Answer:

I think B but I could be wrong

Explanation:

I would say A because Newton Law of motion is you pushing force and the object pushing force back on you

A basketball sitting on the basketball court doesn’t move until something pushes it. - this provides the best evidence for Newton’s First Law of Motion. Hence, option (B) is correct.

According to Newton's first law of motion: Until and unless an external force occurs on a body, it is in a condition of rest or uniform motion in a straight line.

According to Newton's first law of motion, a body won't begin to move unless and until an outside force acts on it. When anything starts moving, it won't stop or vary its speed unless another force acts on it. The law of inertia is another name for the first law of motion.

Hence, a basketball sitting on the basketball court doesn’t move until something pushes it. This is an example of  Newton’s First Law of Motion.

Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of theparticles determines the state of matter of thesubstance. The end result of increased molecular motion is that the object expands and takes up more space.

Answer:

\( V = U + at\)

Explanation:

Given the following data;

Initial velocity = 0 (since the stone is starting from rest).

Final velocity = 32 m/s

Acceleration = g = 10 m/s²

Time = 3.2 seconds

To show that the speed of the stone when it hits the ground is 32 m/s, we would use the first equation of motion;

\( V = U + at\)

Where;

Substituting into the formula, we have;

\( 32 = 0 + 10*3.2\)

\( 32 = 0 + 32 \)

\( 32 = 32 \)

Proven: 32 m/s = 32 m/s

KE= 6,875 J.

Formula: \(KE=\frac{1}{2} mv^{2}\)

Speed(v)= 5m/s

Mass(m)= 550 kg

\(KE=\frac{1}{2} (550kg)(5m/s)^{2}\\ \\KE=(275kg)(25(m/s)^{2})\\ \\KE=6875kg*\frac{m^{2} }{s^{2} }\)

According to the definition of energy units, we can rewrite the final answer as the following:

\(KE=6875J\)

J stands for "joules", unit of energy (check the attached image).

Answer:

→Inverted image ( upside down )

→Real image ( because it is formed on the screen )

→Magified image ( image size is greater than object size)

The cooling rate of the object is 0.054.

Let's find the cooling rate (k) of an object using the given information. Ts = 10 °CTo = 110 °CT1 = 35 °Ct2 = 25 minutes. Now, the given formula is T = Ts + (To - Ts) e ^ -kt. Here, we know that the temperature drops from 110°C to 35°C, which is 75°C in 25 minutes. Now, we will substitute the values in the formula as follows:35 = 10 + (110 - 10) e ^ (-k × 25) => (35 - 10) / 100 = e ^ (-k × 25) => 25 / 100 = k × 25 => k = 0.054. Therefore, the cooling rate of the object is 0.054. Hence, option A is correct.

Which of the planets has the highest density.

Explanation:

Neptune is known as the ice planet. It has a higher density than gas giants but a lower density than rocky planets. The density of the Neptune is 1638 kg/m³.

Jupiter is known as a gas giant. Gas giants has the lowest densities. The density of Jupiter is 1326 kg/m³.

The Earth and the Mercury are rocky planets. The densities of rocky planets are more than that of the gas giants and ice giants. The density of the Earth is 5514 kg/m³ and the density of the Mercury is 5429 kg/m³.

Final answer:

On comparing the densities of the planets, the Earth has the highest density.

Thus the correct answer is option C.

Explanation:

Answer:

Newton's second law of motion is F = ma, or force is equal to mass times acceleration.

Two vectors vector a and vector b, each located in a different position in the plane, have equal magnitude and the same direction, both vectors are considered to be parallel to each other.

Two vectors are said to be parallel if and as it were in case the angle between them is degrees. Parallel vectors are too known as collinear vectors, that is two parallel vectors will be continuously parallel to the same line but they can be either within the same direction or within the exact inverse direction. The cross product of any two parallel vectors could be a zero vector. For any two parallel vectors a and b, their dot product is equal to the product of their magnitudes.

Answer:

sandy is 6 blocks north of her starting point

Explanation:

Explanation: The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces. The more particles that hit the walls, the higher the pressure.

Answer:

The answer is D

Explanation:

A must always be taller than B  for the skateboarder to have just enough energy to complete the loop.

Centripetal acceleration is a characteristic of an object's motion along a circular path. Centripetal acceleration applies to any item travelling in a circle with an acceleration vector pointing in the direction of the circle's center.

To cancel out gravitational acceleration at point  B, the skateboarder should have centripetal acceleration, that is, he should have some amount of kinetic energy.

Hence, from conservation of energy, it may be written that:

Potential energy at point A = (potential energy + kinetic energy) at point B

mgh₁ = mgh₂ + mv²/2

Hence, h₁ > h₂

That is, Height of A > height of B

Hence,  A must always be taller than B  for the skateboarder to have just enough energy to complete the loop.

The characteristics of the image are  virtual, upright, and magnified.

When an object is placed between 2f  and f  ( 2f > x₀ > f) of a concave lens, the resulting image formed will be virtual, upright, and magnified.

From the given position of the object which is described the by the equation given, we can explain it as follows;

2f > x₀ > f

where;

From the ray diagram, the object is thick in colour meaning it is real, the image formed is faint in colour meaning it is virtual.

Also the height of the image formed is longer than that of the object meaning the image is magnified.

Finally, the image formed is upright while the object is inverted downwards.
