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:
In the first range of prices (with PED 15 - 2.5) as the price of the good or service falls, total revenue should increase. Imagine that a 1% reduction in price will result in a 15% increase in quantity demanded. The same happens when PED = 2.5, since a 1% reduction will increase quantity demanded by 2.5%.
e.g. price = $100, quantity demanded = 100, total revenue = $10,000
- price falls to $99, quantity demanded increases to 115, total revenue = $11,385
- price falls to $99, quantity demanded increases to 102.5, total revenue = $10,147.50
On the other range (PED = 1.5 - 0.75) as the price of the good or service falls, at first total revenue will increase but then it will decrease.
e.g. price = $100, quantity demanded = 100, total revenue = $10,000
- price falls to $99, quantity demanded increases to 101.5, total revenue = $10,048.50
- price falls to $99, quantity demanded increases to 100.75, total revenue = $9,974.25
Answer:
A make it a general to include a career goal and qualifying skills
Explanation:
Answer:
False
Explanation:
You can only say an aspect of product performance is mission critical is the sensitivity of the price has been suppressed. Hence the safety of an automobile is a very important factor hence price sensitivity should not increase. In a situation where the product performance is not regarded as mission-critical and if the product fails it is not so significant, then price sensitivity increases.
