I am pretty sure it’s A
The cue exerts force onto the white ball which pushes the blue ball into the direction of the hole.
Answer:
c. emission of electromagnetic radiation.
Explanation:
When an atom changes its state from an excited one to the ground state, it means that the atom is changing from a state with higher energy to a state of lower energy.
This can occur, for instance, in the presence of an electronic transition (an electron moving from a higher energy level to a lower energy state) or of a nuclear transition (the nucleus get de-excited). In both cases, since the total energy must be conserved, there must be energy released. This energy is released as a photon (electromagnetic radiation), whose energy is equal to the difference between the two energy levels involved in the transition.
The velocity curve is such in which the x-axis is the velocity and the y is the time. The distance traveled by the object is calculated by multiplying velocity and time. Thus, in the velocity curve, the distance can be easily calculated if we know where to look.
Yes, it possible to orient a current loop in a uniform magnetic field such that the loop will not tend to rotate.
The forces on opposing sides of the loop would be equal in magnitude and opposite in direction if the magnetic field is pointed perpendicular to the plane of the loop; yet, there will be no net torque produced on the loop. In a constant magnetic field, there is no torque experienced by a current loop. A current carrying loop in a homogeneous magnetic field will never exert any net magnetic force. In a constant magnetic field, there is no torque experienced by a current loop. Due to the zero torque on the loop in this position, the plane of the loop is parallel to the direction of the magnetic field.
