3. A satellite orbiting the Earth has an orbital radius of 2.50x10 m. Calculate its speed in orbit. Given:
r=
M=5.97 x 10^24 kg (planet Earth's mass)
G=6.67 x (10^- 11) N. m/(kg 2)
Unknown:
v=?
Equation:
v=square root (GM/T)

(IT IS NOT A Multiple choice question)

To find the mass defect for uranium-238 several calculations must be made. which is the calculation that should be made first? assume atomic number for uranium-238 is 92. a. 92(1.0073) x 92(1.0087) = b. 92(1.0073) x 146(1.0087) = c. 146(1.0073) x 238(1.0087) = d. 238(1.0073) x 238(1.0087) =
