How does kinetic energy affect the stopping distance of a small vehicle compared to a large vehicle?
zhannawk [14.2K]
The equation for kinetic energy is KE=1/2mv^2
So if the small vehicle AND the large vehicle both had the same speed, the large vehicle would have more kinetic energy since it has greater mass, resulting in a much more larger stopping distance than the smaller car.

How does diet affect diabetes
lubasha [3.4K]

Answer:

A diet high in fat, calories, and cholesterol increases your risk of diabetes. A poor diet can lead to obesity (another risk factor for diabetes) and other health problems. A healthy diet is high in fiber and low in fat, cholesterol, salt, and sugar. Also, remember to watch your portion size.

Two wires, each of length 1.3 m, are stretched between two fixed supports. On wire A there is a second-harmonic standing wave wh
UNO [17]

Answer:

Explanation:

Given

Length of each wire L=1.3\ m

On wire A second harmonic frequency is given by

f_2_{a}=2\times (\frac{v}{2L})

where f=frequency

v=velocity of wave

L=length of wire

v_a=f_2\times L

v_a=640\times 1.3=832\ m/s

For wire B third harmonic is given by

f_3_{b}=3\times (\frac{v}{2L})

v_b=\frac{2L}{3}\cdot f_3_{b}

v_b=\frac{2\times 1.3}{3}\times 640=554.66\ m/s
