c) only from warmer areas to colder areas.

The second principle of thermodynamics states that heat can only flow from a hotter body to a cooler one. Specifically, Clausius statement says that is not possible for heat to move by itself from a lower temperature body to a higher temperature body.

The gravitational force between two objects is 1600 N. What will be the gravitational force between the objects if the distance

goldfiish [28.3K]

3200 N
1600X2= 3200
It doubles so you multiply 3200 by 2

Determine the launch speed of a horizontally launched cannonball that lands 26.3

nlexa [21]

Answer:

The cannon has an initial speed of 13.25 m/s.

Explanation:

The launched cannonball is an example of a projectile. Thus, its launch speed can be determined by the application of the formula;

R = u $\sqrt{\frac{2H}{g} }$

Where: R is the range of the projectile, u is its initial speed, H is the height of the cliff and g is the gravitaty.

R = 26.3 m, H = 19.3 m, g = 9.8 m/ $s^{2}$ .

So that:

26.3 = u $\sqrt{\frac{2*19.3}{9.8} }$

$(26.3)^{2}$ = $u^{2}$ x $\frac{38.6}{9.8}$

691.69 = $u^{2}$ x $\frac{38.6}{9.8}$

$u^{2}$ = $\frac{691.69*9.8}{38.6}$

= $\frac{6778.562}{38.6}$

$u^{2}$ = 175.6104

⇒ u = $\sqrt{175.6104}$

= 13.2518

u = 13.25 m/s

The initial speed of the cannon is 13.25 m/s.

no risk of damage.

-- Most of the upper part of the state is considered to be at risk
for only minor damage.

-- A tiny part of the state, in the 'Big Bend' region in the west, is
considered to be at risk for moderate damage.
