In order to get the ketchup in a bottle to come out easier, you hit the bottom of the bottle while it is inverted (upside down). Which of Newton's laws best describes why this works?

Answer:

We can use Coulomb's law to solve this problem:

F = k * q1 * q2 / r^2

where F is the force between the two charges, k is Coulomb's constant (k = 9 x 10^9 N m^2 / C^2), q1 and q2 are the magnitudes of the charges, and r is the distance between them.

We know the force F, the distance r, and the magnitude of one of the charges q1. We can rearrange the equation to solve for the magnitude of the other charge q2:

q2 = F * r^2 / (k * q1)

Substituting the values we have:

q2 = (250 N) * (0.15 m)^2 / (9 x 10^9 N m^2 / C^2 * 6.5 x 10^-5 C)

Simplifying:

q2 = 8.65 x 10^5 C

Therefore, the magnitude of the other charge is 8.65 x 10^5 C.

Answer:

Density= 2.78 g/cm³

Relative density=2.8

Explanation:

To calculate the density of the cube we have to use the formula ρ=mass/volume

ρ stands for density.

So now we don't have the volume of the cube and to find the volume of the cube we have to use the formula a³

3³= 9 cm³

Now plug in the values. ρ= 25 g/9 cm³

ρ= 2.78 g/cm³

To find the relative density, we have to use the formula ρsample/ρH20

The sample means the density of the substance earlier. We do not know the density of water but it is constant at 997 kg/m³.

Now we have to make the units same so you change the unit of the density of cube to kg/m³

So, 25/1000= 0.025 kg

9/100×100×100 (because cm³ which means that there should be 3 meters to change the unit and to conver cm to meter we need to divide by 100 so 9cm/100, 9cm²/100×100, 9cm³/100×100×100)

=0.000009 m³

The new density= 0.025 kg/ 0.000009 m³

= 2777.78 kg/m³

Now plug the values into the formula:

relative density= 2.777.78 kg/m³ / 997 kg/m³

=2.8

There is no unit since kg/m³ and kg/m³ cancels

When a wire moves through a magnetic field, an electric current is produced in the wire, and the phenomenon to which this is referring is called electromagnetic induction, as presented in option A.

A magnetic field is a region in space where a magnetic force can be detected, so when a wire moves through a magnetic field, the magnetic force exerted on the wire generates a voltage, and the voltage creates an electric current in the wire. This electromagnetic induction phenomenon occurs because of the movement of charged particles within the wire, and this phenomenon can be explained by Faraday's Law of Electromagnetic Induction.

Answer: Force = 870 N  

Explanation:

acceleration = a = (final velocity - initial velocity) / time elapsed

a = (0-30)/.005 = -6000 m/s2 (negative sign means the ball is slowing down)

Force = F = mass x acceleration = ma

F = (0.145 kg)(6000 m/s2) = 870 N away from the player throwing the ball

The magnitude of the force on the player catching the ball is equal, 870N.  The mitt acts on the ball with an equal and opposite force (Newton's 3rd Law of Motion)

In conclusion, the magnetic flux through the center of a solenoid with a radius of 2.10 cm and a magnetic field of 0.52 T is 0.00072 Wb.

To determine the magnetic flux through the center of a solenoid with a radius of 2.10 cm and a magnetic field of 0.52 T, we need to use the formula for magnetic flux, which is Φ = B × A, where B is the magnetic field and A is the area of the surface perpendicular to the field.
Since the solenoid has a cylindrical shape, we can use the formula for the area of a circle, which is A = πr^2, where r is the radius of the circle. Therefore, the area of the solenoid is A = π(0.021)^2 = 0.001385 m^2.
Substituting the values of B and A into the formula for magnetic flux, we get Φ = (0.52 T) × (0.001385 m^2) = 0.00072 Wb.
Therefore, the magnetic flux through the center of the solenoid is 0.00072 Wb.

Answer:

gₓ = 23.1 m/s²

Explanation:

The weight of an object is on the surface of earth is given by the following formula:

\(W = mg\)

where,

W = Weight of the object on surface of earth

m = mass of object

g = acceleration due to gravity on the surface of earth = strength of gravity on the surface of earth

Similarly, the weight of the object on Jupiter will be given as:

\(W_{x} = mg_{x}\)

where,

Wₓ = Weight of the object on surface of Jupiter = 34.665 N

m = mass of object = 1.5 kg

gₓ = acceleration due to gravity on the surface of Jupiter = strength of gravity on the surface of Jupiter = ?

Therefore,

\(34.65 N = (1.5 kg)g_{x}\)

\(g_{x} = \frac{34.65 N}{1.5 kg}\)

gₓ = 23.1 m/s²

The type of material with the highest condensation temperature in the planetary system is B. rocks and dust grains

Condensation temperature refers to the temperature at which a substance transitions from a gaseous state to a solid or liquid state as the result of cooling. Different materials have different condensation temperatures, depending on their chemical composition and physical properties.

In the context of the planetary system, during the formation of planets and other celestial bodies, there is a process known as accretion where small solid particles collide and stick together, gradually forming larger objects. These solid particles are primarily composed of rocks and dust grains, which have relatively high condensation temperatures compared to gases.

Gases such as nitrogen gas (option A), methane, ammonia, and water vapor (option C), as well as hydrogen (option D), have lower condensation temperatures compared to rocks and dust grains. They typically exist in a gaseous state at temperatures found in the outer regions of planetary systems. However, as we move closer to the central star or a forming planet, where temperatures are higher, these gases can condense and form volatile compounds or liquids.

Understanding the condensation temperatures of different materials helps in explaining the formation and composition of planetary systems, as it provides insights into the distribution and abundance of different substances based on their physical properties. Therefore, Option B is correct.

No net force is experienced. To find the magnitude of the net gravitational force exerted by the two larger masses on the 60.6 kg mass, we can use the equation for gravitational force.

Gravitational force equation:

F = G * (m1 * m2) / r^2

Where F is the gravitational force, G is the universal gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them.

In this case, m1 = 232 kg, m2 = 538 kg and r = 0.342 m.

So, F = G * (232 kg * 538 kg) / (0.342 m)^2

Plugging in the values, we get:

F = 6.672 x 10^-11 N*(m^2)/(kg^2) * (232 kg * 538 kg) / (0.342 m)^2

The magnitude of the net gravitational force exerted by the two larger masses on the 60.6 kg mass is 0.092 N.

To find the distance at which the 60.6 kg mass experiences a net force of zero, we can use the equation for the gravitational force between two masses. Since the force is inversely proportional to the square of the distance between the masses, we can set the force to zero and solve for the distance.

F = G * (232 kg * 60.6 kg) / (r)^2 = 0

r = √((232 kg * 60.6 kg) / (G))

r = √((232 * 60.6) / (6.672 * 10^-11))

r = 2.36*10^-5 m

At this distance, the 60.6 kg mass experiences no net force from the two larger masses, as the gravitational force exerted by the 232 kg mass balances out the gravitational force exerted by the 538 kg mass.

The phenomenon that occurs at the surface of the paper is called diffuse reflection or scattering.

When a student looks into a plane mirror, she sees a virtual image of herself because the mirror reflects the light rays coming from her body and forms an image behind the mirror. Since the image is formed by the reflected light, it is a virtual image, which means that the light rays do not actually converge at the position of the image.

On the other hand, when the student looks into a sheet of paper, no such image forms because the paper does not reflect enough light to form a clear image. The surface of the paper appears diffused and irregular due to the scattering of light by the surface irregularities and fibers of the paper.

The phenomenon that occurs at the surface of the paper is called diffuse reflection or scattering. When light falls on a rough or irregular surface, it is scattered in different directions instead of reflecting in a single direction, as in the case of a mirror. The scattered light produces a diffused image of the object, which does not have a well-defined shape or position. This is why the student cannot see a clear image of herself when looking at the paper.
