Radiation transfers energy by moving matter. Please select the best answer from the choices provideda. True
b. False

Answers

Answer 1

Answer: The answer is b. False because radiation transfers energy by the propagation of waves within the electromagnetic spectrum and the travel of photons. Therefore, no matter is moved within this process.

Answer 2

Answer:

False

The period of a wave is found to be 50 seconds. What is the frequency of the wave?

Answers

Frequency is the inverse of the time period. The frequency of the wave will be 0.02.

What is the frequency?

Frequency is defined as the number of cycles per second. The time to make one complete cycle is frequency.

Frequency = 1 / period

F= 1 / T

F=1/50 sec

F=0.02 Hz.

Hence, the frequency of the wave will be 0.02.

To learn more about frequency refer to:

If you remember this one rule, then you can always convert
in either direction between frequency and period.

   (Frequency) times (Period) = 1 .

So Frequency = 1 / period

   = 1 / (50 seconds)

   = (1/50) per second

   = 0.02 per second

   = 0.02 Hertz

Two objects are dropped from rest from the same height. Object A falls through a distance during a time t, and object B falls through a distance during a time 2t. If air resistance is negligible, what is the relationship between A and B?

Answers

Answer:

Distance covered by B is 4 times distance covered by A

Explanation:

For an object in free fall starting from rest, the distance covered by the object in a time t is

$s=(1)/(2)gt^2$

where

s is the distance covered

g is the acceleration due to gravity

t is the time elapsed

In this problem:

- Object A falls through a distance $s_A$ during a time t, so the distance covered by object A is

$s_A=(1)/(2)gt^2$

- Object B falls through a distance $s_B$ during a time 2t, so the distance covered by object B is

$s_B=(1)/(2)g(2t)^2 = 4((1)/(2)gt^2)=4s_A$

So, the distance covered by object B is 4 times the distance covered by object A.

An explosion occurs 340 km away. Given that sound travels at 340 m/s, the time the sound takes to reach you is a. 1 s.
b. 10 s.
c. 100 s.
d. 200 s.
e. more than 200 s.

Answers

(340,000 meters) / (340 meters/sec) = 1,000 seconds

That's more than 200 sec.

first convert 340km into 340,000m, and 340000/340=1000. So the answer is e.
