Answer:
When something is transparent, it means that it allows light to pass through or is see-through . For example:
1) glass
2) air
3) some plastics
Answer:
Work, W = F * d, and
Work = change in kinetic energy, so W=deltaKE.
Hence,
deltaKE=F * d
(1/2)*m*v^2 =F * d
d=[(1/2)*m*v^2]/F
d=[(1/2)*0.6*20^2]/5
d=24 m.
Explanation:
Work = change in kinetic energy, so W=deltaKE.
Answer:
If it has more electrons than protons it has a net negative charge and is known as an anion.
Answer:
Explanation:
the one thrown below the horizontal is going straight down, while the one above the horizontal will experience a projectile motion which will makes it move farther away from the building where it was projected.
The average force is -212.4 N
Explanation:
We can solve this problem by using the impulse theorem, which states that the impulse exerted on the object (the product of the force exerted and the time) is equal to the change in momentum of the object:
![F \Delta t = m \Delta v](https://tex.z-dn.net/?f=F%20%5CDelta%20t%20%3D%20m%20%5CDelta%20v)
where
F is the net force on the object
is the time
m is the mass
is the change in velocity
In this problem, we have:
m = 26.3 kg
![\Delta t = 2.60 s](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%202.60%20s)
Solving for F, we find
![F=\frac{m\Delta v}{\Delta t}=\frac{(26.3)(-21.0)}{2.60}=-212.4 N](https://tex.z-dn.net/?f=F%3D%5Cfrac%7Bm%5CDelta%20v%7D%7B%5CDelta%20t%7D%3D%5Cfrac%7B%2826.3%29%28-21.0%29%7D%7B2.60%7D%3D-212.4%20N)
where the negative sign indicates that the direction of the force is opposite to the motion of the object.
