Answer:
Total distance does the grasshopper travel before the cars hit is 150 m
Explanation:
Each car moves x=100 m before they collide. Both the cars moving in constant velocity. time taken t by each car is
where x is the distance traveled with velocity v
The insect is moving through this time period with a constant velocity of 15 m/s
The distance traveled by grasshopper is

Answer:
The pendulum frequency is (c) the same, or very close to it
Explanation:
The simple pendulum corresponds to a simple harmonic movement, to reach this approximation in the expression of the force the sine of the angle (θ) approaches an angle value, this is only true for small angles, generally less than 15º
Sine (15th) = 0.2588
The angle in radians is 15º π / 180º = 0.26180.2588 / 0.2618
The difference between these two values is less than 1.2%
for smaller angle the difference is reduced more
Therefore, the period for both the 5º and 10º angles is almost the same
According to the research, the correct option is true. Applying an electric current to the x-ray tube causes electrons to be boiled off the filament, producing x-rays.
<h3>What is the x-ray tube?</h3>
This is the part of the equipment that generates the X-rays, which consists of the electrons being accelerated to energies of 30 to 150 keV and hitting a tungsten target producing X-rays.
Specifically, it contains the cathode and the anode, which is covered by a protective and insulating casing, where the electrons emitted by a filament in the cathode reach the anode strongly accelerated, generating X-ray emission as a consequence, being the basis of all devices using ionizing radiation.
Therefore, we can conclude that according to the research, the correct option is true. Applying an electric current to the x-ray tube causes electrons to be boiled off the filament, producing x-rays.
