The centripetal force is calculated using the following rule:
F = (m * v^2) / r where
F is the centripetal force = 6000 newtons
m is the mass of the object = 1200 kg
v is the uniform velocity of the object = 20 m/sec
r is the radius of the circular curve that we want to calculate
Substitute with these givens in the above equation to get the radius as follows:
6000 = (1200 * (20)^2) / r
6000 = 480000 r
r = 80 meters
Answer:
Explanation:
a )
Force at the surface = FR
Value of g at height h = g( 1 - 2 h / R )
force at height h = F_R ( 1 - 2 h / R)
F_R / 2 = F_R ( 1 - 2 h / R)
= F_R - 2 F_R xh / R
F_R / 2 = 2 F_R x h / R
1 / 2 = 2h / R
4h = R
h = R / 4 . Ans
b )
Value of g at depth d = g( 1 - d / R )
force at depth d = F_R ( 1 - d / R)
F_R / 2 = F_R ( 1 - d / R)
= F_R - F_R xd / R
F_R / 2 = F_R x d / R
1 / 2 = d / R
2d = R
d = R / 2
To solve this problem it is necessary to apply the concepts related to Torque and Inertia.
Torque is defined as the force applied to a given distance radius, that is
Replacing with our vales we have that
On the other hand the definition of Inertia defines us that it is inversely proportional to angular acceleration and proportional to torque, that is to say
Pi is not involved in the calculation of a triangle's area.
If you're using 'R' to represent 'Radius', a triangle doesn't
have one of those either.
So neither pi nor R is involved in the area of a triangle.
Answer:
A producer needs the sun to make its own food, because producers use photosynthesis. In photosynthesis you use the sun to turn the air people breathe out and water into glucose and oxygen.
