Answer:

The statemente <u><em>"If voltage is increased, and no other changes are made, power will increase"</em></u> describes the relationship between power, voltage, and current.

Explanation:

The flow of electricity through an object, such as a cable, is known as current (I). Its unit of measure is amps (A). Then the current is a measure of the speed at which the charge passes through a given reference point in a specified direction.

The conductive force (electrical pressure) after the flow of a current is known as voltage and is measured in volts (V) (the voltage can also be referred to as the potential difference or electromotive force). That is, voltage is a measure of the work required to move a load from one point to another.

Power is the speed or speed with which energy is consumed. Energy being the capacity of any electrical mechanism or device to perform a job, power can also be defined as the energy developed or consumed in a unit of time. Its unit of measure is the Watt. Since power is energy per unit of time, 1 W equals 1 joule / second.

Watt's law applies to electrical circuits and establishes that the electrical power P supplied by a circuit element is directly proportional to the product between the voltage of the power supply V of the circuit and the current intensity I flowing through it.

Mathematically, Watt's law expresses:

P = V.I

In the previous expression, you will be able to observe that if the voltage is increased and other changes are not made, that is to say that the current I does not vary, the power will increase.

<u><em>The statemente "If voltage is increased, and no other changes are made, power will increase" describes the relationship between power, voltage, and current.</em></u>

What is the radius of a communications satellite’s orbital path that is in a uniform circular orbit around Earth and has a perio
pantera1 [17]
If the period of a satellite is T=24 h = 86400 s that means it is in geostationary orbit around Earth. That means that the force of gravity Fg and the centripetal force Fcp are equal:

Fg=Fcp

m*g=m*(v²/R),
 
where m is mass, v is the velocity of the satelite and R is the height of the satellite and g=G*(M/r²), where G=6.67*10^-11 m³ kg⁻¹ s⁻², M is the mass of the Earth and r is the distance from the satellite. 

Masses cancel out and we have:

G*(M/r²)=v²/R, R=r so:

G*(M/r)=v²

r=G*(M/v²), since v=ωr it means v²=ω²r² and we plug it in,

r=G*(M/ω²r²),

r³=G*(M/ω²), ω=2π/T, it means ω²=4π²/T² and we plug that in:

r³=G*(M/(4π²/T²)), and finally we take the third root to get r:

r=∛{(G*M*T²)/(4π²)}=4.226*10^7 m= 42 260 km which is the height of a geostationary satellite.

In a race, you run 3000 meters east in 21 minutes. What is your velocity in km/min?
STALIN [3.7K]

velocity = distance / time      v= d/t          firstly you change 3000 m into km     distance  D = 3000/1000  = 3 km             secondly   time t = 21 min      using velocity formula v = d/t       = 3 km/21min       =0.142km/min

A bus is traveling with a uniform acceleration of 2.75 meters/second2. If the initial velocity of the bus is 16.5 meters/second,
Kaylis [27]
<span>The velocity will be 41.25 m/s2 after 9 seconds. To find velocity after a specific time period, multiply the acceleration (2.75) times the number of seconds (9) to receive 24.75 m/s, then add that to the initial velocity of 16.5 m/s. 24.75 + 16.5 = 41.25 m/s2.</span>

The molecular mass of sodium oxide (Na2O) is
tresset_1 [31]
<span>The answer is 62 u. The molecular mass of a molecule (Mr) is the sum of atomic masses (Ar) of its elements. Ar(Na) = 23 u. Ar(O) = 16 u. Therefore, the molecular mass of sodium oxide is 62 u: Mr(Na2O) = 2 * Ar(Na) + Ar(O) = 2 * 23 u + 16 u = 46 + 16 = 62 u.</span>
