When silver is poured into the mould the it will solidify
In this process the phase of the Silver block will change from liquid to solid.
This phase change will lead to release in heat and this heat is known as latent heat of fusion.
The formula to find the latent heat of fusion is given as
here given that
now we can find the heat released
So it will release total heat of 55.5 kJ when it will solidify
Silver: bonds with other atoms because of the weak forces of the valence electrons
FALSE - The strong forces of the valence electrons is actually the reason why silver bonds with other atoms.
Water: bonds allow for liquid state at room temperature and prevent conduction
FALSE - Water is a good conductor.
Carbon: bonds with other atoms through strong shared electrical bonds
TRUE - Carbon shares covalent bonds with other atoms.
Niobium: bonds allow for a strong conductivity found in stainless steel
FALSE - Iron and Carbon make up steel.
Answer:
frequency and amplitude increases
The velocity of the teddy bear as it strikes the ground is 7.67 m/s.
<h3>
Velocity of the teddy when it strikes the ground</h3>
The velocity of the teddy when it strikes the ground is calculated from principle of conservation of energy as shown below.
K.E(bottom) = P.E(top)
¹/₂mv² = mgh
v² = 2gh
v = √2gh
where;
- h is height of fall of the teddy
- g is acceleration due to gravity
v = √(2 x 9.8 x 3)
v = 7.67 m/s
Thus, the velocity of the teddy bear as it strikes the ground is 7.67 m/s.
