Answer:
88.14 m/s
Explanation:
From the question given above, the following data were obtained:
Radius (r) = length of blade = 80 m
Revolution (rev) = 1
Time (t) = 5.7 s
Velocity (v) =?
The velocity of the blade can be obtained by using the following formula:
v = (rev × 2πr) / t
NOTE: Pi (π) = 3.14
v = (1 × 2 × 3.14 × 80) / 5.7
v = 502.4 / 5.7
v = 88.14 m/s
Therefore, the velocity of the blade is 88.14 m/s
is our feeling depend or electrostatic force
no our feelings doesn't depends on electrostatic force
Average speed = (total distance covered) / (total time to cover the distance)
= (2,742 km) / (4.33 hours)
= (2,742 / 4.33) km/hr
= 633 km/hr (rounded)
Answer:
Explanation: El músculo esquelético está formado por fibras musculares, rodeadas de una capa de tejido conjuntivo, denominada endomisio. Las fibras se reúnen en fascículos primarios, que también están rodeados por otra capa de tejido conjuntivo, esta vez, más grueso, denominada perimisio.
Answer:
D. location
Explanation:
The gravitational field strength of Earth is determined by the virtue of the location within the Earth's gravitational field.
That's why all objects regardless of their mass, shape, and size free fall towards the Earth with an acceleration equal to the acceleration at that location in the absence of air resistance.
According to the gravitational force between two bodies, the force experienced by one body due to the other is independent of its own mass.
The gravitational force is given by equation
F = GMm/r²
If F is the force acting on the smaller body of mass 'm', then
F = ma
Therefore, the equation becomes,
ma = GMm/r²
a = GM/r²
The value of 'a' changes with respect to the value of 'r' such that if 'r' is the radius of the Earth, then the acceleration at a height 'h' from Earth surface is given by
a = GM/(r+h)²
Here it is clear that the acceleration at any point is only the inherent property of the Earth itself.
The gravitational field strength of Earth is determined by the virtue of the location within the Earth's gravitational field.
