Sterling silver is an alloy of silver made up of around 93% silver and 7% other metals, such as copper, all blended together to form the substance. what type of mixture is sterling silver?

An alloy is a mixture of two or more elements that are combined in varying proportions.

A mixture can be categorised as a homogenous or heterogenous.

A homogenous mixture is one in which the different components have the same composition throughout and exist in a single phase. In contrast, in a heterogenous mixture, the components have varying composition and might not be evenly blended to form a single phase.

In Sterling silver 93% silver along with 7% other metals are uniformly mixed to form a homogenous mixture.

a homogeneous mixture, because the different componets are mixed evenly within the substance

the practice of taking someone else's work or ideas and passing them off as one's own.

explanation:

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
