Answer:
Positive direction
Explanation:
We know that the direction of flow of current is always opposite the direction of the flow of electrons. Assuming that the electrons move in negative direction then the current will flow in the positive direction.
1. The correct answer is B. The nebular theory states that the solar system is the result of the collapse, for unknown reasons, of a large, thin cloud of dust and gas. After this collapse<span>, the pockets of gas and dust started gathering into denser regions. As these regions collected more and more matter, they started to rotate, which led to the accumulation of a big ball in the </span>center<span>, the Sun, and </span>flattenedmatter around, the protoplanetary disc. Then the planets got formed by the accretion of this disc, which eventually created the planets.
2. The correct answer is D. The terrestrial<span> planets were formed by </span>accretion<span> of material that was denser in its constitution. This is the reason why they remained closer to the sun - they were heavier than gas, that is the material the Jovian planets are mostly made of.</span><span />
Mostly because you need to understand the chain of command.
In a centralized organization, the decision making process fall to the hands of a very few people (in some case, it even can fall to one person) , which mean all level of managers can't move freely without the decision maker approval.
In a Decentralized organization, all different managers from different divisions have the authority to make decision
Answer:
Power = 377.35 W or Power = 0.5065 hp
Explanation:
Given:
Number of steps, n = 1576
height of each step, h = 0.20 m
Total height achieved, H = nh = 1576 × 0.20 = 315.2 m
Mass of the runner, M = 70.0 kg
Total time taken, t = 9 minutes 33 seconds = (9 × 60) + 33 = 573 seconds
Now, the potential energy gained by the runner,
E = MgH
where, g is the acceleration due to the gravity
on substituting the values in the above formula, we get
E = 70 × 9.8 × 315.2
or
E = 216227.2 J
also,
Energy = Power × time
therefore,
Power = Energy/time
or
Power = 216227.2 J / 573
or
Power = 377.35 W
Now,
745 watt = 1 hp
or
1 watt = 1/745 hp
thus,
Power = 377.35 W = 337.35 × (1/745) hp
or
Power = 0.5065 hp
Answer:
The magnitude of the force the garbage exerts on the floor of the service elevator is 12 N
Explanation:
Given;
mass of the garbage, m = 10.0 kg
acceleration of the elevator, a = 1.2 m/s²
The magnitude of the force the garbage exerts on the floor of the service elevator is given by;
F = ma
F = 10 x 1.2
F = 12 N
Therefore, the magnitude of the force the garbage exerts on the floor of the service elevator is 12 N
