an electric heater consumes 3.6MJ when connected to a 250V supply for 40minutes find the power rating of the heater and the current taken from supply
Answer:
Power rating of heater=1.5kw
Current taken from the supply=6A
Explanation:
Power(P)=Energy/Time
Where, electrical energy=3.6*10^6J and Time=40mins=40*60s
P=3.6*10^6J/40*60s
P=1500J/s or 1500watts
P=1.5kw
Current supply:
P=VI
Where, power(P)=1500watts,Voltage supply (V)=250volts, and current(I)=?
Making current (I) the subject of the formula :
I=P/V
I=1500watts/250volts=6A
Therefore, current taken from the supply is 6A.
The power rating of the heater is 1500 Watts and it takes a current of 6 Amps from the supply.
Explanation:The power of an electrical appliance like a heater can be calculated using the formula Power (P) = Energy (E) / Time (T), where Power is in Watts, Energy is in Joules, and Time is in seconds. Your heater consumes 3.6 Megajoules (MJ) in 40 minutes. Converting these to the units we require, we get 3,600,000 Joules and 2400 seconds.
P = E / T = 3,600,000 J / 2,400 s = 1500 Watts
Now about the current consumption, we can use the formula Current (I) = Power (P) / Voltage (V), where Current is in Amps and Voltage is in Volts. Given that the heater is connected to a 250V supply,
I = P/V = 1500W / 250V = 6 Amps
So, the power rating of the heater is 1500W, and it takes 6A from the supply.

can i join three 12 volts batteriesto give me 24 volts output
Answer:
YES
Explanation:
If we connect batteries in series then the output voltage is the sum of the individual voltage of each battery i.e if you connect three 12 volts batteries in series then their output voltage will be 12+12+12=36 volts, but the current rating of the batteries in series will be same of the individual battery rating in 'mah'.
But when we connect the batteries in parallel their voltage is not added but their current rating in mah is addition of their individual rating.
So, If you want 24 volts from three 12 volts battery then you can connect two of them in series and the other one in parallel with them this will give 24 volts and the current will be addition of the two series batteries and the third which is in parallel with them. You can use this configuration if current value is not a big factor.
the pressure of a car can be adjusted using what
Answer:
tyre pressure monitoring system (TPMS)
Explanation:
It very important to inflate your tyres to the specified pressure. So cultivate a habit to check and refill them once a month. Note that you can't tell if a tyre is underinflated just by looking at it. If it actually looks underinflated in a way. And you can't really rely on a tyre pressure monitoring system (TPMS) only to keep track. Most systems only warn you when the pressure is 25 percent below the manufacturer's recommended tyre pressure.
The phrase "positive to positive, negative to ground" is correct when jump starting a car.
A) TrueB) False
The correct answer is A; True.
Further Explanation:
This is a correct phrase that is important to learn when owning any type of vehicle. When a car battery is dead, it can usually be jump started by using another cars battery or a portable battery charger. It is extremely important to put the positive battery cable on the positive battery post. Then the negative cable will be placed on the negative car battery post and the negative ground wire can be anywhere on the car except on the battery.
The car needs to be connected properly for a few minutes before trying to start the car. This helps the car battery to get enough "juice" to start. If the battery cables are placed wrong this can cause sparks to come out of the cables/battery and cause bodily harm.

Answer:
224.8125 N
Explanation:
Using the attached diagram, then we can work the answer as follows
Taking moments about 275 mm from point A
[tex]P\times 1500=\frac {mg}{2}\times 275mm[/tex]
Where m is the mass, P is the load, g is acceleration due to gravity
[tex]P=\frac {250\times 9.81\times 275mm}{2\times 1500mm}=224.8125 N[/tex]

A local reaction is when a chemical enters the bloodstream?
false because skin contact with a chemical may result in a local reaction, such as a burn or rash, or absorption into the bloodstream. Absorption into the bloodstream may then allow the chemical to cause toxic effects on other parts of the body.
False
Local reactions can be described as a type of reaction that affects the surface of the skin. These different reactions can be in the form of skin rashes, boils, pimples and so on.
These local reactions can originate through eating foods that are not accepted or allergic to the body. Also, these reactions can come from body creams that can cause a bad reaction to the skin.
The can also come from a prescribed drug that is not suitable in the body. Hence the reason why we should know what food, cream or drug is good for the body.
