Answer:
Part a)
Part b)
So density of atmosphere at Martian Surface is very less than the density at Earth.
Explanation:
Part a)
As per ideal gas equation we know that
here we know that Martian atmosphere is equivalent to that of carbon
so we will have
now we will have
Part b)
Now for the earth surface the density of air is given for
so we will have
So density of atmosphere at Martian Surface is very less than the density at Earth.
For a certain interval of time, an object is acted on by a constant non-zero force. For this interval of time . . . . .
A. The object is at rest. No. From F=ma, if F is not zero, the object can't remain at rest.
<em>B.</em> <em>The object's velocity changes.</em> <em>Yes.</em> From F=ma, if F is not zero, there must be acceleration.
C. The object's velocity can only increase. No. It might decrease.
D. The object is moving with constant velocity. No. From F=ma, if F is not zero, there must be acceleration.
<em>E.</em> <em>The object is accelerating.</em> <em>Yes.</em> From F=ma, if F is not zero, there must be acceleration.

It is important to wear protective equipments during games and practices.
Explanation:
Practice is a review of what is about to happen in some time to come and with practice ,the future can be trusted.
During practice it is very important to use protective gears or equipments because without them, injuries and accidents are liable to occur.
During the major game it is also important to prevent accidents or big injuries as the equipments protect each vital part of the body.
To answer the problem we would be using this formula which isE = hc/L where E is the energy, h is Planck's constant, c is the speed of light and L is the wavelength
L = hc/E = 4.136×10−15 eV·s (2.998x10^8 m/s)/10^4 eV
= 1.240x10^-10 m
= 1.240x10^-1 nm
