Answer:
Energy
Explanation:
A wave is a kind of disturbance which passes through a medium and during this process, energy is transferred from one point to another without causing any permanent displacement to the medium itself.
for example if a stone is dropped inside water, circular ripples are observed and energy moves from one point to another .
Answer:
F = 2349.6 N
Explanation:
We can solve this exercise using the relationship of momentum and momentum
I = Δp
I = F t
As the woman accelerates at a distance of 29.1 m to go from rest to 56.8 m / s, we can use the kinematics to find the acceleration
v² = v₀² + 2 a x
v₀ = 0
a = v / 2x
a = 56.8 2/2 29.1
a = 55.43 m / s²
Let's look for the time you need to get this speed
v = v₀ + a t
t = v / a
t = 56.8 / 55.43
t = 1,025 s
Let's clear the average force momentum from the momentum
F t = m v- m v₀
F = mv / t
F = 42.4 56.8 / 1.025
F = 2349.6 N
Answer:
x=7227
y=1678
(7227,1678)
Explanation:
Ok, check the picture I attached you, because of the problem don't give us aditional information, let's asume that the projectile is fired from an initial position x=0 and y=0. Now let's use projectile motion equations, but firs let's find the initial velocity components in x-axis and y-axis:
Now, let's find the x coordinate with this equation:
Finally asumming a gravity constant g=9.8, let's find the y coordinate with the next equation:
Answer:
Not all of the time, it can also depend on the strength of the magnet.
Explanation:
say you have a small very strong magnet, that might work just as well as a large but week magnet.
The right answer for the question that is being asked and shown above is that: "<span>B: 156 kPa ." </span>Marshall determines that a gas has a gage pressure of 276 kPa whats the absolute pressure of this gas <span>B: 156 kPa </span>
