Answer:
3 Volts
Explanation:
Using Ohm's Law
Voltage=current x resistance
V = I x R
V = 1.5 x 2
V = 3 V
At the frequency of 5 MHz, the period of the oscillations is 1/5meg. That's a period of 1/5 microsecond.
There are 5 full cycles in one full microsecond, and there are 2.5 full cycles in a 0.5 us pulse.
You'll have to decide for yourself how damped a pulse of 2.5 cycles is, because the parameters of the definition are corrupted in the question.

Answer:
5.A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
6.The Nazca plate is an oceanic plate, while the South American plate is continental. The fast moving Nazca plate is moving east towards the South American plate at a downward angle and converging. This process is called subduction, resulting in frequent earthquakes & production of the Andes Mountains.
7.The Nazca plate forms the southeastern part of the Pacific plate. The Nazca and the Pacific plate share both divergent and transform type of plate boundary. The Pacific and the Nazca plate are separating at an increasing rate of about 122-142mm/year.
8.Convection currents in the mantle and in the ocean are similar because they both are responsible for the shaping the Earth's surface. Two forces are behind the movement of Earth's huge land masses. Due to combined action of convection currents and gravity, Earth's plates are in constant motion.

Explanation:
The magnetic force acting on the charged particle in magnetic field is given by :
Here,
q is the charged particle
v is the speed of particle
B is magnetic field
is the angle between the v and B.
The correct statements for the magnetic force are :
- An electric charge moving perpendicular to a magnetic field experiences a magnetic force. In this case,
. It will experience maximum force. - The direction of the magnetic force acting on a moving electric charge in a magnetic field is perpendicular to the direction of motion.
- A magnetic force is exerted on an electric charge moving through a uniform magnetic field.
- The direction of the magnetic force acting on a moving charge in a magnetic field is perpendicular to the direction of the magnetic field.
