4/5 miles times 2 is 8/5 that is the speed in miles per hour
Side of square = Radius of circle = 4cm
Area of full circle
= πr²
= (22/7) × 4cm × 4cm
= 352/7 cm²
Area of the quarter of circle
= Area of full circle/4
= (352/7)/4
= (352/7) × (1/4)
= 352/28
= 12.571 {approximately}
Answer:
G.P.E = 1.725 Joules
Step-by-step explanation:
Given the following data;
Mass = 0.008 kg
Height, h = 22m
To find the gravitational potential energy;
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;
Where;
G.P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
We know that acceleration due to gravity is equal to 9.8m/s²
Substituting into the formula, we have;
GPE = 0.008 * 9.8 * 22
GPE = 1.725 Joules
