Answer:
caves are mainly formed by water or in some other cases limestone.
The answer will be 50N.
This is because the spring reads weight and weight is mass times acceleration due to gravity.5kg*10m/s2=50N
Answer:
Explanation:
Given:
The area of the house
The height of the house
We need to find the volume of a typical house.
Solution:
We find the volume of the house by multiplying the area of the house and height of the house.
Area and height of the house are known, so we substitute these value in above equation.
Now we convert the unit from feet to meter.
Divide the volume by 3.2808 for
Therefore, the volume of the house is
Answer:
Rotational kinetic energy = 0.099 J
Translational kinetic energy = 200 J
The moment of inertia of a solid sphere is .
Explanation:
Rotational kinetic energy is given by
where <em>I</em> is the moment of inertia and <em>ω</em> is the angular speed.
For a solid sphere,
where <em>m</em> is its mass and <em>r</em> is its radius.
From the question,
<em>ω</em> = 49 rad/s
<em>m</em> = 0.15 kg
<em>r</em> = 3.7 cm = 0.037 m
Translational kinetic energy is given by
where <em>v</em> is the linear speed.
