When four identical light bulbs are connected in parallel and this combination is connected to an ideal battery, the bulbs each glow with a certain brightness until the battery runs down after six hours. [Recall that an ideal battery is one with no internal resistance.] If two of the light bulbs are removed so that there are just two light bulbs in parallel and then this combination is connected to a new (but otherwise identical) battery, Question 6 options:

the remaining two bulbs will each glow with the same brightness as each bulb did before and the battery will last for six hours.

the remaining two bulbs will each glow more brightly than each bulb did before and the battery will still last for six hours.

the remaining two bulbs will each glow more dimly than each bulb did before and the battery will last for twelve hours.

the remaining two bulbs will each glow with the same brightness as each bulb did before and the battery will last for twelve hours.

the remaining two bulbs will each glow more dimly than each bulb did before and the battery will last for 24 hours.

the remaining two bulbs will each glow more brightly than each bulb did before and the battery will last for three hours.

Can someone please provide a feedback on the discussion post below. Thank you. It is a marketing management class.

Amazon.com is one of the fastest growing companies to date. Amazon utilizes Facebook, Twitter, YouTube, and a company blog in order to reach out to their consumers. What I have noticed on their YouTube channel is that they have a variety of different kinds of videos that all relate to the average consumer. In addition, Amazon is able to use celebrity guests, as well as "average-Joe-looking" actors who are relatable to the public. They utilize tutorial videos to help users with trouble-shooting, as well as displaying newly released products to the market. Recently on Amazon's Facebook page and Twitter account, they have introduced a video that outlines tips for entrepreneurs. It seems entrepreneurship is a common theme displayed on Amazon's Facebook and Twitter. Perhaps this is a way for them to spark new ideas from their consumers that they can then create into reality in the future. In addition, Amazon's blog page has links such as: Supporting small businesses, job creation and innovation. After looking through Amazon's social medial outlets over the past four days it seems that Amazon makes it a priority to invest in their consumers/employees by giving them opportunities to develop their creativity.

Company A purchases Company B. This is a 100% equity purchase which means that Company A acquires all of the Company B assets and assumes the liabilities of Company B.

Calculate the value of goodwill recognized in the acquisition. Round to the nearest whole dollar and do not include the dollar sign ($).

Assume

  • the current market value of tangible physical assets is $1,357,924 (determined by Company A as at the acquisition date)
  • the current market value of the only identifiable intangible asset (a customer list) is $125,000 (determined by Company A as at the acquisition date)
  • Operating (non-Financial) liabilities have an appraised value of $300,000 before and after the acquisition.
  • Financial Liabilities were appraised by company B to be valued at $600,000 immediately Before the acquisition.
  • Financial Liabilities were appraised by Company A to be valued at $495,000 immediately After the acquisition.
  • There are no other assets or liabilities to consider than those presented above
  • Company A paid $987,000 cash for Company B.

A mid-distance running coach claims that his six-month training program significantly reduces the average time to complete a 1500-meter run. Five mid-distance runners were randomly selected before they were trained with the coach’s six-month training program and their completion time of 1500-meter run was recorded (in minutes). After six-months of training under the coach, the same five runner’s 1500 meter run time recorded again, the results are given below. Runner 1 2 3 4 5 Completion time before training 5.9 7.5 6.1 6.8 8.1 Completion time after training 5.4 7.1 6.2 6.5 7.8 18. Is the statement that the training program reduce the mean run time at 5% level of significance. (Hint: paired samples) 19. What conclusion you can draw about the claim of the coach?

A 0.00410–kg bullet traveling horizontally with a speed of 1.00 ✕ 103 m/s enters a 21.0–kg door, embedding itself 19.0 cm from the side opposite the hinges as in the figure below. The 1.00–m–wide door is free to swing on its hinges.

(a) Before it hits the door, does the bullet have angular momentum relative to the door's axis of rotation?

Yes or No     


Explain.



(b) Is mechanical energy conserved in this collision? Answer without doing a calculation.

Yes or No     


(c) At what angular speed does the door swing open immediately after the collision? (The door has the same moment of inertia as a rod with axis at one end.)
rad/s

(d) Calculate the energy of the door–bullet system. (Enter the kinetic energy of the door–bullet system just after collision.)
J

Determine whether the energy of the door–bullet system is less than or equal to the kinetic energy of the bullet before the collision.

less than or equal

Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 4.7 m/s2 for 3.8 seconds. It then continues at a constant speed for 8.4 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 205 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the blue car comes to a stop.

How fast is the blue car going 2.7 seconds after it starts?

How fast is the blue car going 9.6 seconds after it starts?

How far does the blue car travel before its brakes are applied to slow down?

What is the acceleration of the blue car once the brakes are applied?

What is the total time the blue car is moving?

What is the acceleration of the yellow car?

1) What is the shortest possible length of an mRNA molecule that corresponds to a polypeptide 10 amino acids long? For your answer just give me the number. E.g., "12" or "120." (Ignore the 5' cap and poly-A tail.)

2) How can the deletion of one nucleotide result in a longer polypeptide being made? Write out 2 examples of mRNA sequence (before and after the mutation) and its corresponding amino acid sequence (before and after the mutation) to show how this could happen.

3)In the metabolic pathway above, paraoxon is the most toxic compound. What change would likely lead to the greatest build-up of paraoxon in the body?

Group of answer choices

a) decrease in the amount of diethylphosphate and p-nitrophenol in the body.

b) nonsense mutation near the beginning of the gene that codes for cytochrome P450.

c) silent mutation in the gene that codes for paraoxonase.  

d) severe change in the shape of the active site of paraoxonase.
