Kinetic energy is the energy possessed by an object when that object is moving in space. The higher the mass of an object or higher the speed of an object the higher the kinetic energy will be.
So to calculate the Kinetic Energy we can use the following formula
K.E=(1/2)*m*v^2
Inserting the values in formula gives:
K.E=1/2*7.26*2^2
14.52J
This is the final answer which gives the kinetic energy of the ball.
The role of hormones in maintaining homeostasis in living things is that to keep a constant internal environment. I really hope this helps!
Answer: C
1054 g
Explanation:
Given that the object is in the shape of semi sphere with diameter of 8.2cm. And density of 7.3g/cm^3.
From definition of density,
Density = mass/volume
Volume of a half - sphere = 2/3πr^3
Volume = 2/3 × 3.143 × 4.1^3
Volume = 144.35 cm^3
Let make mass the subject of formula
Mass = Density × volume
Mass = 7.3 × 144.35
Mass = 1053.74g
The mass of the paperweight, in grams is 1054
