1 answer:

<span>While you're going to the store, your acceleration changes. Some times it increases your overall speed sometimes it reduces it. Constant acceleration does not occur because it would mean that you would constantly accelerate and eventually go past the store. Even reduction of speed is a type of acceleration in physics. When you reach it, we can then calculate how much your velocity was on average and analyze how changing acceleration would've affected it.</span>

One of the great upcoming sports in the Olympics is the sport of curling. Write a brief essay on the uses of momentum collisions

Svetllana [295]

The Olympic sport of curling is one that is practically designed to show Physics in motion. Curling is a sport in which two teams alternate sliding smoothed stone pucks down an ice rink court with the intent to seat their stone closest to the center of the target (called the house). Each team has eight stones, meaning that the team that goes second has the (could be) massive advantage of sending the last stone.

The mass of the stone is important in that the more massive a stone (m) and the speed at which it travels (v) dictates it's momentum (momentum=mxv). As the curling stone slides down the ice (which is relatively frictionless unless acted upon by other players or objects) and having inertia, continues in it's straight course (again, unless acted upon by outside forces). If the stone hits another stone, it transfers some of its momentum in an elastic collision to that stone and the original stone is deflected in a calculable manner.

Collisions are used in the game to either clear opponent's stones from the house or out of their defensive positions, or to make adjustments to one's stones present in the house, all based on the momentum of the moving stone, and its transference.

A 3.8 car is traveling at 19 m/s . What is it's momentum?

pashok25 [27]

The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v).

If you found a line of volcanic peaks a few hundred miles long in which the volcanoes were progressively older toward one end of

Basile [38]

The geological process that could be responsible for this phenomenon would be the plate tectonics. The plate tectonic theories are believed to be the cause of the landforms forming on the earth's surface. What is described in the questions would be an oceanic ridge which is formed from converging oceanic crusts.

What is the intensity of a sound with a sound intensity level (SIL) 67 dB, in units of W/m^2?

vfiekz [6]

Answer:

The intensity of sound (I) = 3.16 x 10⁻⁶ W/m²

Explanation:

We have expression for sound intensity level (SIL),

$L=10log_{10}\left ( \frac{I}{I_0}\right )$
