Well if we don't recycle paper and use it up too fast, more trees would be chopped down, which is not good for the environment. Plastic can be dangerous and release toxic chemicals so we have to handel it well. Btw, what grade are you in?
The one that help create radio waves is :
Changing electric and magnetic fields applied at right angles
Radio waves are transverse wave, which means that the oscillations occurring perpendicular to the direction of energy transfer
hope this helps
The de - acceleration of bullet from 360 m/s after it struck the tree trunk and was brought to rest is -152.54 x 10⁴ m/s².
<h3>What is Acceleration in Kinematics?</h3>
Acceleration is defined as the rate of change of velocity with respect to time. Mathematically -
<h3>a = Δv/Δt</h3>
Given is a bullet initially travelling at 360 m/s struck into a tree trunk 8.5 cm inside and comes to rest. From this, we can write
initial velocity [u] = 360 m/s
final velocity [v] = 0 m/s
distance travelled [d] = 8.5 cm = 0.085 m
The time span after which bullet comes to rest will be -
Δt = d/u
Δt = 0.085/360 = 2.36 x 10 ⁻⁴ seconds
a = Δv/Δt
Δv = 0 - 360 = - 360 m/s
a = (v - u)/Δt
a = - 360/(2.36 x 10 ⁻⁴)
a = - 152.54 x 10⁴ m/s²
Therefore, the de - acceleration of bullet from 360 m/s after it struck the tree trunk and was brought to rest is -152.54 x 10⁴ m/s².

The total force is the vector sum of the individual forces. The force from either electron has the same magnitude at the midpoint, but the directions of the forces are opposite, so the sum of the two forces is zero. I hope this helps! Thanks
