If you drop a gum rapper on the floor is that pollution

Not exactly, it is littering. littering makes the place look unpleasing and unclean, but it wont necessarily kill us. now if a factory is dumping their sewage and whatnot in the water, that is considered as industrial pollution because it is killing almost all the wildlife that live in the water, and it can contaminate the water so if you take a swim in it and accidentally swallow some of the water, it can make you sick and can possibly kill you.

No pollution is in the air, dripping a gum wrapper on the floor is littering

Which does not represent a change in velocity?
alina1380 [7]

Answer:

A balloon is floating up into the air at 1 m/s.

Explanation:

Velocity is the displacement divided by the time;

   Velocity = \frac{displacement}{time}

It is a vector quantity that has magnitude and direction.

The choice that shows a change in direction is a correct specification of velocity.

A balloon floating up into the air at 1m/s shows no directional change.

Boxes A and B are in contact on a horizontal, frictionless surface. Box A has mass 21.0 kg and box B has mass 8.0 kg. A horizont
vfiekz [6]

Answer:

2.75 N

Explanation:

Given that,

Box A has a mass 21.0 kg and box B has a mass 8.0 kg.

A horizontal force of 100N is exerted on box A.

Let a be the acceleration of the system. Using second law of motion,

F=(m_A+m_B)a\\\\a=\dfrac{F}{(m_A+m_B)}\\\\a=\dfrac{10}{(21+8)}\\\\a=0.344\ m/s^2

Now applying Newton's second law to box B. So,

F_A=m_Ba\\\\=8\times 0.344\\\\=2.75\ N

So, 2.75 N is the force that box A exerts on box B.

3.1 * Consider a gun of mass M (when unloaded) that fires a shell of mass m with muzzle speed v. (That is, the shell's speed rel
kramer

Answer:

v_s=\frac{v}{1+\frac{m}{M} }

Explanation:

Let the shells speed with respect to ground be v_s

Let the shells speed with respect to ground be v_g

mass of shell, m

mass of gun, M

The relative velocity of shell with respect to a free unconstrained gun, v

According to the Newton's third law of motion the direction of the velocity of gun and shell will be in the opposite direction.

So, the relation between the relative velocity and their individual velocity will be:

v=v_s+v_g ......................(1)

<u>And according to the conservation of momentum (as the condition is very close to the elastic collision):</u>

M.v_g-m.v_s=0

substitute the value of v_g from equation (1)

M\times (v-v_s)=m\times v_s

M.v-M.v_s=m.v_s

M.v=M.v_s+m.v_s

v_s=\frac{M.v}{(M+m)}

v_s=\frac{v}{(\frac{(M+m)}{M}) }

v_s=\frac{v}{1+\frac{m}{M} }

Sergeu [11.5K]

B

A prominence is a large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's corona.
