Answer:
The movement of Tectonic plates.
Explanation:
Answer:
Explanation:
Let the internal resistance be r .
Since in open circuit the volt is 1.55 V , this will be the source voltage .
Source voltage = 1.55
If external resistance be R .
1.55 / (R + r ) = .500
R + r = 3.1 ohm
So sum of internal resistance and external resistance will be 3.1 ohm.
The Correct Answer is <u>D.Infrared/</u> <em>INFARED has a lower frequency than visible light/</em>
Answer:
P = E / t definition of power is energy / unit time
1 W = 1 Joule / sec definition of 1 Watt of power
E = 2.6E4 J/s * 30 s = 7.8E5 Joules = 780,000 Joules
Answer:
Explanation:
Acceleration can be found by dividing the change in velocity by the time.
(<em>v </em>is the final velocity, <em>u</em> is the initial velocity, <em>t </em>is the time).
The velocity increased from 22 m/s to 236 m/s in 5 seconds. Therefore:
Substitute the values into the formula.
Subtract in the numerator.
Divide.
The acceleration of the object is <u>42.8 meters per square second.</u>
