Answer:

Evaporation

Explanation:

Salt is very soluble in water. Hence in other to be able to recover salt from a homogeneous mixture of water and salt, the mixture is heated so that water molecules can evaporate leaving the salt behind in the evaporating dish.

To separate a mixture of salt and water, you can try first by using filter paper hen with the extra water part set it out to the window so that the salt water evaporates and only the salt is remaining.

A plane flies from base camp to lake a, 205 km away in the direction 20.0° north of east. after dropping off supplies it flies
miss Akunina [59]
Draw a diagram to illustrate the problem as shown in the figure below.

Camp A  is 20° north of east from the camp, therefore
m∠CAB = 80°
where C => base camp.

Let d = distance from lake B to the base camp, at x° west of south.
Apply the Law of Cosines to determine d.
d² = 205² + 175² - 2*205*175*cos80⁰
     = 6.0191 x 10⁴
d = 245.338 km

Apply the Law of Sines to obtain
\frac{sin(x+30)}{205}= \frac{sin80^{o}}{245.338}\\ \\ sin(x+30)=( \frac{205}{245.338})sin80^{o}=   0.8229
x+30 = sin⁻¹ 0.8229 = 55.4°
x = 25.4°

Answer:
The distance from lake B to base camp is 243.3km (nearest tenth).
The direction is 25.4° west of south.

Pls help with these two last questions
zhenek [66]

Answer:

F = 50[N], to the left.

v = 10.52 [m/s]

Explanation:

<u>First problem</u>

<u />

In order to solve this problem we must apply Newton's laws, in such a way that we must perform a summation of forces on the horizontal axis. In this way we will analyze each force and the direction of action.

The offensive player is applying a force of 100N to the right, while the defensive player applies a force of 150N to the left. In this way performing the summation of forces we have.

100 - 150 = F

F = - 50 [N]

Note: The negative sign indicates that the resulting force is to the left.

<u>Second problem</u>

<u />

We must remember that the definition of speed is equal to the relationship between distance over time.

x = distance = 100 [m]

t = time = 9.5 [s]

v = x/t

v = 100/9.5

v = 10.52 [m/s]

<u />
