Answer: Meteors
Explanation:
The moon does not have an atmosphere. Thus, it does not have weather patterns like on Earth. No winds blow on it unlike on Earth where wind and water cause soil erosion.
On moon, high speed space dust and rocks of all sizes hit and cause the erosion of rocks. In the absence of atmosphere, these space rocks are not burnt away but hit the surface creating craters.
Free fall without air resistance:
g=9.81 m/s²
t=235 s
h=?
h=0.5*g*t²
h=0.5*9.81*235²
h=270879m =270 km
Answer:
they were slaves, so they did practically everything anyone didn't do.
Explanation:
btw, which war? or battle?
Answer:
1.31×10⁻⁴ C or 131 μC
Explanation:
From the question,
Applying Coulomb's Law,
F = kqq'/r²..................... Equation 1
Where F = Force between the charges, q = first charge, q' = second charge, r = distance between the charges, k = coulomb's constant.
make q' the subject of the equation
q' = F×r²/(kq)
q' = Fr²/kq................ Equation 2
Given: F = 1240 N, r = 16.4 cm = 0.164 m, q = 28.4 μC = 2.84×10⁻⁵ C,
Constant: k = 8.98×10⁹ Nm/C²
Substitute these values into equation 2
q' = (1240×0.164²)/[(2.84×10⁻⁵)×(8.98×10⁹)
q' = (33.35104)/(25.5032×10⁴)
q' = 1.31×10⁻⁴ C
q' = 131 μC
All of the options provided are true about performing a swing. A swing
dance is also known as a square dance.
This type of dance involves the following steps such as
- The gentleman puts his right hand on the lady's back.
- The lady puts her left hand on the gentleman's shoulder.
