The period of a mass-spring system is:
T = 2π
T = period, m = mass, k = spring constant
Given values:
T = 8π s
k = 2 N/m
Plug in and solve for m:
8π = 2π
= 4
m/2 = 16
m = 32 kg
Choice A
Answer:
Explanation:
Work is equal to the product of force and distance.
We are solving for the distance, d. We know the force is 596.82 Newtons and the work is 35,674.7 Joules.
- If we convert the units for Joules, the problem will be simpler later.
- 1 Joule is equal to 1 Newton meter.
- The work done by the runner, 35,674.7 J, equals 35,674.7 N*m
Substitute the values into the formula.
We want to solve for the distance, so we must isolate d on one side of the equation.
d is being multiplied by 596.82 Newtons. The inverse of multiplication is division. Divide both sides of the equation by 596.82 N
The Newtons will cancel, hence the prior unit conversion.
Let's round to the nearest hundredth, so the answer is concise. The 4 in the thousandth place tells us to leave the 7 in the hundredth place.
The distance covered during the portion of the race is about <u>59.77 meters.</u>
Explanation:
Another name of covalent bonds is molecular bonds. Covalent compounds are formed by covalent bonds. The bonds in which atoms share one of more valance electrons are termed as covalent bonds. These types of bonds are in Liquid or gaseous State.
For example, methane is a covalent compound that is formed by the sharing of electrons between carbon and hydrogen atoms. Hence, Covalent compounds are usually described as the sharing of electrons between carbon atoms
A pedestal rock, also known as a rock pedestal or mushroom rock, is not a true balancing rock, but is a single continuous rock form with a very small base leading up to a much larger crown. Some of these formations are called balancing rocks because of their appearance. The undercut base was attributed for many years to simple wind abrasion, but is now believed to result from a combination of wind and enhanced chemical weathering at the base where moisture would be retained longest. Some pedestal rocks sitting on taller spire formations are known as hoodoos. I think this is the answer if I’m wrong I’m very sorry
Answer:
Explanation: The periodic table contains rows and columns. To find how many valence electrons are in an element, simply locate the column number that it is in, and that determines the number of valence electrons in an element. This rule works only for elements excluding the transition metals
