Answer:
it helps create products like heat and light and the electric charge is a scaler quantity. there's also voltage and frequency.
Explanation:
Answer:
a = 1.34 m/s²
Explanation:
given,
mass of the attendant(M) = 75 Kg
mass of cart (m)= 27 Kg
Backward force exerted on floor (F)= 155 N
frictional force on the cart (f)= 18 N
acceleration
F_{net} = F - frictional force
F_{net} = 155 N - 18 N
F_{net} = 137 N
now,
a = 1.34 m/s²
the acceleration produced when flight attendant is equal to a = 1.34 m/s²
Answer:
0.38296 m
1.02132 rad
Explanation:
Angular frequency is given by
Displacement is given by
Velocity is given by
The phase angle is 1.02132 rad
The amplitude is 0.38296 m
The equation is given by
The equation is
Gravity changes as the altitude change.<span> The gravitational force is proportional to 1/R2, where R is the distance from the center of the Earth the radius of earth where gravity is 9.8 m/s^2 is 6400 km this will serve as the zero mark.
g1/(g2) = R2^2/(R1)^2
so we set the constant values to R1 and the unknown distance as x
(9.8)/(8.80) = (6400-x)2/(6400)^2
solving for x we will get
x = 345.85 km above the earths surface
