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:
B. save your document frequently
Explanation:
Saving your documents time to time will prevent loss of work on computer which could be possible due to different reasons like electricity off, some wiring issue or even hardware/software of computer could be hanged.
So saving frequently can save your work also it is best practice to save in different name so that older history is maintained.
New solution to these problems are using cloud based documents those auto save your work and also maintain history.
Answer: $175
Explanation:
Here we can see that the business discussion happened only at dinner.
After Dinner they went for entertainment at the Cinema so that amount is not deductible as a business Expense.
The only amount deductible is the $350 for the meal.
Meals with clients are considered to be 50% deductible so solving for that we have,
= 350 * 0.5
= $175
$175 is amount of the expenditures that Holly can deduct as a business expense.
I believe the answer is: by purchasing shares of the company
By purchasing a certain amount of shares, that investor automatically became part-owner of the company. For majority of companies, every 4 months, the company would announce the amount of dividend that they will give to the share owners. The amount of dividend that the owners receive would be according to the percentage of shares that they own.
