Which observation did researchers make in studies on separated twins ?

Physics

choli [55]3 years ago

Depending on whether they where conjoined initially, or where born separately really changes the answer of this question. Although studies show that twins generally have a kinetic link, more practical research says that twins are 25% more likely to both be left handed, which is a recessive gene, they are also more likely to die in child birth, twins are more likely to understand and be biligual, along with many other advantages twins may have.

If a hammer has a resistance arm of 3 inches and the effort arm is 15 inches. What is the mechanical advantage?
Sunny_sXe [5.5K]

Answer:

Option D

MA=5

Explanation:

Mechanical advantage is the  the ratio of the output force to the  input force hence

MA=\frac {Effort arm length}{Load arm length}

Substituting 15 inches for the effort arm length and 3 inches for the load arm length then we obtain the mechanical advantage as

MA=\frac {15}{3}=5

You have found that the net force exerted on the cylinder depends on several different independent variables in different ways.
postnew [5]

The net force on the cylinder depends on several independent variables such as mass, acceleration, velocity, time, etc, and it is given as F(net) = ma.

<h3>Net force exerted on the cylinder</h3>

The net force on the cylinder is calculated from Newton's second law of motion.

F(net) = ma

F(net) = m(v/t)

where;

  • m is mass of the cylinder
  • a is acceleration of the cylinder
  • v is velocity of the cylinder
  • t is time of motion of the cylinder

Thus, the net force on the cylinder depends on several independent variables such as mass, acceleration, velocity, time, etc, and it is given as F(net) = ma.

What is the wavelength of a wave with f = 0.9 Hz and v = 154.9 cm/s
Nataly_w [17]

Answer:

The wavelength of a wave is 1.72 m.

Explanation:

Given,

Frequency, f = 0.9 Hz

Speed of a wave, v = 154.9 cm/s = 1.549 m/s

The speed of a wave is given by :

v=f\lambda

\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{1.549\ m/s}{0.9\ Hz}\\\\\lambda=1.72\ m

So, the wavelength of a wave is 1.72 m. Hence, this is the required solution.
