A bowling ball of 35.2kg, generates 218 kg.m/s units of momentum. What is the velocity of the bowling ball?

KIM [24]

Answer:

6.19m/s

Explanation:

Given parameters:

Mass of bowling ball = 35.2kg

Momentum = 218kgm/s

Unknown:

Velocity of the bowling ball = ?

Solution:

Momentum is the quantity of motion a body possess;

Momentum = mass x velocity

218 = 35.2 x velocity

Velocity = 6.19m/s

When you mix a solution, the mass of the substances before and after you mix them should be the same.true or false

Leya [2.2K]

Answer:

True

Explanation:

The mixing substances can be taken to be the reactants and the resulting mixture as the product. When the substances change state during mixing, the mass of the substances does not change meaning that the mass of the product will equal the mass of the reactants .This is true due to the law of conservation of mass.

Matthew drives 10 meters to go to the park at her the park he goes to the movie theatre which is 15 meters away from the park. H

Step2247 [10]

Answer: 0 m

Explanation:

Let's begin by stating clear that movement is the change of position of a body at a certain time. So, during this movement, the body will have a trajectory and a displacement, being both different:

The trajectory is the <u>path followed by the body</u> (is a scalar quantity).

The displacement is <u>the distance in a straight line between the initial and final position</u> (is a vector quantity).

According to this, in the description Matthew's home is placed at 0 on a number line, then he moves 10 m to the park (this is the distance between the park and Mattew's home), then 15 m to the movie theatre until he finally comes back to his home (position 0). So, in this case we are talking about the <u>path followed by Matthew</u>, hence <u>his trajectory</u>.

However, if we talk about Matthew's displacement, we have to draw a straight line between Matthew's initial position (point 0) to his final position (also point 0).

Now, being this an unidimensional problem, the displacement vector for Matthew is 0 meters.

If someone said that instruments that produce sounds by vibrating themselves are called aerophones, would that be a true or fals

AfilCa [17]

If someone said that instruments that produce sounds by vibrating themselves are called aerophones. <u>False</u>

<h3>What is aerophones?</h3>

An aerophone is a musical instrument that makes sound primarily by forcing a body of air to vibrate without the use of strings or membranes, and without the vibration of the instrument itself significantly enhancing the sound.

<h3>What is aerophone instrument?</h3>

Any of a group of musical instruments known as aerophones, in which the initial sound is produced by a mass of vibrating air. Instruments that don't fit into any of these categories, such the bull-roarer and the siren, are also included in the basic types, along with woodwind, brass, and free-reed instruments.

<h3>What are African aerophones?</h3>

Aerophones, which create music by vibrating columns of air, are among the instruments used in Africa. Flutes, reed pipes, and trumpets and horns are the three major types of African aerophones.
