Answer:
The moment of a given force about a given axis of rotation can be decreased by decreasing the perpendicular distance of force from the axis of rotation.
Answer:
the diameter of the smaller vessels is 9.90 mm
Explanation:
The computation of the diameter of the smaller vessels is given below;
Given that
The larger vessel of the diameter is 14mm
So,
d1 = 7 mm
let us assume the diameter of the smaller artery is d2
Now we used the equation of continuity i.e.
v × pi × d1^2 = 2 × v × pi × d2^2
14^2 = 2 × d2^2
d2 = 9.90 mm
Hence, the diameter of the smaller vessels is 9.90 mm
<span>So the question is how can a spoon sound like a bell. Sound waves are mechanical waves that have their frequency. When a source, in this case a spoon and a bell oscilate, they produce sound waves. If they produce those sound waves in the same frequency, then we can say they produce the same tone thus they sound the same.</span>
Answer:
<em>a. t = 2.02 s
</em>
<em>b. d = 20.2 m</em>
Explanation:
<u>Horizontal Motion
</u>
If an object is thrown horizontally from a height h with a speed v, it describes a curved path ruled exclusively by gravity until it eventually hits the ground.
The time the object takes to hit the ground can be calculated as follows:
The time does not depend on the initial speed.
The range or maximum horizontal distance traveled by the object can be calculated by the equation:
The man standing on the edge of the h=20 m cliff throws a rock with an initial horizontal speed of v=10 m/s.
a.
The time taken by the rock to reach the ground is:
t = 2.02 s
b.
The range is:
d = 20.2 m
