<span>Her center of mass will rise 3.7 meters.
First, let's calculate how long it takes to reach the peak. Just divide by the local gravitational acceleration, so
8.5 m / 9.8 m/s^2 = 0.867346939 s
And the distance a object under constant acceleration travels is
d = 0.5 A T^2
Substituting known values, gives
d = 0.5 9.8 m/s^2 (0.867346939 s)^2
d = 4.9 m/s^2 * 0.752290712 s^2
d = 3.68622449 m
Rounded to 2 significant figures gives 3.7 meters.
Note, that 3.7 meters is how much higher her center of mass will rise after leaving the trampoline. It does not specify how far above the trampoline the lowest part of her body will reach. For instance, she could be in an upright position upon leaving the trampoline with her feet about 1 meter below her center of mass. And during the accent, she could tuck, roll, or otherwise change her orientation so she's horizontal at her peak altitude and the lowest part of her body being a decimeter or so below her center of mass. So it would look like she jumped almost a meter higher than 3.7 meters.</span>
Answer:
Explanation:
From frequency of oscillation
Initially with the suspended string, the above equation is correct for the relation, hence
where k is force constant and m is the mass
When the spring is cut into half, by physics, the force constant will be doubled as they are inversely proportional
Employing f2/ f1, we have
Answer:
Iron
Explanation:
The buoyant force equals to the weight of water being displaced by the object.
Since, the volume of both iron and wood is equal and the wood is not completely submerged, but the iron block is completely submerged i.e more volume of the water is being displaced by the iron block.
Hence, the buoyant force is more on the iron.
Valence electrons is the correct answer
If you read the question carefully, you can find the answer right there in it.
In fact, you don't even have to read the whole question ... you only need to read one word.
In fact, you don't even have to read the whole word ... you only need to read part of the word.
The word to read is "wavelength".
The important part of the word is "length".
<em>Now</em> it's time to look at the picture:
#1 is a height.
#2 is a place on the wave
#4 is a place on the wave
<em>#3 </em>is the only thing in the picture that's a "length" of anything.
