I’m pretty sure you times them so 1 with A, 2 with e, 3 with C, and 4 with B
Assuming all the substances are already at the temperature that is their melting point, we only need to worry about the heat required to change state, not the heat required to change temperature.
No calculations necessary for this question - just look at the latent heat of fusion. The higher this value, the more heat required per unit mass of the substance to melt it. Of the four answer options, aluminum has the highest value and therefore will take the most heat to melt the same mass.
Object weight varues on cellestial bodies due to the acceleration due to gravity acting on the body. the acc due to gravuty depend on the mass and radius of the cellestial body. Thus the weight varies on cellestian bodies
I would think <em>B,</em> along the Amazon River. This is because of the warm climate ad lots of rainfall.
Answer:
Explanation:
Mass of the kid 23.7 kg.
We need to find the acceleration of the kid,
We know that, Parallel force acted on the kid at an angle is
F = m × g × sinθ (F = ma)
m × a = m × g × sinθ
Now, substitute the given values in the above formula to find acceleration of the kid,
23.7 × a = 232.26 × 0.733
23.7 × a = 170.24
