The answer of this is "Its surface composition"
Mars is the fourth planet from the Sun and the next planet beyond Earth. It is, on average, more than 142 million miles from the Sun.
Its surface is rocky, with canyons, volcanoes, dry lake beds and craters all over it. Red dust covers most of its surface. Mars has clouds and wind just like Earth. Sometimes the wind blows the red dust into a dust storm. Tiny dust storms can look like tornados, and large ones can be seen from Earth. Mars’ large storms sometimes cover the entire planet.
Mars has about one-third the gravity of Earth. A rock dropped on Mars would fall more slowly than a rock falls on Earth. A person who weighs 100 pounds on Earth would only weigh about 38 pounds on Mars because of the reduced gravity.

an electron traveling due north enters a region that contains a uniform magnetic field that points due east. in which direction will the electron be deflected?
An electron moving north will slow down and eventually reverse its direction if it enters an electric field that points north.
What is a uniform magnetic field?Parallel straight lines that are evenly spaced apart represent a homogenous magnetic field. The direction that a tiny magnet's north-seeking pole points indicates the flux direction. The flux lines form closed loops and are continuous.While the magnetic field around a bar magnet is not uniform, the lines of the Earth's magnetic field are uniform (parallel and equally spaced) (neither parallel nor equidistant).If the magnetic field's lines are parallel, the magnetic field's strength will be the same at every point, meaning the field's strength will remain constant.

al walks down to the bottom of an escalator that is moving up and he counts 150 steps. his friend, bob, walks up to the top of the escalator and counts 75 steps. if al's speed of walking (in steps per unit time) is three times bob's walking speed, how many steps are visible on the escalator at a given time? (assume that this value is constant.)
The minimum number of steps visible on the escalator at any given time is 150.
Let's assume that the escalator is moving upward at a constant rate, so that the distance traveled by al in one unit of time is equal to three times the distance traveled by bob in one unit of time, which means that al will take three times as many steps as bob does.
Let's say that al walks down 50 steps per unit time, and bob walks up 25 steps per unit time. We know from our earlier assumption about constant speed that al will take three times as many steps as bob does, so if al walks down 50 steps per unit time, then bob walks up 75 steps per unit time—but we also know that there are 150 total visible steps on the escalator at any given point in time.

when the displacement of a mass on a spring is 1/2 a , what percentage of the energy is kinetic energy?
The formula for total mechanical energy at maximum displacement (amplitude) is
ME = KE + PE = 0 plus (1/2)
*k*A^2 = (1/2)*k*A^2
Now, mechanical energy is constant during the displacement of a mass on a spring.
Now, when x equals A/2, or when displacement is equal to half of amplitude, then
PE = (1/4)*(1/2)*k*x2 = (1/4)*(1/2)*k*(A/2)*2
PE = (1/4)*ME
PE = ME - (1/4)*ME - KE = ME
KE = (3/4)*ME
KE/ME = 3/4 = 0.75
Part B.
When KE = PE, displacement is required.
If this event happens at 'x' displacement, then at this point we are aware that
ME = KE plus PE equals (1/2)*k*A2.
Because KE = PE
ME = PE + PE = (2*PE)*k*A2
PE = (1/4)*k*A^2
PE = (1/2)*k*x2 at x displacement, thus
(1/2)*k*x^2 = (1/4)*k*A^2
x^2 = (1/2)*A^2
(x/A)^2 = 1/2

In the given question we have,
mass of testing Car = 1550 kg
initial velocity of car on test track = 10.0 m/sec
final velocity of car on test track = 30.0 m/sec
Net force that track has applied to car (F) = m × a
where m ----> mass of car
a ----> acceleration
firstly, we shall find out the value of acceleration.
Using the relation formula between initial velocity, final velocity and acceleration
v - u = at
where, v---> final velocity
u---> initial velocity
a---> acceleration
t-----> time
given , v = 30m/sec , u= 10m/sec , t = 10 sec
10× a = 30 - 10 = 20 => a = 2m/sec²
So, Net force = mass × acceleration
F = 1550×2 = 3100 Newton
Hence, the net force applied on car during 10.0 sec interval is 3100 Newton.

collecting the low frequency (high amplitude signal) data points in k-space at the start of the scan (in a rectilinear fashion) is known as
Collecting the low frequency data points in k-space at the start of the scan is known as centric.
What is k-space?k-space represents the spatial frequency information of an object in two or three dimensions. k-space is defined by the space covered by the phase- and frequency-encoded data. The relationship between k-space data and image data is the Fourier transform.
A wave is characterized by its wavelength (λ), the distance between two corresponding points or consecutive peaks. Wavenumber (k) is simply the reciprocal of wavelength and is given by the equation k = 1 / λ Therefore, the wavenumber (k) is the number of waves or cycles per unit path.
The amplitude of the frequency encoding gradient determines how much k-space is filled left to right or left to right. This determines the size of pixels in the frequency direction.

why does the atmosphere of saturn appear to have only half the helium content of jupiter? why does the atmosphere of saturn appear to have only half the helium content of jupiter? much of saturn's helium has reacted with water and formed helium oxide. much of saturn's helium has differentiated towards its center. because saturn is so much colder, helium does not show up as strongly in its spectrum. a red dwarf, jupiter has fused some of its hydrogen into helium, whereas saturn, a colder planet, has not. saturn was formed farther from the helium rich sun.
The correct answer is option C.
The atmosphere of Saturn appear to have only half the helium content of Jupiter because Saturn is so much colder, helium does not show up as strongly in its spectrum.
The planet Saturn is a giant ball of gases including hydrogen, helium and methane. All these gases make up a thick atmosphere of the planet.
In general, the concentration of hydrogen is about 96.3%, helium 3.25% and methane 0.45%.
Clouds on Saturn are composed of ice crystals of ammonia and the temperature is around -400F which is much colder then Jupiter.
Thus, atmosphere of Saturn appear to have only half the helium content of Jupiter because Saturn is so much colder.

a boy pushes a wheelbarrow with a force of 36 n to the left. a frictional force of 13 n opposes the motion. the wheelbarrow and its contents have a mass of 37 kg. calculate the acceleration of the wheelbarrow:
The acceleration of the wheelbarrow is 0.621 m/s^2 .
There will be equal force applied on both side, in that case the object will be having zero motion and zero acceleration.
But in the case when there is more force applied in one direction than other side force then there will be acceleration on the object.
This acceleration is equal to the ΔF/m.
where ΔF is the difference of the forces applied on the both direction
and m is the total mass of the object.
According to the question, we have m = 37Kg
ΔF = (36-13) n = 23 n
so a = 23/37 = 0.621 m/s^2
so acceleration of the wheelbarrow is 0.621 m/s^2 .

What is meant by newtons law?According to Newton's first law, unless pushed to alter its condition by the operation of an external force, every object will continue to be at rest or in uniform motion in a straight line. Inertia is the propensity to resist changes in a condition of motion.
The motion of an item is related to the forces operating on it by Newton's equations of motion. According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration.
Newton's first law states that unless a net external force acts on an object, it will either remain at rest or continue moving at a constant speed.
