5. Consider two glasses, one filled with water and the other half-full, with the water in the two glasses being at the same temp

erature. In which glass are the water molecules moving faster? In which is there greater internal energy? In which will more heat be required to increase the temperature by 1 degree C?

Answer:

Explanation:

In the glass full of water, volume and therefore mass of water is more than that in  glass, half filled with water. Temperature of water is same . The velocity of molecules depend on the temperature of the material. Since temperature of water is same in both the glasses, the velocity of water molecules will be same in both the glasses.

. The internal energy per unit volume or mass  too is dependent on the temperature . Since the volume of water is more in the fully filled glass , internal energy too will be more of this glass.

Heat required to increase unit degree temperature of unit mass of any thing is called specific heat . In case of water one calorie of heat is required to increase temperature by  one degree C in mass of  one gram of water .Since,  gram of water is more in case of fully filled glass , more heat will be required to increase the temperature by one  degree C of water in fully filled glass.

A bullet is fired with a muzzle velocity of 1178 ft/sec from a gun aimed at an angle of 26° above the horizontal. Find the horiz
dalvyx [7]

Answer:

1058.78 ft/sec

Explanation:

Horizontal Component of Velocity; This is the velocity of a body that act on the horizontal axis. I.e Velocity along x-axis

The horizontal velocity of a body can be calculated as shown below.\

Vh = Vcos∅.......................... Equation 1

Where Vh = horizontal component of the velocity, V = The velocity acting between the horizontal and the vertical axis, ∅ = Angle the velocity make with the horizontal.

Given: V = 1178 ft/sec, ∅ = 26°

Substitute into equation 1

Vh = 1178cos26

Vh = 1178(0.8988)

Vh = 1058.78 ft/sec

Hence the horizontal component of the velocity = 1058.78 ft/sec

Explain how an alpine glacier can change the topography of a mountainous area
igor_vitrenko [27]
<span>An alpine glacier can change the topography of a mountainous area through Glacial Erosion and Glacial Deposition. Glaciers are agents of erosion, it can pick up and carry large rocks and sediments. In the process, a deep cavity or hole can form when the glacier plucks a big rock from where it passed. Glaciers have shaped many Mountain Ranges and have created distinct landforms by its erosion process.  In Glacial Deposition, as glaciers melt, it deposits all that it carried and a landform is developed.</span>
