That's true.
Newton's law of universal gravitation says that the gravitational
force between two objects is
F = G · M₁ · M₂ / D² .
There's no note under the equation that says "only up to
this certain distance, and zero any farther than that".
The equation is true no matter how gigantic the distance
is between the objects.
(A) The impeller blades are worn or slipping on the shaft
Answer:
Add Ff from Fa
Explanation:
Fnet = sum of all force
horizontal net force = Ff + Fa
Answer:
a) , b) , c)
Explanation:
a) Let assume that electric motor is single-phase and operates in DC-mode, so that mechanical power output is:
The current delivered to the motor is:
b) The power delivered to the motor is:
The energy delivered to the motor during 3.80 hours of operation is:
c) The cost to run the motor is:
The car would go from zero to 58.0 mph in 2.6 sec.
Since the force on the car is constant, therefore the acceleration of the car would also be constant.
Now for constant acceleration we can use the equation of motion
Using first equation of motion to calculate the acceleration of the car
v=u+at
29=0+a×1.30 ...... Eq. (1)
Again using the first equation of motion
58=0+a*t ....... Eq. (2)
Dividing eq. (2) with equation 1
t=2×1.3
t=2.6 sec
