Applying the concept of scalar product. We know that vectors must be multiplied in their respective corresponding component and then add the magnitude of said multiplications. That is, those corresponding to the 
component are multiplied with each other, then those corresponding to the 
component and so on. Finally said product is added.
The scalar product between the two vectors would be:
Therefore the scalar product between this two vectors is 5.74
Bottom rail is called the "stuff" that holds a car window in place.
Use the Second Law of Newton, which states that Net Force = mass times acceleration
F = m * a
F = 50 kg * 1.5 m/s^2 = 75 N
Answer: option C
<h2>
Cost savings in using the fluorescent bulb is 3.81 cents</h2>
Explanation:
A 100 watt incandescent light bulb is operated for 7 hours.
Energy used by 100 watt incandescent light bulb = Power x Time
Energy used by 100 watt incandescent light bulb = 100 x 7 = 700 Wh
Energy used by 100 watt incandescent light bulb = 0.7 kWh
A 32 watt fluorescent light bulb is operated for 7 hours.
Energy used by 32 watt fluorescent light bulb = Power x Time
Energy used by 32 watt fluorescent light bulb = 32 x 7 = 224 Wh
Energy used by 32 watt fluorescent light bulb = 0.224 kWh
Cost of electricity per kWh = 8 cents
Cost of electricity by 100 watt incandescent light bulb = 0.7 x 8 = 5.6 cents
Cost of electricity by 32 watt fluorescent light bulb = 0.224 x 8 = 1.792 cents
Difference in costs = 5.6 - 1.792 = 3.808 cents
Cost savings in using the fluorescent bulb is 3.81 cents
Answer:The “event horizon” of a black hole is the point of no return. That is, it comprises the last events in the spacetime around the singularity at which a light signal can still escape to the external universe. For a standard (uncharged, non-rotating) black hole, the event horizon lies at the Schwarzschild radius.
