Karolina [17]3 years ago
4 0

Explanation:

The kinetic energy is basically the energy possesses by virtue of a body's motion

1. The truck moving to the quarry

let the mass be x

and the velocity is given as 20m/s

we know that the kinetic energy is given as

KE=1/2mv^2

KE=1/2(x)*20^2

KE=1/2(x)400

KE=200x

2. The truck leaving to the quarry

let the mass be 2x

and the velocity is given as 20m/s

we know that the kinetic energy is given as

KE=1/2mv^2

KE=1/2(2x)*20^2

KE=1/2(2x)400

KE=400x

From the analysis the kinetic energy is a function of mass, doubling the mass doubles the kinetic energy

If distance between two charges increased by 2 times then force
kati45 [8]

Explanation:

The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value.

Verizon [17]

Answer:

The answer is "1.144 \times 10^{-4} \ m".

Explanation:

w=\frac{2.44 \lambda L}{D}\\\\D=\frac{2.44 \lambda L}{w}\\\\

   =\frac{2.44 \times 633 \times 10^{-9}\times 4 }{0.054}\\\\=\frac{6178.08\times 10^{-9}}{0.054}\\\\=1.144 \times 10^{-4} \ m

Which of the below is an example of mimicry that enables prey species avoid predation?
Marta_Voda [28]

b..a harmless organism imitating the look of a harmful organism

Explanation:

A harmless organism imitating the look of a harmful organism is one example of mimicry that enables prey species avoid predation.

Prey are smaller and less harmful organisms often hunted by larger organisms usually carnivores.

Mimicry is a form of evolutionary adaptation process in which two organisms of the same specie or different species tends to look alike.

It is a subtle defense mechanism developed by organism over an extended period of time.
