Answer:
Part a)
Part b)
Explanation:
Since the ball and rod is an isolated system and there is no external force on it so by momentum conservation we will have
here we also use angular momentum conservation
so we have
also we know that the collision is elastic collision so we have
so we have
also we know
also we know
so we have
now we have
Part b)
Now we know that speed of the ball after collision is given as
so it is given as
Answer:
A model rocket is launched with an initial upward velocity of 215 ft/s.
Explanation:
Answer:
m = 62.14 g
Explanation:
Energy used to melt the ice is the energy released by the condensation of the water forms on the glass
so here we have
energy for the condensation of water is given as
let mass of water condensed = m
now the energy of vaporization is given as
here we know that
Now we have
Answer:
Explanation:
The climate of any particular place is influenced by a host of interacting factors.
The factor that influence climate are
1. latitude
2. elevation,
3. nearby water
4. ocean currents
5. topography
6. vegetation
7. prevailing winds.
The primary cause of climate change is the burning of fossil fuels, such as oil and coal, which emits greenhouse gases into the atmosphere—primarily carbon dioxide. Other human activities, such as agriculture and deforestation, also contribute to the proliferation of greenhouse gases that cause climate change.
