Answer:
Allotropes
Explanation:
Because it is the same element the chemical conposition is the same i.e. The atoms that make the substances are identical. Allotropes can be crystalline or amorphous and sometimes they can be varied in properties.
when we need to represent the magnetic field in a specific region where it is given that magnetic field lines are perpendicular to the plane and going inside the plane then we always use the concept of representation by "X"
here this symbol represents that field lines are going into the plane
it is also the uniform magnetic field always
so the correct answer would be
<u>Magnetic Field</u>
A its Stratosphere, Sorry I didn't see your answer, its bilogy I think not physics.. :)
Answer:
he fall movement we see that both the force is different from zero, and the torque is different from zero.
When analyzing the statements the d is true
Explanation:
Let's pose the solution of this problem, to be able to analyze the firm affirmations.
When the person is falling, the weight acts on them all the time, initially the rope has no force, but at the moment it begins to lash it exerts a force towards the top that is proportional to the lengthening of the rope.
The equation for this part is
Fe - W = m a
k x - mg = m a
As the axis of rotation is located at the top where they jump, there is a torque.
What is it
Fe y - W y = I α
angular and linear acceleration are related
a = α r
Fe y - W y = I a / r
In the fall movement we see that both the force is different from zero, and the torque is different from zero.
When analyzing the statements the d is true
Answer:
Period is 1.57 seconds
Explanation:
From simple harmonic motion :
T = 2π√(2.5÷10)
T = 0.25 × 2π
T = 1.57 s
