Answer:
The energy in object is 3.8 Kilo Joules.
Step-by-step explanation:
We are given the following in the question:
Mass = 20 kg
Height,h = 20 m
g=9.5 m/s^2
Formula:
Potential energy =

Putting value we get,

Thus, the energy in object is 3.8 Kilo Joules.
Answer:
Step-by-step explanation:
Recall that we say that d | a if there exists an integer k for which a = dk. So, let d = gcd(a,b) and let x, y be integers. Let t = ax+by.
We know that
so there exists integers k,m such that a = kd and b = md. Then,
. Recall that since k, x, m, y are integers, then (kx+my) is also an integer. This proves that d | t.
