Answer:

The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.

Explanation:

Answer:

The period of the resulting oscillatory motion is 0.20 s.

Explanation:

Given that,

Spring constant k= 3\ N/m^2

We need to calculate the time period

The object is at rest and has no elastic potential but it does has gravitational potential.

If the object falls then the the gravitational potential change in to the elastic potential.

So,

mgh=\dfrac{1}{2}kh^2

m=\dfrac{1}{2}\times\dfrac{kh}{g}

Where,h = distance

k = spring constant

Put the value into the formula

m=\dfrac{1\times3\times3.42\times10^{-2}}{2\times9.8}

m=5.235\times10^{-3}\ kg

Using formula of time period

T=\dfrac{1}{2\pi}\times\sqrt{\dfrac{m}{k}}

Put the value into the formula

T=\dfrac{1}{2\pi}\times\sqrt{\dfrac{5.235\times10^{-2}}{3}}

T=0.20\ sec

Hence, The period of the resulting oscillatory motion is 0.20 s.

1. List one way mitosis and meiosis are the same and one way they are different.
kolbaska11 [484]
1. They both are same in the process, I mean they both are types of cell division they both form and give rise to new cells from the existing ones
difference would be in their division a mitotic cell gives rise to 2 cells where as a meiotic cell gives rise to 4.
2. the advantage of sexual reproduction is that , it produces genetic variation, disadvantage is it's a very slow process and takes lot of time
3. the advantage is that ,it's a very rapid process as it doesn't involve complex interactions. of genes and chromosomal recombination, the disadvantage would be is that they don't produce variation which can have adverse affect on their survival, even due to slightest change in the environment
4. Undergoing both the type of cell division is good as in human mitotic division is meant for growth and development whereas meiotic divisions are necessary and important for gametes formation and for raising new generation

A regular atom has a net charge of _____
Doss [256]
An atom is defined as having the same number of electrons (negative charge), protons (positive charge) and neutrons (no charge). This means that it will have the same amount of negative and positive charge, giving it a net zero charge. On the other hand, an ion has different amount of electrons and protons.
