Answer:
23.9m
Explanation:
step one:
This problem is on energy.
we can proceed by using the expression for potential energy to solve for height h
we know that
PE=mgh
given that
mass m= 5kg
PE= 1176 joules
step two:
we can substitute our data and find h
1176= 5*9.81*h
1176=49.05h
step three:
divide both sides by 49.05 we have
1176/49.05=h
h=23.9 m
The height of the tree is 23.9m
Part 1)
here we know that supply took 10 s to reach the ground
so here we will have
Part 2)
Here all the supply covered horizontal distance of 650 m in 10 s interval of time
so here we can say
As the chemical bonds are broken, the positions of electrons change, resulting in a product with properties that are different from the properties of the reactants. Various temperatures and catalysts are needed for different chemical reactions to occur. <span>During a chemical reaction, new substances are produced as existing bonds are broken, atoms are rearranged, and new bonds are formed.</span>
