Answer:
kinetic energy is 1/2mv^2.
which is 1/2×5×10^2.
1/2×5×100=
250J.
Answer:
Yes, because a banana is not like a boomerang. It will go straight if you aim straight.
Answer:
t = 1min
Explanation:

The correct option is D.
In the equation given above, Q stands for quantity of heat and J stands for Joule, which is the unit for measuring heat and the quantity of the heat given is negative. The negativity of the value of the heat given shows that the reaction is an exothermic reaction.
There are basically two types of reaction in term of heat involved, these are endothermic and exothermic reaction. An exothermic reaction is a type of reaction which gives out heat to the environment. Because of this, the energy value of the product is always lesser than that of the reactant. The difference between the energy of the products and the energy of the reactants is called enthalpy change of the reaction. For an exothermic reaction, the enthalpy change is always negative.
