The most recent NASA mission on Mars is Mars Science Laboratory. Its key component was Curiosity rover.
Rover has celebrated his first landing anniversary yesterday (Martian year, that is 687 Earth days).
Curiosity managed to find traces of water on Mars, so it's possible that there used to be some life on Mars.
Since landing Curiosity moved only about 5 miles form the landing site (it suffered wheel damage).

What are the three longest wavelengths for standing sound waves in a 121-cm-long tube that is (a) open at both ends and (b) open
irina [24]

Answer:A)For open pipe

1stπ=484cm

2nd wavelength=161.3cm

3rd is=96.8cm

B)For closed pipe

1st wavelength=242cm

2nd=121cm

3rd wavelength=80.7cm

Explanation:

An open pipe produces a standing waves whose wavelength is related to it's length(length of pipe) by nL/4=π ,where n represent odd integers 1,2,3...

So the first note called fundamental note or 1st Harmonic is L=π/ 4,121=π/ 4

π= 121×4=484cm

Third harmonic,L=3π /4

So π= 4l/3=4×121/3=161.3cm

The 3rd wavelength is

Fifth harmonic=

π =4l/5=4×121/5=96.8cm

For a pipe open at one end and closed at the other also called closed pipe

Fundamental note is

2L/n= π where n=1,2,3....ie integers

First wavelength

π=2L=2×121=242cm

Second wavelength

π=L=121cm

Third is

π=2L/3=2×121/3=80.7cm

Astronomers classify stars according to their (1 point) distance from Earth. color, size, and absolute brightness. age and paral
charle [14.2K]

Answer:

All of the above

Explanation:

Astronomers use all of those measures to classify stars. If you want to look more into classifying stars, check out the Hertzsprung-Russel Diagram. It covers how to identify red giants, main sequence, dwarf stars, ect. Distance from earth is typically measured in light years. The color of stars generally determines how hot they are. (Blue stars are the hottest) Also, the parallax method is used to measure stars that are closer to earth. This method relies heavily on geometry though.

Hope this helped!

A tennis player tosses a tennis ball straight up and then catches it after 2.00 s at the same height as the point of release. (a
Readme [11.4K]

Answer:

Part a)

a = -9.81 m/s/s

Part b)

v = 0

Part c)

v = 9.81 m/s

Part d)

H = 4.905 m

Explanation:

Part a)

During the motion of ball it will have only gravitational force on the ball

so here the acceleration of the ball is only due to gravity

so it is given as

a = g = 9.81 m/s^2

Part b)

As we know that ball is moving against the gravity

so here the velocity of ball will keep on decreasing as the ball moves upwards

so at the highest point of the motion of the ball the speed of ball reduce to zero

v_f = 0

Part c)

We know that the total time taken by the ball to come back to the initial position is T = 2 s

so in this time displacement of the ball will be zero

\Delta y = 0 = v_y t + \frac{1}{2} at^2

0 = v_y (2) - \frac{1}{2}(9.81)(2^2)

v_y = 9.81 m/s

Part d)

at the maximum height position we know that the final speed will be zero

so we will have

v_f^2 - v_i^2 = 2 a d

here we have

0 - (9.81^2) = 2(-9.81)H

H = 4.905 m
