<span>the transverse wve that requires a medium to move is : sound waves
in order to travel, sound waves need to jumped on between one particle to another, no matter it's liquid, solid , and gases. Which explains why you wont hear a thing in outer space, simply because the sound waves got no particle to jumped into</span>
Answer:
2,
Explanation:
Because one eye can see small area, having two will give your eyesight a bigger AoE (wider area)
Answer:
65 N
Explanation:
ΣForces = (mass)(acceleration) = all other forces being enacted
The force that the rope exerts is just the tension in the rope caused by the bucket being lifted. I'll take up to be positive and down to be negative, so the tension is an upward force vector and the bucket weight is a downward force vector. By taking into account all the forces involved here, we get the formula:
ΣForces=ma=Tension-mg
- m is the bucket mass
- g is gravity pulling down on the bucket, I'm also taking gravity as 10m/s²
- a is the upward acceleration of the bucket
By isolating Tension we get Tension=ma+mg
Tension = m(a+g)
Tension = 5kg(3+10)m/s²
Tension = (5)(13)N
Tension = 65N
<span>If your speed change from 10 km/h to 6 km/h,you have a negative acceleration</span>
The answer is A for this one
