Explanation:
this is a chemistry question ???
anyway, it is clearly A, as seatbelts try to counteract the inertia a moving body (our bodies riding in a car) has, when the environment (the car) of this body is suddenly coming to a stop.
this inertia would otherwise try to move the body still forward resulting in a headfirst crash into and often through the windshield. which causes much more damage to the body than the bruises caused by the pressure of the seatbelts against the body counteracting the body's inertia.
but also clearly, all 3 laws play a role.
the force with which the moving body has to deal when smashing into the windshield and potentially then other objects outside the car is described by the second law.
and for any action (crash) there are corresponding reactions (like the conversion of the crash energy into some absorbing reaction : damaged soft and hard tissue in the human body, crumbled car bodies,...).

Answer:
I think it's C or D Sorry if I'm Wrong
Explanation:
it just makes the most sense to me
Answer:
See explanation.
Explanation:
This isn't chemistry. Its physics. Kinetic energy (water) to electric energy (dam) as the hydroelectric dam works. Then, as the current travels from the plant to your crib, electric energy to heat energy (wire resistance). Then when you are using the dryer electric energy to heat energy (hot air) and sound energy (air particles vibrate due to the heat energy).
Answer:
V = 12.93 L
Explanation:
Given data:
Number of moles = 0.785 mol
Pressure of balloon = 1.5 atm
Temperature = 301 K
Volume of balloon = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will put the values.
V = nRT/P
V = 0.785 mol × 0.0821 atm.L/ mol.K × 301 K / 1.5 atm
V = 19.4 L /1.5
V = 12.93 L
