1.) The object's Velocity
Faster it goes, more kinetic energy it has
Answer:
M. Magnetism is a property of individual atoms.
Explanation:
when a magnet is broken into pieces the new pieces behave like the original magnet this observation shows that magnetism is the property of individual atoms.
Answer:
conduction electrons
Explanation:
Metallic bonding is a type of chemical bonding that rises from the electrostatic attractive force between conduction electrons and positively charged metal ions. It may be described as the sharing of free electrons among a structure of positively charged ions.
To solve this we are going to use the formula for ideal mechanical advantage:
where
is the machine mechanical advantage
is the input distance
is the output distance
We know for our problem that
and
. Lets replace those values in our formula to find
:
The ideal machine advantage of the machine is 3. The inventor is claiming that the actual mechanical advantage of the machine is 4. Since the actual mechanical advantage takes into account energy losses, it is always less than the ideal mechanical advantage.
We can conclude that the developer's claim is false.
Answer:
<h2>675 N</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 45 × 15
We have the final answer as
<h3>675 N</h3>
Hope this helps you
