Answer:

81.6 J

Explanation:

let the acceleration due to gravity = 9.8 m/s/s

W = F • s

F = newtons of force

s = distance travelled

the force to carry a mass is equal to mass multiplied by the acceleration due to gravity. This is confirmed using Sir Issac Newtons second and third law stating that the force of an object is equal to its mass multiplied by its acceleration (F = m • a) and that every action has an equal and opposite reaction, respectively. This means that the force of the object is equal to 8.45kg • 9.8 m/s/s, or 82.81 newtons of force.

F = 82.81 N

To find the distance displaced, you simply subtract 0.835m from 1.82m, giving a value of 0.985m.

s = 0.985m

Finally, in order to find work, you multiply 82.81 N by 0.985m resulting in a work equal to 81.6 J, after being rounded due to match the significant digits of the question.

We can conclude that Galaxy B is farther away from us than Galaxy A. Galaxy B is about 6 times farther away than Galaxy A.

The recession velocity of a galaxy is proportional to its distance from us, according to Hubble's Law. Specifically, the recession velocity v is given by:

v = H*d

where,

H = Hubble constant, which represents the rate of expansion of the universe

d = distance of the galaxy.

Assuming a value of H = 70 km/s/Mpc (which is a commonly used value), we can use the recession velocities of galaxies A and B to compare their distances from us.

If galaxy A has a recession velocity of 1000 km/s, its distance from us can be calculated as:

dA = vA / H = 1000 km/s / 70 km/s/Mpc ≈ 14.3 Mpc

Similarly, if galaxy B has a recession velocity of 6000 km/s, its distance from us can be calculated as:

dB = vB / H = 6000 km/s / 70 km/s/Mpc ≈ 85.7 Mpc

Therefore, we can conclude that Galaxy B is farther away from us than Galaxy A. In fact, galaxy B is about 6 times farther away than galaxy A.

In science, a hypothesis is a tentative explanation of an observation, while a scientific theory is a broader, well-tested explanation for a natural phenomenon backed by multiple lines of evidence.

In the scientific method, a hypothesis is an initial explanation or proposed solution to a specific observation or problem. It is often based on limited evidence or previous knowledge and serves as a starting point for further investigation. A hypothesis is testable and can be supported or refuted through experimentation or further observations. It represents a possible explanation that requires empirical evidence to validate or invalidate its validity.

On the other hand, a scientific theory is a well-established and comprehensive explanation for a natural phenomenon that has been extensively tested and supported by multiple lines of evidence. Unlike a hypothesis, a scientific theory goes beyond a single observation or experiment. It encompasses a broad range of observations, experimental results, and logical reasoning. A scientific theory provides a framework that can explain and predict various related phenomena. It is subject to ongoing scrutiny and refinement, but its validity and acceptance are based on its consistency with empirical evidence and its ability to make accurate predictions.

In summary, while a hypothesis is a tentative explanation of an observation, a scientific theory is a broader and well-tested explanation that is supported by multiple lines of evidence and can account for a range of related phenomena.

Explanation:

This is the formula for the change in distance (δx) of an object moving with constant acceleration (a) and initial velocity (v), one of the standard Equations of motion. To solve for t first rearrange

12at2+vt−δx=0

then apply the formula for solving a Quadratic equation if our equation is At2+Bt+C=0 then the solution is

t=−B±B2−4AC√2A,

here A=12a, B=v, C=−δx so plugging these in the formula gives

t=−v±✓v2−4(12a)(−δx)√2(12a) (Apply quandriatic equation)

simplifying

t=−v±v2+2aδx√a.

Note how there are two possible solutions one corresponding to the + and one to the -. Sometimes one of these will give a negative time, so you may want to eliminate that. Indeed if δx>0, v>0 and a>0 we only want the positive solution. In other cases you may want to consider both solutions, for instance if we thow a ball up in the air the initial velocity is positive and the acceleration is negative, it will pass a fixed height above your head twice, once on the way up and once on the way down.

The word from the list that best fits the definition increases the number of sunspots that can lead to warmer climates.

Sunspots are transitory spots on the Sun's photosphere that appear to be deeper than the surrounding areas.

They are zones of reduced surface heat caused by magnetic field flux concentrations that prevent convection.

Sunspots usually form in pairs with opposite magnetic polarities. This has an impact on the temperature on Earth, as well as radio reaction. The Earth would presumably be colder if sunspots didn't exist.

When sunspots form, they produce an increase in UV radiation that radiates from the sunspots' outer ring as they approach Earth.

This increase in UV radiation has an impact on the chemistry of the outer environment as well as the Earth's energy balance.

The idea that sunspots have an impact on Earth's ecology is still controversial, although it does exist.

It will take the car 16.67 sec to catch up with the truck.

Given the data in the question.

Since the car was stationary, then;

Initial velocity of the car; \(u_c = 0m/s\).

Final velocity of the car; \(v_c = 30m/s\).

Time taken for the car to reach given speed; \(t = 10s\).

At \(t = 0\), speed of truck; \(V_{truck} = 25m/s\)

First, we find the acceleration of the car, using the first equation of motion;

\(v = u + at\)

We make "a" the subject of the formula,

\(a = \frac{v-u}{t}\)

We substitute in our values and solve for "a"

\(a = \frac{30m/s - 0m/s}{10s}\)

\(a = 3m/s^2\)

Now, to determine how long will it take for the car to catch up with the truck.

Distance travelled by truck should be equal to distance travelled by car, so;

\(S_{truck\) = \(S_{car\)

We know that, speed; s = distance / time

So, distance of truck \(S_{truck\) = speed of truck × time \(= V_{truck} * t\)

Also, from the second equation of motion; distance "s" is;

\(s = ut + \frac{1}{2}at^2\)

So distance of the car \(S_{car} = ut + \frac{1}{2}at^2\)

We equate

\(S_{truck\) = \(S_{car\)

\(V_{truck} * t\) \(= ut + \frac{1}{2}at^2\)

we make "t" the subject of formula

we know that initial velocity of the car; u = 0

so, we divide both sides by "t"

\(V_{truck} = \frac{1}{2}at\)

\(t = \frac{2V_{truck}}{a}\)

We substitute in our values

\(t = \frac{2 * 25m/s}{3m/s^2}\)

\(t = 16.67s\)

Therefore, It will take the car 16.67 sec to catch up with the truck.

The first statement is true; if dim V = p and if S is a linearly dependent subset of V, then S contains more than p vectors.

The second statement is false; if S spans V and if T is a subset of V that contains more vectors than S, then T is linearlyly dependent.

Explanation:

If S is linearly dependent, then there is at least one vector in S that can be written as a linear combination of the remaining vectors. If this is the case, then this vector is redundant, and it can be removed from S. This means that we can repeat the process until we have removed all the redundant vectors from S.So, let us assume that S is a linearly dependent subset of V such that dim V = p, then we have the following:dim (span S) < dim Vp. So S contains more than p vectors.

The  second statement is false; if S spans V and if T is a subset of V that contains more vectors than S, then T is linearly dependent.

Explanation:Let us assume that S spans V and if T is a subset of V that contains more vectors than S, then T must have a vector not in S. We can add this vector to S to get a set that contains all the vectors in T. The resulting set is linearly dependent because it contains more vectors than S, which is known to span V.
