Answer:
The correct solution is "15 kgm/s". A further explanation is given below.
Explanation:
The given values are:
Mass,
m = 5 kg
Velocity,
v = 3 m/s
By applying the formula of momentum, we get
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
Answer:
A. the magnitude of the force between the spheres is 3.97 x 10⁻⁴ N
B. the magnitude of its initial acceleration is 5.83 m/s²
Explanation:
given information:
metal sphere's mass, m = 0.1 g = 1 x 10⁻⁴ kg
charge, q = -21 nC = -2.1 x 10⁻⁸
r = 10 cm = 0.1 m
What is the magnitude of the force between the spheres?
F₁₂ = k q₁q₂/r²
= ( 9 x 10⁹) (-2.1 x 10⁻⁸)²/(0.1)²
= 3.97 x 10⁻⁴ N
If the upper sphere is released, it will begin to fall. What is the magnitude of its initial acceleration?
mg - F₁₂ = ma
a = g - (F₁₂/m)
= 9.8 - (3.97 x 10⁻⁴/1 x 10⁻⁴)
= 5.83 m/s²
Answer:
Visible light
Explanation:
Electromagnetic spectrum is the classification of the electromagnetic waves based on their frequency and wavelength. In order from the shortest to the longest wavelength, we have
Gamma rays
X-rays
Ultraviolet
Visible light
Infrared radiation
Microwaves
Radio waves
All these waves are invisible to human eye, except for the visible light part. Visible light is perceived as a different color by the human eye, depending on the wavelength of the light. In particular, we have:
Violet: 380 - 450 nm
Blue: 450 - 495 nm
Green: 495 - 570 nm
Yellow: 570 nm - 590 nm
Orange: 590 nm - 620 nm
Red: 620 nm - 750 nm
The ardor determines the result of a reaction.
[formula A]+[formula B]—> [formula C]
Here, the arrow signifies that when adding formula A and B, you get formula C. An arrow can also go both directions.
[formulaA]+[form.B]<—>[formulaC]+[form.D]
Here, the double sided arrows means that adding formulas A and B will give you C and D, and adding formulas C and D will give you A and B.
The radio because u arent pushing as many watts out and it wont pass through as much
