A 60-kg person is traveling in a car moving at 16 m/s, when the car hits a barrier. The person is not wearing a seat belt, but is stopped by an air bag in a time interval of 0.20 s. Determine the average force that the air bag exerts on the person?

Answers

Using conservation of momentum, we can solve for the force that the air bag exerts on the person.

Recall the equation for momentum (p):

p = mv = F*dt

We can solve for total momentum, then divide by out time interval. This gets us:

(60kg)(16m/s) = F(0.2s)F = 4800N

F = 4800N

15. With an average surface temperature of about 737 K, _______ is the hottest planet.
A. Mars
B. Mercury
C. Earth
D. Venus

Answers

Correct answer choice for question 1 is:


D) Nebula.


Explanation:


A nebula is an interstellar cloud of dust, hydrogen, helium and other ionized vapors. Basically, the nebula was a sign for any distributed enormous object, including galaxies behind the Milky Way. Most nebulae are of a large size, some are numbers of light years in diameter. A nebula that is almost visible to the human eye from Earth would appear larger, but no flashing, from close by. The Orion Nebula, the glowing nebula in the sky that controls a region twice the diameter of the full Moon, can be observed with the naked eye but was dropped by early scientists.

Correct answer choice for question 2 is :


D) Venus


Explanation:


Venus is the second planet from the Sun, revolving it every 224.7 Earth days. It has the largest revolution time of any planet in the Solar System and turns in the different direction to most other planets. It does not have any real satellites. It is the second glowing natural object in the night sky after the Moon, leading an obvious magnitude of 4.6 bright quite to throw shadows at night and, unusually, obvious to the naked eye in full daylight.
     The cloud of interstellar dust and gas that forms a star is known as a nebula. With an average surface temperature of about 737K, venus is the hottest planet. Hope this helps, and sorry your question didn't get answered in time.

A 0.100-kilogram apple falls from a height of 1.50 meters to 1.00 meters. Ignoring frictional effects, what is the kinetic energy of the apple at this height?

Answers

Answer:

The kinetic energy of the apple at this height is 0.49 J.

Explanation:

Mass of apple, m = 0.1 kg

It falls form a height of 1.5 meters to 1 meters. We need to find the kinetic energy of the apple at this height. As the apple is falling, the decrease in potential energy is equal to the increase in kinetic energy. Using the conservation of energy as :

E_k=-\Delta E_p

E_k=-mg\Delta h

E_k=-0.1* 9.8* (1-1.5)

E_k=0.49\ J

So, the kinetic energy of the apple at this height is 0.49 J. Hence, this is the required solution.
before the fall, at 1.50 m, all the energy is potential and none is kinetic.

As it's falling the apple has both kinetic and potential energies. The decrease in potential energy is equal to the increase in kinetic energy

KE = -ΔPE
= -mgΔh
= -(0.100 kg)(9.81 m/s²)(1.00 m - 1.50 m)
= 0.491 J

Brody and Ethel are arguing about waves. Brody says that waving his hand back and forth is a scientific wave. Ethel says that it is not. Which statement best describes who is correct?-Brody is correct because the wave involves an input of energy.
-Ethel is correct because energy is not carried from one place to another.
-Brody is correct because the pattern repeats.
