Luba_88 [7]3 years ago
3 0

Answer:

Three, but see below.

Explanation:

You can be certain of three, but that may not be true at all. The only way to know for certain is to put it into scientific notation.

4.05 * 10^5 would be three, but other answers are possible. For example

4.050 * 10^5 would have 4.

Does the rankine degree represent a larger or smaller temperature unit than the kelvin degree
zvonat [6]
The best and most correct answer among the choices provided by the question is the first choice, larger.

Rankine is Fahrenheit + 460 , while Kelvin is Celsius + 273. We all know that Fahrenheit has larger number compared to kelvin , thus rankine is much larger.

If the earth’s tilt on it axis were to increase by 20 degrees, what would happen to earth?
Triss [41]

An electric motor supplies 2,500 Watts of power in a 220 V circuit. What is the resistance of the motor? Be sure to include the
s344n2d4d5 [400]

Answer:

R = 19.36  ohms

Explanation:

Given that,

The power of an electric motor, P = 2500 Watts

The voltage of the circuit, V = 220 V

We need to find the resistance of the motor. We can find it as follows :

P=\dfrac{V^2}{R}\\\\R=\dfrac{V^2}{P}\\\\R=\dfrac{(220)^2}{2500}\\R=19.36\ \Omega

So, the resistance of the motor is 19.36  ohms.
