Which symbol represents a type of electromagnetic radiation released during radioactive decay?

Lena [83]

The correct option is (D) Gamma ( $_0^0\gamma$ )

Explanation:
Now this question is a tricky one because all of these options are somehow involved in radioactive decay; however, in this case the SYMBOL is required NOT the elements. There are three symbols involved in radioactive decay, which are:
1. α for alpha decay
2. β for beta decay
3. γ for gamma decay

In the options only one symbol is present which is gamma. Hence option (D) Gamma ( $_0^0\gamma$ ) is the correct answer.

Tanzania [10]

The answer is C. An object that appears a certain color reflects the light frequency that corresponds to that color, and it absorbs all the other frequencies in the visible light spectrum. An orange absorbs all of the frequencies but orange. A BLUE TEXTBOOK ABSORBS all of the frequencies INCLUDING GREEN except for BLUE.

A baseball pitcher throws the ball in a motion where there is rotation of the forearm about the elbow joint as well as other mov

Inessa [10]

Answer:

K = ½ kg m2 / s2

Explanation:

The kinetic energy rotation is given by the expression

K = ½ I w²

Where I is the moment of inertia and w is the angular velocity.

We have a relationship between linear and angular velocity

v = w r

Where r the distance from the point of rotation, in this case it is the point or where the ball is, so the linear velocity is the same as the ball.

w = v / r

We replace

K = ½ I (v / r)²

Let's calculate

K = ½ kg m2 )(m/s )/ m) 2

K = ½ kg m2 / s2
