When unbalanced forces act on an object, __________________. the object accelerates friction becomes greater than the net force the objects speeds up the net force is zero?

Answers

Answer 1

Answer:

When an unbalanced force acts on an object, the object accelerates. We can immediately rule out B and D, as friction changes based on the material and by applying a force the net force can’t be zero. It can be easy to say that the object will speed up after the force is applied (and it often does!), but take a braking car, for example. An external force of friction is applied to the brakes, causing an acceleration but in such a fashion that the car slows down. So, although an object can speed up after a force is applied, it isn’t always guaranteed.

Hope this helps!

Which type of radio waves have the highest frequency and are used in radar detection? microwaves x-rays waves infrared waves gamma waves

Answers

Answer: Microwaves

Explanation:

RADAR stands for radio detection and ranging. Radio waves range from 300 GHz to 30 Hz. Modern radar uses higher frequency of waves for detection. These waves are microwaves (300 MHz-300 GHz). Microwaves are types of radio waves and are used in the radar detection.

The electromagnetic wave which has highest frequency is gamma wave but it is not used for radar detection.

Hence, the correct answer is microwaves are the type pf radio waves which have the highest frequency and are used in radar detection.

microwaves are a type of radio waves used in radar detection and they have the highest frequency.

Two waves are superposed. One wave has an amplitude of 3 cm, and the other has an amplitude of 4 cm. What is the resultant amplitude?

Answers

The sum (or difference) of two solutions of the wave equation is again a solution of the wave equation(superposition principle)

therefore the amplitude of resultant wave is 3+4= 7cm

Answer:

7 cm

Explanation:

When the waves are super-posed their amplitudes are added algebraically to get the resultant amplitude.

resultant amplitude = 3+4 = 7cm

Air pressure is gravity pulling down on air molecules.
a. True
b. False

Answers

Air pressure is gravity pulling down on air molecules. Like us,air has also mass and the pressure is brought down by the earth’s gravitycausing an increase in weight exerted on you as you descend lower into theatmosphere. So, as you enter into the other layers of atmosphere above the troposphere,the air pressure starts to decrease. Below the atmosphere is the hydrosphere. This iswhere all liquid forms are located. And since the seawater has a greater massthan air, it has the greatest pressure. The answer is true.

Answer:

true
