Which are characteristics of electromagnetic waves? Check all that apply.

.

Waves with a higher frequency have a shorter wavelength.

Answer:

The correct answers apply:

B)

D)

E)

Explanation:

B) Given that all electromagnetic waves pass through space at the same speed, a wave with a shorter wavelength must have a higher frequency, and vice versa. This relationship is depicted in the equation below:

                               <em>Speed = Wavelength × Frequency</em>

D) & E) All electromagnetic waves travel through empty space at the same speed. The speed, which is called light speed, is around 300 million meters per second (3.0 x 108 m / s). There's nothing else known in the universe that moves at this speed.

Cheers!

Which of the following BEST explains why stability is an important skill for athletes?
Irina-Kira [14]

Answer;

B. Without good stability, athletes are too clumsy to perform well.

Explanation;

Stability refers to the resistance to both linear and angular acceleration, or resistance to disruption of equilibrium.

Developing and enhancing core strength and stability helps athletes to maximize their power output and enhance game day performance. Additionally, Improving core strength and stability can also help athletes reduce their risk of injury.

A rocket fired two engines simultaneously. One produces a thrust 725 N directly forward while the other gives a 513N thrust at 3
dezoksy [38]

Answer:

Magnitude of resultant force is  1190.314 N

Direction of force is 13.352°

Explanation:

given data:

thrust force = 725 N

Angle = 32.4 degree

Let x is consider as positive direction

Resultant force in x direction is  

Rx = 725 + 513cos32.4 = 1158.14 N

and Resultant force perpendicular to x direction is:

Ry = 513sin32.4 = 274.88 N

Magnitude of resultant force is

R=\sqrt{R_x^2+R_y^2} = 1190.314N

and resultant force direction is  

\theta=tan^{-1}\frac{R_y}{R_x} = 13.352\degree

When does an object possess mechanical energy?
mel-nik [20]
Objects have mechanical energy if they are in motion and/or if they are at some position relative to a zero potential energy position (for example, a brick held at a vertical position above the ground or zero height position). A moving car possesses mechanical energy due to its motion (kineticenergy).

Which of the following are basic principles that apply to circuits? Choose the 2 correct answers from the choices below.
marta [7]

The basic principles that apply to circuits is that electrons must receive energy from a source, and electrons transfer energy to perform some useful function.

<h3 /><h3>What is circuit?</h3>

Individual electronic components, like resistors, transistors, are connected by metallic wires or traces by which the electric current can flow to form a circuit design.

The basic principles that apply to circuits will be;

1. Electrons must receive energy from a source.

2. Electrons transfer energy to perform some useful function.

Hence, option 1 and 2 are correct.
