moderated by the rate of overseas expansion.
