Answer:
The voltage is V = 37.5 [V]
Explanation:
To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the current by the resistance.
V = I*R
where:
V = voltage [Volt]
I = current = 0.25[amp]
R = resistance = 150 [ohm]
V = 0.25*150 = 37.5 [V]
Answer:

Given
Mass of child 
speed of child is 
Moment of inertia of merry go round is 
radius 
Conserving the angular momentum
Answer:
Explanation:
Given
mass of ship =1240 kg
height=37 m
(a)Work done by Tension in cable+work done by gravity =0
Work done by gravity =change in potential energy of mass
Thus work done by tension=449.624 kJ
(b)work done by force of gravity
=-449.624 kJ
A) GPS monitoring of plate speeds and movements.
Explanation:
The most recent evidence supporting the theory of plate tectonics would be GPS monitoring of plate speeds and movements.
A GPS is a Global Positioning System made up of series of components.
- Plate tectonics theory is the movement of the earth's lithosphere relative to one another.
- The recent advances uses a GPS system to monitor real-time movement of the plates.
- The GPS system is made up of a system of satellite in space that communicates real-times locations to sensors on the earth surface.
- From the sensors, observatory stations can know and duly observe how plates are moving.

Answer:
It is a measure of the electric force per unit charge on a test charge.
Explanation:
The magnitude of the electric field is defined as the force per charge on the test charge.
Since we define electric field as the force per charge, it will have the units of force divided by the unit of charge. This implies that the SI unit of electric field is given as Newton/Coulomb (N/C).
