The box can't move on its own because of static friction; this friction must be overcome by an opposing force that is strong enough for the box to move. When surfaces are moving, a force called kinetic friction, also known as dynamic friction, opposes the relative movement of the surfaces.

A force that holds an item at rest is called static friction. The friction that people experience when attempting to move a stationary object on a surface without actually causing any relative motion between the body and the surface is defined as:

The new acceleration would be 24.0 m/s/s.

Acceleration is the rate of change of velocity of an object over time. It is a vector quantity, meaning that it has both magnitude and direction. Acceleration is the result of applying a force to an object, and can be described mathematically as the change in velocity (or speed) divided by the time it takes for the acceleration to occur. Acceleration can also be caused by a change in the direction of motion and is measured in meters per second squared (m/s2). It is an important concept in physics, and is used to describe motion in objects ranging from cars to planets.

The new acceleration would be 24.0 m/s/s. This is because the acceleration of an object is directly proportional to the force applied to it, and inversely proportional to its mass. Therefore, doubling the mass of the object would halve the acceleration, since the force applied to the object remains the same.

Explanation:

Activity: Is it the same?!

Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface. The simplest example of visible light reflection is the surface of a smooth pool of water, where incident light is reflected in an orderly manner to produce a clear image of the scenery surrounding the pool. Throw a rock into the pool (see Figure 1), and the water is perturbed to form waves, which disrupt the reflection by scattering the reflected light rays in all directions.

Some of the earliest accounts of light reflection originate from the ancient Greek mathematician Euclid, who conducted a series of experiments around 300 BC, and appears to have had a good understanding of how light is reflected. However, it wasn't until a millennium and a half later that the Arab scientist Alhazen proposed a law describing exactly what happens to a light ray when it strikes a smooth surface and then bounces off into space.

In this activity you will be working as an engineer that is working to modify different kinds of digital cameras and to study the effect of changing incident angle on the reflected angle.

If a firefighter dropped a person onto the safety net, and right before the person hit the net they had a velocity of 12m/s and 1800 J of kinetic energy, then 28.70 kg was the mass of the person.

Kinetic energy is a type of power that a moving object or particle possesses. An item accumulates kinetic energy when work, which involves the transfer of energy, is performed on it by exerting a net force. A moving object or particle has kinetic energy, which relies on both its mass and its rate of motion.

The type of motion might be vibration, rotation on an axis, translation (or travel along a path through one point to another), or any combinations of these.

E= mv²/2

m(11.2)²/2= 1800.

m(11.2)²= 3600

125.44m= 3600

m= 3600/125.44= 28.70 kg

The final eqilibrium tempreture of the tin water mixture, given that the was initially at 10 °C is 18.5 °C

The equilibrium temperature of the tin and water mixture can be obtained as follow:

From calorimetry, we understood that:

Heat loss = Heat gain

MC(T - Tₑ) = MᵥᵥC(Tₑ - Tᵥᵥ)

Inputting the various parameters, we have:

0.225 × 230 (97.5 - Tₑ) = 0.115 × 4184(Tₑ - 10)

51.75(97.5 - Tₑ) = 481.16(Tₑ - 10)

Clear bracket

5045.625 - 51.75Tₑ = 481.16Tₑ - 4811.6

Collect like terms

5045.625 + 4811.6 = 481.16Tₑ + 51.75Tₑ

9857.225 = 532.91Tₑ

Divide both side by 532.91

Explanation:

(a) mass (m) =0.45kg

Height(h) =8.5m

Gravity (g) =10m/s^2

But P. E (Potential Energy) = mass × gravity × height

P. E = 0.45×10×8.5

P. E = 34.0J

(b) using v^2=u^2 - 2gs

Where v = final velocity

u= initial velocity

g = gravity

s =distance

But at maximum height v =0

0^2= u^2 - 2gs

Transpose u^2 we have

u^2 = 2gs

u^2 = 2×10×8.5

u^2 = 170

u = square root of 170

u = 13.038m/s

Explanation:

If answer is correct feel free to replay me for explanation.

In most applications, the braking torque of the friction brakes should be adequate enough to bring the vehicle to a complete stop within a reasonable distance.

This is important for safety reasons and to prevent accidents.

The braking torque required depends on several factors, including the weight of the vehicle, the speed at which it is traveling, and the road conditions.

To calculate the required braking torque, one can use the equation:

Braking torque = vehicle weight x deceleration x radius of the brake rotor

Deceleration is the rate at which the vehicle slows down, and the radius of the brake rotor is the distance from the center of the rotor to the point where the brake pads make contact.

Once the required braking torque is calculated, the brake system can be designed accordingly.

This may involve selecting the appropriate brake pad material, ensuring proper brake cooling, and selecting the right brake rotor size and design.

It is important to note that the braking torque should not be excessive, as this can cause premature wear of the brake components and reduce their effectiveness over time.

Additionally, excessive braking torque can lead to wheel lock-up and skidding, which can be dangerous.

Explanation:

Answer:

50 cm3 of 1M hydrochloric acid is a six-fold excess of acid. In this reaction, the magnesium and acid are gradually used up. However the acid is in excess, so it is mainly the loss of magnesium (surface area becomes smaller) that causes the change in the rate.

Explanation:

The equation for the reaction is: magnesium + hydrochloric acid → magnesium chloride + hydrogen

Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)

Students follow the rate of reaction between magnesium and the acid, by measuring the amount of gas produced at 10 second intervals.

3 cm of magnesium ribbon typically has a mass of 0.04 g and yields 40 cm3 of hydrogen when reacted with excess acid. 50 cm3 of 1M hydrochloric acid is a six-fold excess of acid.

In this reaction, the magnesium and acid are gradually used up. However the acid is in excess, so it is mainly the loss of magnesium (surface area becomes smaller) that causes the change in the rate.

If a graph of volume (y-axis) against time (x-axis) is drawn, the slope of the graph is steepest at the beginning. This shows that the reaction is fastest at the start. As the magnesium is used up, the rate falls. This can be seen on the graph, as the slope becomes less steep and then levels out when the reaction has stopped (when no more gas is produced).

The reaction is exothermic, but the dilute acid is in excess and the rise in temperature is only of the order of 3.5˚C. There is some acceleration of the reaction rate due to the rise in temperature. Some students might notice the flask becoming slightly warm and they could be asked how this would affect the rate of reaction, and how they might adapt the experiment to make it a ‘fair test’.

In the simplified river flow, the water flows in the x-direction with a constant velocity U. To show that this flow satisfies the equation of continuity, we need to apply the continuity equation.

The continuity equation is given by:$$\frac{\partial \rho}{\partial t} + \nabla \cdot (\rho \vec{v}) = 0$$where ρ is the density of the fluid, t is time, v is the velocity vector, and ∇· is the divergence operator. In 1D, the continuity equation reduces to:$$\frac{\partial \rho}{\partial t} + \frac{\partial (\rho u)}{\partial x} = 0$$where u is the velocity in the x-direction. For the simplified river flow, the velocity is constant in the x-direction, so the second term in the equation above becomes:$$\frac{\partial (\rho u)}{\partial x} = u \frac{\partial \rho}{\partial x}$.

Substituting this into the continuity equation yields:$$\frac{\partial \rho}{\partial t} + u \frac{\partial \rho}{\partial x} = 0$$This is a first-order linear partial differential equation, which can be solved using the method of characteristics. The characteristic curves are given by:$$\frac{dx}{dt} = u, \ \ \ \frac{d\rho}{dt} = 0$$The second equation tells us that the density is constant along each characteristic curve. Therefore, the continuity equation is satisfied for the simplified river flow.

Answer:

When you have two materials with the same index of refraction, it means that if they are touched by a ray of light it won't have a chance, and its form would prevail.

Explanation:

The reason behind this is that in the first place. When light passes through an object of certain refraction it is modified from its natural state, allowing it to change in color to the human eye or many other effects in other perceptive elements. However, when the same light passes through two objects with the same refraction due to their physical characteristics, it doesn't change because once it comes out of the first one it will suffer the same effect from the last one. For it to change the refraction would have to be higher or lower. Then it would be modified. The reason is because the dimensions are not modified. Because at some point the ray of light has to come out of the first one to enter the second one.
