How much force would you need to push a 5kg dog on a skateboard to an acceleration of 3m / s2 ?
LekaFEV [45]

Answer:

The force you need to apply would be 15 N.

Explanation:

To find the Force you need to apply, you have to use Newton´s second law     (F = m x a).

F = m x a ⇒ F = 5 kg x 3 m/s²⇒ F = 15 N.

The force would be 15 N.

Carbon-14 undergoes radioactive decay in the reaction above. Determine the type of radiation emitted in this reaction and descri
Drupady [299]

<u>Answer:</u> The beta-particle is being released in the reaction and the nucleus is changing from to nitrogen.

<u>Explanation:</u>

Carbon-14 undergoes a radioactive decay by the process of beta-minus decay.

In beta-minus decay, a neutron gets converted to a proton and an electron.

The equation for the beta-minus decay of carbon-14 follows the reaction:

_6^{14}\textrm{C}\rightarrow _7^{14}\textrm{N}+_{-1}^0\beta

In this reaction beta-particle is being released carrying -1 charge. Another name for this particle is known as electron.

In this decay process, the nucleus is changing from carbon to nitrogen. The property of the nucleus is changing completely as number of protons is getting increased.

A student collects 25 mL of gas at 0.98 bar. What volume would this gas occupy at 1.013 bar? * 3 points 25.8 mL 24.2 mL .09 mL 3
trasher [3.6K]

Answer:

24.2 mL.

Explanation:

<em>Assuming constant temperature</em>, we can solve this problem using <em>Boyle's law</em>, which states:

  • P₁V₁=P₂V₂

Where:

  • P₁ = 0.98 bar
  • V₁ = 25 mL
  • P₂ = 1.013 bar
  • V₂ = ?

We <u>input the data</u>:

  • 0.98 bar * 25 mL = 1.013 bar * V₂

And <u>solve for V₂</u>:

  • V₂ = 24.18 mL

The closest option is the second one: 24.2 mL.
