Answer:
Boyle's Law
![\therefore P_1.V_1=P_2.V_2](https://tex.z-dn.net/?f=%5Ctherefore%20P_1.V_1%3DP_2.V_2)
Explanation:
Given that:
<u><em>initially:</em></u>
pressure of gas, ![= P_1](https://tex.z-dn.net/?f=%3D%20P_1)
volume of gas, ![= V_1](https://tex.z-dn.net/?f=%3D%20V_1)
<em><u>finally:</u></em>
pressure of gas, ![= P_2](https://tex.z-dn.net/?f=%3D%20P_2)
volume of gas, ![= V_2](https://tex.z-dn.net/?f=%3D%20V_2)
<u>To solve for final volume</u>
<em>According to Avogadro’s law the volume of an ideal gas is directly proportional to the no. of moles of the gas under a constant temperature and pressure.</em>
<em>According to the Charles' law, at constant pressure the volume of a given mass of an ideal gas is directly proportional to its temperature.</em>
But here we have a change in the pressure of the Gas so we cannot apply Avogadro’s law and Charles' law.
Here nothing is said about the temperature, so we consider the Boyle's Law which states that <em>at constant temperature the volume of a given mass of an ideal gas is inversely proportional to its pressure.</em>
Mathematically:
![P_1\propto \frac{1}{V_1}](https://tex.z-dn.net/?f=P_1%5Cpropto%20%5Cfrac%7B1%7D%7BV_1%7D)
![\Rightarrow P_1.V_1=k\ \rm(constant)](https://tex.z-dn.net/?f=%5CRightarrow%20P_1.V_1%3Dk%5C%20%5Crm%28constant%29)
![\therefore P_1.V_1=P_2.V_2](https://tex.z-dn.net/?f=%5Ctherefore%20P_1.V_1%3DP_2.V_2)
Answer:
0.8214 m/s^2
Explanation:
Fnet= Fpushed - Ffriction
Fpushed = 12.7N Ffriction = 8.33N
Fnet = 12.7N - 8.33N = 4.37N
Fnet= mass(acceleration)
Fnet = 4.37N mass = 5.32 kg
4.37N = 5.32 kg(acceleration)
acceleration= 0.8214 m/s^2
The phase of matter is the Solid Phase.
2) What must be connected for an electrical current to flow in a simple current?
<em>d.moving magnets,conductors, load to do work
</em>
here moving magnets will work as generator and conductors is used as connectors.
5)What is the purpose of a load in a circuit?
<em>c.provide resistance to keep the voltage strong
</em>
Load will provide the resistance to the circuit and help to build the voltage across it
6) What cause an electric current from a generator
<em>d.Magnets and conducting wires move near each other
</em>
here when magnets move near wires then it will induce the electric current and behaves like generators
7) What do all generators have in common
<em>b.they transform mechanical into electrical energy
</em>
They have magnets and rotating coils which will convert magnetic energy to electrical energy
8) How can we measure electrical current
<em>b.the pressure force is voltage;the # of electrons moving is amperes
</em>
this voltage and number of electrons will help to calculate current
The time elapsed is 9 seconds
Explanation:
The motion of the ball is a uniformly accelerated motion (a motion with constant acceleration), so we can use the following suvat equation:
where
:
v is the final velocity of the ball
u is the initial velocity
a is the acceleration
t is the time elapsed
For the ball in this problem, we have:
u = 3 m/s is the initial velocity
v = 34.5 m/s is the final velocity
is the acceleration
Solving for t, we find the time taken for this change in velocity:
![t=\frac{v-u}{a}=\frac{34.5-3}{3.5}=9 s](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bv-u%7D%7Ba%7D%3D%5Cfrac%7B34.5-3%7D%7B3.5%7D%3D9%20s)
