A 0.017-kg acorn falls from a position in an oak tree that is 18.5 meters above the ground.

Marianna [84]

Answer:

Part a)

Final speed of the corn is 19.05 m/s

Part b)

Kinetic energy of the corn is 3.1 J

Explanation:

Part a)

As we know that the initial position of the corn is

h = 18.5 m

now we also know that it will fall from rest and moving under constant acceleration so we will have

$v_f^2 - v_i^2 = 2 a d$

$v_f^2 - 0 = 2(9.81)(18.5)$

$v_f = 19.05 m/s$

Part b)

Kinetic energy of the corn is given as

$K = \frac{1}{2}mv^2$

$K = \frac{1}{2}(0.017)(19.05)^2$

$K = 3.1 J$

Name:

aliya0001 [1]

Answer:

Kinetic energy is 1000 J.

Explanation:

Given:

Mass of the bicycle, $m=80\textrm{ kg}$

Distance traveled, $d=100\textrm{ m}$

Time of travel, $t=20\textrm{ s}$

Unknowns:

Speed of the bicycler, $v$ .

Kinetic energy of the bicycler.

Equation:

Speed of the bicycler is, $v=\frac{d}{t}=\frac{100}{20}=5\textrm{ m/s}$

Therefore, the kinetic energy of the bicycler is given as,

$KE=\frac{1}{2}mv^{2}$

Substitute:

Plug in 5 m/s for $v$ and 80 kg for $m$ . Solve for KE.

Solve:

$KE=\frac{1}{2}\times 80\times (5)^{2}\\KE=40\times 25=1000\textrm{ J}$

Therefore, his kinetic energy is 1000 J.

What causes convection in the Earth's mantle layer?

Serggg [28]

The mantle is heated in the core, where it is hotter it is more buoyant, whereas in areas where it is cooler it is less buoyant. This results inconvection cells in the mantle, and produces horizontal motion of mantle material close to the Earth surface.

Which section of the reaction represents the reactants? A) a B) b C) c D) d

ivann1987 [24]

This question is incomplete, but I can do it for you, considering the equation to be *In its most famous form*:
A+B⇒C+D
A and B here are the reactants, while C and D are the products.
The reactants are generally the input materials in the beginning of any chemical reactions and they usually, if not always, are on the left hand side of the chemical equation. While the products are on the right hand side and are the final output of the chemical reaction.

Hope this helps.
