Answer:

39

Explanation:

Relative mass does not need to be calculated as it is listed on the periodic table. Potassium's relative atomic mass is around 39.

Answer:

11

Explanation:

An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 - 11 this atom will have 12 neutrons. Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons

Answer:

Sodium: Na

It is a metal

It's family is Alkali metals

Its atomic number is 11

It has 12 neutrons, 11 protons, 11 electrons

Answer:

Rolling Friction is the force

Answer:

Rolling friction

Explanation:

this is a friction that acts on objects when they are rolling over a surface.

Answer:

If an object is changing its velocity -whether by a constant amount or a varying amount

Explanation:

then it is an accelerating object. And an object with a constant velocity is not accelerating.

Answer:

the object can be accerleratting because the object supports it then later goes up for example a ball. if it supports that means its positive. if it has the weight like i mean by initially at rest. this means its negative. Hope this helps!

Explanation:

Answer:

power is the rate at which work is accomplished

The equilibrium of the reaction (a), (d), and (e) will shift to the left side when the temperature is increased.

Equilibrium law states that if the dynamic equilibrium gets disturbed by changing the conditions such as temperature, pressure, etc., then to reestablish equilibrium, the position of equilibrium will shift to counteract the change.

As we know that if the change of enthalpy (ΔH) is negative then the reaction is exothermic in nature and if the change in the enthalpy is positive the reaction is endothermic in nature.

Therefore, the reaction (a), (d), and (e) are exothermic reactions, and the reaction (b) and (c) are endothermic reactions.

On increasing the temperature, if the forward reaction is exothermic. Then the equilibrium will shift to the reactant side or left so that excess heat will be absorbed in the backward reaction.

Therefore,  when the temperature is increased, the reaction (a), (d), and (e) will shift the equilibria to the left side.

Answer: The wave interaction described in the scenario is known as constructive interference.

Explanation:

Constructive interference occurs when two waves meet and combine in such a way that their amplitudes add up, resulting in a larger wave. In this case, Max's steady pattern of jumping creates small waves on the trampoline, with a certain amplitude.

When Jimmy starts jumping on the trampoline, his waves combine with Max's waves. If the peaks and troughs of both waves align perfectly, they will add up, resulting in a wave with a larger amplitude. This alignment of peaks and troughs leads to constructive interference, causing Max to go twice as high without any additional effort.

The reason behind this phenomenon lies in the nature of waves. When waves meet, their amplitudes can either add up or cancel out, depending on their relative positions. In the case of constructive interference, the peaks of one wave align with the peaks of the other wave, and the troughs align with the troughs, resulting in an increased amplitude. Conversely, in destructive interference, the peaks align with the troughs, leading to a cancellation or reduction in amplitude.

So, in the scenario, Jimmy's waves align with Max's waves in such a way that their amplitudes combine constructively, resulting in Max going twice as high on the trampoline without exerting any extra effort.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

Maybe they might use that math thing for Science.

The piece of evidence changed thinking about the channel on Mars because it shows that the rock was formed next to flowing water as such rock formations exist on Earth and were formed by flowing water.

The geologic process that could have created the channel on Mars is water moving. We can infer from the image that water running across the terrain on Mars created channels similar to those on Earth.

We can claim that the flowing of water creates the channels on Mars because when the water runs for a long period from the same region, it takes the sediments and creates channels.

Answer:

B

Explanation:

Because the sharpener is attached to an electrical outlet

When a student uses an electric sharpener to sharpen a pencil then from electrical energy to mechanical energy. Therefore, option (B) is correct.

Mechanical energy can be defined as the addition of kinetic energy and potential energy that is used to perform work.  The total mechanical energy is conserved when the forces performing work are conservative in nature.

The principle of conservation of mechanical energy can be described as when an isolated system is under the influence of conservative forces, then the mechanical energy is constant. If a body moves in the opposite direction of a net force, the potential energy will increase and the speed of the object changes, the kinetic energy also changes.

Many devices are used to transform mechanical energy to or from other forms of energy, such as an electric motor converts electrical energy to mechanical energy,

An electric sharpener converts mechanical energy into electrical energy. Therefore, option (B) is correct.

Among the various ways that agriculture has an impact on society are the provision of food, habitat, and employment opportunities; the provision of raw materials for food and other goods; and the development of robust economies through commerce.

A large number of species use pasture and crops as both a habitat and a source of food, making up around 50% of the planet's livable land. Sustainable management of agricultural operations has the potential to safeguard watersheds, restore significant habitats, and improve the quality of the soil and water supply.

Answer:

A stimulus that the nervous system would react to a electrical impulse being made in response to the stimulus.

Explanation:

The system which send messages back and forth between the brain and the body is known as nervous system. It is the brain which controls all the body functions.

The changes in the environmental conditions to which the living organisms respond is defined as the stimuli. Every organisms responds when an external stimulus acts on it. The response given to the stimulus by various organisms is known as coordination.

One of the best examples for the stimulus and response is touching a hot object and withdrawing the hand. When you accidentally touch a hot object, we will withdraw our hand automatically. Here the heat of the object is the stimulus and withdrawing hand is the response.

Similarly if we are hungry, we will eat some food. It is also an example of stimulus and response.

Thus the change in the environment is the stimulus and the reaction of the organism to it is the response.
