Answer: 1.88 N
Explanation:
Data:
Force = 4.00N
angle = 62°
horizontal force = ?
Solution:
The trigonometric ratio that relates horizontal - leg to hypotenuse is the cosine.
That ratio is:
horizontal - leg
cos(angle) = -------------------------
hypotenuse
So, applied to the force, that is:
horizontal force
cos (angle) = -----------------------------------
total force
So, clearing the horizontal component you get:
horizontal force = force * cos (angle)
Substitute the data given:
horizontal force = 4.00N * cos(62°) = 4.00N * 0.4695 = 1.88 N
Answer: 1.88N
Answer: Changes in pressure have very little effect on the volume of a liquid. Liquids are slightly incompressible because any increase in pressure can only slightly minimize the distance between the closely packed molecules. Hope this helps.
Explanation:
This co -relates to continent drift theory.
This theory states that the outer rigid layer of the earth or the lithosphere is divided into a couple of dozen "plates" that move around across he earth's surface relative to each other. That is why Alfred Wegener noticed that Africa and South America seem to fit together.
Though Wegener's hypothesis lacked a geological mechanism to explain how the continents could drift across the earth's surface as he proposed.
Answer:
<h3>The answer is 16.67 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>16.67 m/s²</h3>
Hope this helps you
If I am at the station that the train is approaching, and if the train is making some kind of steady sound, then as the train draws closer, I hear the amplitude of the sound steadily increasing ... it gets louder and louder as the train gets closer and closer to me.
(The frequency of the sound I hear is higher than the frequency of the sound the train is actually making, but I don't know that, because I have no idea what frequency sound the train is actually making.)
=================================
If anybody tries to tell you that the frequency of the sound from the train keeps getting higher and higher, please tell that person to come see me, and I will straighten him out. It doesn't.
