It really doesn't matter whether the two masses are joined by a light string, a light reinforced concrete and steel frame, a light coating of strong glue, or a layer of scotch tape that's one atom thick. They look like a single mass of 10 kg.

Part a). Force = (mass) x (acceleration)

The acceleration of 10 kg of mass pulled with 100N of force is

100 N = (10 kg) x (acceleration)

Divide each side by (10 kg):

Acceleration = (100 N) / (10 kg)

Acceleration = 10 m/s²

Part b). Now look at just the rear 16 kg. It stays hooked onto the front 4 kg, and everything moves together. So both pieces must have the same distance, velocity, acceleration etc. We know that the acceleration is 10 m/s² .

Force = (mass) x (acceleration)

Force on the rear 16 kg = (16 kg) x (10 m/s²)

Force = 160 Newtons

What pressure will 14. 0 g of co exert in a 3. 5 l container at 75°c?

Ronch [10]

The pressure will 14. 0 g of co exert in a 3. 5 l container at 75°c is 4.1atm.

Therefore, option A is correct option.

Given,

Mass m = 14g

Volume= 3.5L

Temperature T= 75+273 = 348 K

Molar mass of CO = 28g/mol

Universal gas constant R= 0.082057L

Number of moles in 14 g of CO is

n= mass/ molar mass

= 14/28

= 0.5 mol

As we know that

PV= nRT

P × 3.5 = 0.5 × 0.082057 × 348

P × 3.5 = 14.277

P = 14.277/3.5

P = 4.0794 atm

P = 4.1 atm.

Thus we concluded that the pressure will 14. 0 g of co exert in a 3. 5 l container at 75°c is 4.1atm.

NEED ANSWER ASSAP

dusya [7]

An aspect of the event of various types of balls bouncing off the same floor, being matter is that all the balls consist of matter. They all occupy space and have a form of energy when moved by a force, such as a person. And for energy, like I just said, when they bounce they create energy as they bounce up and down, so if the ball were to hit some other object, it would have an impact on the still object.

) The potential difference between the plates of a capacitor is 400 V. (a) If the spacing between the plates is doubled without

kramer

(a) 800 V

The capacitance of a parallel-plate capacitor is given by

$C=\frac{\epsilon_0 A}{d}$

where

$\epsilon_0$ is the vacuum permittivity

A is the area of each plate

d is the separation between the plates

We see that the capacitance is inversely proportional to the separation, d: in this problem, the separation between the plates is doubled (2d), so the capacitance will become half of its original value:

$C'=\frac{C}{2}$

The potential difference between the plates is related to the capacitance by

$V=\frac{Q}{C}$ (1)

where Q is the charge stored on the plate. In this problem, the charge is not changed: therefore, the new potential difference is

$V'=\frac{Q}{C/2}=2\frac{Q}{C}=2V$

So, the potential difference has doubled, and since the initial value was

V = 400 V

The new value is

V' = 2(400) = 800 V

(b) The charge will decrease by a factor 2

As before, the plate spacing is doubled, so according to the equation

$C=\frac{\epsilon_0 A}{d}$

Then the capacitance is halved again:

$C'=\frac{C}{2}$

This time, however, the voltage is held constant. We can rewrite the eq.(1) as

Q = CV

And since V has not changed, we can find what is the new charge stored in the capacitor:

$Q' = C'V=\frac{C}{2}V=\frac{1}{2}(CV) = \frac{1}{2}Q$

So, the charge will be halved compared to the original charge.

SOUND IS A FORM OF WAVE.LIST AT LEAST 3 REASONS TO SUPPORT IDEA THAT SOUND IS A WAVE.

algol [13]

1 The question asks for a certain quantity of examples in a list (Name 6 factors that contributed to the start of World War I, What 3 subatomic particles constitute an atom? etc).
2 The question is academically precise and, therefore, indecisive in the wording (What are the 2 kinds of loading most professional engineers and academics in the field of engineering today generally consider to be relevant in most cases when considering typical types of structure usually made of common materials using well-understand methods?)
3 The question challenges the answerer to defend a position as opposed to merely rattling off a list based on knowledge alone, thereby invoking higher levels of Bloom's Taxonomy. (What are 4 arguments that could be used to defend arguments made by the physicists of the day that electromagnetic waves must move through an illusive substance called 'the ether?)
