Answer:
energy
Explanation:
waves can move distances without transferring any matter, so the answer is energy
Answer:
The moment of inertia will be increased by a factor of 1575
Explanation:
Let the moment of inertia of a wheel be given as;
where;
I is the moment of inertia of the wheel
m is mass of the wheel
r is radius of the wheel
when the mass is increased by a factor of 7 and the radius is increased by a factor of 15
Thus, the moment of inertia will be increased by a factor of 1575
If time (t), acceleration(a) and initial velocity (Vi) is given distance can be find by
S = (Vi)t + (1/2) at²
If both velocities initial velocity an final velocity is given then formula will be
2aS = (Vf)²- (Vi²)
Where S is the distance.
The answer would be "the vector sum of forces acting on a particle or body."
Hope that helped ^^
Radioactivity is a part of our earth - it has existed all along. Naturally occurring radioactive materials are present in its crust, the floors and walls of our homes, schools, or offices and in the food we eat and drink. There are radioactive gases in the air we breathe. Our own bodies - muscles, bones, and tissue - contain naturally occurring radioactive elements.
