Engineers are trying to improve a race car. Their goal is to increase the acceleration of the car using the same engine. Which c
noname [10]

Decreasing the mass of the car will help increase the acceleration of the car using application of Newton’s laws of motion.

<h3>What is Newton's law of motion?</h3>

This law discusses the relationship between motion of a substance and the forces acting on it.

Heavy objects are more difficult to move which is why decrease in mass will help increase the acceleration.

Marina86 [1]

Answer:

Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. ... As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

in terms of the wavelength of the sound wave, about how far below the open end of the resonance tube is the first resonant posit
notka56 [123]

The first resonant position below the open end of the resonance tube is; <em><u>one-quarter of the wavelength</u></em>

In the event of the first resonant position in a resonance tube, there will be a maximum air displacement which is only one antinode right at the open end where the motion is constrained.

However, there will be no displacement at the closed end which means another one node right at the closed end where air is halted.

This means that the standing wave will have one-quarter of the wavelength in the test tube.

Thus;

L = ¼λ

A TV is rated at 0.1 kW. This TV is used 3 hours per day. How much energy does the TV use per month (in kWh)?
exis [7]

Answer:

<em><u>A.9</u></em><em><u> </u></em><em><u>kWh</u></em>

Explanation:

Tv is rated 0.1 kW

in one day energy used will be 0.1kW ×3hr=0.3kwh

in 30 days energy used will be 0.3kwh×30=9kwh
