The number 12 tells us that the mirror is a concave mirror, as this is the only type of mirror that can produce an image of a real object that is magnified.

An image that has been enlarged is reflected back from a concave mirror's shallow inward curve, which concentrates light rays into a single point.

Contrast this with a convex mirror, which has a curved outer surface that spreads the light rays out, giving the image less clarity.

A magnification of 12 indicates that the size of the image is 12 times larger than the size of the object. Magnification is computed by dividing the size of the image by the size of the object.

C. unlikely to combine with other elements.

Explanation:

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.

Noble gases are chemical elements with eight valence electrons and as such have a full octet. Some examples are argon, neon, etc.

Hence, the full octet makes the gas (neon) unlikely to combine with other elements.

Answer:

all of the particles are at rest (v = 0)

Explanation:

Therefore, since nothing is moving, the total momentum of the system must also be zero.

As a system consisting of two particles is known to have zero total momentum, the kinetic energy of the system will be zero as well.

Momentum is the product of a particle's mass and velocity. Momentum is a vector quantity, which means it has a magnitude as well as a direction.

According to Isaac Newton's second law of motion, the time rate of change of momentum equals the force acting on the particle.

Momentum describes the relationship between an object's mass, velocity, and direction.

Any change in momentum generates force. As a result, a change in momentum is used to calculate the force acting on the object.

Because the total kinetic energy is zero, all of the particles are at rest (v = 0). As a result, because nothing is moving, the system's total momentum must also be zero.

Thus, the statement is true.

Answer:

kinetic energy

Explanation:

Motors change electrical energy into kinetic energy. The spinning movement of the motor is used to do work, for example, the wheels on a toy car.

Answer:

hope this works

Explanation:

Kinetic energy is defined as the energy of a moving object.

A thrown football, a speeding automobile, a marathon runner, or a rock falling from a cliff, are examples of objects that have kinetic energy.

When an object is thrown straight up, it initially accelerates upward as it gains speed. Once it reaches the very top of its path, it stops accelerating and begins to decelerate due to gravity, until it reaches its maximum height and starts to fall back down.

At the very top of its path, the acceleration of the red ball is zero, because it is no longer gaining speed, it has reached its maximum height and is starting to fall back down.

The acceleration of the red ball at the very top of its path is zero m/s^2.

It's important to note that the initial velocity is 7m/s and the acceleration is the change of velocity over time, which is equal to zero because the velocity is the same and hasn't changed, the ball is at the highest point and it is not moving anymore.

If we maintain the percent error in gexp constant, the ratio Δgexp/gexp should rise as l falls and fall as l rises. It implies that the experimental prediction of g is more sensitive to variations in string length for shorter lengths than longer lengths.

To compare the calculated uncertainty in gexp for the shortest and longest values of l to the percent error in gexp, we need to refer to the lab manual for the derivation of uncertainty in g. Let's assume that the lab manual provides the following formula for the uncertainty in g:

Δg = \((2π/T^2)\) * ΔT

where T is the period of oscillation, ΔT is the uncertainty in T, and Δg is the uncertainty in the acceleration due to gravity (g).

Now, let's consider the effect of the length of the string on the experimental prediction. From the formula for the period of oscillation of a simple pendulum, we know that:

T = 2π√(l/g)

where l is the length of the string and g is the acceleration due to gravity.

If we differentiate this equation with respect to l, we get:

dT/dl = π/(gT√(l/g))

Using this equation and the formula for the uncertainty in g, we can derive the uncertainty in T due to the uncertainty in l:

ΔT = \((T^2/(4π^2*l))\) * Δl

Substituting this expression for ΔT into the formula for the uncertainty in g, we get:

Δg = \((2π^2/(T^3*l))\) * Δl

Now, let's consider the shortest and longest values of l. If we assume that the percent error in gexp is the same for both values of l, then we can write:

Δg/gexp = Δl/l

Therefore, we can compare the calculated uncertainty in gexp for the shortest and longest values of l to the percent error in gexp by comparing the ratios Δgexp/gexp and Δl/l for the two values of l.

If we assume that the uncertainty in l is the same for both values, then the ratio Δl/l is the same for both values. Therefore, any difference in the ratio Δgexp/gexp between the two values of l must be due to the effect of l on the experimental prediction.

From the formula for the uncertainty in gexp, we can see that Δgexp is inversely proportional to \(T^3\) and l.

The statement "When you are looking at the sun, you are seeing the sun as it is at this exact moment" is FALSE because what we see is the image of the sun  8.3 minutes ago.

When you are looking at the sun, you are not seeing the sun as it is at this exact moment. This is because the sun is approximately 8.3 light minutes away from Earth. This means that it takes light from the sun 8.3 minutes to reach Earth. So, when you are looking at the sun, you are actually seeing the sun as it was 8.3 minutes ago.

Due to light need time to travel, the images we see of the sun, as well as other celestial objects, are always slightly "delayed" by the time it takes for the light to reach us.

The equation for energy in the context of fluid dynamics, specifically in Computational Fluid Dynamics (CFD), is typically represented by the conservation of energy equation, also known as the energy equation or the first law of thermodynamics. The equation can be expressed as:

ρ * (du/dt + u * ∇u) = -∇p + ∇⋅(μ * (∇u + (∇u)^T)) + ρ * g + Q

where:

ρ is the density of the fluid

u is the velocity vector

t is time

∇u represents the gradient of velocity

p is the pressure

μ is the dynamic viscosity

g is the gravitational acceleration vector

Q represents any external heat source/sink

The physical meaning of energy in CFD is the total energy of the fluid system, which includes kinetic energy (associated with the motion of the fluid), potential energy (associated with the elevation of the fluid due to gravity), and internal energy (associated with the fluid's temperature and pressure). The energy equation describes how this total energy is conserved and transformed within the fluid system.

In CFD simulations, the energy equation plays a crucial role in modeling the energy transfer, heat transfer, and flow characteristics within the fluid. It helps in understanding how energy is distributed, dissipated, and exchanged within the fluid domain. By solving the energy equation numerically, CFD simulations can predict temperature profiles, flow patterns, heat transfer rates, and other important parameters that are essential for various engineering applications, such as designing efficient cooling systems, optimizing combustion processes, and analyzing thermal behavior in fluid flows.

The clock's period on the moon will be longer compared to that on Earth.

It is approximately √(6) times longer.

The period of a clock refers to the time it takes for one complete cycle or revolution. In the case of a pendulum clock, for example, the period is determined by the length of the pendulum and the acceleration due to gravity.

On Earth, the acceleration due to gravity is approximately 9.8 m/s². However, on the moon, the gravity is about 1/6th that of Earth, which means the acceleration due to gravity on the moon is approximately 1/6th of 9.8 m/s².

Let's denote the period of the clock on Earth as T_Earth and the period of the clock on the moon as T_Moon.

Since the acceleration due to gravity on the moon is 1/6th that of Earth, we can express the relationship between the periods as follows:

T_Moon = T_Earth * √(g_Earth/g_Moon)

where g_Earth is the acceleration due to gravity on Earth and g_Moon is the acceleration due to gravity on the moon.

Plugging in the values, we have:

T_Moon = T_Earth * √(9.8 m/s² / (1/6 * 9.8 m/s²))

= T_Earth * √(6)

Therefore, the clock's period on the moon will be longer compared to that on Earth, specifically, approximately √(6) times longer.

Calculate the acceleration of the car using the following kinematic equation.

v = u + at

Solve for a.

a = (v-u)/t

a = (25 m/s-12 m/s)/(6.0 s) = 2.167 m/s²

Calculate the displacement of the car using the following kinematic equation.

s =½(v + u)t

s = 0.5 × (25 m/s + 12 m/s) × 6.0 s = 111 m

Acceleration is a degree of the rate of change of speed of an object. Velocity is a vector quantity that describes both the speed and direction of an object's motion, while acceleration is a vector quantity that describes the rate at which an object's velocity changes.

Acceleration can be caused by a number of factors, including forces such as gravity, friction, and air resistance. For example, when a ball is thrown upwards, the force of gravity causes it to slow down as it moves higher, resulting in a negative acceleration.In physics, acceleration is typically measured in meters per second squared (m/s²). An object is said to be accelerating if it is changing its velocity, either by increasing or decreasing its speed, changing its direction, or both.
