Answer: vf= 364 m/s
Explanation: Use the formula for acceleration:
a= vf - vi / t
Derive for vf:
vf =( at )+ vi
= 5.4 m/s² ( 55s) + 67 m/s
= 364 m/s
Answer:
Radiative transport
Explanation:
Radiative transportation takes place extensively in the core of the sun. It produces solar energy which are emitted outward from the core of the sun, and it comprises more than 70% of the sun's heat energy. At the core of the sun, the process of nuclear fusion takes where the hydrogen atoms combines with one another, and forms helium, and during this process, it releases a large amount of energy. The photons continuously interacts with the ions (or atoms) and releases this energy to the particles and the excited particles converts the excess amount of energy into another photon which are carried outward by the process of radiative transport.

Answer:2H2O2 → 2H2O + O2
Explanation:
For a chemical equation to be balanced, the number of moles of each element at the reactant must be equal to that of the product.
According to the equation given
H2O2 → H2O + O2
There are two hydrogen atoms with two oxygen atoms at the reactant and 2hydrogen and 3oxygen at the product which shows the equation is not balanced. To balance this,
We will add 2 moles to H2O2 at the reactant and 2 moles to H2O at the product to give;
2H2O2 → 2H2O + O2 (Balanced equation)
As we can see that we now have 4 moles of Hydrogen and 4 moles of oxygen at both reactant and product making the equation balanced.
The force he must exert is 300 N
