Average speed = (distance covered) / (time to cover the distance)
Average speed = (14 km) / (249 min)
Average speed = (14/249) (km/min)
Average speed = (14/249) (km/min) x (60 min/hr)
Average speed = (14 x 60 / 249) km/hr
<em>Average speed = 3.37 km/hr</em>
One path because in a series circuit it is only one path while in a parallel circuit you have 2 or more. Our houses use parallel so that is why you can turn off one light and the rest would stay on.
Answer:
Reading a Graduated Cylinder
Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid. The liquid will tend to curve downward. This curve is called the meniscus. Always read the measurement at the bottom of the meniscus.....
hope it helps....

Answer:</h3>
49500 kgm/s
<h3>
Explanation:</h3>
Data given;
- First car; Mass = 1100 kg
- Velocity = 30 m/s
- Second car; mass = 1100 kg
- Velocity = 15 m/s
We are required to calculate the total momentum of the system.
- We need to know that momentum is calculated by multiplying the velocity of a body by its mass.
- Therefore;
Momentum of the first car = 1100 kg × 30 m/s
= 33,000 kgm/s
Momentum of the second car = 1100 kg × 15 m/s
= 16,500 kgm/s
Therefore;
Total momentum = 33,000 kgm/s + 16,500 kgm/s
= 49500 kgm/s
Thus, the total momentum of the system is 49500 kgm/s
The answer is D because theres nothing stopping that person from falling
