Acceleration due to gravity = 2.6m/s²

Length of building = d = 88.3m

<span>Time he needed before she hits the ground = ?
 we can find the time by using the formula;</span>

D = 1/2at²

Now putting the value;

<span>88.3 = (1/2) a t</span>²<span>

88.3 = 1/2 x 23.6 x t</span>²

t² = 88.3 / 11.8

= 7.48

<span>t = 2.735 seconds

At what common temperature will a block of wood and a block of metal both feel neither hot nor cold to the touch ?
Anastaziya [24]

When you touch an object and heat flows OUT of it, INTO your finger, you say the object feels hot.

When you touch an object and heat flows INTO it, OUT of your finger, you say the object feels cold.

If the object has the same temperature as your finger ... <em>around the mid-90s</em> ... then no heat flows in or out of your finger when you touch the object, and the object doesn't feel hot or cold.
