Answer:
Both distances are in the scientific notation:
Earth - Sun = 9.3 * 10^7 miles
Saturn - Sun = 8.87 * 10^8 miles
8.87 * 10^8 - 9.3 * 10^7 =
= 88.7 *10^7 - 9.3 * 10^7 =
= 79.4 * 10^7 = 7.94 * 10 ^8 = 794,000,000 miles
Answer: Saturn is 7.94 * 10^8 miles farther from Sun than Earth is.
The ratio of output power to input power for a machine is called the machine's efficiency. It doesn't have to be expressed in percent.
Right before it breaks of, because all the other options are examples of Kinetic energy while the A. answer is the only one describing potential energy.
Answer:
35.42kg m^2 s−1
Explanation:
Step one:
the expression for angular momentum is given as
m = mass = 1.8kg
v = velocity = 12.3m/s
r = radius= 1.6m,
Required
L = angular momentum
Step two:
substitute into the expression
L=1.8*12.3*1.6
L=35.42kg m^2 s−1
