Are we talking about extinct?

I think it could be possible. However, the creature may not last long. Creatures from the distant past died off for a reason, they couldn't survive. So, with the sudden change in environment, they won't last long, especially if they didn't last in the past.

Al considerar 51 m la distancia entre dos puntos situados realmente a 52.06 m cual es el error absoluto y relativo.

Tamiku [17]

Answer:

Absolute error = 1.06 m

Relative error = 0.02

Explanation:

When considering 51 m the distance between two points actually located at 52.06 m which is the absolute and relative error.

Given that the actual distance between the two points is 52.06 m

Considered distance = 51 m

Error = Actual value - Measured value

=52.06m - 51m

=1.06m

The value is already positive, so the absolute error is also 1.06m.

Relative error =( error)/(actual value)

=1.06/52.06=0.02

Hence the relative error is 0.02.

The free-fall acceleration on Mars is 3.7 m/s2.

hichkok12 [17]

Answer:

(a) The length of the pendulum on Earth is 36.8cm

(b) The length of the pendulum on Mars is 13.5cm

(d) Mass suspended from the spring on Mars is 0.36kg

Explanation:

Period = 1.2s, free fall acceleration on Earth = 9.8m/s^2, free fall acceleration on Mars = 3.7m/s^2

( a) Length of pendulum on Earth = [( period ÷ 2π)^2] × acceleration = (1.2 ÷ 2×3.142)^2 × 9.8 = 0.0365×9.8 = 0.358m = 35.8cm

(b) Length of the pendulum on Mars = (1.2÷2×3.142)^2 × 3.7 = 0.0365×3.7 = 0.135cm = 13.5m

(c) Mass suspended from the spring on Earth = (force constant×length in meter) ÷ acceleration = (10×0.358) ÷ 9.8 = 0.37kg

(d) Mass suspended from the spring on Mars = (10×0.135)÷3.7 = 0.36kg

Elle is playing with a ball in a bus that moves in a straight line with constant velocity. What can you say about the motion of

kramer

Given that they are all on the same bus that is travelling in a straight line at the same velocity, when Elle throws the ball directly upwards, the ball will simply fall back to her. This is because the bus, Elle, and the ball are all travelling in the same direction and at the same speed. Among the choices, the correct answer is A.
