In an inelastic collision involving an isolated system, the final total momentum is

Aleksandr-060686 [28]

Answer: B) exactly the same as the initial momentum.

Explanation:

An inelastic collision occurs when the elements that collide remain together after the collision, and althogh the kinetic energy is not conserved because is transformed into other kinds of energy (thermal energy, for example), the linear momentum does.

This means the initial momentum before the collision will be equal to the final momentum after the collision:

$p_{o}=p_{f}$

Please i need your help w/h/w you make the following measurements if an object:42kg, and 22m

Rufina [12.5K]

Answer:

$1.9 kg/m^3$

Explanation:

The density of an object is given by

$d=\frac{m}{V}$

where

m is the mass of the object

V is its volume

In this problem,

m = 42 kg

V = 22 m^3

Substituting into the equation, we find the object's density:

$d=\frac{42 kg}{22 m^3}=1.9 kg/m^3$

Which is an example of something heated by conduction

hodyreva [135]

An example would be a pot on a stove. The radiation from the source of the heat (the stove) would make the handle hot by conduction from heat through contact.

Another example could be a metal spoon in a hot cup of coffee. The coffee itself is hot, but since the spoon is in the coffee and making contact, part of the spoon will become hot from the radiation of the source of heat (the hot coffee). Thus, conduction.
