The answer is D. Mountains in North America appear to be the same as those in Northern Europe
The correct answer is A. Lumen
This is the so called energy of light measurement. Other mentioned measurements are used for different things such as measuring light over an area of space or similar.
Responder:
Velocidad = 41.5m / s
Espacio recorrida = 352.5 metros
Explicación:
Dado lo siguiente:
Velocidad inicial (u) = 19.8 km / h
Aceleración (a) = 2.4m / s ^ 2
Tiempo de viaje (t) = 15 s
A.) velocidad después de 15 s
Velocidad inicial = (19.8 × 1000) m / 3600s Velocidad inicial = 19800m / 3600 = 5.5m / s
Usando la ecuación: v = u + at, donde v es la velocidad
v = 5.5 + 2.4 (15)
v = 5.5 + 36
v = 41.5m / s
Espacio recorrida:
v ^ 2 = u ^ 2 + 2aS; donde S es la distancia recorrida
41.5 ^ 2 = 5.5 ^ 2 + 2 × (2.4) × S
1722.25 = 30.25 + 4.8S
1722.25 - 30.25 = 4.8S
1692 = 4.8S S = 1692 / 4.8 S = 352.5m
Can you write out the question please? :) Sorry, i don't see it on the paper
Answer:
Average
= 11.25 cm
standard deviation = 0.129 cm
Explanation:
The data provided in the question is:
x₁ = 11.4 cm
x₂ = 11.3 cm
x₃ = 11.2 cm
x₄ = 11.1 cm
total number of data points, N = 4
Now, the average is calculated as:
Average
= 
substituting the values in the above formula we get,
Average
= 
Average
= 11.25 cm
Now the standard deviation is calculated as:
standard deviation = 
substituting the values in the above equation we get,
standard deviation = 
or
standard deviation = 0.129 cm
