More compressed. moving up = apparent weight (i.e., your norma force) is greater. this means you’ll weighr more and push those springs down even more than you would at rest.
Breaking down energy into food
Answer:
Explanation:
There are 2 ways to help with this. Explain the details, which are fairly simple in this topic, or give the formula. My hope is that an explanation will last longer than memorizing the formula. I give you both.
If a wave has frequency, f, of 3 Hz, its period, T, is
1
3
s
. The wavelength,
λ
, is 5 meters. That means that in the time of one period, the wave travels 5 m.
In general,
S
p

d
=
distance
time
In applying this general definition of speed
↑
to a wave, we have
speed of the wave
=
wavelength
period
Note: we generally use v for speed of a wave. Using the variable names, then that last formula is written
v
=
λ
T
Since
T
=
1
f
, we can also say that
v
=
λ
⋅
f
So, using that last formula
v
=

s
Note: the unit Hz is equivalent to what it was called 100 years ago,
cycles
second
(
also cps
)
. Cycles is not a true unit, so the Hz contributed only the "per second" to the result
15

Answer:
Mass of the wooden Block is 20g.
Explanation:
The buoyant force equation will be used here
Buoyant Force= ρ*g*1/2V Here density used is of water
m*g= ρ*g*1/2V
Simplifying the above equation
2m= ρ*V Eq-1
Also we know from the question that
ρ*V = m + 0.020 Eq-2 ( Density = (Mass+20g)/Volume )
Equating Eq-1 & Eq-2 we get
2m = m+0.020
m = 0.020kg
m = 20g
