Answer:
Mars has a thin atmosphere
Explanation:
Okay, so this is going to sound crazy but bare with me. Mar's atmosphere is thin. There is little to no gravitational pull for the atmosphere to stay. Also, no, humans will not be able to live on Mars because the atmosphere, quite literally, contains 1% oxygen. Hopefully this helps! Earth's is thick because of the gravitational pull and gases in Earth's surface.

Explain what would happen if an ebonite rod charged with fur is brought together with an acetate rod charged with silk
Answer:
The ebonite becomes negatively charged, and the fur becomes positively charged.
Explanation:
When an ebonite rod is rubbed against animal fur, some of the electrons from atoms of the fur are transferred to the rod.The ebonite becomes negatively charged, and the fur becomes positively charged.(a) A positive charge (+) and a negative charge (–) attract each other. (b) Two negative charges repel each other. (c) Two positive charges repel each other.

5) which statement describes Kepler's third law of orbital motion? Answer The square of orbital period is proportional to the cube of the semi-major axis.
Explanation:
I just took the connexus quick check and got a 100%
T2 ∝ a3 is the relation that describes Kepler’s third law of orbital motion, therefore the correct answer is option C.
What are Kepler's laws of planetary motion?There are three laws of Kepler as follows,
The orbit of the planet is elliptical and the sun is present at one of the two foci of the elliptical route followed by the rotating planet.
A line segment linking a planet and the Sun covers equal regions throughout equal intervals of the time period.
The semi-major axis length of an elliptical planet's orbit is equal to the square of the planet's orbital period.
T2 ∝ a3 is the relation that describes Kepler’s third law of orbital motion,
Thus, the correct answer is option C.

x0 = 0 m
Y-Yo= 80m
V0 = 800m/s -30o inclined from horizontal
Xf= ?
t = ?
Step 3 * A 2 dimensional problem so break it down into x component and y component
Step 4 x component
x= [Vox ][cos 30o][t]
x= [800m/s][cos 30o][tsec]
x=[692.8m/s][tsec] <---------------Need t
Step 5 y component
Y-Yo= Voy - 1/2gt2
80m= -[v][sin30o][t] -1/2gt2
1/2gt2+[v][sin30o][t]+80m=0 <-------Form Quadratic Equation
Solve for t
t= -[v sin 30] +/- [(v sin 30)-(4)(1/2)(9.8)(80)]1/2
(2)(1/2)(9.8)
t= 400+/- 398

Answer: 1 sig fig
Explanation: because 0s aren‘t significant and yes decimal points matter but after the decimal it’s a 0. So it is 1. If it was 0.30 it would be 2 sig figs but 0.03 would be one sig fig.
Jake lifted a 10-kg bell by a distance of 0.50 meters in 0.50 seconds. How much power did Jake use?
Answer:
10 watts
Explanation:
first calculate work.
Work =force×distance cos thita
10Kg×0.50M cos 0= 5joules
Therefore, Power=Work÷ Time
Therefore, 5joules÷0.50s=10 watts.

Explanation:
A jet airplane is in level flight. The mass of the airplane is m = 8930 kg. The airplane travels at a constant speed around a
circular path of radius R = 8.01 mi and makes one revolution every T = 0.106 h. Given that the lift force acts perpendicularly
upward from the plane defined by the wings, what is the magnitude of the lift force acting on the airplane?
At what angle is the airplane banked?
Answer:
Explanation:
The lift force will have a vertical component equal to the weight of the plane and a horizontal component sufficient to supply the needed centripetal accleration.
R = 8.01 mi = 12891 m
ω = 2π/T = 2π/(0.106(3600)) = 0.016465 rad/s
F = m√(g² + (ω²R)²)
F = 8930√(9.81² + (0.016465²(12891))²)
F = 8930√(9.81² + 3.49²)
F = 92,996.480...
F = 93.0 kN
θ = arctan(3.49/9.81) = 19.6°

Explanation:
1 oto chạy trên 1 đoạn đường thẳng từ địa điểm A đến địa điểm B phải mất 1 khoảng thời gian t, Tốc độ của oto trong nửa đầu của khoảng thời gian này là 60km/h và trong nửa cuối là 40km/h. Tính tốc độ trung bình của oto trên cả đoạn đường AB
Answer:
Explanation:
t = (½d)/60 + (½d)/40
t = (½d)/60(2/2) + (½d)/40(3/3)
t = (½d)2/120 + (½d)3/120
t = (½d)5/120
t = (½d)/24
t = d/48
v = d/t
v = d / (d/48)
v = 48 km/h

Book A with a mass of 1.00 kg is placed on a horizontal table. Book B with a mass of 0.500 kg is placed on top of book A. What is the magnitude of the normal force exerted on book A by the table?
Answer:
Explanation:
N = mg = (1.00 + 0.500)(9.81) = 14.7 N
The magnitude of the normal force exerted on book A by the table is 14.7 N
ForcesFrom the question, we are to determine the magnitude of the normal force.
The normal force ca be calculated by using the formula
[tex]F_{n} = mg[/tex]
Where [tex]F_{n}[/tex] is the normal force
m is the mass
and g is the gravitational field strength ( g = 9.8 m/s²)
The mass will be addition of the masses since Book B is placed on top of the book.
Thus,
m = 1.00 kg + 0.500 kg = 1.50 kg
Then,
[tex]F_{n} = 1.5 \times 9.8[/tex]
[tex]F_{n} = 14.7 \ N[/tex]
Hence, the magnitude of the normal force exerted on book A by the table is 14.7 N

What is the major difference between metallic bonding and ionic bonding?
Answer:
The key difference between ionic bonding and metallic bonding is that the ionic bonding takes place between positive and negative ions whereas the metallic bonding takes place between positive ions and electrons.
Explanation:
About (metallic bonding) → Metallic bonding is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons and positively charged metal ions.
About (ionic bonding) → Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds

How does the current in a resistor change if the voltage across the resistor is
increased by a factor of 2?
If the voltage across a resistor is increased by a factor of two, the current in the resistor doubles.
What is ohm’s law?When all physical parameters and temperature are constant, Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.
This current-voltage connection may be expressed mathematically as,
The Equation of Ohm's Law;
V∝I
V'∝I'
Hence, if the voltage across a resistor is increased by a factor of two, the current in the resistor doubles.
