A total solar eclipse is visible froma. all over Earth.
b. only within the moon’s umbra.
c. only within the moon’s penumbra.
d. only the dark side of Earth.

Answers

Answer 1
Answer:

Answer:

b. only within the moon’s umbra.

Explanation:

Solar eclipse occurs when Moon comes between the Sun and the Earth in straight line and blocks the sunlight. A shadow of moon castes on the surface of the Earth. The region passing through the moon's umbra would view a total solar eclipse. The moon completely hides the surface of the sun. It would be visible to the people residing in the bright side of the Earth within the Umbra of the moon.
Answer 2
Answer: Only within the umbra of the moon's shadow.

1. A rifle with a longer barrel can fire bullets with a larger velocity than a rifle with a shorter barrel.

Answers

i dont believe so because thw longer the barrel the longer the bullet is inthe rifle shortening the force from the friction with the barrel so a rifle with a shorter barrel would be betterto use than one with a lomger barrel even though the longer barreled rifle may be more presice

suppose that i suspect that running my ceiling fan stirs up dust and causes my table to become dusty. how could i use the method of concomitant variations to confirm this?

Answers

The use the method of concomitant variations we need to identify the variables, establish a baseline, introduce variation and compare results.

To use the method of concomitant variations to confirm whether running your ceiling fan stirs up dust and causes your table to become dusty, follow these steps:

1. Identify the variables: In this case, the independent variable is the operation of the ceiling fan (on or off), and the dependent variable is the dust accumulation on your table.

2. Establish a baseline: Observe the dust accumulation on your table when the ceiling fan is off for a specific period, let's say 24 hours. Document the amount of dust on the table.

3. Introduce variation: Turn on the ceiling fan and observe the dust accumulation on your table for the same period (24 hours). Document the amount of dust on the table.

4. Compare results: Compare the dust levels on your table when the ceiling fan was off versus when it was on. If there is a concomitant (simultaneous) increase in dust accumulation when the fan is on, this suggests a relationship between the operation of the ceiling fan and the dust on your table.

5. Repeat the process: To strengthen your evidence, perform the same experiment multiple times, alternating between turning the fan on and off. If the pattern of increased dust accumulation consistently occurs when the fan is on, this further supports the hypothesis that the ceiling fan stirs up dust and causes your table to become dusty.

What does the equation n =Pout/Pin mean?

Answers

Answer:

Power efficiency

Explanation:

The power efficiency tells us how much efficient is a process, the bigger value we can obtain is 1, that means that we are not wasting energy, in real life, it is always below 1 because some energy is wasted on heat or other undesired process. that's why the output power is always lower than the input power.
n= energy efficiency pout means output and pin means input the reason this would show efficiency is because your output should be greater then your input and because depending on how small your number is after your division will tell you how efficient it is you want a big number.
