Explanation:
Answer:
ALMA is a trans-formative radio telescope that can study cosmic light that straddles the boundary between radio and infrared. Most objects in the Universe emit this kind of energy, so the ability to detect it has been a driver for astronomers for decades.
Explanation:
Physical science explains the physical world and not supernatural events and an idea is considered true by science if it can be observed, explained and reproduced by others.
<h3>What is physical science?</h3>
Physical science is a systematic study of the of the physical world and phenomena based on observation and experiments.
The scientific method involves:
- observation and questions
- hypothesis
- experiments
- results and further experiments
- theories and laws
Science explains the physical world and not supernatural events.
Science studies physical phenomena such as the stars, the planets, living things, etc.
Science do not study about angels or demons or supernatural events.
An idea is considered true by science if it can be observed, explained and reproduced by others.

Explanation:
U alr finished it so there's no point
To solve this problem we will apply the concepts related to the Doppler effect. This is understood as the change in apparent frequency of a wave produced by the relative movement of the source with respect to its observer. Mathematically this is given as,
Here,
v = Speed of the waves in the middle
= Speed of the receiver in relation to the medium (Positive if the receiver is moving towards the transmitter or vice versa)
= Speed of the source with respect to the medium (Positive if the source moves away from the receiver or vice versa)
Our values are given as,
Replacing,
Solving for the velocity of the source,
Therefore the speed of the other train is 26.1m/s
