The heat from your hand causes the ice molecules to heat up and become more active. This lowers the stability of the ice cube compound causing it to melt.
Answer:
The object will rotate with constant angular acceleration
Explanation:
According to the Newton's Second Law for Whenever there is more than one torque acting on a rigid body that posses fixed axis, the moment of inertia as well as the angular acceleration is equals or proportional to the summation of the torques. It gives details on the relationship between rotational kinematics and torque as well as moment of inertia. This can be represented by the below equation.
∑iτi=Iα.
.Therefore when constant net torque is applied to object that is rotating, the object will rotate with constant angular acceleration
The letter that answers this question correctly is E .
Answer:
Explanation:
A differential equation that contain a term with di(t)/dt is in a RL circuit. Here we have
where vr is the voltage in the resistance, vi is the voltage in the inductance and vb is the source voltage. But also we have that
where L is the inductance of the circuit, r is the resistance an i is the current. By replacing we have the differential equation
