Answer: C)The yellow car was faster. Yellow traveled at a speed of 50 mph while green was traveling at an average of 40 mph.
Explanation:
The speed of each car is defined as:
where d is the distance traveled by the car and t is the time taken.
For the yellow car, d=400 mi and t=8 h, so its speed is
For the green car, d=400 mi and t=10 h, so its speed is
So, the correct choice is
C)The yellow car was faster. Yellow traveled at a speed of 50 mph while green was traveling at an average of 40 mph.
Answer:
True
Explanation:
As of Newton's law, yes. Because when I land my feet on the ground, I apply a force. As per Newton's third law, the ground must apply the same force on me.
If its correct, may I hv brainliest?
Answer:
3 bands
Explanation:
Basically, the Parametric EQ divides the audio spectrum into three bands, allowing you to enhance (or suppress) the level in that range.
The voltage all the way around the loop ... between the terminals of the battery ... is 36 volts total. It looks like 12 of those volts are across one lamp, and 12 of them are across the other lamp. That leaves the last 12 volts unaccounted for, and only one more component in the loop (the resistor), so the remaining 12 volts is across the resistor.
So far, we don't have enough information to calculate any current in the loop, or the power dissipated by any component. To go any farther, we'll need to take your word for it ... the current in the loop is 0.75 Ampere. Fine !
In a resistor . . . Resistance = (voltage) / (current)
Resistance = (12 volts) / (0.75 Amp) = 16 ohms .
Power dissipated by anything = (voltage across it) x (current through it).
Power dissipated by the resistor OR either lamp =
(12 volts) x (0.75 Amp) = 9 watts .
That's not a lot for a light bulb, but it IS for a resistor. That baby has to be physically large (maybe like a lipstick), and cooled ... attached to a heatsink, or air blowing over it, or water flowing over it.
PS: I hope you're right about that 0.75 Amp.
Usually when you travel in a straight line, or one direction. The difference is that if you drive 10 feet in one direction, you are 10 feet from where you started. If you drive 10 feet forward, then 10 feet backward, you are in the same place you started, so you displaced yourself 0 feet. But, you travelled 10 ft + 10 ft, so your distance travelled is 20 ft.
