Answer:
The pulling force that acts along a stretched flexible connector, such as a rope or cable, is called tension, T. When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.
1.) Ohm's law is understood as I = V/R. Given that resistance is constant, then voltage changes directly proportional to current.
2.) The more current that passes through a lightbulb, the brighter it glows. The higher the current, the higher the power, where power determines the brightness of a bulb.
3.) A bulb has a specific limit to how much power (Watts) it can handle. Going over the limit would cause the bulb to burn out.
4.) When a bulb burns out, no current will be able to pass through the filament.
There are several information's already given in the question. Based on those information's the answer can be easily deduced.
Speed of the truck = 70 kph
= 19.44 m/s
Speed of sound = 343 m/s
Then
Observed frequency = 400 Hz ∗ 343 m/s/<span>19.44m/s + 343 m/<span>s
= 378.54
= 379 Hz</span></span>
The correct answer would be C. three half lives.
Answer:
Yes
Explanation:
Newton's laws states that gravity or force will stop the balls movement. Think of space for a example, if you pushed a soccer ball into space if would float for eternity.
