Average speed is the ratio of total distance moved by Chi in total time interval
So here we will have
Total distance = 100 m + 400 m
Total time taken = 5 min + 15 min = 20 min
now by the formula of average speed we know that
so average speed will be 1.5 km/h
Answer:
They both describe atoms as being made up of positive and negative matter.
Explanation:
In both Bohr's model and Thomson model, the atom consists of positively-charged matter and negatively-charged matter. However, the structure of the atom in the two models is totally different:
- in Thomson's model, the atom consists of a large sphere of uniform positive charge, and electrons (which are negatively charged) are scattered all around inside this sphere
- In Bohr's model, the atom consists of a small, positively charged nucleus, while the electrons (negatively charged) orbit around the nucleus in precise orbits.

Answer:
resultant velocity of boat will be 11.2249 m/sec
Explanation:
We have given speed of boat 
= 10 m /sec
Velocity pf current flow 
= 4 m /sec
Angle at which boat is moving = 60°
We have to find the resultant velocity
We know that resultant velocity is given by 
So resultant velocity of boat will be 11.2249 m/sec
