Explanation:

The force the rocket exerts on the air is in the direction opposite to

the force that the air exerts on the rocket.

Newton's third law describe the forces affecting a rocket as it descends to Earth's surface because: C. The force the rocket exerts on the air is in the direction opposite to  the force that the air exerts on the rocket.

Newton's Third Law of Motion states that for every action there exist an equal but opposite reaction.

This ultimately implies that, Newton's Third Law of Motion is a law that is generally based on action-reaction force pairs.

Answer:

c) more energy is trapped, which leads to an increase in Earth's global temperature

Explanation:

Greenhouse effect is caused by the trapping of the reflected energy from the surface of the earth into the atmosphere by some gases. Thus with time causes more energy to be trapped in the atmosphere, which cause an increase in the average ambient temperature of the earth. Because the energy could not escape out into space beyond the earth's atmosphere. Therefore, an increase in Earth's global temperature.

Answer:

Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth.

Explanation:

Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies. The age, distribution, and composition of the stars in a galaxy trace the history, dynamics, and evolution of that galaxy. Moreover, stars are responsible for the manufacture and distribution of heavy elements such as carbon, nitrogen, and oxygen, and their characteristics are intimately tied to the characteristics of the planetary systems that may coalesce about them. Consequently, the study of the birth, life, and death of stars is central to the field of astronomy.

Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. As the cloud collapses, the material at the center begins to heat up. Known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. Three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the Milky Way are paired or in groups of multiple stars.

Answer:

stars are are giant balls of gases...yes their light is natural, it emits light due to chemical activities in the cor of star. We are living in the milky way and the nearest galaxy to us is Andromeda galaxy which is about 2.5x more larger than our galaxy, no there are no proofs for presence of aliens

In a distance time graph, when the x and y values are positive (in first quadrant), the runner is moving forward.

While, if the distance value ( in the y axis) is negative, the runner is moving backwards ( towards the start) .

Hope it helps :)

A distance-time graph shows how far an object has travelled in a certain time. This is a simple line graph that plots observations by distance versus time.

 The distance is transferred to the Y axis.

Time is plotted on the X-axis.

The distance-time graph when we study the motion of bodies. If you set the distance and time of the movement of the object and transfer the same data to a rectangular graph, you will get a distance-time graph corresponding to the movement of the object.

Answer:

[tex]a=-1.388\ m/s^2[/tex]

Explanation:

Initial velocity of car, u = 50 km/h = 13.88 m/s

It stops, v = 0

Time, t = 10 s

We need to find the car's deceleration while slowing down. As the car is slowing down, it will have deceleration. It can be calculated as follows :

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{0-13.88 }{10}\\\\a=-1.388\ m/s^2[/tex]

So, the deceleration of the car is [tex]1.388\ m/s^2[/tex].

Answer:

8 m/s².

Explanation:

We'll begin by calculating the force applied to 0.25 Kg hockey puck. This is illustrated below:

Mass (m) = 0.25 Kg

Acceleration (a) = 16 m/s²

Force (F) =.?

Force (F) = mass (m) × acceleration (a)

F = ma

F = 0.25 × 16

F = 4 N

Therefore, a force of4 N was applied to the 0.25 Kg hockey puck.

Finally, we shall determine the acceleration in which the 4 N force will give to the 0.50 Kg baseball. This can be obtained as follow:

Mass (m) = 0.50 Kg

Force (F) = 4 N

Acceleration (a) =?

F = ma

4 = 0.5 × a

Divide both side by 0.5

a = 4 / 0.5

a = 8 m/s²

Therefore, the same force (i.e 4 N) applied to the hockey puck will give the 0.5 kg baseball an acceleration of 8 m/s².

Answer:

(a) 14.5 m/s

(b) 9.5 m/s

Explanation:

Let the speed of the boat in the still water (i.e relative to ground) is [tex]v_0[/tex].

Given that the speed of the boat relative to water, [tex]v_r=12.0[/tex] m/s.

Speed of the water current of the river relative to the ground, [tex]u_0=2.50[/tex] m/s towards east.

(a) When the boat is heading toward the east (in the same direction of the current of the river)

The relative velocity, [tex]v_r[/tex], of the boat with respect to ground is

[tex]v_r=v_0-u_0[/tex]

[tex]\Rightarrow 12=v_0-2.5[/tex]

[tex]\Rightarrow v_0=12+2.5=14.5[/tex] m/s

Hence, the boat's speed relative to the ground when it is heading east, with the current, is 14.5 m/s.

(b) When the boat is heading toward the west (in the opposite direction of the current of the river)

The relative velocity, [tex]v_r[/tex], of the boat with respect to ground is

[tex]v_r=v_0-(-u_0)[/tex]

[tex]\Rightarrow 12=v_0+2.5[/tex]

[tex]\Rightarrow v_0=12-2.5=9.5[/tex] m/s

Hence, the boat's speed relative to the ground when it is heading west, against the current, is 9.5 m/s.

Answer:

6.6 s.

Explanation:

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

Height (h) = 215 m

Time (t) =..?

Thus, we can obtain the time taken for the ball to get to the ground by applying the following formula:

h = ½gt²

Where:

h is the height.

g is the acceleration due to gravity

t is the time to taken.

With the above formula, the time taken for the ball to get to the ground can be obtained as follow:

Height (h) = 215 m

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

Time (t) =..?

h = ½gt²

215 = ½ × 9.8 × t²

215 = 4.9 × t²

Divide both side by 4.9

215 / 4.9 = t²

Take the square root of both side.

t = √(215 / 4.9)

t = 6.6 s

Therefore, it will take 6.6 s for the ball to get to the ground.

Answer:

Explanation:is that speed is the state of moving quickly or the capacity for rapid motion; rapidity while strength is the quality or degree of being strong.

If a skier (down a straight course) is able to enter the starting gate with a speed of 1 m/sec and the average acceleration down the hill was 3 m/s², then he was moving at  31 m / s at the bottom of the course.

There are three equations of motion given by  Newton

v = u + at

S = ut + 1/2 × a × t²

v² - u² = 2 × a × s

As given in the problem, a skier (down a straight course) is able to enter the starting gate with a speed of 1 m/sec and the average acceleration down the hill was 3 m/s² .

By using the first equation of the motion,

v = u + at

v = 1 + 3 × 10

v = 31 m / s

Thus, he was moving at  31 m / s at the bottom of the course.
