Answer:

Momentum of object A = Momentum of object C < momentum of B.

Explanation:

The momentum of an object is equal to the product of mass and velocity.

Object A has a mass m and a speed v. Its momentum is :

p = mv

Object B has a mass m/2 and a speed 4v. Its momentum is :

p = (m/2)×4v = 2mv

Object C has a mass 3m and a speed v/3. Its momentum is :

p = (3m)×(v/3) = mv

So,

Momentum of object A = Momentum of object C < momentum of B.

How is silver, gold, and bronze different.
joja [24]

Answer:

Silver is a malleable and ductile metal having atomic number 47 and symbol Ag. Gold on the hand has atomic number 79 and symbol Au. It is also ductile and malleable. Both are soft and lustrous in nature. Both are transition metals.

Bronze is an alloy of majority of copper and some amount of tin.  Formation of alloy enhances the properties of the metal and its industrial use. Bronze is harder than copper and easily fusible and easy to cast. It is resists corrosion.

Silver and gold have different atomic numbers, different colors. Both are transition elements where as Bronze is an alloy.

What is the change in velocity of a 22-kg object that experiences a force of 15 N for
vagabundo [1.1K]

Answer:

Force = mass × acceleration

Acceleration:

{ \tt{15 = (22 \times a)}} \\ { \tt{a =  \frac{15}{22}  \:  {ms}^{ - 2} }}

From first Newton's equation of motion:

{ \bf{v = u + at}}

Change = v - u:

{ \tt{v - u = (a \times t)}} \\ { \tt{v - u = ( \frac{15}{22} \times 1.2) }} \\ { \tt{v - u = 0.82 \:  {ms}^{ - 2} }}
