Answer:

Rigid bodies: Options d and e

Rigid bodies' system: options f, g and h

Non-rigid bodies: Options a, b and c

Explanation:

The above classification of the mentioned objects into rigid bodies, non rigid bodies and system of rigid bodies can be explained as :

Rigid body: A body which does not undergo any change in its form or shape on application of externally applied load or force is said to be a rigid body.

System of Rigid bodies:

A system of rigid bodies is different from any other element system as in this the bodies constituting the system must be rigid bodies.

Non-rigid bodies:

A body which undergoes a change in its form or shape on application of externally applied force or load is said to be a non-rigid body.

Two objects are moving at equal speed along a level, frictionless surface. the second object has twice the mass of the first obj

lbvjy [14]

Answer:

They both rises to same height.

Explanation:

When an object is sliding up in friction less surface than according to conservation of energy its potential energy will be converted into kinetic energy.

$mgH=\frac{1}{2}mv^{2}\\ v=\sqrt{2gH}$

Here, m is the mass, v is the velocity, g is the acceleration due to gravity and H is the height.

Here the height is independent on the mass of an object and its only depend on velocity.

Now according to the question, two objects have same velocity but they have different masses.

Therefore, they rises to the same height because height will not change with mass.

A small airplane flies 780 miles with an average speed of 260 miles per hour. 1.5 hours after the plane leaves, a Boeing 747 lea

Lera25 [3.4K]

Answer:

520 miles per hour

Explanation:

Let the speed of the Boeing 747 be x miles per hour.

The small airplane covers distance of 780 miles with speed 260 miles per hour.

Also,

After 1.5 hours the Boeing 747 leave the same place and reaches at same time. Both covered distance of 780 miles.

So,

Time taken by Boeing 747 + 1.5 hours = Time taken by small plane.

Also,

Time = Distance/ speed

So,

780 / x + 1.5 = 780/ 260

Solving for x, we get:

x = 520 miles per hour
