Calculate velocity at halfway to the ground.
vfinal = root 2ad
v = root (2*9.81m/s^2*25)
v = 69.367175234 m/s
Kinetic energy = 1/2mv^2
Kinetic energy = 1/2 * (69.367175234 m/s^s^2
Ek = 2405.9025 Joules
The right answer is "Strong nuclear force"
That matter s indivisible and indestructible. This is because they discovered that certain elements, thought to be indivisible, can breakdown by radioactive decay and emit smaller, high energy particles and/or photons.
Answer:
Cost of energy = N230.4
Explanation:
Given the following data;
Time = 8 hours
Power = 1200 W
Voltage = 240 V
Cost of energy = N24
To find the cost of running an electric laundry iron;
First of all, we would determine the energy consumption of the iron.
Energy = power * time
Energy = 1200 * 8
Energy = 9600 Watt-hour = 9.6 Kwh (1 Kilowatts is equal to 1000 watts).
Next, we find the cost of energy;
Cost of energy = 9.6 * 24
Cost of energy = N230.4
