I would make a flying car
SVEN [57.7K]3 years ago
4 0

Answer:

I would add a higher center of gravity, and make the car shaped in a way where wind could hit it, and the wind won't affect the car's movement whatsoever.

Explanation:

A higher center of gravity ensures that your car will take less effects from the wind, and the shape would make it barely noticeable.

Photovoltaic solar cells are:
nata0808 [166]

Answer:

c) wafers of crystalline silicon treated with metals that absorb solar radiation and generate electricity

Explanation:

Photovoltaic solar cells are used in solar panels. Most of the photovoltaic cells are made from crystalline silicon.

It has a property using which it converts the light (solar radiation) falling on it to electrical energy. This process occurs due to the photovoltaic effect.

It is a way generating energy without consuming fossil fuels. Thus it reduces the carbon emission and thus plays a major role in environment protection.

A train is traveling away from you at 120 km/h. it blows its whistle, and you hear a tone of 0.400 kHz. Take the speed of sound
Vaselesa [24]

Answer:B)439.21 Hz

Explanation:

Given

velocity of train v=120 km/h\approx 120\times \frac{5}{18}=33.33 m/s

frequency of train f_a=0.400 kHz\approx 400 Hz

speed of sound c=340 m/s

frequency from Doppler effect can be calculated by

f_a=(\frac{c}{c+v})\cdot f

400=(\frac{340}{340+33.33})\cdot f

400=\frac{340}{373.33}\cdot f

f=400\times 1.098

f=439.21 Hz
