Answer:

The Axis Powers took these aggressive actions prior to the outbreak of World War II which include the invasion of Ethiopia, Manchuria, and the Rhineland.

Explanation:

Axis Powers: It was the coalition of Germany, Italy and Japan against the <em>Allied Powers</em> (the United States, the Soviet Union, Great Britain, and China) in World War II.

In 1930, the Japanese took control of railway track in Manchuria (a region in China) and in 1931, the Japan attacked the Chinese army claiming that the Chinese soldiers sabotaged the railway.
On 3 October 1935, Italy invaded the Ethiopia (former name: Abyssinia) in the leadership of <em>Mussolini </em>to expand its territories.
Germany in the leadership of Adolf Hitler occupied the Rhineland in 1937 by making excuse that the area is hostile and dangerous for them.

A 1.50-kilogram ball is attached to the end of a 0.520-meter string and swung in a circle. The velocity of the ball is 9.78 m/s.

Sedaia [141]

Answer:

F centripetal force (tension) = 275.9 N

Explanation:

Given data:

Mass = 1.50 kg

Radius = 0.520 m

Velocity of ball = 9.78 m/s

Tension = ?

Solution:

F centripetal force (tension) = m.v² / R

F centripetal force (tension) = 1.50 kg . (9.78 m/s)² / 0.520 m

F centripetal force (tension) = 1.50 kg . 95.65 m²/s² / 0.520 m

F centripetal force (tension) = 143.5 kg. m²/s² / 0.520 m

F centripetal force (tension) = 275.9 N

Use the Ref An aqueous solution of chromium(II) acetate has a concentration of 0.260 molal. The percent by mass of chromium(II)

poizon [28]

Answer:

The percent by mass of chromium(II) acetate in the solution is 4.42%.

Explanation:

Molality of the chromium(II) acetate solution = 0.260 m = 0.260 mol/kg

This means that in 1 kg of solution 0.260 moles of chromium(II) acetate are present.

1000 g = 1 kg

So, in 1000 grams of solution 0.260 moles of chromium(II) acetate are present.

Then in 100 grams of solution = $\frac{0.260 mol}{1000}\times 100=0.0260 mol$

Mass of 0.0260 moles chromium(II) acetate:

= 0.0260 mol × 170 g/mol = 4.42 g

$(w/w)\%=\frac{\text{mass of solute in 100 gram solution}}{100}\times 100$

$=\frac{4.42 g}{100 g}\times 100=4.42\%$

The percent by mass of chromium(II) acetate in the solution is 4.42%.
