An astronaut has a mass of 100 kg and has a weight and if 370 N on Mars. What is the gravitational strength on Mars?

Physics
1 answer:
Reika [66]3 years ago
4 0

Answer:

3.7 N/kg

Explanation:

The gravitational strength refers to the amount of gravity acting per unit mass. Hence in this case,

Gravitational Strength = Weight / Mass

= 370 / 100

= <u>3</u><u>.</u><u>7</u><u>N</u><u>/</u><u>k</u><u>g</u>

Impact of Synthetic Materials Discussion
Wittaler [7]

With the below stated fact  I think that  the pros of using synthetic materials outweighs the cons.

Before we answer the question

If the pros of using synthetic materials outweigh the cons or otherwise, let us first establish the what a synthetic material is and its pros and cons

Synthetic material

Synthetic material is a material in which a substances are changed chemically to produce a material with different characteristics.

Types of Synthetic material

  •    Plastic bag  
  •    Synthetic fiber/cloth  
  •    Artificial sweetener
  •    Synthetic fuel      
  •    Aspirin

Pros of Synthetic materials

  • They are used in construction because of there strong bonding
  • They can be molded
  • They can be colored into any shade
  • They are cheap

Cons of Synthetic materials

  • Sometimes none degradable
  • They do not absorb water.
  • They are highly flammable
  • Melts easily

In conclusion

Although Synthetic materials has so very pressing disadvantages to human kind it is unrefusable the importance of Synthetic materials to the day to day live of all humans

Therefore, I think that  the pros of using synthetic materials outweighs the cons

A running mountain lion can make a leap 10.0 mlong, reaching a maximum height of 3.0 m. What is the speed of the mountain lion j
nika2105 [10]

To solve this problem we will use the kinematic equations of descriptive motion of a projectile for which both the height reached and the distance traveled are defined. From this type of movement the lion reaches a height (H) of 3m and travels a horizontal distance (R) of 10 m. Mathematically the equations that describe this movement are given as,

H = \frac{v_0^2sin^2\theta}{2g}

R = \frac{v_0^2 sin 2\theta}{g}

Dividing the two equation we have that

\frac{H}{R}=\frac{\frac{v_0^2sin^2\theta}{2g}}{\frac{v_0^2 sin 2\theta}{g}}

\frac{H}{R}= \frac{sin^2\theta}{2}*\frac{1}{sin2\theta}

\frac{H}{R}= \frac{sin^2\theta}{2}*\frac{1}{2sin\theta cos\theta}

\frac{H}{R}= \frac{1}{4} \frac{sin\theta}{cos\theta}

\frac{H}{R}= \frac{1}{4} tan\theta

Substituting values of H and R, we get

\frac{3}{10} = \frac{1}{4} tan\theta

\theta = tan^{-1} \frac{12}{10}

\theta = 50.2\°

Substituting the value of \theta in equation we get,

H = \frac{v_0^2sin^2\theta}{2g}

v_0^2 = \frac{H 2g}{sin^2\theta}

v_0^2 = \frac{3*2*9.8}{sin^2(50.2)}

v_0^2 = 99.62

v_0 = \sqrt{99.62}

v_0 = 9.98m/s

Therefore the speed of the mountain lion just as it leaves the ground is 9.98m/s at an angle of 50.2°

Passengers in a high-flying jumbo jet feel their normal weight in flight, while passengers in an orbiting space vehicle do not,
daser333 [38]

Answer:E none of the above

Explanation:

When a space shuttle orbiting around the earth then earth gravitational force keeps the shuttle in its orbit by providing centripetal force. Tangential velocity makes the shuttle to revolve around the earth. Earth gravitational pull is significant to make the shuttle move in orbit while the Passengers feel weightlessness because they are falling downward but never able to reach as they move fast enough such that earth curves away them.
