Which statement accurately describes static electricity?

Answer:

polar-molecule

Explanation:

Answer:

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed

Explanation:

Answer:

Current, I = 5A.

Voltage, V = 60V.

Explanation:

In part 1;

We were given the following data:

Resistance = 24 ohm

Voltage = 120V

To find the current,

According to ohm's law which states that, the current flowing through a conductor is directly proportional to the amount of potential voltage across its terminal and inversely proportional to the opposition to the flow of current (resistance) of the conductor.

Mathematically,

[tex] V = IR[/tex]

Where, V represents voltage measured in volts (v).

I represent current measured in amperes (A).

R represent resistance measured in ohms.

[tex]I = \frac{V}{R}[/tex]

Substituting into the equation, we have;

[tex]I = \frac{120}{24}[/tex]

I = 5amp

For part 2.

Given the following data

Current = 6

Resistance = 10ohms

Velocity =?

[tex] V = IR[/tex]

[tex] V = 6 * 10[/tex]

V = 60V

Answer:

the answer is 19 ,30 (second) times 0.5= 15

15+4= 19

After Paco drives his scoter west with an initial velocity of 4 m/s and then accelerates at 0.5 m/s² for 30 s, his final velocity is 19 m/s, so the correct option is the fourth.  

The final velocity of Paco can be calculated with the following equation:

[tex] v_{f} = v_{i} + at [/tex]

Where:

[tex] v_{f}[/tex]: is the final velocity =?

[tex]v_{i}[/tex]: is the initial velocity = 4 m/s

a: is the acceleration = 0.5 m/s²

t: is the time 30 s

Hence, the final velocity is:

[tex] v_{f} = 4 m/s + 0.5 m/s^{2}*30 s = 19 m/s [/tex]

Therefore, the correct option is 19 m/s.

Answer: liquids take the shape of the container they are in, but have definite volume. like liquids the shape of a gas changes with the container. unlike liquids the volume of a gas changes depending on the container it is in

Explanation:

Answer:

liquids flow freely, they take the shape of the container they are in, but have a definite volume. Like liquids, the shape of a gas changes with the container. This is because the atoms in a gas move rapidly and freely to fill any available space. Unlike liquids, the volume of a gas changes depending on the container it

Answer:

Newton (N)

Explanation:

A newton is the unit of measurement for force

Answer:

The net force is 10 N.

Explanation:

A "net force" occurs when a particular object accelerates. It refers to the total number of forces that act on an object.

The boy pulling the cart and the other pushing it do their actions in the same direction. The force of pulling is 6 N while the force of pushing is 4 N. This means that the total force will not be cancelled.

To get the net force, add both forces since they are in the same direction (east).

Net force = 6 N + 4 N

Net force = 10 N (Newtons)

Answer: Lightning is seen before thunder is heard" is correct about thunderstorms

Explanation:

A "thunderstorm" is a disturbance in weather that is related with lightning, dense clouds, heavy rain, hail or thunder. During a thunderstorm, lightning is always seen before thunder because the speed at which the light travels is faster than that of sound's speed.

Also, thunder's noise could be heard up to 10 km away from lightning flash. The thunder sound lasts for a few seconds. The thunder makes noise because of the rapid and fast expansion of the heating of the air.

Answer:

Melting point

Explanation:

when a solid turns to a liquid, it is melting

Answer:

The pressure of the air molecules inside the pen cap increases and the volume occupied by the air decreases such that the combined volume occupied by the pen cap and the air volume reduces while the combined mass of the pen cap and the air molecules remain the same

Given that density = The mass/Volume, we have that the density varies inversely as the volume, and as the volume reduces, the density increases

Upon squeezing, therefore, as the new combined density of the pen cap and the air molecules rises to more than the density of the water in the bottle, then, the pen cap air molecule is relatively more denser than the water, which will result in the pen cap sinking to the bottom of the bottle

Explanation:

Use the formula for momentum:  Momentum = (mass) x (speed)

2.67 x 10⁴ kg-m/s  =  (mass) x (8.9 m/s)

Mass  =  (2.67 x 10⁴ kg-m/s) / (8.9 m/s)

Mass  =  3,000 kilograms

That's 3 metric tons.  On Earth, it weighs 6,614 pounds, or 3.3 US tons.

Answer:

B) 30 mph northwest

Explanation: Vector quantities have both direction and magnitude. In this case the direction is northwest, and magnitude is 30 mph.

The following is a vector quantity, 30 mph northwest. Option B is correct.

A vector quantity is a physical quantity that has both magnitude and direction. Examples of vector quantities include displacement, velocity, acceleration, force, and momentum.

In contrast, a scalar quantity is a physical quantity that has only magnitude and no direction associated with it. Examples of scalar quantities include speed, distance, mass, temperature, and time.

Here,
A vector quantity is a physical quantity that has both magnitude and direction. In this case, the magnitude is 30 mph and the direction is northwest, which makes it a vector quantity.

Option A is a scalar quantity because it only has a magnitude, but no direction associated with it. Option C is also a vector quantity because it has both magnitude and direction, but it is not given a direction in the question. Option D is a scalar quantity because it only has a magnitude.

Thus, the following is a vector quantity, 30 mph northwest. Option B is correct.

Answer:

Explanation: I think its D

Answer:

weight of two people

Explanation:

Suppose two people are walking and among the two people, if one is heavier than the other, then the one weighing heavier will walk slower because the acceleration of the person weighing lighter is greater.

2nd Law: F=ma

a= change in velocity/time

a=F/m

say both objects must accelerate at a=2 m/s^2

object A is a wood plank, which is roughly 10 kg

object B is my metal ball, which has a mass of 100kg

now, solving for F applied to both objects

Fwood=(10kg)(2 m/s2)= 20 N

Fmetal=(100kg)(2 m/s2)= 200 N

the F needed to move the metal ball is 10 times greater than the F needed to move the wood plank. Hope this helped, I'm about to go fail my physics exam :)

Answer:

They both arrive at 1:00 PM

Explanation:

Amount Davien has to drive : 40km

Amount Jackson has to drive = 50km

Davien moves at 40km/h,

Therefore, it only takes Davien 1 hour to get there.

12:00 PM + 1 hour = 1:00 PM

Jackson moves 100km/h

He needs to drive 50 min, so 50/100 = 1/2

It takes him half an hour, or 30minutes

If he leaves at 12:30, then he gets there at 1:00 PM

Answer:

The net acceleration of the boat is approximately 6.12 m/s² downwards

Explanation:

The buoyant or lifting force applied to the boat = 790 N

The mass of the boat lifted by the buoyant force = 214 kg

The force applied to a body is defined as the product of the mass and the acceleration of the body. Therefore, the buoyant force, F, acting on the boat can be presented as follows;

Fₐ = F - W

The weight of the boat = 214 × 9.81 = 2099.34 N

Therefore;

Fₐ = 790 - 2099.34  = -1309.34 N

Fₐ = Mass of the boat × The acceleration of the boat

Given that the buoyant force, Fₐ, is the net force acting on the boat, we have;

F = Mass of the boat × The net acceleration of the boat

F = -1309.34 N =  214 kg × The net acceleration of the boat

∴ The net acceleration of the boat = -1309.34 N/(214 kg) ≈ -6.12 m/s²

The net acceleration of the boat ≈ 6.12 m/s² downwards

The boat's  net acceleration is -6.12 m/s²

Given that:

Buoyant force = 790 N, mass (m) = 214 kg, acceleration due to gravity (g) = 9.81 m/s²

Net force = Buoyant force - mg = 790 - (214 * 9.81) = -1309.34 N

Net acceleration = Net force / mass

Net acceleration = -1309.34 N / 214 kg = -6.12 m/s²

The boat's  net acceleration is -6.12 m/s²
