Answer:

4. A 10-kilogram sled at rest

Explanation:

The object with most inertia is a 10-kilogram sled at rest.

Inertia is the tendency of a body to remain at rest or continue with uniform motion.

Now, this is better highlighted by Newton's first law of motion which states that "an object will remain in a state of rest or of uniform motion unless it is acted upon by an external force".

The more the mass of a body, the greater its inertia
So, the choice with the most mass will have the highest inertia and will be the most reluctant to change position.

2) If the current in any circuit reach to infinity then its resistance becomes

sveta [45]

Given that,

Current = ∞

We know that,

Ohm's law :

Ohm's law is defined as,

The voltage of the circuit is directly proportional to the current of the circuit.

$V\propto I$

Or,

The voltage of the circuit is equal to the product of current and resistance.

In mathematically,

$V=IR$

Where, V = voltage

I = current

R = resistance

According to ohm's law,

The current in the circuit is

$I=\dfrac{V}{R}$

If the current is very less then the resistance will be infinity.

If the is reach to infinity then the resistance will be very low.

Hence, The resistance becomes very low.

During heavy rain, a section of a mountainside measuring 2.5 km horizontally, 0.80 km up along the slope, and 2.0 m deep slips i

Crank

Answer:

The mass of the mud is 3040000 kg.

Explanation:

Given that,

length = 2.5 km

Width = 0.80 km

Height = 2.0 m

Length of valley = 0.40 km

Width of valley = 0.40 km

Density = 1900 Kg/m³

Area = 4.0 m²

We need to calculate the mass of the mud

Using formula of density

$\rho=\dfrac{m}{V}$

$m=\rho\times V$

Where, V = volume of mud

$\rho$ = density of mud

Put the value into the formula

$m=1900\times4.0\times0.40\times10^{3}$

$m =3040000\ kg$

Hence, The mass of the mud is 3040000 kg.

When sound is created it travels to the car through a

Rasek [7]

A sound wave is a longitudinal wave caused by vibrations and carried through a substance. The particles of the substance, such as air particles, vibrate back and forth along the path that the sound waves travel. Sound is transmitted through the vibrations and collisions of the particles.

This could maybe help you with your answer.
