Answer:
V = 42187 m/s = 42.18 km/s
Explanation:
given data:
mass of sun is
radius of earth orbit is
minimum speed can be determined by using following formula
}
where G is
Plugging all value to get desired value
V = 42187 m/s = 42.18 km/s
Answer:
59.55 cm
Explanation:
Note: A meter stick has a length of 100 cm, and it is balanced at 50 cm.
From the principle of moment,
Sum of clockwise moment = sum of anti clockwise moment
Taking moment about the center
mg(50-x) = m'(y-50)g.................. Equation 1
Where m = first mass, m' = second mass, x = position of the first mass, y = position of the second mass, g = acceleration
make y the subject of the equation
y = (m(50-x)/m')+50.................... Equation 2
y = (0.11(50-17)/0.38)+50
y = (0.11(33)/0.38)+50
y = 9.55+50
y = 59.55 cm

Density = mass / volume so mass = density x volume
2 litres = 2000cm^3
mass = 1.27 x 2000 = 2540g = 2.54 kg
Mercury
Good luck on this!
Have fun
