Gravitational potential energy = mgh or mass times acceleration due to gravity times the height
Here the mass is 0.25kg, the height is 10m, and gravity is 9.8m/s^2 so...
GPE = (0.25)(10)(9.8)
GPE = 24.5 J
It doesn't mean that the climate is changing, it is probably just the morning dew.
The answer is C. <span>Light travels at different speeds in water and in glass.</span>
Answer:
I) 420000J
ii)
Explanation:
(I) so you can use the formula for quantity of heat then substitute the values given
formula-Q=mc∆9
Thermometer there's others you can use but i know that's one of them
