It makes no difference whether there are two bulbs or 1000 bulbs. If they are all in series then when one bulb burns out, or one little piece of wire between two bulbs comes loose, ALL of them go dark. In that situation it's a challenge to find where the break in the circuit is because all of the bulbs are dark.
Answer:
The unit is usually seconds. But it really depends on the situation you are in. If you are talking about uranium-238, then you'll be talking about a half life in the billions of years. However, if you are talking about the half-life of a muon, then it'll be in seconds or microseconds.
Answer:
the required minimum magnitude of the force F is 21 N
Explanation:
Given the data in the question,
m = 5 kg
width = 60 cm
height = 80 cm
Let force is F represent in the image below,
so when the block about to rotate normal shifted to edge of cube
mg(w/2) = Fh
F = mg(w/2) / h
we know that g = 9.8 m/s²
we substitute
F = (5 × 9.8 ( 60/2)) / 70
F = (5 × 9.8 × 30 ) / 70
F = 1470 / 70
F = 21 N
Therefore, the required minimum magnitude of the force F is 21 N
Answer:
The new planet has more gravity
Explanation:
gravity force = G m1 m2 / r^2
decresing r or increasing the planet mass will increase the force
