Answer:

The three remaining light bulbs will remain dark.

Explanation:

Current can only flow if there is a complete circuit through all of the series elements. With one element removed, no current can flow, so the remaining light bulbs cannot light up.

A physicist found that a force of 0.72N was measured between two charged sphere. The distance between the sphere was 0.90 m. Cal
aalyn [17]
What you can use is coulomb's inverse square law that states that force varies inversly as the square of distance.  <span>It menas that the force is calculated by dividing by distance squared. what this does is essentially as the distance doubles, the forces is reduced by a factor of 4 or can be divided by 4. Force at 0.5m=2.3328N. And brings you ti the answer</span>

found the potential spring energy. not sure how to find the height of the block by knowing only the mass. found the weight of it
evablogger [386]

(h + .16) m g = 1/2 k x^2   total PE of block relative to where it stops

(h + .16) .82 * 9.8 = .5 * 120 * .16^2    PE released = PE of  spring

8.04 h + 1.29 = 1.536

h = (1.536 - 1.29) / 8.04 = .031 m = 3.1 cm

It is dangerous to stand near the railway leak when train passing by,why?​
Harman [31]

It is dangerous to stand close to railroad tracks when a rapidly moving commuter train passes. Explain why atmospheric pressure would push you toward the moving train. Water pressure inside a hose nozzle can be less than atmospheric pressure due to the Bernoulli effect.

Pls brainliest!? :)
