A cheetah can run at a maximum speed

vivado [14]

Answer:

25 seconds (rounded up to nearest one second)

Explanation:

Cheetah's speed = 91.8 km/h

Gazelle's speed = 77.9 km/h

Both animals are running at full speed with the gazelle 97.3 m ahead.

Converting their respective speeds to m/s ;

Cheetah's speed = $\frac{91.8 * 1000}{3600}$ = 25.5 m/s

Gazelle's speed = $\frac{77.9 * 1000}{3600}$ = 21.6 m/s (correct to one decimal place)

Assuming the gazelle stops, cheetah will run at 25.5 m/s - 21.6 m/s = 3.9 m/s to catch its prey (gazelle).

Time = distance ÷ speed

The time cheetah will take to catch its prey = 97.3 m ÷ 3.9 m/s = 24.94871795 s = 25 seconds (rounded up to nearest one second)

Se ha medido la altura de varios a alumnos y se han obtenido las siguientes medidas: 1.63 m, 1.54 m, 1.67 m, 1.59 m. a. Halla el

JulsSmile [24]

Answer:

Explanation:

Se ha medido la altura de varios alumnos y se han obtenido las siguientes medidas: 1.63 m, 1.54 m, 1.67 m, 1.59 m

a) Encuentra el error absoluto de cada medición.

Primero encontramos la media de las Medidas

(1.63 + 1.54 + 1.67 + 1.59) m / 4

= 1.6075m

Aproximadamente = 1,61 m

Por lo tanto, el error absoluto para cada medición es:

i) 1.63 m

| 1.63 - 1.61 | = | 0.02 | = 0.02

ii) 1.54 m

| 1.54 - 1.61 | = | -0.07 | = 0.07

iii) 1.67 m

| 1.67 - 1.61 | = | 0.06 | = 0.06

iv) 1,59 m

| 1.59 - 1.61 | = | -0.02 | = 0.02

segundo.

b. Encuentra el error relativo de cada medida.

El error relativo se calcula como:

Fórmula de error relativo = Error absoluto / valor verdadero

i) 1.63 m

| 1.63 - 1.61 | /1.61 = | 0.02 | / 1.61 = 0.02 / 1.61

= 0.0124

ii) 1.54 m

| 1.54 - 1.61 | / 1.61 = | -0.07 | /1.61 = 0.07 / 1.61

= 0.0435

iii) 1.67 m

| 1.67 - 1.61 | /1.61 = | 0.06 | /1.61 = 0.06 / 1.61

= 0.0373

iv) 1.59 m

| 1.59 - 1.61 | /1.61 = | -0.02 | /1.61 = 0.02 / 1.61

= 0.0124
