Answer:
25 degrees
Explanation:
The angle of incidence equals the angle of reflection
If you are talking about Isotopes then I believe it is the amount of atoms that have different amounts of neutrons ,but the same number of protons.
Answer:
Explanation:
If we express all of the cordinates in their rectangular form we get:
A = (1404.77 , 655.06) m
Since we need C to be (0,0) we stablish that:
That way we make an equation system from both X and Y coordinates:
Replacing values:
With this system we can solve for both Db and Dc and get the answers to the question:
Answer:
Option A
Explanation:
An Uninterruptible Power Supply abbreviated as UPS is used in case of the failure of the power mains or the input power in order to ensure uninterrupted power supply.
The Ac voltage is first converted to DC and then again inverted to the AC and is fed to the system.
Thus if the UPS malfunctions then in order to check the output using multimeter we use AC voltage setting because the UPS purely supplies AC power, even if the power is supplied from its internal battery then also it inverts the DC into AC and then supply.
Answer:
<em>The green car had the greatest momentum</em>
Explanation:
<u>Momentum</u>
Momentum can be defined as "mass in motion" and is calculated as the product of the mass of the object by its velocity.
Being v the magnitude of the velocity and m the mass of the object, the momentum is calculated with:
p = mv
The green car had a mass of m1=1200 kg and crossed the finish line at v1=53 m/s. Hence, its momentum was:
p1 = 1200 Kg * 53 m/s = 63600 Kg.m/s
The red car had a mass of m2=1100 kg and crossed the finish line at v2=55 m/s. Hence, its momentum was:
p2 = 1100 Kg * 55 m/s = 60500 Kg.m/s
Since p1 > p2, then the green car had the greatest momentum
