What does the measurement 6.5 V represent?
WITCHER [35]
I'm not sure.
Where did you see it ?

If you saw it on a voltmeter, then it stands for "6.5 volts".
It tells you that the 'potential difference' or 'electromotive force'
between the two points connected to the meter is 6.5 volts.

-- If a 1-ohm resistor were connected between those two points,
then 6.5 coulombs of charge would move through the resistor every
second.  We would say that the "current" through the resistor is
6.5 Amperes, or "six'na half amps".

-- Each coulomb of charge (6.25 x 10¹⁸ electrons) that moves from
one of those points to the other one either gains or loses 6.5 joules
of energy, depending on which direction it moves.

-- So the resistor would need to shed heat somehow, at the rate of
6.5 watts (6.5 joules per second).  If it couldn't do that, then it would
go through an interesting series of changes.  It would get warm, then
get hot, then glow cherry red, then glow bright red, then glow orange,
then glow bright yellow, then make a sound like a "POP".  Then it would
break in the middle, and a little wisp of smoke would come out of it.
The two halves of the resistor would sink, sag from their wires, and
the current between the two points would stop. 

We would say that the resistor had "fused", "failed", "melted", "burned out",
or "bought the farm" ... all because it couldn't get rid of heat fast enough.

A soft-drink bottler purchases glass bottles from a vendor. The bottles are required to have internal pressure strength of at le
maria [59]

Answer: K =24 psi

Explanation:

Given: Standard deviation =3psi

Internal pressure strength =157psi

Number of random bottle =n=64

K= 3 × square root of 64

K= 3×8=24 psi

If mean internal pressure K fall below K,

157-1.3=155.7psi

At 2%:

0.16×64 = 10.24

The forces in (Figure 1) are acting on a 1.0 kg object.What is ax , the x -component of the object's acceleration
a_sh-v [17]

The x -component of the object's acceleration is 2 m/s².

<h3>What's the resultant force along x- direction?</h3>
  • Forces along x axis direction are as follows
  1. 4N along +x axis, so it's taken as +4 N
  2. 2N along -x axis , so it's taken as -2N.
  • Resultant force along x direction = 4N - 2N = 2 N which is along + ve x direction.

<h3>What's the acceleration along x axis direction?</h3>
  • As per Newton's second law, Force = mass × acceleration of the object
  • Force along x axis= mass × acceleration along x axis= 2N
  • Acceleration = 2/ mass = 2/1 = 2 m/s²

Thus, we can conclude that the acceleration along x axis is 2 m/s².

I NEED HELP ASAP!!!!!
Ratling [72]

Answer:

D) momentum of cannon + momentum of projectile= 0

Explanation:

The law of conservation of momentum states that the total momentum of an isolated system is constant.

In this case, the system cannon+projectile can be considered as isolated, because no external forces act on it (in fact, the surface is frictionless, so there is no friction acting on the cannon). Therefore, the total momentum of the two objects (cannon+projectile) must be equal before and after the firing:

p_i = p_f

But the initial momentum is zero, because at the beginning both the cannon and the projectile are at rest:

p_i = 0

So the final momentum, which is sum of the momentum of the cannon and of the projectile, must also be zero:

p_f = p_{cannon}+p_{projectile} =0
