Which of the following best compares longitudinal waves with transverse waves?

Semmy [17]

In longitudinal waves, the particles of the medium or a system displaces back and forth(parallel) in the direction of the propagation of waves. In transverse waves, the particles of the medium or a system displaces perpendicular to the direction of the propagation of waves. Therefore, C is correct.

How would i solve these problems, nobody in my class understands and there is a substitute

DiKsa [7]

1) X-component: 568.5 N, Y-component: 511.9 N

2) The horizontal force is 86.6 N and the resulting acceleration is $0.87 m/s^2$

Explanation:

In this first part of the problem, we have to resolve the force into its two components, along the x and the y direction.

The two components are given by:

$F_x = F cos \theta\\F_y = F sin \theta$

where

F = 765 N is the magnitude of the force

$\theta=42.0^{\circ}$ is the angle of the force with the horizontal

Substituting, we find:

Horizontal component: $F_x = (765)(cos 42.0^{\circ})=568.5 N$
Vertical component: $F_y = (765)(sin 42.0^{\circ})=511.9 N$

First of all, we have to find the horizontal component of the pulling force, which is given by

$F_x = F cos \theta$

where

F = 100 N is the magnitude of the pulling force

$\theta=30.0^{\circ}$ is the direction of the force with the horizontal

Substituting,

$F_x = (100)(cos 30^{\circ})=86.6 N$

Now we can find the acceleration of the wagon by using Newton's second law:

$F_x = ma_x$

where

$F_x = 86.6 N$ is the net force in the horizontal direction

m = 100 kg is the mass of the wagon

$a_x$ is the acceleration in the horizontal direction

Solving for $a_x$ , we find

$a_x = \frac{F_x}{m}=\frac{86.6}{100}=0.87 m/s^2$

What is the total resistance of the circuit? (must include unit - ohms) I WILL GIVE BRAINLIEST!

ICE Princess25 [194]

Answer: 4 ohms

Explanation:

For parallel connection we use this formula

R=equivalent resistance

R1=24 ohms

R2=8 ohms

R3=12 ohms

1/R=1/R1 + 1/R2 + 1/R3

1/R=1/24 + 1/8 + 1/12

1/R=(1x1+3x1+2x1) ➗ 24

Cross multiplying we get

24x1=(1x1+3x1+2x1) x R

24=(1+3+2) x R

24=6xR

Divide both sides by 6

24 ➗ 6=6xR ➗ 6

4=R

R=4 ohms

As you take the stoppered part of the tube up the staircase you begin to see the water level drop around the 4th floor. As you c

Tom [10]

Answer:

a. The pressure in the tubing is equal to the barometric pressure.

Explanation:

Since in the question it is mentioned that the if you take the stoppert part of the tube than the level of warer would be fall approx 4th floor and if it is continued than it wont be continue but remains constant.

Now here first we do that the tube i.e. connected to the bucket should be taken up. In the first instance, the bucket supplies the water to the tube but it would not increased far away to the level of the barometric pressure

Hence, the correct option is a.

A 2kg chunk of putty moving at 5 m/s collided with and sticks to a 3kg medicine ball initially at rest. What is the momentum of

skad [1K]

Answer:

10 kg.m/s

Explanation:

Momentum is a product of mass and velocity, expressed as p=mv where m is the mass of an object, v is the velocity of an object and p denote momentum.

The principle of linear momentum states that the sum of momentum before and after collision are always equal.

Given mass of initially as 2kg and its velocitu as 5kg and taking forward direction as positive.

Momentum before collision will be

P=2kg*5m/s=10 kg.m/s
