Any object which is in state or rest is made to change its by applying the external force. An object is made to move or stay still due to its inertia.

Mass is the measure of inertia . Greater the mass, greater will be the inertia.

Inertia is the opposition caused to the motion of an object whether it is still or moving. It is a tendency to do nothing or remain unchanged.

Hence, Inertia causes an object to move or stay still.

Objects move or stay still based on Newton's first law of motion or the law of inertia, which states that an object will continue its current state of rest or constant motion unless an external force acts upon it.

What causes objects to move or stay still can be explained by Newton's first law of motion, also known as the law of inertia. This law states that every object will continue to be in a state of rest or move at a constant speed in a straight line unless it is compelled to change by an outside force. For example, if you slide a book on a table, it eventually stops because of the friction (an outside force) between the book and the table.

Similarly, an object moving in an elliptical path, such as a planet, must be subjected to a constant force that keeps changing its direction. Newton proposed this force to be gravity. So, if you throw a ball (a small scale example), it eventually drops to the ground because of the gravitational pull of the earth.

Therefore, without an external force, a stationary object stays put, and a moving object keeps moving at the same speed and in the same direction.

Explanation:

When the object hits the water, it's not adding weight to the object, but is changing the force of the waves in the water. They wouldn't be balanced and this wouldn't determine if the object would stop. However, with more informational variables with precise measurements the answer may alter.

here we can use energy conservation

like initial kinetic + potential energy is always conserved and it will be same at all points

so we can say

[tex]KE_i + PE_i = KE_f + PE_f[/tex]

[tex]\frac{1}{2}mv_i^2 + mgh_1 = \frac{1}{2}mv_f^2 + mgh_2[/tex]

now we can plug in all the given values in it

[tex]v_i = 0[/tex]

[tex]h_1 = 443 m[/tex]

[tex]h_2 = 221 m[/tex]

[tex]\frac{1}{2}m*0 + m*9.8*443 = \frac{1}{2} m*v_f^2 + m*9.8*221[/tex]

now divide whole equation by mass "m"

[tex]9.8*443 = \frac{1}{2} v_f^2 + 9.8*221[/tex]

[tex]2175.6 = \frac{1}{2}v_f^2[/tex]

[tex]v_f = 65.96 m/s[/tex]

so final speed will be 65.96 m/s

When Amelia apply brakes the car will start reducing its speed and then finally stop

So here as per Newton's First law we can say all object continue its state of motion until and unless some unbalanced external force act upon its.

This property is due to inertia of the object which is the property of mass. Here inertia is the property which resist the change in state of motion of an object.

If brakes are applied and an object stops after some time (let say t = 5 s) and on applying brakes other object stop in other time (let say t = 10 s) then if other object took longer time to stop then it means its inertia will be more.

So its all depends on inertia of object that how much time it will take to stop after applying brakes

The different colors in the sky are caused by the scattering of sunlight in Earth's atmosphere. Blue light scatters more efficiently than other colors, resulting in the blue color of the sky.

The different colors that appear in the sky are caused by the scattering of sunlight. When sunlight enters Earth's atmosphere, it scatters from the molecules of air. The small size of the air molecules causes blue light to scatter more efficiently than other colors, such as greens, yellows, and reds. Therefore, the blue light is scattered all over the sky, resulting in the blue color of the sky.

Answer:imagine Bohr coming up to you and saying i have 2 atoms; it sticks together and becomes a compound.

Explanation:

Answer: The work OUTPUT of a simple machine can never exceed the work INPUT because FRICTION uses some of the work.

Explanation:

This concept is related to ideal machines and efficiency.

Only ideal machines can convert all the work input into useful work (work ouput).

The efficiency is a concept that tells you the proportion of input work that is transformed into output work.

         Efficiency = (output work / input work) × 100

Ideal machines, those where friction does not exist, have a 100% efficiency, and so ideal machines convert all the input work into useful output work.

Real machines have a efficiency less than 100%. Friction lowers the efficiency and the work outpu is less than the work input, because friction uses work which is converted, mostly, into heat energy or sound energy.

here we need to write the two components of the displacement and then we need to add them

first displacement is given as

[tex]d_1 = 75 km[/tex] 30 degree West of North

[tex]d_1 = - 75 sin30 \hat i + 75 cos 30 \hat j[/tex]

[tex]d_1 = - 37.5 \hat i + 64.9\hat j[/tex]

Other displacement is given as

[tex]d_2 = 155 km[/tex] 60 degree due East of North

[tex]d_2 = 155 sin60 \hat i + 155 cos60 \hat j[/tex]

[tex]d_2 = 134.2 \hat i + 77.5 \hat j[/tex]

now we need to find the net displacement

[tex]d = d_1 + d_2[/tex]

[tex]d = (-37.5 + 134.2)\hat i + (64.9 + 77.5)\hat j[/tex]

[tex]d = 96.7\hat i + 142.4\hat j[/tex]

so it is given as

[tex]d = \sqrt{96.7^2 + 142.4^2}[/tex]

[tex]d = 172.1 km[/tex]

and its direction is given as

[tex]\theta = tan^{-1}\frac{96.7}{142.4} = 34.1 degree[/tex]

so it will displace by 172.1 km at 34.1 Degree East of North

initial speed by which Hilary is walking = 1.3 m/s

Now the rate of increase in her speed that is her acceleration is given by

[tex]a = 0.090 m/s^2[/tex]

now we need to find her final speed after t = 10 s

so here we can use the kinematics equation in order to find the final speed

[tex]v_f = v_i + at[/tex]

now plug in all data in the above equation

[tex]v_f = 1.3 + (0.090 * 10)[/tex]

[tex]v_f = 1.3 + 0.90[/tex]

[tex]v_f = 2.2 m/s[/tex]

Answer:

[tex]T_2 = 1.40 hours[/tex]

Explanation:

As per kepler's law of time period we know that

square of time period is proportional to the cube of the distance

so here we can say

[tex]\frac{T_1^2}{T_2^2} = \frac{r_1^3}{r_2^3}[/tex]

so we know that

for moon

[tex]T_1 = 27.4 days[/tex]

[tex]r_1 = 384,400 km[/tex]

[tex]r_2 = 6370 km[/tex]

now from above formula we have

[tex]\frac{27.4^2}{T_2^2} = \frac{384,400^3}{6370^3}[/tex]

[tex]T_2 = 0.058 days[/tex]

[tex]T_2 = 1.40 hours[/tex]

Using Kepler's third law and the period of the Moon, we find that an artificial satellite very close to Earth has a period of approximately 1.41 hours. This involves comparing the orbital radii and periods using the proportional relationship given by Kepler's law. Substituting values and simplifying yields the final period.

To determine the period of an artificial satellite orbiting very near the Earth’s surface using Kepler’s laws, we will use Kepler's third law, which states that the square of the orbital period (T) is proportional to the cube of the average orbital radius (r). Given the following:

Now, add the radius of the Earth to get the orbital radius of the satellite, r2 = rE + 0 = 6.38 × 106 m. According to Kepler’s third law ([tex]T_2[/tex] ∝ [tex]r_3[/tex]), we have:

Substitute the known values:

Simplifying the right side:

Taking the square root of both sides to solve for [tex]T_2[/tex] :

Converting days to hours (1 day = 24 hours):

Therefore, the period of an artificial satellite orbiting very near the Earth’s surface is approximately 1.41 hours.

The friction force is equal to 120 N. This is based on Newton's First Law. The friction force balances the pushing force, thus keeping the box stationary.

When you push on a large box with 120 N of force and it does not move, it means that the friction force opposing your push is equal to the pushing force. This is based on Newton's First Law of Motion which states that an object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an unbalanced external force. Friction is the resisting force that occurs between two surfaces in contact when one or both of the surfaces are moved or attempt to move. In this case, the friction force is 120 N because it precisely offsets the applied force, keeping the box stationary.

Zero latitude gets the most direct sun all year around. That's the equator.

The picture you attached has nothing to do with this question.

The Equator (0 degrees latitude) receives the most direct rays of the sun year-round due to being at the midpoint of the Earth's surface. As we move towards poles, the sunlight becomes less direct.

The latitude that receives the most direct rays of the sun year-round is 0 degrees, also known as the Equator. The rays of the sun hit the equator directly because it is the midpoint of the Earth's surface. As you move away from the Equator, either towards the North or South Pole (which are 90 degrees latitude), the sun's rays hit the Earth's surface at increasingly oblique angles, resulting in less direct sunlight. Hence, options B, C, and D (30 degrees, 60 degrees, 90 degrees respectively) receive less direct sunlight compared to the Equator (0 degrees).

Answer:

a) Acceleration, a = -u/9, where u is the initial velocity

b) Acceleration = 0.741 m/s², Initial velocity = 6.67 m/s

Explanation:

 We have equation of motion, v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.

a)  We have v = 0 m/s, t = 9 s

 So,    0 = u + a x 9

      Acceleration, a = -u/9, where u is the initial velocity

b) We have equation of motion , [tex]s= ut+\frac{1}{2} at^2[/tex], s is the displacement, u is the initial velocity, a is the acceleration and t is the time.

 s = 30 m , u = -9a, t =9 s

 So,  [tex]30= -9a*9+\frac{1}{2} *a*9^2\\ \\ 30=-40.5a\\ \\ a=-0.741m/s^2[/tex]

u = -9a = 6.67 m/s

So acceleration = 0.741 m/s², Initial velocity = 6.67 m/s

Final answer:

The answer explains how to calculate the acceleration of the puck given the distance it traveled and the time taken. It further details how to find the initial velocity of the puck using the acceleration obtained earlier.

Explanation:

A. To determine the acceleration of the puck, we can use the equation:

a = 2x / t^2

Substitute the values given: x = 30m and t = 9s.

b. To find the initial velocity of the puck, we first calculate the acceleration using the formula a = Δv / t, where Δv = final velocity - initial velocity.

Then, knowing the acceleration from part (a), we can calculate the initial velocity using the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time taken.

Sound waves  are a change of pressure that moves through matter. (C)

Trade winds near equator blows in curve path instead of straight path. This is because of earth rotation. This effect of earth rotation that cause wind to move in curve motion is called Coriolis effect. These kind of wind blows at the northeast of the North hemisphere and southeast of the South hemisphere. The trade wind are warm and it blows due to rising of hot air from equator.

Final answer:

Trade winds don't blow straight toward the equator because the Coriolis effect causes deflection to the right in the northern hemisphere, forming northeast trade winds, and to the left in the southern hemisphere, forming southeast trade winds.

Explanation:

The trade winds don't blow straight toward the equator due to the influence of the Coriolis effect, which is caused by the rotation of the Earth. In the northern hemisphere, air moving toward the equator is deflected to the right, creating the northeast trade winds. Conversely, in the southern hemisphere, air moving toward the equator is deflected to the left, resulting in the southeast trade winds. These winds converge near the equator in the Intertropical Convergence Zone (ITCZ), leading to very wet conditions and the formation of the world's great rainforests.

Explanation:

It is given that,

An amateur player is about to throw a dart with an initial velocity of 15 meters/second onto a dartboard.

Dashboard is placed at a distance of 2.7 meters.

Calculating time from velocity and distance i.e. [tex]t=\dfrac{d}{s}=\dfrac{2.7}{15}\ s=0.18\ s[/tex]

Using second equation of motion for finding vertical distance :

[tex]s=ut+0.5gt^2[/tex]

Here, u = 0 (for vertical velocity )

[tex]s=0.5gt^2[/tex]  

[tex]s=0.5\times 10\times (0.18)^2[/tex]        

s = 0.162 meters

or s = 0.16 meters

Hence, the vertical distance by which the player will miss the target if he throws the dart horizontally, in line with the dartboard is 0.16 meters.

The potential energy gained by driving the car from sea level to Nu’uanu Pali lookout is approximately 3,589,260 joules.

Explanation:

To calculate the potential energy gained by driving your car from sea level up to the Nu’uanu Pali lookout, we can use the formula: PE = mgh, where m is the mass of the car, g is the acceleration due to gravity, and h is the change in height. In this case, the mass is 1000 kg, g is approximately 9.81 m/s², and h is 366 m. Plugging in the values, we get:

PE = 1000 kg * 9.81 m/s² * 366 m = 3,589,260 joules

So, driving your car up to the Nu’uanu Pali lookout increases its potential energy by approximately 3,589,260 joules.
