Answer:
1. When a cold air mass and a warm air mass meet but are at a standstill, the boundary is called stationary front.
2. If warm or more humid air presses forward and colder or drier air draws back, the boundary is called warm front.
3. If colder or drier air presses forward and warmer or more humid air draws back, the boundary is called cold front.
4. Sometimes a warm air mass can get caught between two cold fronts, which can force the warm air up into a wedge shape is called occluded front.
The angle theta of the spring is 31 degrees. To solve for this, show the equation which is equal to the 10lb ball. With this, the unknown will be the angle. Then transpose/transfer the terms in order to isolate the variable for the angle. First solve for s, then solve for angle theta. You will come up with s = .5849 ft and angle theta = 31.2629 or 31 degrees. Hope this helps.
Answer:
True
Explanation:
Limestone is a carbonate chemical sedimentary rock often chemically called calcium carbonate.
The mineral calcium carbonate makes up the framework of this rock that has become the staple material used for cement production.
Chemically, the formula is given as CaCO₃. The rock accumulates from the a rich deposit of calcite, which is the mineral that is made up of calcium carbonate to form the limestone.
CaCO₃ - Calcite - Limestone
compound mineral rock
Limestone is a rock and the compound it is made up of is calcium carbonate. In some cases, a Ca-Mg carbonate occurs with limestone and it is called a dolomite.
