How are passengers affected when a moving bus is stopped suddenly? Explain with reason.​

Physics
1 answer:
Mademuasel [1]2 years ago
5 0

Answer:

When a moving bus stops suddenly, the passenger are pushed forward because of the inertia of the passengers. ... Because the lower part of the body comes to rest with the bus while the upper part tends to continue its motion due to inertia.

Explanation :

The passengers in a bus tend to fall backward when it starts suddenly due to inertia as the passengers tend to remain in the state of rest while the bus starts to move. When the bus stops suddenly, people fall forward because their inertia as they are in state of motion even when the bus has come to rest.

Hope this helps!! <3

If a satellite weighs 321 lb. on the earth's surface (R = 4,000 miles), how much does it weigh 12,000 miles above the surface? (
Sever21 [200]

The gravitational force between the Earth and the satellite (its "weight") is inversely proportional to the distance between the centers of both objects.

On the surface, their centers are separated by 1 Earth radius.

12,000 miles above the surface, they're separated by 4 Earth radiii.

(4/1) = 4

So after the move, the satellite's weight is (1/4²) = 1/16 of its surface weight.

(321 lb) / (16) = (20 and a hair) lb

The correct choice from the given list is " <em>>20 lb "</em> .

The current supplied by a battery as a function of time is ) -(0.64 A)e-/(6.0 hr). What is the total number of electrons transpo
Paha777 [63]

Answer:

The total number of electrons is 8.6\times10^{22}

(3) is correct option.

Explanation:

Given that,

The current equation is

I=0.64 e^{\dfrac{-t}{6.0 hr}}

We know that,

The formula of charge

q=\int_{0}^{\infty}{I dt}

q=\int_{0}^{\infty}{0.64 e^{\dfrac{-t}{6.0 hr}}dt

q=0.64\int_{0}^{\infty}{e^{\dfrac{-t}{6.0 hr}}dt

q=0.64\int_{0}^{\infty}{e^{\dfrac{-t}{21600}}dt

q=0.64(21600e^{\dfrac{-t}{21600}})_{0}^{\infty}

q=0.64(0-21600)

q=0.64\times21600

q=13824\ C

We need to calculate the number of electron

Using formula of charge

q=ne

n=\dfrac{q}{e}

n=\dfrac{13824}{1.6\times10^{-19}}

n=8.6\times10^{22}

Hence, The total number of electrons is 8.6\times10^{22}
