Answer:
7.69km/hr due east
Explanation:
Given parameters:
Displacement due west = 3km
Displacement due east = 2km
Time taken = 8 minutes
Unknown:
Average velocity = ?
Solution:
Average velocity is the rate of change of displacement with time.
Velocity = 
Displacement is deals with the start and the end;
Here, displacement = 3km - 2km = 1km due east
Time = 8min
60min = 1hr
8min =
= 0.13hr
Average velocity =
= 7.69km/hr due east
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat, may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical
Answer:
Gravitational energy
kinetic energy
Electrical energy
Light energy
Explanation:
When water stored in dams falls freely, the potential energy stored is converted into kinetic energy.
So, it is gravitational energy
As turbines move, it is kinetic energy.
Electricity is produced, it is electrical energy.
For lightening, it is light energy.
Energy is conserved, Energy can neither be created nor be destroyed. It can transform from one form of energy into another.
Explanation:
Given that,
Two resistors of 10 ohms and 15 ohms are connected.
In series combination, the equivalent resistance is given by :

In parallel combination, the equivalent resistance is given by :

Hence, this is the required solution.
You would do 450 divided by 3,600, and your answer would be 0.125nm/ps :)))
