The last option would be I think
Many of today’s mathematicians use computers to test cases that are either too time-consuming or involve too many variables to test manually, allowing the exploration of theoretical issues that were impossible to test a generation ago.
Answer: Option A
<u>Explanation:</u>
One of the most useful inventions in scientific world are the computers. We can use different programming language and create programs in them. These programs help other to solve difficult problems. Most of the theoretical problems in science can be solved by using these programming features in computer within a specific time limit.
Otherwise, earlier mathematician used to take months to solve a complex mathematical problem manually, but now with the inclusion of computers, the mathematician can solve the problems containing more number of variables or other theoretical issues.
Answer:
El observador verá correr al perro sobre la cubierta del barco a una velocidad de 40 kilómetros por hora.
Explanation:
Para determinar la velocidad del perro con respecto al observador sentado desde la playa a través del concepto de velocidad relativa, descrito en la siguiente fórmula:
(1)
Donde:
- Velocidad del perro relativo al barco, en kilómetros por hora.
- Velocidad del perro con respecto al observador, en kilómetros por hora.
- Velocidad del barco con respecto al observador, en kilómetros por hora.
Si sabemos que 
y 
, entonces la velocidad del perro con respecto al observador es:
El observador verá correr al perro sobre la cubierta del barco a una velocidad de 40 kilómetros por hora.
Answer:
Atomic number of the daughter isotope = (Atomic number of the parent isotope) - 4
Explanation:
An alpha particle has atomic number of 2 and a mass number of 4
Losing two alpha particles would lead to a reduction of 4 in atomic number and 8 in mass number for the radioactive isotope, to give the stable daughter isotope.
The answer is 6.no got it right
