In terms of impulse and momentum, why are air bags in automobiles a good idea

1 answer:

5 0

During a car crash, the car decelerates extremely rapidly, so inertia causes you to move forward quickly. If there wasn't an airbag to slow you down, you might fly out the windshield.
The air bag increases impulse by increasing the time during which a force acts on you (impulse=force*time). This decreases your forward momentum, so you'll have a better chance of surviving.

As capacitor was discharging, what did you observe about q on its plates and the motion of charges in the external circuit?

liubo4ka [24]

As capacitor was discharging, The charge on the plate got reversed and the motion of charge is opposite to the flow of current.

The charging contemporary asymptotically processes 0 as the capacitor becomes charged up to the battery voltage.

The capacitor is completely charged when the voltage of the electricity supply is equal to that at the capacitor terminals. that is referred to as capacitor charging; and the charging segment is over when modern-day stops flowing thru the electrical circuit.

A capacitor can be slowly charged to the important voltage and then discharged quick to provide the power wanted. it's far even viable to charge several capacitors to a positive voltage and then discharge them in any such way as to get extra voltage out of the gadget than became installed.

What happened to the weight of an object when it is taken from Earth to the Moon? why?

Sholpan [36]

Answer:

the weight of the object decreases when it is taken from the Earth to the Moon

Explanation:

The weight of an object is defined as the product of the mass of the object with the acceleration due to gravity of the Planet.

$W =mg$

where,

W = weight of the object

m = mass of the object

g = acceleration due to gravity on the planet

The mass of an object remains constant everywhere in the universe. Therefore, the weight is directly proportional to the value of acceleration due to gravity.

The value of acceleration due to gravity on the Moon is lesser than its value on the Earth.

Hence, the weight of the object decreases when it is taken from the Earth to the Moon

Which properties define light as a wave?

Naddik [55]

Properties that define the light is a wave are

1. Speed : speed of light is 300,000 Km /s, It is most fundamenta property of light to define light is a wave

2. Reflection: Light particles or photons reflect off the particles or masses are continue to travel at the same speed.

3. colour
