Answer:
Resistance, R = 13 ohms
Explanation:
The Ohm's law gives the direct relationship between the voltage, current and the resistance of the device. The relation is as follows :
Where
I is the current
r is the resistance
The value of resistance is given by :
According to given data,
Voltage of the circuit, V = 130 V
Current rating of the circuit, I = 10 A
Resistance of the device,
R = 13 ohms
So, the resistance of the device is 13 ohms. Hence, this is the required solution.
When a star collapses to form a black hole,
its mass increases, that is letter C. One example of this is the Big Bang
Theory.

It is by no doubt that our universe had had its own
starting point but how it really started became a debate for the scientists
over the past centuries. From theories such as Ekpyrotic theory, White Holes,
Matrix theory, and Quantum theory, the Big Bang theory is the theory mostly
accepted by scientists. According to the theory, the universe started as a
singularity, that is, from a black hole under extreme gravitational pressure
and expanded (instead of exploded) and cooled. Its cooling, according to the
theory, is still happening now as of the moment.</span>
It’s 25 because I already took the testing
Answer:
1.(c) 7
2.(d) 900
3.(b) two
4.(c) 0.0007
5.(d)0.0004
Explanation:
(1) White light after reflection through prism splits into 7 colors.
(2) Arabs and Chinese knew about lenses in about 900 AD
(3) There are Two more colors in the spectrum which cannot be seen with naked eye.
(4) Wavelength of red light is 0.0007mm
(5) Wavelength of violet light is 0.0004mm
If 56.5kJ are needed to raise the temp by 90°C and if the heater is 60% efficient that means that:
60% X y = 56.5kJ
where y is the electrical energy in kJ that the heater will use.
y = 94.2kJ
