How does a seal belt help prevent injuries by applying a for

Answers

A seat* belt can help prevent major injuries from car crashes because it can buckle people down safely. If a car crashed into the car and you were in the front seat without a seat belt, you could catapult straight out the window. With a seatbelt on, you will be restrained and fastened to the chair and have some not major injuries.

A seat belt helps to prevent injury in the event of a car crash by reducing the velocity of a body as it experiences a sudden decrease in speed. Due to the body's inertia, which is its 'resistance to a change in speed or direction of travel', a passenger in a vehicle will want to continue travelling forwards once the car has reached a sudden stop. If the vehicle is travelling at 50mph and crashes into a brick wall, instantly reducing its velocity to zero, the passenger will continue moving forwards at 50mph unless there is something in front of them to create a 'stopping force'. This is because the velocities of the car and passenger are independent.. Hope this helps you!(: Good luck.

Quantitative data is always numerical, like measurements or counts of things. Qualitative data is categorical, like descriptions and names. The type of shape is qualitative, and the mass is quantitative.

What quantity of aluminium is deposited when a current of 10A is passed through a solution of aluminium salt for 1930s? (All=27,F=96500cmol)

Answers

The amount of aluminum deposited when a current of 10A is passed through a solution of aluminum salt for 1930s is 5.4 g.

What is electrochemical cell ?

An electrochemical cell converts chemical energy into electrical energy. Metals with higher negative electrode potential undergo oxidation and its ionization produces electron flow through the solution.

The weight of the metal that deposited by reduction is related to the mass of metal, current passed and time as follows:

w = z It

where z = E/96500 F

Equivalent mass of Al, E = 27 g

t = 1930 s

current I = 10 A.

Now, the weight of aluminum metal deposited is calculated as follows:

w = 1930 s × 10 A × 27/96500 = 5.4 g.

Therefore, the weight of Al deposited on the electrode is 5.4 g.
