150+30x
1700=150+30x
1550=30x
x=1550/30=51
I know its is 3,000 cause its said unit period
Answer:
S = 3.92π
Step-by-step explanation:
The formula for area of a sector is
S = (Ф/360°)πr² where Ф is the angle of the sector in degrees, and r is the radius.
The radius is half of the diameter, so we have 5 = 5.6/2 = 2.8, and Ф = 180°
The area is
S = (180°/360°)π(2.8)²
S = (1/2)π(7.84)
S = 3.92π
For this case, the gravitational force is given by:
F = m * g
Where,
m: mass of the object
g: acceleration due to gravity
Substituting values we have:
F = (100) * (9.8)
F = 980 N
Answer:
The gravitational force that is pulling the object to the center of the Earth is:
F = 980 N
