Answer:
When they collide a earthquake happens
<h3>
Answer:</h3>
Velocity is 1 m/s
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of the kiddy train is 1000 kg
- Radius of the curve is 5.0 m
- Centripetal force is 2000 N
We are required to determine the maximum speed of the train.
- Centripetal force refers to the force experienced by an object in a circular motion towards the center of a circular path.
- It is calculated by the formula;
- , where m is the mass, v is the velocity and r is the radius of the circular path.
- Therefore, using the formula we can find the maximum speed.
Therefore, the maximum speed of the train is 1 m/s
CO will diffuse faster than CO2 because its molar mass is smaller.
The rate of diffusion depends on molecular weight and the least mass will diffuse faster.
C. Life comes from non-living things like the air. Also known as anomalous generation, this idea is based on pre-Aristotelian philosophers that believed that organisms such as mites could be formed from non-living things such as dust. Some of these ideas were adopted into Christianity and the most famous modern tests to test this theory were performed by Pasteur.
