if the receiver has a totally absorbing panel measuring 20.0 cm by 35.0 cm oriented with its plane perpendicular to the direction the waves travel, what average force do these waves exert on the panel?

When you squeeze marshmallow its volume decreases.

Mass remains constant

ρ = m/v ,So density increases as volume decreases.

The amount of three-dimensional space that is occupied is measured by volume. [1] It is frequently measured quantitatively using SI-derived units (such the cubic meter and litre) or by other imperial or US-standard units. Volume and length (cubed) are related concepts. The volume of a container is typically understood to be the capacity of the container, i.e., the amount of fluid (gas or liquid) that the container might store, rather than. the amount of space. the container. itself occupies.

Volume was first determined using naturally occurring vessels of a comparable shape and later with standardized containers. Arithmetic formulas make it simple to determine the volume of several straightforward three-dimensional shapes. Integral calculus can be used to determine the volumes of more complex shapes.

Two protons and two neutrons are securely linked together to form composite particles known as alpha particles.

An elementary particle is a He nucleus, which consists of two protons and two neutrons. A particle with two protons has two units of charge. Four mass units of a particle are equal to two protons and two neutrons. As a result, 4He2 is the symbol for a particle.

Since an alpha particle is the same as a helium atom that has had its two electrons removed, it has two protons and two neutrons. No electrons are present in an alpha particle, hence the two protons' positive charge cannot be balanced.

Option A is a true. An SUV strikes a motorcycle that is standing still. The motorcycle can withstand more force than the SUV since it is stationary.

Every time one object applies force to another, the other object applies an equal and opposing force to the first. His third law argues that there is an equal and opposite reaction to every action (force) in nature. If you push a truck and a vehicle with the same amount of effort, the car will accelerate faster than the truck since it is lighter. Due to the full shopping cart's greater bulk compared to the empty one, it is simpler to push one than the other.

In the early stages of having enough grip, engineers frequently discuss "power to weight ratio" because this impacts acceleration. Since it takes longer (more time) to accelerate a heavier car with the same amount of power to go the same distance, more fuel is consumed.

The force needed to break another wire of the same length and material but twice the diameter is 200N.

Because the wires are made of the same material, their modulus of elasticity must be the same.

As a result, the ratio of longitudinal stress to longitudinal strain (Young's Modulus of Elasticity) must be the same. Now, the strains in both wires must be the same before they break.

Therefore,

stress = Young's modulus × strain,

both wires must be the same.

Because the second wire has a diameter twice that of the first, its area of cross section is four times that of the first. As a result, in order to generate the same stress, the force applied to the second wire must be four times that applied to the first wire.(since stress = force/cross section area).

Answer:

Explanation:

The displacement of the mouse is 76.01 cm along south-west at an angle 57.35° with south direction.

In mechanics, displacement refers to the distance that a particle or body moves in a particular direction. Generally, point masses are used to describe particles and bodies. This means that, without sacrificing generality, bodies can be thought of as having all of their mass concentrated in a single mathematical point.

The mouse  scurries 41 cm south and then  takes a 90-degree turn and scurries 64 cm west.

Hence, magnitude of resultant displacement = √( 41² + 64²) cm = 76.01 cm.

The direction of displacement is along south-west with an angle with south direction= tan⁻¹(64/41) = 57.35°.

The lowest amount of thermodynamic work, or energy, required to transfer an electron from a solid to a point in the vacuum immediately outside the solid surface is known as the work function (sometimes spelled workfunction). Here, the term "immediately" refers to a final electron position that is, on an atomic scale, far from the surface but still too close to the solid to be affected by ambient electric fields in the vacuum. The work function is a property of the material's surface rather than a characteristic of the substance in its bulk (depending on crystal face and contamination). When two dissimilar conductors are in complete equilibrium with one another, the space between them will have an embedded electric field due to the fact that relies on the material surface (electrically shorted to each other, and with equal temperatures). The work function refers to moving an electron many nanometers away from the surface so that the force between the electron and the surface's image charge may be disregarded. The electron must also be close to the surface in relation to any change in the surface structure, such as a change in the material composition, a surface coating, or a reconstruction, as well as the closest edge of a crystal facet.

The car traveled at an average speed of 97 miles per hour and the truck traveled at an average speed of 78 miles per hour.

Average speed is a measure of the distance traveled over time, or the rate at which someone or something is moving. It is calculated by dividing the total distance traveled by the total amount of time it took to travel that distance. For example, if a person runs one mile in five minutes, their average speed is 12 miles per hour (mph).

To calculate this, we must use the equation:

Distance = Rate x Time

For the car: 1448 = (97 + 19) x 8

For the truck: 1448 = (78 - 19) x 8

[tex]& \Rightarrow \vec{F}=(60)\left[\frac{7 \hat{i}+2.67 \hat{j}-2.5 \hat{k}}{\sqrt{7^2+2.67^2+2.5^2}}\right] \\& \Rightarrow \vec{F}=53.178 \hat{i}+20.284 \hat{j}-18.992 \hat{k}[/tex]

Moment about C will be;

[tex]& \vec{M}_C=\vec{r}_{C A} \times \vec{F}[/tex]

Substitute the value in above we get,

[tex]& \Rightarrow \vec{M}_C=\left|\begin{array}{ccc}\hat{i} & \hat{j} & \hat{k} \\0 & 4.33 & -2.5 \\53.178 & 20.284 & -18.992\end{array}\right| \\& \Rightarrow \vec{M}_C=-\mathbf{3 1 . 5} \hat{\mathbf{i}}-\mathbf{1 3 2 . 9} \hat{\mathbf{j}}-\mathbf{2 3 0 . 3 \hat { \mathbf { k } }}[/tex]

Therefore the Magnitude will be;

[tex]& M_C=\sqrt{(-31.5)^2+(-132.9)^2+(-230.3)^2} \\& \Rightarrow M_C=\mathbf{2 6 7 . 7} \mathrm{lb.ft}[/tex]

Note:- The correct question would be as bellow.

The curved rod has a radius of 5 ft. If a force of 60 lb acts at its end as shown, determine the moment of this force about point C.

Faraday is credited with discovering that a fluctuating magnetic field causes a current to flow.

According to Faraday's Law, a current whose magnitude depends on the rate of change of the magnetic field will flow when the strength of a magnetic field changes within a loop of wire. A shifting magnetic field causes an induced current. The induced current is accompanied by an induced emf. Without a battery in the circuit, a current can be generated. The induced emf can be described using Faraday's law of induction. According to Faraday's law, an electromotive force is created when the magnetic flux or magnetic field varies over time.
