Rain fall which is called run off
Answer:c
Explanation:
The buoyancy force on toy depends upon the volume of toy under pool water.
According to Archimedes principle buoyant force on a floating body depends upon the weight of displaced liquid by object.
Buoyancy force is given by
where 
=density of fluid
V=volume of object under water
g=acceleration due to gravity
Answer:
The total energy in the system remains the same as the decrease in chemical energy equals the increase in thermal and radiant energy
Explanation:
According to the law of conservation of energy, "energy cannot be created nor destroyed, but only transformed".
This means that for an isolated system, the total energy of the system must remain constant.
In this case, the total energy of the system (the battery and the lightbulb) is the sum of 3 components:
- Chemical energy of the battery
- Thermal energy (the heat produced by the light bulb)
- Radiant energy (the light emitted by the bulb)
The sum of these 3 components of energy must be constant.
At the beginning, all the energy is stored as chemical energy inside the battery. Later, this energy is converted into electrical energy first (when the current starts circulating through the circuit), and finally, this energy is entirely converted into thermal energy and radiant energy as heat and light emitted by the bulb.
Answer:
Total distance she cover = 14km
Magnitude of displacement = 10 km
Direction of her displacement is East-south
Explanation:
Given:
Distance travel (East) = 3 km
Distance travel to south = 8 km
Distance travel (East) = 3 km
Computation:
Total distance she cover = 3km+8km+3km
Total distance she cover = 14km
Magnitude of displacement = 
Magnitude of displacement = 10 km
Direction of her displacement is East-south
