By using an electric field, it is feasible to differentiate between these different forms of radiation.
<h3>What is a radioactive source?</h3>
A source that emits radiation like gamma, beta, and alpha rays is said to be radioactive. Using an electric field, we can discriminate between these different forms of radiation.
The field does not deflate the gamma rays, but it does deflate the alpha and beta rays, with the alpha being deflated to the field's negative portion and the beta to its positive part.
Hence, by using an electric field, it is feasible to differentiate between these different forms of radiation.

In the bedroom the soundwaves will travel because there is no force to suppress the sound other than the walls. While in a pool the water molecules will suppress the sound wave. Like it's different when you beat i under a blanket rather than outside.
Hope this helps!
Answer:
The average speed is 3.5 mi/h
Explanation:
Average speed is given by
If the total distance covered is mi,
Then mi was covered while hiking and
mi was covered while running.
Now, we will find the time taken while hiking and the time taken while running
- For the time taken while hiking
Speed = 2.9 mi/h
Distance = mi
From,
Time = h
Time taken while hiking is 0.2299 h
- For the time taken while running
Speed = 5.6 mi/h
Distance = mi
Time = h
Now, for the average speed
Total distance = mi + mi = mi
Total time = + = h
∴
Average speed = 3.4552 mi/h
Average speed ≅ 3.5 mi/h
Answer:
<em>Si hay rozamiento y el valor de la fuerza de roce es 10 N</em>
Explanation:
<u>Fuerza Neta</u>
La fuerza neta sobre un cuerpo es la suma vectorial de todas las fuerzas actuantes sobre el mismo.
Si conocemos el módulo de la fuerza neta F y la masa m del cuerpo, aplicamos la segunda ley de Newton para relacionarlas con la aceleración a:
Tenemos los datos cinemáticos de la situación, según la cual el cuerpo adquiere una velocidad (desde el reposo) de 4 m/s en 5 s.
Utilizamos la fórmula:
Y despejamos la aceleración:
Podemos calcular la aceleración real que el cuerpo adquiere, producto de una fuerza efectiva igual a:
Si se está aplicando una fuerza de y solo 20 N producen movimiento, entonces se está perdiendo en rozamiento una fuerza:
Si hay rozamiento y el valor de la fuerza de roce es 10 N
Answer:
2.82 x 10⁷J
Explanation:
Given parameters:
Power rating of the motor = 1.5hp
Time taken = 7hrs
Unknown:
Amount of electrical energy consumed = ?
Solution:
To solve this problem, we need to convert first to standard unit.
1 hp = 746 Watts
1.5hp = 746 x 1.5 = 1119Watts
Also;
7hrs to Seconds;
1 hr = 3600s
7hr = 7 x 3600 = 25200s
So;
Electrical energy = Power x time = 1119 x 25200 = 2.82 x 10⁷J
