Answer:
JC⁻¹
Explanation:
= mass of water added to calorimeter = 94.8 g
= initial temperature of the water added = 60.4 C
= specific heat of water = 4.184 Jg⁻¹C⁻¹
= mass of water available to calorimeter = 94.8 g
= initial temperature of the water in calorimeter = 22.3 C
= final equilibrium temperature = 35 C
= Heat gained by calorimeter
Using conservation of heat
Heat gained by calorimeter = Heat lost by water added - heat gained by water in calorimeter

Answer:
takes longer than 365 days to orbit the sun
has seasons because of a tilted axis
Note: We see 365 days for a year - from an external point of view, a year would take 366 days to orbit the sun - this is because it takes slightly less than 24 hours from sunrise to sunrise because of the rotation of the earth about the sun (a sidereal year is 366 days as compared to 365 days observed on earth)
Answer:
b. Continental-oceanic
Explanation:
The Earth's crust has been divided into a series of plates. These plates move at a different rate or speed in different directions.
These plates are divided by the boundary between them which are of three types: convergent, transform and divergent.
The convergent boundaries are the one which moves toward each other and the based on the crust they are of three types: continent-continent, ocean-ocean and ocean-continent.
In ocean-continent boundaries, the oceanic plate is denser compared to the continental plate is lighter as a result of which during the process of subduction the oceanic plate sinks beneath the continental plate towards the mantle and melts.
Thus, Option-B is the correct answer.
Answer:
It's D. Momentum,
Explanation:
The Faster An Objects Goes, The Harder It Will Be To Stop.
The force needed to overcome sliding friction is more than the force needed to overcome rolling friction or static or even fluid
