To deal with resistance to collectivization, Stalin created a famine in which country?

In 1935, to shore up his “strong man” image at home, Mussolini invaded which of the following countries?

200 000 J of heat is added to 0.500 kg of solid ice originally at 0.0 ◦C. If the heat completely melts the ice, what will the final temperature (in Celsius) of the resulting liquid water be? (Lf = 3.33 × 105 J/kg, cw = 4 186 J/(kg·◦C)).

At a rock concert, the sound engineer turns up the master volume so that the physical intensity (W/m^2) of the sound waves increases by a factor of 1 000. How does the sound level in decibels (dB) change?

What is the molar mass of an unknown ideal gas if its root-mean-square speed is 1 580 m/s at a temperature of 400 K? (R = 8.314 J/(mol·K)

A simple pendulum has a period of 3.0 seconds on Earth. If an astronaut takes this pendulum to a planet where the acceleration due to gravity is 1/9th of Earth’s acceleration due to gravity on its surface, what will its new period be?

Water flows through a horizontal pipe. In a wide section (A1 = 0.0600 m^2), the speed is 3.00 m/s and the (absolute) pressure is 250 000 Pa. In a narrow section, the area is A2 = 0.0200 m^2. Assuming water density is 1 000 kg/m^3, what is the pressure in the narrow section?

4.00 moles of an ideal gas are held at a temperature of 400 K and a volume of 0.0500 m^3. What is the pressure of the gas? (R = 8.314 J/(mol·K)).

A 3.00 kg mass is swung in a vertical circle of radius 1.50 m. If its speed at the very bottom of the circle is 6.00 m/s, what is the tension in the string? (Assume g = 9.80 m/s^2).

A stone is thrown horizontally off a cliff with an initial speed of 20.0 m/s. It hits the ground 60.0 m horizontally away from the base. How high is the cliff? (Assume g = 9.80 m/s^2).
