Elaborate rehearsal involves organizing and breaking down information into easier groups to expand capacity. Rehearsal is the verbal repetition of information. These techniques are especially important for the improvement of long-term memory.
Six strategies of elaborate rehearsal are:
1. Rephrase information into your own words.
2. Create your own study questions and answer them.
3. Use images to help you.
4. Group terms that are of the same topic together.
5. Use a mnemonic strategy.
6. Space our your learning and don't try to cram in on sitting.
Answer:
Some work input is lost to friction
Explanation:
The efficiency of a machine is defined as:
(1)
where
is the work output
is the work input
Due to the law of conservation of energy, the work output can never be larger than the work input (because energy cannot be created). Moreover, in real machines part of the work input is lost due to the presence of frictions: as a result, part of the energy in input is converted into thermal energy or other forms of energy, and so the work output is smaller than the work input, and so the ratio (1) becomes less than 1, and so the efficiency is less than 100%.
The simulation hypothesis<span> contends that reality is in fact a simulation (most likely a </span>computer simulation<span>), of which we, the simulants, are totally unaware. Some versions rely on the development of simulated reality, a fictional technology.</span>
Explanation:
The boat's velocity relative to the water is 6.10 m/s, and the water's velocity relative to the shore is 1.95 m/s. We want the boat's velocity relative to the shore to be perpendicular to the shore.
If we say that θ is the angle the boat makes with the shore, then:
6.10 cos θ - 1.95 = 0
6.10 cos θ = 1.95
cos θ = 1.95 / 6.10
θ = 71.4°
The boat should be steered 71.4° relative to the shore, or 18.6° relative to the vertical.
Answer:
D
Explanation:
He is storing energy to throw it.
Potential Energy = Stored Energy
