Answer:
The object has 1250 Joules of Kinetic Energy.
Explanation:
Kinetic Energy =
mass*velocity²
KE =
mv²
KE =
(100kg)(5m/s)²
KE =
(100kg)(25m/s²)
KE = 1250
KE = 1250J

Since we are finding the new volume

From the question we have

We have the final answer as
<h3>0.89 L</h3>
Hope this helps you
The correct answer is the Black Market.
The Black Market refers to the informal (and sometimes formal) system of trading of illegal goods by merchants and dealers of products such a weapons, drugs, and good that have been banned by countries. This can also apply to informal marketplaces in countries with sanctions placed upon them get goods that formal treaties are blocking the people from accessing.
Answer:
Two estimates
Explanation:
There are mainly two estimates used in the calculation of depreciation such as the useful life and the salvage value of an asset. The salvage value is defined as the predicted amount that will be obtained by a company from an asset when it is disposed at the end of the useful life of the particular asset. On the other hand, the useful life commonly refers to the estimation of how long the asset is useful for the company. This is different from the lifespan of the asset.
Answer:
Elastic potential energy, E = 3.26 J
Explanation:
It is given that,
Force constant of the spring, k = 5.2 N/m
Relaxed length of the spring, X = 2.45 m
When the mass is attached to the end of the spring, the vertical length of the spring is, x' = 3.57 m
To find,
The elastic potential energy stored in the spring.
Solution,
The extension in the length of the spring is given by :


x = 1.12 m
The elastic potential energy of the spring is given by :


E = 3.26 J
So, the elastic potential energy stored in the spring is 3.26 joules.
