Choice-'a' is a slippery, misleading, ambiguous statement,
but it's less wrong than any of the other choices on this list.
Answer:
The telescope can gather light 1600 times more than the human eyes can!
Explanation:
The light gathering ability of an optical element is directly proportional to its area of opening.
So, in comparing the light gathering abilities for two objects, it is just the ratio of their area of opening.
Let the diameter of the telescope be D = 1 m
And the diameter of the human eyes be d = 2.5 cm = 0.025 m
Light gathering ability of the telescope compared to the eyes = D² ÷ d²
= (D²/d²) = (1²/0.025²) = 1600 times.
The telescope can gather light 1600 times more than the human eyes can!
Hope this Helps!!!
Answer:
Our modern ideas about government were influenced by many different ideas and traditions. The biggest influence came from their British heritage. (Remember the colonists WERE British until the American Revolution!)
Answer:
B
Explanation:
The mass of something before it's been processed is the same as it's mass after the process.
Here the weight is hung from the thread inside the ceiling of train
now the FBD of train is analysed
We can say
now by ratio of two equations we have
this shows that train must be in accelerating condition due to which the thread is making an angle with the vertical
now we will have
2 The train is not an inertial frame of reference.
Since train is accelerating so it must be non inertial frame
5 The train may be moving at a constant speed in a circle.
Since its moving in circle so it is in accelerating condition
8 The train must be accelerating.
