Answer:
1- The acceleration of the object is larger in magnitude the smaller the radius of the circle.
Explanation:
The acceleration of an object in a circular path is
As can be seen from the equation, if the radius of the circle is decreases, the magnitude of the acceleration increases.
As for the direction of the acceleration, it is always towards the center, and it is always perpendicular to the direction of the velocity.

Answer:
The correct answer is;
Change of phase.
Explanation:
When the physical state in which a substance exists in nature changes to another physical state such as a change from solid state to a liquid stat or from a liquid state to a gaseous state, the substance is said to have undergone a phase change, or phase transformation.
The state of a substance will change, depending on the surrounding temperature and the applied pressure and the energy required for the substance to change its state is known as latent heat.
The observed plateaus are periods the latent heat is absorbed to completely change the phase of the substance.
<em>A clamp-type measuring instrument operates on the principle of; </em>

Answer:
d= 1.5 g/cm3
Explanation:
datos
m= 30g
v= 20cm3
d=?
formula
d= m / v
solución
d= 30g / 20cm3 = 1.5g/cm3
