8 0

Answer:

Explanation:

If we let our reference frame travel at 30 m/s with the constant speed car, The accelerating car increases its velocity by 10 m/s in 3 seconds.

The average velocity of the accelerating car is (0 + 10) / 2 = 5 m/s

It will advance its position 5 m/s(3 s) = 15 m in the accelerating period.

It takes 5 + 3 = 8 m for the two cars to become side by side.

It would take another 5 + 3 = 8 m for the accelerating car to leave a gap of 3 m between.

The car requires 8 + 8 = 16 m to pass the other safely but the acceleration period only gets him to  15 m.

So despite your saying this is not a YES / NO question, the answer is NO the  acceleration is too low or not long enough to meet the required clearances.

Input needed is 10000 J/s / 0.30 = 333333 = J/s

three hours requires 333333(3)(3600) = 360 MJ of energy

360 MJ / 34 MJ/liter = 10.6 liters.

What voltage would be measured across the 15 ohm resistor?
Alona [7]

Answer: That depends on what other components are in the same circuit

along with the 15-ohm resistor.

If there's nothing else, and the battery is connected across the 15-ohm

resistor, then when you measure the voltage across the 15-ohm resistor,

your voltmeter is also connected straight across the battery, and you read

10 volts.

The speed of light ________ when light goes through glass.
Gala2k [10]
What happens when the light hits the glass depends on what it was in before it hit the glass.

WHILE it's in the glass, the speed of light doesn't change.

The left fielder throws the baseball home from 60 m away. The ball's horizontal velocity is 30 m/s, and its vertical velocity is
Vikentia [17]

Answer:

The base runner

Explanation:

To know the correct answer to the question, we shall determine the time taken for the baseball and the base runner to get to the home plate. This is illustrated below:

For the baseball:

Horizontal velocity (u) = 30 m/s

Horizontal distance (s) = 60 m

Time (t) =?

s = ut

60 = 30 × t

Divide both side by 30

t = 60 / 30

t = 2 s

Thus, it will take the baseball 2 s to get to the home plate.

For the base runner:

Horizontal velocity (u) = 5 m/s

Horizontal distance (s) = 5 m

Time (t) =?

s = ut

5 = 5 × t

Divide both side by 5

t = 5 / 5

t = 1 s

Thus, it will take the base runner 1 s to get to the home plate.

SUMMARY:

Time taken for the baseball to get to the home plate = 2 s

Time taken for the base runner to get to the home plate = 1 s

From the calculations made above, we can conclude that the base runner will arrive at the home plate first because it took him 1 s to get to the home plate whereas the baseball took 2 s to get there.
