Answer:
The answer is a=b=c=3.833 cm
Explanation:
Lets call the variables a=side a b=side b c=side c
We have that the formula of the equilateral triangle for its height is:
1)h=(1/2)*root(3)*a
2) If we resolve the equation we have
2.1)2h=root(3)*a
2.2)(2h/root(3))=a
3) After the replacement of each value we have that
a=2*3.32/1.73205
a=3.833 cm
And we know that the equilateral triangle has the same value for each side so a=b=c=3.833 cm
An object that weighs 100 tons and is floating is displacing exactly 100 tons of the fluid, and the buoyant force on it is 100 tons. The vertical forces on it are balanced (add up to zero), and that's why it isn't accelerating up or down.
The charge of an anti-charm quark is approximately equal to +5.33 ×10⁻²⁰ C.
<h3>What are electrons?</h3>
The electrons are the spinning objects around the nucleus of the atom of the element in an orbit.
The charge on electron is equal to e = -1.6 x 10⁻¹⁹C
The charge of an anti- charm quark is +23 times the magnitude of charge on electron.
So, charge on anti- charm quark is
q = +1/3 x ( 1.6 x 10⁻¹⁹C)
q = +5.33 ×10⁻²⁰ C
Thus, the charge of an anti-charm quark is approximately equal to +5.33 ×10⁻²⁰ C.

Answer:
A) Speed
Explanation:
The medium of transmission(air) does not change before and after reflection. The sound still travels in air after the reflection. i.e the medium of transmission of sound is constant.
Since the medium of transmission remains constant, speed also remains constant. Speed only changes when the medium of transmission changes.
