Explanation:
Given
Diameter 
radius 
From diagram, at top point
If Normal force is equal to Gravitational force
where N=normal reaction
m=mass of car
Normal reaction will provide centripetal force
thus
Answer:
754.6 m
Explanation:
The GPE (Gravitational potential energy) of an object with respect to the ground is given by
where
m is the mass of the object
g = 9.8 m/s^2 is the acceleration due to gravity
h is the heigth above the ground
Here we have
m = 12,400.05 kg is the mass
GPE = 91,700,000.00J is the GPE
Solving the formula for h, we find the heigth:
Answer:
Sound quality
Explanation:
Loudness refers to the property of sound that depends on the amplitude of the sound wave while pitch is the property of sound that depends on the frequency of the sound wave.
Now, when sounds have the same pitch and loudness, it means they possess the same natural frequency and also, they will have similar resonance and standing waves. Despite all these similarities, the quality of these sounds will tend to vary from one to another.
Answer:
Explanation:
1) J = P = 100 g
Mass does not change with location.
2) 10 m/s
v² = u² + 2as
0² = u² + 2(-10)(5)
3) N(ewton)
Answer:
correct answer is iron
Explanation:
solution
as Iron is only formed in the cores of the star that is more massive than the sun because it takes very much energy as gravitational force push inward on the star
and the sun can form the helium and carbon and the oxygen and also other elements
but not the iron or any iron group element
so correct answer is iron
