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
The pitch of a sound you hear depends on the frequency of the sound wave. A high frequency sound wave has a high pitch, and a low frequency sound wave has a low pitch.
Answer
given,
mass of object 1 = 4 Kg
Speed of object 1 = 2 m/s
mass of object 2 = 1 Kg
speed of object 2 = 4 m/s
KE of the object 1 = 
= 
= 8 J
KE of the object 2 =
= 
= 8 J
Kinetic energy of both the object is same hence,Work done by both the object will also be same.
It is given that braking force is same in both cases.
So, distance travel by Both the object will be same.
Depends on if the samples are different kinds of sand
