How are distance and displacement the same?

2 answers:

6 0

Distance and displacement are two quantities that may seem to mean the same thing yet have distinctly different definitions and meanings. Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.

In the case of straight line, when the object is not repeating it's path then distance and displacement would be same.

The drawing shows a side view of a swimming pool. The pressure at the surface of the water is atmospheric pressure. The pressure

Nikitich [7]

Answer:

A) To true. he pressure at the bottom of the pool decreases by exactly the same amount as the atmospheric pressure decreases

Explanation:

Let us propose the solution of this problem before seeing the final statements. The pressure increases with the depth of raposin due to the weight of water that is above the person and also the pressure exerted by the atmosphere on the entire pool, the equation describing this process is

P = $P_{atm}$ + ρ g y

Where $P_{atm}$ is the atmospheric pressure, ρ the water density, and 'y' the depth measured from the surface.

Let's examine this equation in we see that the total pressure is directly proportional to the atmospheric pressure and depth

Now we can examine the claims

A) To true. State agreement or with the equation above

B) False. Pressure changes with atmospheric pressure

C) False. It's the opposite

D) False. They are directly proportional

A student wished to add a new experiment to Chapter 2 by investigating whether the mass of water changes when it is heated. The

Valentin [98]

Answer:

mass conservation is valid for all closed system where the mass will remain in the system always

Explanation:

Conservation of mass is applicable everywhere in classical physics

Here we can also apply mass conservation as we know that the initially the beaker and its water content is having total mass of 109.44 g

$m_1 = 109.44 g$

now when we heated it to higher temperature then its total mass will be lesser than the initial mass this is because some of the water may evaporate from the system.

Here if we repeat the same experiment with closed boundary then we can see that total mass will be conserved

So here mass conservation is valid for all closed system where the mass will remain in the system always

The four wheels of a car are connected to the car's body by spring assemblies that let the wheels move up and down over bumps an

maksim [4K]

Answer:

The approximate spring constant is $k = 55533.33 \ N/m$

Explanation:

From the question we are told that

The mass of the person is $m = 68 \ kg$

The dip of the car is $x = 1.2 \ cm = 0.012 \ m$

Generally according to hooks law

$F = k * x$

here the force F is the weight of the person which is mathematically represented as

$F = m * g$

=> $m * g = k * x$

=> $k = \frac{m * g }{x }$

=> $k = \frac{68 * 9.8}{ 0.012}$

=> $k = 55533.33 \ N/m$

A food processor draws 8.47 A of current when connected to a potential difference of 110 V.

Andreyy89

Answer:

27.95[kW*min]

Explanation:

We must remember that the power can be determined by the product of the current by the voltage.

$P=V*I$

where:

P = power [W]

V = voltage [volt]

I = amperage [Amp]

Now replacing:

$P=110*8.47\\P=931.7[W]$

Now the energy consumed can be obtained mediate the multiplication of the power by the amount of time in operation, we must obtain an amount in Kw per hour [kW-min]

$Energy = 931.7[kW]*30[days]*10[\frac{min}{1day} ]=279510[W*min]or 27.95[kW*min]$

Two neutral metal spheres on wood stands are touching. A negatively charged rod is held directly above the top of the left spher

Paha777 [63]

Answer:

The right sphere is negatively charged, the left sphere is charged positively.

Explanation:

When a negatively charged rod is held above the top of left sphere, the rod will attract positive charges and repel negative charges. As the sphere are initially touching each other so positive charges from the both spheres will moves toward the rod. When we separate the spheres positive charges from right sphere have already moved toward the rod i.e. left sphere, creating a deficiency of positive charges in the right sphere and excessiveness of positive charges in left sphere , hence the right sphere will remain negatively charged and left sphere will remain positively charged.
