A beta and gamma source, Co-60, was placed in a chamber which was first lined with paper and then, after, with copper and lead. A Geiger counter was used in both cases to detect the emission of radiation. You expect
es -0)
A)
no emissions to be recorded in either case.
B)
strong emissions to be recorded outside the chamber in both cases.
some emissions when the chamber is lined with paper, but none when lead
Lined,
D)
strong emissions when the chamber is paper lined; faint emissions when
lead lined.

wavelength divides in half and speed stays the same.

so easy. just google the electromagnetic waves and it’ll pop up.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
