D.) 5kg
This is a trick question. The mass of an object does not change based in location. However the weight of an object does change, this is because Weight = Mass × Gravity. Also mass is measured in kilograms and so the answer is 5 kg. So if you ever want to lose weight just go to the moon!
Answer:
Material medium
compressions and rarefactions
Explanation:
A sound wave is an example of a mechanical wave. All mechanical waves require a material medium for propagation. The medium for the propagation of sound is air. This is the reason why, if you cover your mouth, it will be difficult for another person to hear whatever you are saying.
Sound is also a longitudinal wave. Longitudinal waves are described in terms of compressions and rarefactions. Compressions refer to areas where air molecules crowd together while rarefactions refer to areas where the air molecules spread out.
Answer:
This is a PERT (Program Evaluation and Review Technique) question and the expected duration of completing this activity can be solved using the formula below.
Pert Expected Duration Estimate = ║Optimistic Duration + (4 x Most Likely Duration) + Pessimistic Duration║/6.
15 days = Most likely Activity Duration.
10 days = Optimistic Activity Duration
20 days = Pessimistic Activity Duration
Substituting these values, we will have
(10 +(4 X 15) +20)/6. The pert estimate is therefore calculated as 15 days
The expected duration of completing this activity = 15 days.
Answer:
9.8 m/s/s, for earth 1.7 N on the Moon.

Answer:
1/2
Explanation:
The energy stored in a capacitor is given by:
where
C is the capacitance
V is the potential difference
For capacitor 1, we have
Capacitor 2 has
(half the capacitance of capacitor 1)
(twice the potential difference of capacitor 1)
So the energy of capacitor 2 is
So, the ratio between the two energies is
