Newton's second law states that F= m xa (Force is mass times acceleration). Which example would have the GREATEST
ludmilkaskok [199]

Newton's second law states that F=m \times a (Force is mass times acceleration). Out of the given options, “a 10 kg ball thrown with a 50 Newton force”, an example have the greatest acceleration.

<u>Explanation: </u>

To do the calculation, we already have the formula given derived from Newton’s second law of motion. To know the acceleration, we can simply modify the formula as,

                  \text { Force }=\text { mass } \times \text { acceleration }

                  \text {acceleration}=\frac{\text {Force}}{\text {mass}}

For the 10kg ball threw in 50N, we have mass = 10 kg and Force = 50 N

Acceleration =  \frac{50}{10}=5 \mathrm{m} / \mathrm{s}^{2}

Similarly for 1 kg ball threw in 0.5N, substituting the values, we get ,

Acceleration =  \frac{0.5}{1} = 0.5 \mathrm{m} / \mathrm{s}^{2}

For launching 50kg student by catapult of 100N,

acceleration = \frac{100}{50}=2 m / s^{2}

For accelerating 500 kg car in 1000N engine,

acceleration = \frac{1000}{500} = 2 m / s^{2}

If the radius of a star increases by a factor of 6 the surface area of the star increases how many times?
Dennis_Churaev [7]

Answer:

When radius of star increase by 6 factor then area of star will increase by a factor of 36.

Explanation:

As we know that

Area of star A given as

A=4\pi R^2

Where R is the radius of star.

Area of star when radius become 6 times

A'=4\pi (6R)^2

A'=4\pi \times 36\times R^2

So

A'=36A

We can say that when radius of star increase by 6 factor then area of star will increase by a factor of 36.

iren2701 [21]
Depending on what way you are trying to use it electrons connect to almost anything just like little balls of magnetics think of it that way. of it being able to just force and charge into any thing.
