Respuesta:

a) 12.3 m/s²

b) 153.75 m

c) 36.9 m/s

Explicación:

Paso 1: Información provista

  • Fuerza aplicada (F): 8 N
  • Masa del cochecito (m): 650 g

Paso 2: Calcular la aceleración (a) del cochecito

Usaremos la segunda ley del movimiento de Newton.

F = m × a

a = F/m = 8 N / 0.650 kg = 12.3 m/s²

Paso 3: Calcular el espacio recorrido (x) en 5 segundos (t).

Usaremos la siguiente fórmula cinemática para un movimiento rectilineo uniformemente acelerado.

x = 1/2 × a × t²

x = 1/2 × 12.3 m/s² × (5s)² = 153.75 m

Paso 4: Calcular la velocidad (v) a los 3 segundos si parte del reposo

Usaremos la siguiente fórmula cinemática para un movimiento rectilineo uniformemente acelerado.

v = a × t

v = 12.3 m/s² × 3 s = 36.9 m/s

What is the average value expected for the independent-measures t statistic if the null hypothesis is true?
Bogdan [553]

The average value for t- statistics is 0 if null hypothesis is true.

What is a t – statistics and null hypothesis ?

  • The t-statistic, which is used in statistics, measures how far a parameter's estimated value deviates from its hypothesized value relative to its standard error.
  • Through the Student's t-test, it is utilized in hypothesis testing. In a t-test, the t-statistic is used to decide whether to accept or reject the null hypothesis.
  • It is quite comparable to the z-score, but when the data is small or the standard deviation is unknown, the t-statistic is employed instead.
  • The default assumption, or null hypothesis, is that the quantity being measured is zero (null). The quantity to be assessed is often the difference between two circumstances.
  • Trying to determine, for instance, whether there is conclusive evidence that an impact has happened or that samples come from several batches

The t-test yields a t-value of 0 if the sample data precisely match the null hypothesis. The value of the t-value rises as the sample data diverge more and more from the null hypothesis.

Identify the relationship between kinetic energy and gravitational potential energy for the cyclist at each position
sasho [114]

Answer:

follows are the responses to the given question:

Explanation:

The kinetic energy of every object moving.  PK=m \times v^2 any entity lifted against the strength of gravity stores elastic potential of gravity.

PE = height \times mass  \times  g

Its total power of an independent device stays constant underneath the Mass conservation on Energy and it is, the kinetic energy plus potential energy is just like a fixed (KE+PE=Standard). So, if KE improves, it is valid that PE declines.

If the PE is now at least then KE has been at the highest. It is also valid that KE is reduced as PE is increased as well as the maximum PE, the minimum KE.
