im not gonna write a research paper but this is the really easy way write global warming talk about animals the polar ice caps and water levels then for what causes it burning fossil fuels and energy plants. then finish off with its awful and we should use solar or geothermic or wind or when the time comes fusion not fission fusion makes helium from hydrogen then burylliam from helium then oxygen and silicon so on so forth instead of fissions uranium,plutonium and thorium and with radioactive waste

Weight = (mass) · (gravity)

Weight = (10 kg) · (9.8 m/s²)

Weight = (10 · 9.8) kg·m/s²

Weight = 98 Newtons

A box rests on the floor. If you pull sideways on the box with a 300 N force, but don't move it, what is the magnitude of the fr

Dahasolnce [82]

The magnitude of the frictional force is B) 300 N

Explanation:

For this problem, we just have to consider the forces acting on the box in the horizontal direction.

There are only two forces in this direction:

- The pull applied by the man, of magnitude F=300 N, forward

- The frictional force, $F_f$ , acting backward

So the equation of motion for the box is

$F-F_f = ma$

where

m is the mass of the box

a is its acceleration

However, the box is at rest, so its acceleration is zero:

a = 0

This means therefore that

$F-F_f=0$

And so the magnitude of the frictional force is equal to the pulling force:

$F_f = F = 300 N$

A hockey puck sliding on a frictionless surface strikes a box at rest. After the collision, the two objects stick together and m

coldgirl [10]

Answer:

Answer:

f) The puck conserves its original momentum but loses some, but not all, of its mechanical energy.

Explanation:

It is a case of perfectly inelastic collision . So momentum will be conserved because no external force acts on them during the collision . But there will be loss of energy ( kinetic energy ) . It will be in the form of sound or heat that is produced during collision. They will still have some kinetic energy even after the collision.

9. 2076 Set B Q.No. 9b Two galvanometers, which are otherwise identical; are fitted with different coils. One has coil of 50 tur

Hunter-Best [27]

The ratio of the deflection when each is connected in turns to a cell of e.m.f 25 V and internal resistance 50 ohms is 13: 12

<h3></h3><h3>What is internal resistance?</h3>

Internal resistance can be described as the resistance within a battery, or other voltage source, that causes a drop in the source voltage when there is a current.

The parameters given are :

Coil 1 = 50 turns

Coil 2 = 500 turns

Resistance 1 = 1022

Resistance 2 = 6002

Internal resistance = 50 ohms

Emf = 25v

I = 25/ 50+ 10

I = 25/60

I = 5/ 12 A

$I_{2}$ = 25/50+ 600

= 25/ 650

= 5/ 130 A

The ratio of the deflection when each is connected in turns to a cell of e.m. 25 V and internal resistance 50 ohms =

Q1/ Q2

Q1 = N1 x B x $I_{1}$ / c

Q2 = N2 x B x $I_{2}$ / c

therefore Q/ Q2 = (50 x 5/12 )/ (500 x 5/130)

Q1 / Q2 = 12/ 13 which 13: 12

Therefore, The ratio of the deflection when each is connected in turns to a cell of e.m. 25 V and internal resistance 50 ohms is 13: 12.
