We do not feel the gravitational forces from objects other than the Earth because they are weak.
Well since I don't have access to a high vacuum pump or good glassblowing equipment I would say wiring would be cotton thread and the coating would be carbon, ideally with a high vaccum pump and glassblowing equipment I'd say platinum wire with a resistive coating to prevent the platinum from getting to hot but would keep it incandescent for a very long time.
Answer:
The correct option is b: 30 N.
Explanation:
First, we need to find the acceleration due to gravity (a):
(1)
Where:
: is the final vertical position (obtained from the graph)
: is the initial vertical position (obtained from the graph)
v₀: is the initial speed = 0 (it is released from rest)
Δt: is the variation of time (from the graph)
From the graph, we can take the following values of height and time:
t₀ = 0 s → = 5 s
y₀ = 300 m → = 225 m
Now, by entering the above values into equation (1) and solving for "a" we have:
Finally, the weight of the object is:
Therefore, the correct option is b: 30 N.
I hope it helps you!
Answer:
Slit separation,
Explanation:
It is given that,
Wavelength of light,
The angle between the central bright fringe and the second dark fringe,
In case of double slits, the condition for dark fringe is given by :
n = 2
So, the slit separation is . Hence, this is the required solution.
The box of 15 baseballs because it has more weight.
