Answer:
formula: A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15º. The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.
Answer:
C
Explanation:
V=1/p
By means of cross multiplication so by that we will have pv=1 which also implies p1v1=p2v2 coz boyles law states that the volume of a given mass of gas is inversely proportional to pressure provided that the temperature in kelvin remains constant
Vf=vi+at
Vf= (50m/s)+ (5m/s2)(3s)
Vf=65m/s
(a) 1800 N
The equation of the forces along the vertical direction is:
where
is the component of the applied force along the vertical direction
N is the normal force on the sled
mg is the weight of the sled
Substituting:
F = 1210 N
m = 246 kg
We find N:
(b) 0.580
The equation of the forces along the horizontal direction is:
where
is the horizontal component of the push applied by the mule
is the static frictional force
Substituting:
F = 1210 N
N = 1800 N
We find 
, the coefficient of static friction:
(c) 522 N
In this case, the force exerted by the mule is
So now the equation of the forces along the horizontal direction can be written as
where
and 
is the new frictional force, which is different from part (b) (because the value of the force of friction ranges from zero to the maximum value 
, depending on how much force is applied in the opposite direction)
Solving the equation,
Answer:
CGS means Centimeter Gram Second while FPS means Foot Pounds Second
Explanation:
FPS is the standard used to measurement of length, mass and time. The unit of length is foot.
The time is calculated as the unit of seconds. CGS is the measurement of length, mass and time in units of centimeter, gram and second respectively
