An object that travels around another object in space, is called a Satellite.
Answer:
9.43*10^3 year
Explanation:
For this question, we ought to remember, or know that the half life of carbon 14 is 5730, and that would be vital in completing the calculation
To start with, we use the formula
t(half) = In 2/k,
if we make k the subject of formula, we have
k = in 2/t(half), now we substitute for the values
k = in 2 / 5730
k = 1.21*10^-4 yr^-1
In(A/A•) = -kt, on rearranging, we find out that
t = -1/k * In(A/A•)
The next step is to substitite the values for each into the equation, giving us
t = -1/1.21*10^-4 * In(5.4/15.3)
t = -1/1.21*10^-4 * -1.1041
t = 0.943*10^4 year
Answer:
Distance that sled move while slowing down= 195.65m
Explanation:
Distance traveled by sled after slowing down=S
acceleration at the start= -2.3 m/s2
initial speed u=30m/s
final speed=v
By using the equation
Final speed is zero.
Therefore;
