Answer:

alpha

Explanation:

As unstable nuclei breaks into some other nuclei in order to attain stability. We will have three type of nuclei decay as following

1). Alpha Decay = it is positively charged high speed helium nuclei which will have energy in form of kinetic energy. Since these are heavy nuclei so penetration power of them is small and they are positively charged

2) Beta Decay = In this type of decay we will have negatively charged electrons released by the unstable nuclei and they move with high energy as they are of lesser mass. Penetration power of beta is more than alpha

3) Gamma Decay = It is neutral and massless photons which contains high energy. Penetration power of gamma is highest among all.

So here as we know that radiation particle is deflected towards negative terminal so it must be a positive particle so here correct answer must be

alpha

The correct answer would be the first option. Based on the given description above, the type of radiation that is being emitted is ALPHA RADIATION. Alpha radiation is the type of radiation having the lowest penetrative power. Take note that <span>Gamma is stronger than Beta is stronger than Alpha. Hope this answer helps. Have a great day!</span>

What body systems help these cells get the energy they need?
MakcuM [25]

The body systems that help cells get the energy they need are the digestive system and circulatory system. The first system is the digestive system because when you eat food, your body breaks it down using the stomach and other different parts of the digestive system.  The next one is the circulatory system because your blood carries the nutrients you acquired from food you digested to the cells throughout your body.

Student 1 lifts a box with a force of 500 N and sets it on a tabletop 1.2 m high. Student 2 pushes an identical box up a 5 m ram
Troyanec [42]

The student who did the most work is student 2 with 2500 Joules.

<u>Given the following data:</u>

  • Force 1 = 500 Newton
  • Distance 1 = 1.2 meter
  • Force 2 = 500 Newton
  • Distance 2 = 5 meter

To determine which of the students did the most work:

Mathematically, the work done by an object is given by the formula;

Work\;done = Force \times distance

<u>For </u><u>student 1</u><u>:</u>

Work\;done = 500 \times 1.2

Work done = 600 Joules

<u>For </u><u>student 2</u><u>:</u>

Work\;done = 500 \times 5

Work done = 2500 Joules.

Therefore, the student who did the most work is student 2 with 2500 Joules.

Anastasy [175]

Answer:

0 N

Explanation:

Applying,

F = qvBsin∅................. Equation 1

Where F = Force on the charge, q = charge, v = Velocity, B = magnetic charge, ∅ = angle between the velocity and the magnetic field.

From the question,

Given: q = 4.88×10⁻⁶ C, v = 265 m/s, B = 0.0579 T, ∅ = 0°

Substitute these values into equation 1

F = ( 4.88×10⁻⁶)(265)(0.0579)(sin0)

Since sin0° = 0,

Therefore,

F = 0 N
