Compared to the emitted radio waves, the radio waves reflected from the vehicle and received by the radar gun have a<u> higher frequency.</u>
<u></u>
<h3>What is the frequency?</h3>
Frequency is defined as the number of repetitions of a wave occurring waves in 1 second. Its unit is Hz. Frequency is given by the formula as,
A moving car is targeted by radio waves sent from a radar gun by a police officer standing still.
The radio waves reflected off the vehicle and picked up by the radar gun have a greater frequency than the radio waves that were transmitted.
A stationary police officer directs radio waves emitted by a radar gun at a vehicle moving toward the officer.
Compared to the emitted radio waves, the radio waves reflected from the vehicle and received by the radar gun have a<u> higher frequency.</u>
Hence the higher frequency is the correct answer for blanks.

Answer:
planes, whereas the Oort cloud of comets has a spherical distribution.
Explanation:
A planet can be defined as a large celestial body having sufficient mass to allow for self-gravity and make it assume a nearly circular shape (hydrostatic equilibrium), revolves in an orbit around the Sun in the solar system and has a cleared neighborhood.
Basically, the planets are divided into two (2) main categories and these includes;
I. Outer planets: these planets are beyond the asteroid belt and comprises of jupiter, saturn, uranus and neptune, from left to right of the solar system.
II. Inner planets: these planets are the closest to the sun and comprises of mercury, venus, earth and mars.
These outer planets are made mostly of gases (hydrogen and helium) causing them to be less dense than the solid inner planets. These gases are generally known to be less dense in terms of physical properties.
Oort cloud is also referred to as Opik and it typically comprises of icy pieces of planetesimals (space debris) that spherically surrounds the sun at distances ranging from about 3000 to 100,000 AU.
Hence, the planets and the asteroid belt orbit the Sun in planes, whereas the Oort cloud of comets has a spherical distribution.

Answer:
By Newton's law Friction= -62.5N
Explanation:
Applying second law of Newton (which is the the sum of the forces is equal to the mass of the object who feels the forces times the acceleration)
<em>Push</em>+<em>Friction</em>=
Which indicates that the friction is opposed to the push and it is really appreciable, that is to say, there is a lot of friction between the box and the floor.
