Answer:
294 J
Explanation:
To find the kinetic energy (KE) of a 3.00 kg toy falling from a height of 10.0 m, we'll use the kinetic energy formula: KE = 0.5 * m * v^2, where 'm' is the mass of the toy, and 'v' is its velocity.
We'll also apply the conservation of energy principle, which states that the total energy of an isolated system remains constant. This means that the gravitational potential energy (PE) of the toy at the initial height is equal to its kinetic energy just before hitting the ground.
The formula for gravitational potential energy is PE = m * g * h, where 'm' is the mass of the object, 'g' is the acceleration due to gravity, and 'h' is the height of the object.
So, we can equate these two expressions and solve for 'v':
0.5 * m * v^2 = m * g * h
v^2 = 2 * g * h
v = √(2 * g * h)
Plugging in the given values:
v = √(2 * 9.8 m/s² * 10.0 m)
v ≈ 14.0 m/s
Now that we have the velocity of the toy, we can calculate its kinetic energy using the KE formula:
KE = 0.5 * m * v^2
KE = 0.5 * 3.00 kg * (14.0 m/s)^2
KE ≈ 294 J
So, just before hitting the ground, the kinetic energy of the toy is approximately 294 joules.
Answer:
Emphasizes
Explanation:
The expression of an art is intelligible to those that understand it, as such to make an impression an artist has to emphasize the point they want to communicate
An art is an expression of the personal experiences of the artist or a reaction to events or to reveal the realities as seen by the artist such as global warming and the environment, so as to get the attention of people with the goal to change them, such that a good art changes the most people, hence the need for emphasis.
Answer:
A - emphasizes
Answer:
Vesicular texture refers to volcanic rocks that contain holes called vesicles that were formed by gas bubbles in lava. This igneous rock is called scoria. The vesicles form from escaping gas bubbles in cooling lava.
