Air bags are kept in the steering wheel or
dashboard and expand during a serious collision, usually a front collision that
occurs at over 10 mph. To do its important job, an air bag comes out of the
dashboard at up to 200 mph, faster than the blink of an eye. It is estimated
around 10 inches of space to inflate. The force of an air bag can hurt those
who are too close to it. Driver and front seat passengers should be
moved as far back as practical, mainly people of short built. It is highly suggested
that you be seated no less than 10 inches away from the air bag. Therefore, the answer is letter b.
The sun is actually plasma but let us say that it is actually a Gas ball, as are all stars. All stars are essentially made out of gasses.
E, 63% of the value. I forget the rationale behind it but I learnt that in engineering. 90% confident for that answer.
Answer:

Explanation:Newton.s law of cooling states that the rate of cooling of an object is proportional to the difference between its own temperatures and temperature of its surroundings. Mathematically,
![\frac{dQ}{dt} =-hA [T(t)-T(s)]\\](https://tex.z-dn.net/?f=%5Cfrac%7BdQ%7D%7Bdt%7D%20%3D-hA%20%5BT%28t%29-T%28s%29%5D%5C%5C)

where
is the heat transfer
is heat transfer coefficient
is the heat transfer surface area
is the temperature of the object's surface
is the temperature of the surroundings
Answer:
1. 10.0 J
2. 0.742 m/s
3. 0.494 m/s
4. 0.0249 m
Explanation:
(1/4) The elastic energy in a spring is:
EE = ½ k x²
EE = ½ (502 N/m) (0.2 m)²
EE ≈ 10.0 J
(2/4) The energy in the spring is converted to kinetic energy in the block and work by friction.
EE = KE + W
EE = ½ m v² + Fd
10.0 J = ½ (8 kg) v² + (8 kg × 9.8 m/s² × 0.5) (0.2 m)
v ≈ 0.742 m/s
(3/4) Momentum is conserved.
Momentum before = momentum after
(8 kg) (0.742 m/s) = (8 kg + 4 kg) v
v ≈ 0.494 m/s
(4/4) The kinetic energy of the blocks is converted to work by friction.
KE = W
½ m v² = Fd
½ (8 kg + 4 kg) (0.494 m/s)² = ((8 kg + 4 kg) × 9.8 m/s² × 0.5) d
d ≈ 0.0249 m
