Answer:

Uranium

Explanation:

The most important in atomic research is Uranium, Uranium Can be used as fuel for nuclear power plants and the nuclear reactors that run naval ships and submarines, so option A is correct.

The atom is the smallest unit of matter that may be divided without generating particles with an electrical charge. Additionally, it is the tiniest material with characteristics similar to chemical elements. As a result, the atom acts as the basic building block of chemistry.

Space makes up the majority of an atom. The rest is made up of a positively charged nucleus made up of protons and neutrons that are surrounded by a cloud of negatively charged electrons. The nucleus is small and dense when compared to electrons, which are the lightest charged particles in nature. Electric forces, link electrons to the nucleus of atoms, causing them to be drawn to any positive charge.

Uranium that has been "enriched" to have a higher concentration of U-235 can power nuclear power plants, and It can also be applied to nuclear weapons.

Therefore, uranium is the most important in atomic research.

a) The amplitude is approximately 1.428 m.

b) The maximum acceleration is approximately 378.57 m/\(s^_2\).

c) The maximum force is approximately 785.4 N.

To track down the sufficiency, greatest speed increase, and most extreme power applied by the spring, we can utilize the standards of consonant movement.

a) The sufficiency (A) can be resolved utilizing the energy preservation guideline. At t = 0, the block is moving with a speed of - 10.0 m/s. Since there is no outer power following up on the framework, the complete mechanical energy is saved. The likely energy at the outrageous marks of the movement is zero, and the whole mechanical energy is as motor energy. In this way, we can compute the adequacy utilizing the recipe:

0.5 * k * \(A^_2\) = 0.5 * m * \(v^_2\)

0.5 * 550 N/m * \(A^_2\)= 0.5 * 2.00 kg * \((10.0 m/s)^_2\)

Tackling for A, we view as A = 1.428 m.

b) The greatest speed increase (amax) of the block can be resolved involving the condition for consonant movement:

amax = \(ω^_2\) * A

where ω is the precise recurrence. The precise recurrence can be determined as:

\(ω\)= sqrt(k/m)

\(ω\)= sqrt(550 N/m/2.00 kg) ≈ 16.61 rad/s

Subbing the qualities, we find:

amax =\((16.61 rad/s)^_2\) * 1.428 m ≈ 378.57 m/\(s^_2\)

c) The most extreme power (Fmax) applied by the spring can be determined utilizing Hooke's regulation:

Fmax = k * A

Subbing the given qualities, we have:

Fmax = 550 N/m * 1.428 m ≈ 785.4 N

In this way, the abundancy is roughly 1.428 m, the greatest speed increase is around 378.57 m/\(s^_2\), and the most extreme power applied by the spring is around 785.4 N.

2. If current doubles, time halves for same charge flow.

3. If the current in a circuit is switched on for twice as long, the total charge that flows through the circuit doubles.

The principle behind this is Ohm's law, wherein the current (I) that runs through a circuit is proportionate to the amount of charge (Q) that passes through the circuit in a given period. As the present is multiplied by two, correspondingly the quantity of charge also increases by two.

If the electric current is increased by two times its original value, the duration required for the identical quantity of charge to pass through is reduced by half. The reason for this is that the equation Q = I * t reflects the correlation among charge (Q), current (I), and time (t).

If the duration of the current in a circuit is doubled, then the amount of charge that passes through the circuit also doubles. The reason behind this is that the correlation linking charge (Q), current (I), and time (t) is defined by the formula Q = I * t.

Newton's third law of motion states that for every action, there is an equal and opposite reaction. The action-reaction pair is used to describe the interaction between two objects. Therefore, when a car is speeding up as it drives along a level road, an action-reaction pair occurs.

An action-reaction pair is a pair of forces that are equal in strength and opposite in direction. When an object exerts a force on another object, the second object exerts an equal and opposite force on the first object. The action-reaction pair when a car speeds up as it drives along a level road can be explained as follows: Action force: The car exerts a force on the road in the forward direction. This is the action force. Reaction force: The road exerts a force on the car in the backward direction. This is the reaction force.

I agree with Eve's hypothesis that the cart full of groceries applied more force to the empty cart than the empty cart applied to the full cart. This can be explained by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.

When the two carts collide, they exert equal and opposite forces on each other. The force exerted by the full cart on the empty cart is equal in magnitude but opposite in direction to the force exerted by the empty cart on the full cart. According to Newton's third law, these forces are a pair of action-reaction forces.

The force experienced by an object can be calculated using the equation F = m * a, where F is the force, m is the mass of the object, and a is the acceleration. Since the masses of the two carts are different (20 kg for the empty cart and 40 kg for the full cart), the force experienced by each cart will be different if the acceleration is the same.

Given that the carts collide, it is reasonable to assume that they experience the same acceleration in the opposite directions. Therefore, the force experienced by the empty cart will be smaller than the force experienced by the full cart. This is because the force is directly proportional to the mass according to Newton's second law (F = m * a).

In conclusion, according to Newton's third law of motion, the cart full of groceries applied more force to the empty cart than the empty cart applied to the full cart. The difference in mass between the two carts results in a difference in the forces they exert on each other during the collision.

To photograph a circular diffraction pattern with a central maximum diameter of 0.90 cm, you need to place the viewing screen 0.44 m (44 cm) behind the 0.13-mm-diameter pinhole.

This is calculated as follows:
First, calculate the diameter of the central maximum (D) using the formula

D = λ × D0/d,

where λ is the wavelength of the light (633 nm in this case), D0 is the diameter of the pinhole (0.13 mm) and d is the distance between the pinhole and the viewing screen (the quantity you are solving for).

So,

D = \((6.33 \times 10^{-9}) \times (0.13 \times  10{-3}) / d\)

= 0.9 cm

Now, calculate the distance between the pinhole and the viewing screen (d). Rearrange the formula above to make d the subject of the equation and solve. So,

d = (633 × 10-9) × (0.13 ×\(10^{-3\)) / 0.9

d = 0.44 m (44 cm).

The primary difference between speed and velocity is that speed is a scalar quantity that describes how fast an object is moving, while velocity is a vector quantity that describes how fast an object is moving in a particular direction

Speed and velocity are two critical concepts in physics. They are used to describe the motion of an object. While both describe how fast an object is moving, there are some fundamental differences between the two. Let's explore these differences.

What is speed?

Speed is a scalar quantity that describes how quickly an object moves. It is measured in meters per second (m/s) or kilometers per hour (km/h).

Speed can be calculated using the following formula:

speed = distance ÷ time

For example,

if an object covers a distance of 150 meters in 10 seconds, its speed can be calculated as follows:

Speed = distance ÷ time= 150 meters ÷ 10 seconds= 15 meters per second (m/s)

What is velocity?

Velocity, on the other hand, is a vector quantity that describes how fast an object is moving in a particular direction. It is measured in meters per second (m/s) or kilometers per hour (km/h).

Velocity can be calculated using the following formula:

velocity = displacement ÷ time

For example, if an object travels a displacement of 150 meters in 10 seconds in a specific direction, its velocity can be calculated as follows:

Velocity = displacement ÷ time= 150 meters ÷ 10 seconds= 15 meters per second (m/s) in a specific direction.
