<span>d. renewable energy
</span>
<u>Explanation</u>
Energy can be said to be one of the most basic commodity in the 21st century. Every household uses energy in almost all its doing eg. cooking lighting, cleaning, entertainment such televisions and radios, communication etc.
For this reason, the scientist have to find the most sustainable source of energy. Some are not sustainable as they can be used up and other pollute the environment.
By the year 2030, the most expected source of energy to have the highest rate of consumption is renewable energy.
Answer:
Cost = 40 fills
Explanation:
First, we will calculate the total power consumed by all appliances:
Now, we will calculate the energy required:
Now, for the cost we use the following formula:
<u>Cost = 40 fills</u>
Acceleration = V/t
First set velocity to m/s
V = 72.42 m/s
Now we divide velocity by time
A = 72.42/39.5
A = 1.83 m/s^2
From the calculation, the horizontal distance is 310 m.
<h3>What is the range of a projectile?</h3>
A projectile has to do with an object that is thrown at an angle. Now we know that the range of the projectile is given by the formula; R = u^2sin2θ/g
We we know that;
g = acceleration due to gravity
θ = angle
u = velocity
R = (60)^2 sin2(30)/10
R = 310 m
