What would the single sample Cohen's d value be if the difference in sample mean and hypothesized mean was 16, and the sample st

ELEN [110]

Answer:

Explanation:

To calculate an effect size, called Cohen's d , for the one-sample t-test you need to divide the mean difference by the standard deviation of the difference, as shown below. Note that, here: sd(x-mu) = sd(x) . μ is the theoretical mean against which the mean of our sample is compared (default value is mu = 0).

A boy carries a 50 N box up a flight of stairs 10-m high. How much potential energy has the box gained?

almond37 [142]

Answer:

Potential energy, P = 500 J

Explanation:

We have,

Weight of the box, W = 50 N

Height of the stairs, h = 10 m

It is required to find the potential energy gained by the box. The potential energy is possessed by an object due to its height. The formula of potential energy is given by :

$P=mgh$

g is acceleration due to gravity

$P=50\ N\times 10\ m\\\\P=500\ J$

So, the potential energy of 500 J is gained by the box.
