Answer:

The answer would be A.

Explanation:

"There are gender differences in body shape and composition that are essential for reproductive function. There are also physiological differences between males and females, such as levels of different hormones. Because of these differences, it can be harder to females to lose body fat and gain muscle than it is for males."

Find the wavelength (in nm) of a 2.52 eV photon. a. 492.34127 nm.b. 585.88611 nm.c. 541.5754 nm.d. 418.49008 nm.
elena-14-01-66 [18.8K]

Answer:

The correct option is (a).

Explanation:

Given that,

The energy of photon, E = 2.52 eV

We need to find the wavelength of the photon in nm. The formula for the energy of a photon is given by :

E=\dfrac{hc}{\lambda}\\\\\lambda=\dfrac{hc}{E}\\\\\lambda=\dfrac{6.63\times 10^{-34}\times 3\times 10^8}{2.52\times 1.6\times 10^{-19}}\\\\=4.93\times 10^{-7}\ m\\\\=493\ nm

The nearest option is a) i.e. 492.34127 nm.

what is the net force required to give an automobile with a mass of 1,600 kg an acceleration of 4.5m/s
Dmitrij [34]

Hi there!

Recall Newton's Second Law:

\large\boxed{\Sigma F = ma}}

∑F = Net force (N)

m = mass (kg)

a = acceleration (m/s²)

We are already given the mass and acceleration, so we can plug these values into the equation:

∑F = 1600 · 4.5 = 7200 N

An object has a mass of 14 grams and a density of 7 g/mL. When placed in water it sinks. What is the Volume of water displaced?
iVinArrow [24]

Explanation:

D = M/V

We rearrange this equation to get V = M/D

So 14 g/7 g/mL,

the grams cancel out, and we're left with 2 mL.

D is the answer.

Bogdan [553]

Answer:1.53g

Explanation:

average deceleration= ?

inial velocity: u=0

final velocity: v=30m/s

time: t=2seconds

The first law of kinematics :

v=u+at

find a the subject of the formula

a=v-u/ t

a=\frac{0-30} 2

a=-30/2

a=-15m/s^{2}

The deceleration about g(acceleration due to gravity) will be:

15/9.8

1.53g
