An 80kg astronaut traveled to the moon, where gravity is one-sixth (116) as

Physics

PIT_PIT [208]3 years ago
7 0

Answer:

Wmoon = 131 [N]

Explanation:

We know that the weight of a body is equal to the product of mass by gravitational acceleration.

Since we are told that the gravitational acceleration of the moon is equal to one-sixth of the acceleration of Earth's gravitation. Then we must multiply the value of Earth's gravitation by one-sixth.

w_{moon}=\frac{1}{6} *m*g\\w_{moon}=\frac{1}{6} *80*9.81\\w_{moon}=130.8 [N] = 131 [N]

If you can walk 3 miles per hour, how much is that in meters per second?
deff fn [24]

To convert 3 miles per hour into m/s, first we have to convert miles in to meter and then hour in to second.

As 1 miles = 1.609344 km = 1.609344\times 10^3 m = 1609.3 m and1 hour=60 minutes = 60\times 60= 3600s

Therefore,

3 miles/ h=\frac{3\times1609.3m}{3600s} =1.34 m/s

PLEASE PLEASE HELP!

Well, the relationship between the net force and mass and acceleration of an object are directly related, as per the equation - Fnet = ma.

Thus the solution is A. As the net force of an object decreases, the object's acceleration also decreases, mass is kept constant.

A car’s tire rotates 5.25 times in 3 seconds. What is the tangential velocity of the tire?
Lena [83]

The tangential velocity of the car's tire is the product of the angular velocity and radius of the car's tire which is 11(r) m/s.

<h3>Angular velocity of the tire</h3>

The angular velocity of the tire is the rate of change of angular displacement of the tire with time.

The magnitude of the angular velocity of the tire is calculated as follows;

ω = 2πN

where;

  • N is the number of revolutions per second

ω = 2π x (5.25 / 3)

ω =  11 rad/s

<h3>Tangential velocity of the tire</h3>

The tangential velocity of the car's tire is the product of the angular velocity and radius of the car's tire.

The magnitude of the tangential velocity is caculated as follows;

v = ωr

where;

  • r is the radius of the car's tire

v = 11r m/s

4. Which of the following is the DNA sequence that a restriction enzyme binds to?
Elina [12.6K]

Answer:

DNA ligase

Explanation:

DNA Ligase is the enzyme that binds fragments of DNA together by forming two phosphodiester bonds between the 3' hydroxyl end of one nucleotide with the 5' phosphate end of the other. This reaction requires the hydrolysis of ATP.
