I believe Isaac Newtons Law " Gravity ".
Answer:
They are equal
Explanation:
angle of incidence = angle of reflection
Using the formula: ΔY = V₀y * t + (1/2) * ay * t²
Solve for time and get: 1.968s
Then use: v = d/t in the x-direction and get: d = 3.936
Answer:
C 0.85 j/g*k
Explanation:
The specific heat capacity of a material is given by:
where
Q is the amount of heat supplied to the object
m is the mass of the object
is the increase in temperature of the object
For the object in this problem, we have
m = 117 g is the mass
Q = 1200 J is the heat supplied
is the increase in temperature
Substituting into the formula, we find the specific heat:
