Answer: Artificial Selection

Explanation: Artificial Selection is described as the identification of desirable traits in both plants and animals, then enhance them, so that those traits can be manifested in future generations.

This is the scope behind cross breeding of plants and animals and this have largely been used in agricultural sector to improve input (such as disease-resistant seeds) and other biotechnological settings.

Darwin's described artificial selection as the human form of natural selection.

A force does work on an object if a component of the force is called
ivanzaharov [21]

Explanation:

The work done by an object is given by :

W=Fd\cos \theta

Here,

F is force

d is displacement

\theta is the angel between F and d.

If the angle between force and displacement is 0, then the work done is equal to, W=Fd.

So, a force does work on an object if a component of the force is parallel to the displacement of the object.

A 75kg man goes up a tower 30 m in 120s. How much power did the man exert
Pepsi [2]

Explanation:

If g= 10m/s²

Then 75kg=75×10=750N

Since Work =Force ×Distance

Work=750×30

=22500J

And Power°=Work÷time

=22500÷120

=187.5W

What is the kinetic energy of a 145 g baseball moving at 42 m/s?
klio [65]
Answer:
Kinetic energy = 127.89 Joules

Explanation:
Kinetic energy is calculated using the following rule:
KE = (1/2)*v* v^2
Where:
m is the mass = 145 g = 0.145 kg
v is the velocity = 42 m/sec

Substitute in the above equation to get the kinetic energy as follows:
KE = (0.5)(0.145)(42)^2
Kinetic energy = 127.89 Joules

Hope this helps :)
