Answer:

Option D. Weight varies with location, but mass does not.

Explanation:

To know which option is correct, it is important that we have a background knowledge of mass and weight.

A brief summary of the difference between mass and weight is given below:

1. Mass is the quantity of matter present in an object while weight is the gravitational pull on an object.

2. The SI unit of mass is kilogram Kg) while that of weight is Newton (N)

3. Mass is constant while weight varies by location.

4. Mass can measured using a chemical balance or beam balance while weight can be measured using a lever or spring balance.

With the above information, we can see that mass of an object is always but the weight varies by location.

What newton equal to in terms of units of mass and acceleration

Korvikt [17]

This equation is one of the most useful in classical physics. It is a concise statement of Isaac Newton's Second Law of Motion, holding both the proportions and vectors of the Second Law. It translates as: The net force on an object is equal to the massof the object multiplied by the acceleration of the object.

The outside edge of a spinning compact disc is moving at a higher velocity than an inside track on the disc.

Serjik [45]

Answer:

The outside edge of a spinning compact disc moves with a higher velocity than the inner track of the disc.

Explanation:

Here the compact disc undergoes rotational motion about a fixed axis which is its centre in this case. The particles in rotational motion have angular velocity which is given by the equation

ω = ∅/t

Where θ is the angular displacement and t is the time.

The transnational speed of a particle which is in circular motion is given by the equation

v = rω

r is the distance of the point from the rotation centre

The transnational speed of the particles is merely determined by their distance from the centre in this case. It is due to the equality of angular velocity of all the points.

The distance of the outer edge of the compact disc from its rotational centre is larger than the distance of inner edge from the rotational centre. Thus the farther edge of a spinning disc moves faster than the nearer edge.

The mass of the basketball shown below is 4 times the mass of the baseball.

igomit [66]

Answer:

<h3>40.0 Joules. None of the answers is correct</h3>

Explanation:

Kinetic energy of an object is expressed as;

KE = 1/2mv² where;

m is the mass of the object

V is the velocity of the object.

Let Ma be the mass of the basketball and Mb be the mass of baseball.

If the mass of the basketball shown below is 4 times the mass of the baseball, then Ma = 4Mb

KE of the basket ball = 1/2MaVa²

Va² = 2(KE)a/Ma ...... 1

KE of the baseball = 1/2MbVb²

Vb² = 2(KE)b/Mb .......... 2

Since their velocities are the same, hence Va²= Vb²

2(KE)a/Ma = 2(KE)b/Mb

Substituting Ma = 4Mb into the resulting expression.

2(KE)a/4Mb = 2(KE)b/Mb

2(KE)a/4 = 2(KE)b

Given Kinetic energy of baseball (KE)b = 10.0J, the expression becomes;

2(KE)a/4 = 2(10)

2(KE)a = 4*20

2(KE)a = 80

(KE)a = 80/2

(KE)a = 40.0J

Hence the kinetic energy of the basketball is 40.0Joules
