Both the x and y components of A+B+C will individually be zero for the given vector.

In both mathematics and physics, the term "vector" is used informally to describe certain quantities (also known as "scalars") that cannot be described by a single number or by the constituent parts of some vector spaces. It is possible to add and scale both geometric vectors and tuples. These vector operations gave rise to the idea of a vector space, which is a set that is equipped with both a vector addition and a scalar multiplication and satisfies some axioms that generalize the key characteristics of operations on the aforementioned types of vectors. The terms Euclidean vector space and coordinate vector space are used to describe vector spaces constructed from geometric vectors and tuples, respectively.

From this information, it can be determined that

acceleration of the shot = 56 m/s^2

stoppage time = 0.123s

stoppage path length = 1.37m

The average acceleration while being shot by definition

a = [tex]\frac{\frac{80}{3.6} }{0.4}[/tex] = 56 m/s^2

Assuming that there is a constant acceleration we can determine the path covered during his acceleration as

s = 1/2a (0.4s)^2 = 4.5m

then we can find the stoppage time as

t3 = [tex]\frac{\frac{80}{3.6} }{180}[/tex] = 0.123s

Then the stoppage path length is defined as

s3 = [tex]\frac{(80/3.6)^2}{2a}[/tex] = 1.37m

Then the path length of travel with constant velocity is

s2 = 56.64m -s1 - s2 = 50.77m

Then time of flight

t2 = [tex]\frac{s_{2} }{80/3.6}[/tex] = 2.28s

Then we can determine the total time of flight as

t = t1 + t2 + t3 = 2.8s

Thus, we have

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. We will denote scalars with the italics, as in a or b.

A magnetic field, a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.

average pace and average pace are the same if the arrow constantly actions at a regular tremendous or bad speed. we will first pick out the places of high-quality and negative velocities.

Find the velocity equation first. It is y(derivatives: )'s

y'(t) = v(t) = [tex]66 - 3.72t[/tex]

Next, find the positive and negative values of this:

v(t) = 0 when t = [tex]66/3.72 = 17.74[/tex] seconds.

this means that v(t) is continually fine for all 3-time durations. As a result, all we want to do is calculate the average slope of y(t) during each period.

The correct answer is 0.00981 kJ/mol.

Every object we encounter has a binding force, and the energy that holds them together is the binding energy. The binding energy is the least amount of energy necessary to remove an electron, proton, or neutron from the nucleus. A nucleus contains electrons and protons that are strongly bound by energy.

Free energy of binding can be calculated using formula, Gbinding = dE coluombic + dEvdw + dGhyd. -TdS where Evdw+Ecoulombic is protein ligand interaction, dGhyd is change in hydration energy.

dS is entropy. dG hydration is Gpolar+Gnon polar. Inhibition constants are given for CBD and

If R is decreased for a given mass M then the velocity must increase to account for the angular momentum being a constant (conserved).

Answer:

it will stop after some time

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

Now speed =  Distance/ Time

⇒ Distance = speed * time=33.33*2.2=73.33

Thus distance traveled is 73.33 m

If diseases can be detected with the samples of serial dilution means that both patients have the disease. But, the second patient has the disease at a higher level than the first patient.

Serial dilution is a process of performing dilution of a sample in a series to know the number of organisms present in that sample. In a dilution of 1:5, the concentration is lesser than the 1/100 dilution, it is more likely to provide lesser numbers of pathogen colonies.

In 1/5 dilution, a total of 5 parts comprise 1 part of the sample as solute and 4 parts of the diluent or solvent. While, in a dilution of 1/100, a total of 100 parts comprises 1 part of solute and 99 parts of solvent. 1/100 would provide a large number of disease-causing organisms in the sample.

The homeowner has reported that sometimes the electric furnace trips the 240-V, 60-A circuit breaker connected to it. Upon examination, it is found that the furnace contains three 5000-W heating elements designed to turn on in stages.

The power rating of the circuit breaker = volt x current

= 240 x 60

= 14400 W

So, we have 3 units of 5000W each.

When the first unit is turned on, the consumption is 5000W and the circuit breaker does not trip. When two of the 5000W units are turned on, it adds up to a consumption of 10000W.

The circuit breaker is still intact. But when the 3rd 5000W unit is turned on, the consumption reached to 15,000W which is greater than the 14,400W mark, and thus the circuit breaker trips off.

So, switching on all three units at once can cause the circuit breaker to trip off.

So, the recommendation would be that at a particular time maximum of two units can be turned on.

Even such, the two units cannot be turned on in series or they won’t receive 240 V each.

Another recommendation would be to use a circuit breaker of a higher power rating, more than 15,000W so that there will be no tripping.

Given:

The Moon is in the first quarter of illumination.

In the first quarter of the moon the only one-fourth of the sun is illuminated and is observable from earth.

For this to happen only the visibly i.e. one-fourth of the moon should be reflecting back the light of the sun.
