I can’t see the QUESTION but go to my Question to get BRAINLIEST

Explanation:

Answer:

865.08 m

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 243 m/s

Height (h) of the cliff = 62 m

Horizontal distance (s) =?

Next, we shall determine the time taken for the cannon to get to the ground. This can be obtained as follow:

Height (h) of the cliff = 62 m

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) =?

h = ½gt²

62 = ½ × 9.8 × t²

62 = 4.9 × t²

Divide both side by 4.9

t² = 62/4.9

Take the square root of both side.

t = √(62/4.9)

t = 3.56 s

Finally, we shall determine the horizontal distance travelled by the cannon ball as shown below:

Initial velocity (u) = 243 m/s

Time (t) = 3.56 s

Horizontal distance (s) =?

s = ut

s = 243 × 3.56 s

s = 865.08 m

Thus, the cannon ball will impact the ground 865.08 m from the base of the cliff.

Explanation:

distance is how far they have actually driven. so just add up the distances:

59+97=156km

displacement is how far they are from their starting point. so they drive 59 kilometers east, then 97 kilometers west. so we subtract:

97-59=38km west of Olds

The distance travelled by the family was 156 km.

The displacement of the family is 38 km.

To find the distance and displacement, the given values are 59 km and 97 km.

           Distance of the family is how far they have actually driven . So, we just want to add up the distances.

Adding the given distances,

                        59+97=156km.

Thus, 156 km is the distance travelled by the family.

       Displacement of the family is how far they are from their starting point. so they started driving 59 kilometer east and then 97 kilometers west. We have to subtract the given distances.

Subtracting the given distances,          

                          97-59=38km west of Olds.

Thus, 38 km is the displacement of the family.

Explanat      Enthalpy of Vaporizationion:

This Hubble Space Telescope image shows Sirius A, the brightest star in our nighttime sky, along with its faint, tiny stellar companion, Sirius B. Astronomers overexposed the image of Sirius A so that the dim Sirius B (tiny dot at lower left) could be seen. The cross-shaped diffraction spikes and concentric rings around Sirius A, and the small ring around Sirius B, are artifacts produced within the telescope's imaging system. The two stars revolve around each other every 50 years. Sirius A, only 8.6 light-years from Earth, is the fifth closest star system known. (Image credit: NASA, H.E. Bond and E. Nelan (Space Telescope Science Institute, Baltimore, Md.); M. Barstow and M. Burleigh (University of Leicester, U.K.); and J.B. Holberg (University of Arizona))

Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive.

Stars start their lives as clouds of dust and gas. Gravity draws these clouds together. A small protostar forms, powered by the collapsing material. Protostars often form in densely packed clouds of gas and can be challenging to detect.

"Nature doesn't form stars in isolation," Mark Morris, of the University of California at Los Angeles (UCLS), said in a statement. "It forms them in clusters, out of natal clouds that collapse under their own gravity."

Smaller bodies — with less than 0.08 the sun's mass — cannot reach the stage of nuclear fusion at their core. Instead, they become brown dwarfs, stars that never ignite. But if the body has sufficient mass, the collapsing gas and dust burns hotter, eventually reaching temperatures sufficient to fuse hydrogen into helium. The star turns on and becomes a main sequence star, powered by hydrogen fusion. Fusion produces an outward pressure that balances with the inward pressure caused by gravity, stabilizing the star.

How long a main sequence star lives depends on how massive it is. A higher-mass star may have more material, but it burns through it faster due to higher core temperatures caused by greater gravitational forces. While the sun will spend about 10 billion years on the main sequence, a star 10 times as massive will stick around for only 20 million years. A red dwarf, which is half as massive as the sun, can last 80 to 100 billion years, which is far longer than the universe's age of 13.8 billion years. (This long lifetime is one reason red dwarfs are considered to be good sources for planets hosting life, because they are stable for such a long time.)

Bright shining star

More than 2,000 years ago, the Greek astronomer Hipparchus was the first to make a catalog of stars according to their brightness, according to Dave Rothstein, who participated in Cornell University's "Ask An Astronomer" website in 2003.

"Basically, he looked at the stars in the sky and classified them by how bright they appear — the brightest stars were 'magnitude 1,' the next brightest were 'magnitude 2,' etc., down to 'magnitude 6,' which were the faintest stars he could see," Rothstein wrote.

Modern instruments have improved measurements of brightness, making them more precise.

In the early 20th century, astronomers realized that the mass of a star is related to its luminosity, or how much light it produces. These are both related to the stellar temperature. Stars 10 times as massive as the sun shine more than a thousand times as much.

The mass and luminosity of a star also relate to its color. More massive stars are hotter and bluer, while less massive stars are cooler and have a reddish appearance. The sun falls in between the spectrum, given it a more yellowish appearance.

"The surface temperature of a star determines the color of light it emits," according to the worldwide Las Cumbres Observatory. "Blue stars are hotter than yellow stars, which are hotter than red stars."

This understanding lead to the creation of a plot known as the Hertzsprung-Russell (H-R) diagram, a graph of stars based on their brightness and color (which in turn shows their temperature). Most stars lie on a line known as the "main sequence," which runs from the top left (where hot stars are brighter) to the bottom right (where cool stars tend to be dimmer).

When the stars go out

Eventually, a main sequence star burns through the hydrogen in its core, reaching the end of its life cycle. At this point, it leaves the main sequence.

Answer:

Mass, m = 26.54kg

Explanation:

Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.

Mathematically, net force is given by the formula;

[tex] Fnet = Fapp + Fg[/tex]

Where;

Given the following data;

Net force, Fnet = 345

Acceleration, a = 3.2m/s²

To find mass;

Fnet = Fapp + Fg

Fnet = ma + mg

Fnet = m(a+g)

m = Fnet/(a+g)

We know that acceleration due to gravity, g = 9.8m/s²

Substituting into the equation, we have;

m = 345/(3.2 + 9.8)

m = 345/13

Mass, m = 26.54kg

Answer:

velocity is called vector quantity because it has both magnitude and direction.

Answer:

d = 4.47 [m]

Explanation:

To solve this problem we must make a free body diagram, where we can see the direction of the force acting with the appropriate angles. In the attached image we can see the free body diagram mentioned.

So in the image, we can see an angle of 65° with respect to the horizontal, therefore we can calculate the horizontal component of the force.

Fx = 22.4*cos (65)

Fx = - 9.46 [N] (it's negative because the force is pointing in the negative direction).

We can obtain the same result using 115° as the angle.

Fx = 22.4*cos (115)

Fx = 9.46 [N]

Now we know that work is defined as the product of the force by the distance, therefore we have.

Note: Always the work must be calculated with the force parallel

to the movement

W = F*d

Where:

W = work = 42.3 [J] (units of joules)

F = force parallel to the movement = 9.46 [N]

d = distance [m]

d = W/F

d = 42.3/9.46

d = 4.47 [m]

Explanation:

m=980n/9.8m/s^2=100kg

Mass is a constant quantity or property of a particle or an object. It doesn’t change.

Hence, mass of the man on the moon will be the same as mass of the man on earth; 100kg.

The weight of a particle or object is the force of gravity on the object; its is expressed as:

[tex]W = m * g[/tex]

Where m is mass and g is acceleration due to gravity.

Given that the man's weight on earth is 980N and acceleration due to gravity g = 9.8m/s².

We substitute the values into the equation and solve for "m" mass[tex]980N = m * 9.8m/s^2\\\\m = \frac{980kg.m/s^2}{9.8m/s^2}\\\\m = 100kg[/tex]

The man's mass on Earth is 100kg.

We know that, Mass is a constant quantity or property of a particle or object. It doesn’t change.

Hence, mass of the man on the moon will be the same as mass of the man on earth; 100kg.

The third table shown in the diagram below can be modelled with the equation, y = x + 2, therefore, it represents a linear equation.

A linear function is a function whose graph represents a straight line when the points are plotted, and also can be modelled by the equation, y = mx + b.

b is the value of y when x = 0 (y-intercept)

m is the slope or unit rate.

Thus, the third table shown in the diagram below can be modelled with the equation, y = x + 2, therefore, it represents a linear equation (see attachment). The last table has a constant slope of -3, hence it represents a linear function.

Table of functions

From the given table, we need to determine which of the table is a linear table. To determine that, we must check which of the table has a constant rate of change

Looking at the last table;

Slope = -4-(-2)/2-1

Slope = -4+1/1

Slope = -3

Since the last table has a constant slope of -3, hence it represents a linear function.

Answer:

Option B. 4

Explanation:

From the question given above, the following data were obtained:

Input force = 2.5 N

Output force = 10 N

Mechanical advantage (MA) =?

Mechanical advantage (MA) is simply defined as the ratio of the output force to the input force. Mathematically, it can be expressed as:

Mechanical advantage = Output : Input

MA = Output / Input

With the above formula, we can obtain the mechanical advantage of the pulley system as follow:

Input force = 2.5 N

Output force = 10 N

Mechanical advantage (MA) =?

MA = Output / Input

MA = 10/2.5

MA = 4

Thus, the mechanical advantage of the pulley system is 4.

Answer:

Option (b).

Explanation:

Two forces are acting perpendicularly on an object. We have, F₁ = 8.2 N and F₂ = 20.6 N

We need to find the net force acting on the object. When two forces are acting in perpendicular to each other, the net force on it is given by :

[tex]F=\sqrt{F_1^2+F_2^2} \\\\=\sqrt{8.2^2+20.6^2} \\\\=22.17\ N[/tex]

or

F = 22 N

Let [tex]\theta[/tex] is the angle. It can be given by :

[tex]\tan\theta=\dfrac{F_1}{F_2}\\\\\tan\theta=\dfrac{8.2}{20.6}\\\\=21.7^{\circ}[/tex]

or

[tex]\theta=22^{\circ}[/tex]

So, the net force is 22 N and the direction is 22° counterclockwise from F₁. Hence, the correct option is (b).
