The answer is:
A. They can be formed into wires.
B.They are shiny.
D. They are good conductors
E.can be easily shaped by hammering or pounding.
The explanation:
Let's see the characteristics of the most metals:
1) the most metals can be hit by a hammer and form a thin sheets without breaking and this called malleability.
for example: Aluminium and copper
2) They can form into a very thin wires and this called ductility
for example: silvar , Aluminium and copper.
3) The metal can conduct the heat and the electricity very easy and quick, this mean that the meals are good conductor for the heat and electricity.
4)The metals like gold can be used at jewellery because it is very shiny.
5) and answer C is wrong because most metals are solid at room temperature.
A since it’s the only one that makes sense! So A is correct.
The change in temperature is simply 50 / (9/5) = 27.777. We just throw out the 32 from the formula
Answer:
<h2>34.67 W</h2>
Explanation:
Power is the rate at which work is done and can be found by using the formula
p is the power in Watts (W)
w is the workdone in joules
t is time in s
but workdone = force × distance
From the question
force = 780 N
distance = 2 m
workdone = 780 × 2 = 1560 N
Since we now have the value of workdone we can find the power
We have
We have the final answer as
<h3>34.67 W</h3>
