Physics
1 answer:
tester [92]2 years ago
6 0

Answer:

55.5 degrees above the x-axis.

Explanation:

Using SOH-CAH-TOA we can determine that

tan(the angle) = (opposite side)/(adjacent side)

Inserting our variables we get

the angle = arctan(28.4/19.5)

the angle = 55.5 degrees

A wire carries a current of 4.1 A. How many electrons per second are passing any cross sectional area of the wire? Enter your an
aivan3 [116]

To solve this problem it is necessary to apply the concepts related to Current and Load.

The current in terms of the charge of an electron can be expressed as

i = \frac{q}{t}

Where,

q = Charge

t = time

At the same time the Charge is the amount of electrons multiplied by the amount of these, that is

q = ne

Replacing in the first equation we have to

i = \frac{q}{t}

i = \frac{ne}{t}

Clearing n,

n = \frac{it}{e}

Here the time is one second then

n = \frac{i}{e}

n = \frac{4.1}{1.6*10^{-9}}

n = 2.56*10^{19}electrons

Therefore the number of electrons per second are passing any cross sectional area of the wire are 2.56*10^{19}electrons

Does the thickness of the wire affect the strength of an electroscope
TiliK225 [7]
It probably does. I'm not 100% sure about it, but a thicker wire would increase the number of positive and negative charges in it.

A boy on the beach holds a spherical balloon filled with air. at 10:00am, the temperature on the beach is 20°c and the balloon h
Anon25 [30]
For idea gases, volume is directly proportional to temperature. That is, an increase in temperature leads to increase in volume and vice versa.

Therefore,
V1/T1 = V2/T2 => T2 = (V2*T1)/V1

Assuming that the balloon is spherical in shape,

V= 4/3*pi*R^3.... In the formula for calculating T2, 4/3*pi cancels out.

R1 = 30/2 15 cm; R2 = 30.5/2 = 15.25 cm; T1 = 20+273.15 =293.15 K

Therefore,

T2 = (R2^3*T1)/R1^3 = (15.25^3*293.15)/15^3 = 308.05 K = 34.9 °C

Which of the following statements correctly describes the position of the intake and exhaust valves during most of the power sta
I am Lyosha [343]

Both valves are closed during the power stroke.

While the fuel is burning in the cylinder, you want
all the force of the expanding gases to push the
piston down ... you don't want any of the gases
or their pressure escaping. 

If either of the valves was open, even just a crack,
then part of the gases would go blooey out the valve,
and some pressure would be lost that's supposed to be
pushing the piston.

The ability of solid rock to flow is called _____.
zysi [14]
The ability of solid rock to flow is called Plasticity.

Plasticity is the deformation of a solid mateial which resulted in non reversible changes of shape in response to applied force.

Another example of plasticity is when you bend metal through a forcer force to create an art or kitchen set
