A carpenter lifts a 10 kg piece of wood to his shoulder 1.5 m above the ground. What is the wood's potential energy on the carpe

nter's shoulder? (*Hint: "g" is the acceleration due to gravity of an object on Earth. G = 10 m/s^2)

Answer:

The wood's potential energy on the carpenter's shoulder is 150 J.

Explanation:

Given;

mass of the wood, m = 10 kg

height through which the wood was raised, h = 1.5 m

acceleration due to gravity, g = 10 m/s²

The  wood's potential energy on the carpenter's shoulder is calculated as;

P.E = mgh

P.E = 10 x 10 x 1.5

P.E = 150 J

Therefore, the wood's potential energy on the carpenter's shoulder is 150 J.

A soccer player kicks a ball with a force of 900 newtons. The ball has a mass of 0.5 kilograms. At what rate will the ball accel
Volgvan

Answer:

1800 m/s^{2}

Explanation:

We know this because of Newton's first law, F=ma, which shows us that the force on an object is equal to its mass times the acceleration it recieves. This means that taking our values of 900N and 0.5kg, and plugging them in,

900N=(0.5kg)*(1800m/s^2)

This is honestly a little strange because the force applied and the acceleration seem ridiculous, and a little strange for an answer. Either the values are not meant to be nearly close to reality, or you made a typo.

which of the numbers on this figure indicates typical continental conditions (regional metamorphism)?
Tpy6a [65]

The number that indicates typical continental conditions (regional metamorphism) is that showing schist and gneiss rocks.

<h3>What is regional metamorphism?</h3>

Regional metamorphism occurs when rocks undergoes changes as a result of high temperatures and pressure deep within the earth's crust.

Regional metamorphic rocks are usually foliated or squashed in appearance.

Examples of regional metamorphism rocks are schist and gneiss rocks.

Therefore, the figure that indicates typical continental conditions (regional metamorphism) is that showing schist and gneiss rocks.
