Answer:
The banking angle of the road is 16.38 degrees.
Explanation:
Given:
Radius of the roadway on curve, R = 50 m
velocity of the moving car, V = 12 m/s
The banking angle can be calculated by using the formula below:
If there's no frictional force, then net force is equal to centripetal force.
MgTanΦ = (MV^2)/ R
TanΦ = V^2 / gR
Where;
Φ is the banking angle
g is acceleration due to gravity
TanΦ = (12 x 12) / (9.8 x 50)
TanΦ = 0.2939
Φ = arctan (0.2939)
Φ = 16.38 degrees
Therefore, the banking angle of the road is 16.38 degrees.
Answer:
The correct answer is option C.
Explanation:
The layer below the lithosphere , the upper layer of the mantle of the earth with high heat pressure .It is made up of almost solid rocks but also flows not which indicates that it consist of viscoelastic fluid of molten rocks.This is because in some regions there can be presence of molten rocks.
Answer:
10 million joules or 10,000 KJ
Explanation:
Work= Force x Displacement
convert 5km into meters -5km=5000m
W= 2000N x 5000m
w=10,000,000 Joules
or 10,000KJ
The Answer Is B (: because if it was closed no light could get throw and its not d because air doesnt circulate throw water xD HOPE THIS HELPS ANSWER IS REALLY B ♥
Answer:
<em>The best explanation is that the first person is grounded to the earth, and his/her body either draws up negative charges from the earth, or tend to conducts negative charges to the earth, depending on the charge on the balloon.</em>
Explanation:
The earth is an infinite store for charges. In the first case where the second person brings a negatively charged balloon towards the first person, the negative charges on the balloon induces the first person's body to tend to attract the negative charges on the balloon through the first person's body to the positive charges within the earth. In the second case when again a positively charged balloon is brought near the first person's hair, the positive charges on the balloon induce the first person's body into drawing up negative charges from within the earth. This charges, and their opposite induced charges, create an attractive force between the hair strands and the balloons.
