If you approach a light beacon while traveling at one half the speed of light (0.5c) you woll measure the speed of light from the beacon to be:__________

This is thus because voltage divided by distance determines how strong an electric field is. The field is inversely proportional to this spacing at constant voltage.

More charge can flow via a stronger field, increasing capacitance.

In the simplest terms, the closer two items are near one another, the greater the influence; conversely, the further apart they are, the lesser the influence. As a result, capacitance decreases as spacing increases.

The ratio of the quantity of electric charge held on a conductor to an electric potential difference is known as capacitance. Self-capacitance and mutual capacitance are two concepts that are related to one another.

The differential equation for the concentration of the chemical is given by dc/dt = (3/10⁶)(1 - 100c)

Suppose that a(t) is the amount of chemical in the pond at time t.

So, a'(t) = rate of chemical inflow - the rate of chemical outflow.

So, da/dt = (0.01)300 - (a/10⁶)300

So, da/dt = 3 - 3a/10⁴

Now,

Since, c = a/v

Then, c' = a'/v

So, c' = (3 - 3a/10⁴)/10⁶

Or, c' = 3 (1 - a/10⁴)/10⁶

So, dc/dt = 3/10⁶ (1 - cv/10⁴)

So, dc/dt = (3/10⁶) (1 - 100c)

Therefore the differential equation for the concentration of the chemical is dc/dt = (3/10⁶)(1 - 100c)

The total time it is in the air for the ball is 3.672 s

Given:

Initial velocity = 18 m/s

We have to find the total time the ball is in the air.

By using the formula, we get,

t = v - u/a

Where t = time to reach the maximum height

v = final velocity of the ball = 0 m/s

u = initial velocity of ball = 18 m/s

a = acceleration due to gravity = -9.8

Acceleration of gravity is taken as negative because the ball is moving in the opposite direction.

t = 0 - 8/-9.8

t = 1.836 sec

Thus, time is taken by the ball to reach the ground again = time taken to reach the maximum height

So, the Total time required for the ball to reach the ground = 2t = 2 × 1.836

Total time required for the ball to reach the ground = 3.672 s

The weight of ourselves on the new planet will reduce by 1/4 factor.

We know that each body attracts another body, Now if we free fall on any planet then the natural acceleration or acceleration due to gravity force is called gravitation acceleration.

The gravitation acceleration is given by,

g = GM/R²

Where G is constant while M is the mass of the planet and R is the radius of that planet.

The value of g or gravitational acceleration for the earth is 9.81 m/sec².

Given that the new planet has a mass of 4 times then earth and diameter is also 4 times.

Since gravitation acceleration of earth ;

g = GM/R²

Since the diameter is 4 times so radius will also 4 times.

New planet acceleration ;

The electric field is 42750 N/C.

We need to know about the electric field to solve this problem. The electric field is the area that is affected by electric energy. The magnitude of the electric field can be determined as

E = k . Q / R²

where E is electric field, k is coulomb's constant (9 x 10⁹ Nm²/C²), Q is charge and R is radius.

From the question above, we know that

Q = 1.9 nC = 1.9 x 10¯⁹ C

R = 2 cm = 0.02 m

By substituting the parameters, we get

E = k . Q / R²

During this inattentive period, the distance traveled is 73.33 when the speed is 120 km/h and the time taken is 2.2 s.

Every moving object travels a particular distance over time. These two factors enable us to determine the speed. The frequency of displacement is the sole determinant of speed. The complete mobility of an object, regardless of direction, will be its distance. No matter where an object originates or finishes, distance measures how much ground it has travelled. A process, an action, or a condition's duration is the amount of time that can be measured or quantified. Speed is the rate at which an object travels along a path over time, whereas velocity is the speed and direction of an item's motion. In another sense, velocity is a vector, whereas speed is a scalar value. There is a formula that connects these three things. Speed can be thought of as a gauge for a body's rate of motion. The distance covered in a single unit of time is how it is defined.

Speed = Distance/ Time

We are given Average speed, = 120 km/h=(120 * 1000)/3600=33.33 m/s

Time, t=2.2s

Vector a b = c, and that |al |b| = |cl, vectors a and b oriented with respect to each other because they are perpendicular to each other.

A vector is an object that has both magnitude and a direction. Geometrically, we can picture vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction. The direction of vector is from its tail to its head.

Two vectors are the same if they have same magnitude and direction. This means that if we take a vector and translate it to a new position (without rotating it), then vector we obtain at the end of this process is the same vector we had in beginning.

Two examples of vectors are those that represent the force and velocity. Both the force and velocity are in a particular direction. The magnitude of vector would indicate the strength of the force or the speed associated with the velocity.

We denote vectors using the boldface as in a or b. Especially when writing by hand where one cannot easily write in boldface, people will sometimes denote vectors using the arrows , or they use the other markings. We won't need to use the arrows here. We denote magnitude of the vector a by |a|. When we want to refer to a number and stress that it is not a vector, we can call number a scalar.

The degree of disorder in a system is measured by entropy. Disorder refers to the "distance" and "separation" between molecules, particles, etc. Because they have rigid structures as opposed to gases and liquids, which have free structures, solids and crystals have less chaos. Compared to solids and crystalline formations, gases and liquids contain higher levels of chaos. Entropy increases as heat and energy are added, which indicates that disorder is spreading more quickly.
