Answer:
The frictional force producing this deceleration would have a magnitude of 
.
Explanation:
The velocity of this object changed by 
in 
. The acceleration of this object would be:
.
Let 
denote the mass of this object. By Newton's Second Law of Motion, the net force on this object would be:
.
(
.)
If the floor is level, friction would be the only unbalanced force on this object. Thus, the magnitude of the frictional force on this object would also be 
, same as the magnitude of the net force on this object.
I think the first one is 40*40
Answer:
3.77 Hz
Explanation:
The beat frequency that is heard can be calculated using the following equation:
<u>Where:</u>
f₁ = 110 Hz
<u>With:</u>
<em>T₁ = 594 N </em>
<em>T₂ = 554 N </em>
Hence, the beat frequency is:
Therefore, the beat frequency that is heard when the hammer strikes the two strings simultaneously is 3.77 Hz.

Explanation:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. ... Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
