Answer: A. Proteins expressing color in butterfly wings mutate to create camouflaging abilities of butterflies.

Explanation:

Adaptation can be define as the changes occurring in living organisms in their physiology, morphology, and genomic. These adaptations allow organisms to survive in adverse environment.

A. is the correct option. It is an example of physiological adaptation. The color of butterfly wings will change due to protein expression. Thus help in camouflaging the predators by color change.

A 50kg boy runs at a speed of 10.0m/s and jumpsonto a cart

andriy [413]

Answer:

the mass of the cart is 150 kg

Explanation:

given,

mass of boy(m) = 50 kg

speed of boy (v)= 10 m/s

initial velocity of cart (u) = 0

final velocity of cart(V) = 2.5 m/s

mass of the cart(M) = ?

m v + M u = (m + M ) V......................(1)

50× 10 + 0 = (50 + M ) 2.5

M = $\dfrac{500}{2.5} - 50$

M = 150 Kg

hence, the mass of the cart is 150 kg

A 15g bullet is fired horizontally into a 3kg block of wood suspended by a long cord. Assume that the bullet remains in the bloc

Varvara68 [4.7K]

Answer:

261.3 m/s

Explanation:

Mass of bullet=m=15 g= $\frac{15}{1000}=0.015 kg$

1 kg=1000g

Mass of block=M=3 kg

d=0.086 m

Total mass =M+m=3+0.015=3.015 kg

K.E at the time strike=Gravitational potential energy at the end of swing

$\frac{1}{2}(m+M)^2V^2=(m+M)gh$

Using g= $9.8m/s^2$

Substitute the values

$\frac{1}{2}(3.015)V^2=3.015\times 9.8\times 0.086$

$V^2=\frac{2\times 3.015\times 9.8\times 0.086}{3.015}$

$V=\sqrt{2\times 3.015\times 9.8\times 0.086}}$

$V=1.3m/s$

Velocity after collision=V=1.3 m/s

Velocity of block=v'=0

Using conservation law of momentum

$mv+Mv'=(m+M)V$

Using the formula

$0.015v+3(0)=3.015(1.3)$

$0.015v=3.015(1.3)$

$v^2=\frac{3.015(1.3)}{0.015}=261.3$

$v=261.3 m/s$

Reflected light from a thin film of oil gives constructive interference for light with a wavelength inside the film of λfilm. By

My name is Ann [436]

Answer:D. λfilm/4

Explanation: Destructive interference is a type of wave interference which means the coming together or over-lapping of two opposing waves creating No effect or the Cancellation of the wave impact. An example of destructive wave is when Noise cancel the effect of sound from a head phone.

The film thickness will need to be increased by λfilm/4 for it to be able to give a destructive interference.
