Answer:
Katie Ledecky started the "Dive into STEM Education" because she wanted children to focus on studying the subjects o<u>f Science, Technology, Engineering and Mathematics (STEM).</u>
I know this because Katie stated this when <em>she became a spokesperson during her visit in Las Vegas. </em>She even said<em> "Education has always been front and center in my life."</em>
Explanation:
Katie Ledecky is a popular <em>American competitive swimmer</em> who's supposed to join the upcoming Tokyo Summer Olympics in Japan. Besides preparing for the Olympics, she's also busy persuading young people into online learning, especially when it comes to the "STEM" subjects.
Katie has planned to launch the initiative by partnering with "Panasonic." Besides knowing the value of sports like swimming, she has also known the importance of education. She mentioned that many of her family members are actually in medical fields.
So, this explains the answer.
Per capita GDP of a country is the total quantity of goods produced divided by the number of citizens
A: community service
C: small business group discussions
Answer: υ=5.0x10¹⁴s⁻¹
Explanation: <u>Photoelectric</u> <u>Effect</u> is a fenomenon that occur when incident light on a metal surface causes an electron to be ejected. It is possible to determine the number of eletrons and its kinetic energy by measuring the light's intensity and frequency.
According to Einstein, energy carried by light can be calculated as:
in which
h is Planck's constant, with magnitude h=6.626x10⁻³⁴J.s;
υ is frequency of radiation
Then, frequency of the light is
υ ≈ 5x10¹⁴
<u>The frequency of the light with energy of 3.3x10⁻¹⁹J </u><u>is 5x10¹⁴s⁻¹</u>
