Answer:
Explanation:
specific heat of granite S = 800 J /g°C
increase in temperature = 15.5 °C .
mass = m ( let )
Heat needed to raise temp = mass x specific heat x rise in temperature
150,000 = m x 800 x 15.5
m = 12.096 g .
Weight, in physics elaborately is a type of force which pertains to the gravitational attraction of the earth and the mass of the object.
Hence, the formula for weight is mass x gravity.
Mathematically - w = m x g
Solution:
Mass = 8 kg
Gravity = 10 m/s2
Weight = 10 x 8
Weight = 80 kg*m/s2 or 80N
Therefore the weight of the 8 kg object is 80 newton.
Answer:
Increasing population
Explanation:
As we can see that the death rate is decreasing while at the same time the birth rate is increasing due to which it increased the population that directly impact the planet so great
Day by day the population of the villages, cities, states, the country is increasing which would create a direct human impact on the planet
Therefore the increasing population is the one and single most important reason
