nciado: Frequentemente, em ciências exatas, utilizamos potências de base 10 para expressar números muito grandes ou muito pequen

os. Para as potências de base 10 mais utilizadas foram desenvolvidos os prefixos e símbolos. Por exemplo, o prefixo centi (simbolizado pela letra minúscula c) se refere à potência 10-2. Então, se fizermos uma medida de 0,01 metro, ela poderá ser escrita como 1.10-2m ou, então, como 1 cm (um centímetro). Existem vários outros prefixos, é importante saber usá-los corretamente e adotar a simbologia adequada. Dentre as opções abaixo, qual seria a opção correta para escrevermos a medida de 30 000 gramas (g) em potência de base 10? Escolha uma:

If a body travels half its total path in the last 1.50 s of its fall from rest, find the total time of its fall (in seconds).
svetoff [14.1K]

Answer:

time to fall is 3.914 seconds

Explanation:

given data

half distance time = 1.50 s

to find out

find the total time of its fall

solution

we consider here s is total distance

so equation of motion for distance

s = ut + 0.5 × at²   .........1

here s is distance and u is initial speed that is 0 and a is acceleration due to gravity = 9.8 and t is time

so for last 1.5 sec distance is 0.5 of its distance so equation will be

0.5 s = 0 + 0.5 × (9.8) × ( t - 1.5)²     ........................1

and

velocity will be

v = u + at

so velocity v = 0+ 9.8(t-1.5)    ..................2

so first we find time

0.5 × (9.8) × ( t - 1.5)² = 9.8(t-1.5)  + 0.5 ( 9.8)

solve and we get t

t = 3.37 s

so time to fall is 3.914 seconds

What materials in a torch are conductors and insulators?
Alisiya [41]
Are you sure you weren't given any options? Basically the electrical components, e.g wires and bulbs will be conductors, and the part comprising the outer casing, e.g plastic, glass, will be insulators
