Which has the most kinetic energy from its motion?
victus00 [196]

Answer:

option c

Explanation:

K.E=1/2mv(squared)

K.E=1/2x900x80x80

K.E=450x6400=2880000J

convert to KJ=2880000/1000=2880KJ

In air, the 57 GHz radio wave has a shorter<br> wavelength compared to the 64 GHz radio wave.
dalvyx [7]

Answer:

False

Explanation:

Higher frequency signals have shorter wavelengths. Hence, the 64 GHz signal will have a shorter wavelength than the 57 GHz signal.

Frequency and wavelength are inversely proportional meaning as frequency increases wavelength decreases and as frequency decreases wavelength increases.

Cheers.

Which of the following vectors is equal to r⃗ AB?
alisha [4.7K]

<h3>Vector AB is equal to vector DC</h3>

<h3>Further explanation</h3>

Vector is a quantity that has a magnitude and direction.

A vector in a cartesian coordinate is represented by an arrow in which the slope of the arrow shows the direction of the vector and the length of the arrow shows the magnitude of the vector.

A position vector of a point is a vector drawn from the base point of the coordinates O (0,0) to that point.

The addition of two vectors can be done in the following ways:

\overrightarrow {AB} + \overrightarrow {BC} = \overrightarrow {AC}

A negative vector is a vector with the same magnitude but in opposite direction.

\overrightarrow {AB} = -\overrightarrow {BA}

Let's tackle the problem!

Two vectors are equal if they have the same magnitude and direction. In the attached picture, it can be clearly seen that the vector AB has the same magnitude and direction with vector DC. Therefore, vector AB is equal to vector DC.
