An airplane flew 1000 m in 400 seconds. What is the airplane's speed?

the answer is 2.5 m/s^2

step by step:

1. speed= distance/time

so the speed of the plane = 1000/400

(cancel the two zero's of the 400 with two of the three zero's of the 1000)

you'll have 10/4 left

10/4= 2.5

Answer:

$speed = \frac{distance}{time} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{1000}{400} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2.5m {s}^{ - 1}$

$\dashrightarrow\:\: \sf{ {v}^{2} = {u}^{2} + 2as }$

$\\$

$\dashrightarrow\:\: \sf{ \bigg(\dfrac{v}{2} \bigg)^{2} = {v}^{2} + 2a s_{1}}$

$\\$

$\dashrightarrow\:\: \sf{ \dfrac{ {v}^{2} }{4} = {v}^{2} + 2 \times a \times 0.03 }$

$\\$

$\dashrightarrow\:\: \sf{ \dfrac{ {v}^{2} }{4} - {v}^{2} = 0.06 \times a }$

$\\$

$\dashrightarrow\:\: \sf{\dfrac{ - 3{v}^{2} }{4} = 0.06 \times a }$

$\\$

$\dashrightarrow\:\: \sf{a = \dfrac{ - 3 {v}^{2} }{4 \times 0.06} }$

For which question could a testable hypothesis be developed?

Mandarinka [93]

I believe it’s B; Theories may be proven to be true and become laws.
A would make sense if we were talking about hypotheses however, we’re not.
