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: 17.22%
Explanation:
Effective interest rate is calculated by the formula:
= (1 + APR / Number of compounding periods) ^ Number of compounding periods - 1
Number of compounding periods = 12 months in the year
= (1 + 0.1599/12)¹² - 1
= 0.172155
= 17.22%
Tax helps in stablising the price of product ; because tax is added to the price of product as value added that's why increase in tax system also increases in price of product; also businessmen needs to pay tax from their profit.
Answer:
Explanation:
Credit unions offer higher savings rates and lower interest rates on loans. This means that their members are better served and might be able to save a significant amount on car loans, student loans, and mortgages.
Answer:
option (B) Costs outweigh benefits by $1,600
Explanation:
Given:
Software costs = $10,300
Employee training cost = $8,200
Expected hardware upgrade cost = $12,100
Expected benefits from the inventory tracking system = $29,000
Now,
The total cost of the inventory tracking system
= Software costs + Employee training cost + Expected hardware upgrade cost
= $10,300 + $8,200 + $12,100
= $30,600
Since the cost is more than the benefit, the cost outweigh the benefit
the difference of outweigh = Cost - Benefit = $30,600 - $29,000 = $1,600
Hence,
the correct answer is option (B)
